which is better oled or lcd screen free sample

For all the new technologies that have come our way in recent times, it’s worth taking a minute to consider an old battle going on between two display types. Two display types that can be found across monitors, TVs, mobile phones, cameras and pretty much any other device that has a screen.

In one corner is LED (light-emitting diode). It’s the most common type of display on the market, however, it might be unfamiliar because there’s slight labelling confusion with LCD (liquid crystal display).

For display purposes the two are the same, and if you see a TV or smartphone that states it has an ‘LED’ screen, it’s an LCD. The LED part just refers to the lighting source, not the display itself.

In a nutshell, LED LCD screens use a backlight to illuminate their pixels, while OLED’s pixels produce their own light. You might hear OLED’s pixels called ‘self-emissive’, while LCD tech is ‘transmissive’.

The light of an OLED display can be controlled on a pixel-by-pixel basis. This sort of dexterity isn’t possible with an LED LCD – but there are drawbacks to this approach, which we’ll come to later.

In cheaper TVs and LCD-screen phones, LED LCD displays tend to use ‘edge lighting’, where LEDs sit to the side of the display, not behind it. The light from these LEDs is fired through a matrix that feeds it through the red, green and blue pixels and into our eyes.

LED LCD screens can go brighter than OLED. That’s a big deal in the TV world, but even more so for smartphones, which are often used outdoors and in bright sunlight.

Brightness is generally measured as ‘nits’ – roughly the light of a candle per square metre. Brightness is important when viewing content in ambient light or sunlight, but also for high dynamic range video. This applies more to TVs, but phones boast credible video performance, and so it matters in that market too. The higher the level of brightness, the greater the visual impact.

Take an LCD screen into a darkened room and you may notice that parts of a purely black image aren’t black, because you can still see the backlighting (or edge lighting) showing through.

Being able to see unwanted backlighting affects a display’s contrast, which is the difference between its brightest highlights and its darkest shadows.

You’ll often see a contrast ratio quoted in a product’s specification, particularly when it comes to TVs and monitors. This tells you how much brighter a display’s whites are compared to its blacks. A decent LCD screen might have a contrast ratio of 1,000:1, which means the whites are a thousand times brighter than the blacks.

Contrast on an OLED display is far higher. When an OLED screen goes black, its pixels produce no light whatsoever. That means an infinite contrast ratio, although how great it looks will depend on how bright the screen can go. In general, OLED screens are best suited for use in darker rooms, and this is certainly the case where TVs are concerned.

OLED panels enjoy excellent viewing angles, primarily because the technology is so thin, and the pixels are so close to the surface. You can walk around an OLED TV or spread out in different spots in your living room, and you won’t lose out on contrast. For phones, viewing angles are extra important because you don’t tend to hold your hand perfectly parallel to your face.

Viewing angles are generally worse in LCDs, but this varies hugely depending on the display technology used. And there are lots of different kinds of LCD panel.

Perhaps the most basic is twisted nematic (TN). This is the type used in budget computer monitors, cheaper laptops, and very low-cost phones, and it offers poor angled viewing. If you’ve ever noticed that your computer screen looks all shadowy from a certain angle, it’s more than likely it uses a twisted nematic panel.

Thankfully, a lot of LCD devices use IPS panels these days. This stands for ‘in-plane switching’ and it generally provides better colour performance and dramatically improved viewing angles.

IPS is used in most smartphones and tablets, plenty of computer monitors and lots of TVs. It’s important to note that IPS and LED LCD aren’t mutually exclusive; it’s just another bit of jargon to tack on. Beware of the marketing blurb and head straight to the spec sheet.

The latest LCD screens can produce fantastic natural-looking colours. However, as is the case with viewing angles, it depends on the specific technology used.

OLED’s colours have fewer issues with pop and vibrancy, but early OLED TVs and phones had problems reining in colours and keeping them realistic. These days, the situation is better, Panasonic’s flagship OLEDs are used in the grading of Hollywood films.

Where OLED struggles is in colour volume. That is, bright scenes may challenge an OLED panel’s ability to maintain levels of colour saturation. It’s a weakness that LCD-favouring manufacturers enjoy pointing out.

Both have been the subject of further advancements in recent years. For LCD there’s Quantum Dot and Mini LED. The former uses a quantum-dot screen with blue LEDs rather than white LEDs and ‘nanocrystals’ of various sizes to convert light into different colours by altering its wavelength. Several TV manufacturers have jumped onboard Quantum Dot technology, but the most popular has been Samsung’s QLED branded TVs.

Mini LED is another derivation of LED LCD panels, employing smaller-sized LEDs that can emit more light than standard versions, increasing brightness output of the TV. And as they are smaller, more can be fitted into a screen, leading to greater control over brightness and contrast. This type of TV is becoming more popular, though in the UK and Europe it’s still relatively expensive. You can read more about Mini LED and its advantages in our explainer.

OLED, meanwhile, hasn’t stood still either. LG is the biggest manufacturer of large-sized OLED panels and has produced panels branded as evo OLED that are brighter than older versions. It uses a different material for its blue OLED material layer within the panel (deuterium), which can last for longer and can have more electrical current passed through it, increasing the brightness of the screen, and elevating the colour volume (range of colours it can display).

Another development is the eagerly anticipated QD-OLED. This display technology merges Quantum Dot backlights with an OLED panel, increasing the brightness, colour accuracy and volume, while retaining OLED’s perfect blacks, infinite contrast and potentially even wider viewing angles, so viewers can spread out anywhere in a room and see pretty much the same image. Samsung and Sonyare the two companies launching QD-OLED TVs in 2022.

And for smartphones there’s been a move towards AMOLED (Active-Matrix Organic Light Emitting Diode) screens for Android screens, while Apple has moved towards OLED for its smartphones and tried Mini LED with its iPad Pro. Technologies are consistently evolving with Superand Dynamic AMOLED versions available, more performance is being eked out.

While LED LCD has been around for much longer and is cheaper to make, manufacturers are beginning to move away from it, at least in the sense of the ‘standard’ LCD LED displays, opting to explore the likes of Mini LED and Quantum Dot variations.

OLED has gained momentum and become cheaper, with prices dipping well below the £1000 price point. OLED is much better than LED LCD at handling darkness and lighting precision, and offers much wider viewing angles, which is great for when large groups of people are watching TV. Refresh rates and motion processing are also better with OLED though there is the spectre of image retention.

If you’re dealing with a limited budget, whether you’re buying a phone, a monitor, a laptop or a TV, you’ll almost certainly end up with an LCD-based screen. OLED, meanwhile, incurs more of a premium but is getting cheaper, appearing in handheld gaming devices, laptops, some of the best smartphones as well as TVs

Which is better? Even if you eliminate money from the equation, it really comes down to personal taste. Neither OLED nor LCD LED is perfect. Some extol OLED’s skill in handling darkness, and its lighting precision. Others prefer LCD’s ability to go brighter and maintain colours at bright levels.

How do you decide? Stop reading this and go to a shop to check it out for yourself. While a shop floor isn’t the best environment in which to evaluate ultimate picture quality, it will at least provide an opportunity for you to realise your priorities. Whether you choose to side with LCD or OLED, you can take comfort in the fact that both technologies have matured considerably, making this is a safe time to invest.

Shopping for a new TV sounds like it could be fun and exciting — the prospect of a gleaming new panel adorning your living room wall is enough to give you goosebumps. But with all the brands to choose from, and different smart capabilities (we can explain what a smart TV is) to weigh, as well as the latest picture tech to consider, it can be daunting. Is this article, we compare OLED vs. LED technology to see which is better for today’s modern TVs. Once you determine which panel type is best for you, make sure you check out our list of the best TVs to get our editor’s recommendations.

If you’re in the market for a TV, you’ve likely heard the hype regarding OLED models. They’re thin, light, and offer incredible contrast and color that’s second to none. OLED is only one letter apart from the more common display type, LED, so what gives? Can they really be that different? In a word: Yes. That extra “O” makes a big difference, but it doesn’t automatically mean an OLED TV will beat an LED TV in every use case. Some TV manufacturers like Samsung use their own technology, called QLED to confuse consumers even more. Make sure that you spend some time looking at our comparison piece: QLED vs. OLED technology before you make your purchase decision.

When OLED TVs first arrived in 2013, they were lauded for their perfect black levels and excellent color, but they took a bit of a hit due to brightness levels that couldn’t compete with LED TVs. There was also a huge price gap between OLED TVs (not to be confused with QLED) and their premium LED counterparts. In fact, legend has it that OLED used to mean “only lawyers, executives, and doctors” could afford them. Thankfully, that’s no longer the case.

OLED TVs are much brighter than they used to be, and the prices have come down, especially with brands like Sony introducing competitive options in 2021. The LED market is due for a bit of a shake-up, too. For now, however, it’s time to take a look at how these two technologies differ and explore the strengths and weaknesses of each.

Non-OLED TVs are made of two main parts: An LCD panel and a backlight. The LCD panel contains the pixels, the little colored dots that make up a TV’s image. On their own, pixels cannot be seen; they require a backlight. When light from the backlight shines through an LCD pixel, you can see its color.

The “LED” in LED TV simply refers to how the backlight is made. In the past, a thicker and less-efficient technology called CCFL (cold-cathode fluorescent light) was used. But these days, virtually every flat-screen TV uses LEDs as its source of backlighting. Thus, when you see the term “LED TV,” it simply refers to an LED-backlit LCD TV.

That said, not all LED TVs are created equal. There can be differences in the number and quality of the LEDs used, which leads to differences in things like brightness and black levels. You may also have seen something called “QLED TV.” This is a type of LED TV that uses quantum dots to achieve better brightness and color. We’ll discuss QLED more below, but here’s a great overview of the differences between QLED and OLED TVs.

The “OLED” in OLED TV stands for “organic light-emitting diode.” OLEDs have the unusual property of being able to produce both light and color from a single diode when they’re fed electricity. Because of this, OLED TVs don’t need a separate backlight. Each pixel you see is a self-contained source of color and light.

Some of the inherent benefits of OLED screens are that they can be extremely thin, flexible, and even rollable. But the biggest benefit when we compare them to LED TVs is that each individual pixel receives its own luminance and power (as opposed to LED TVs, which have persistent pixels that require an external source of light to see). When it’s on, you can see it. When it’s off, it emits no light at all — it’s completely black. We’ll discuss how this affects black levels in a moment.

Currently, LG Display is the only manufacturer of OLED panels for TVs, famed for top-line models like the CX. Sony and LG have an agreement that allows Sony to put LG OLED panels into Sony televisions — like the bright X95OH — but otherwise, you won’t find OLED in many other TV displays sold in the U.S.

The differences in performance between LG’s OLED TVs and Sony’s result from different picture processors at work. Sony and LG have impressive processors that are also unique to each brand, which is why two TVs with the same panel can look drastically different. A good processor can greatly reduce issues like banding and artifacting and produce more accurate colors as well.

Other brands that source panels from LG include Philips, Panasonic, HiSense, Bang & Olufsen, and more. You’ll also see lesser-known brands sparingly, but for now, they’re all getting their panels from the same source.

Samsung does make OLED smartphone panels, and the company recently announced it would start building new TV panels based on a hybrid of QLED and OLED known as QD-OLED, but it will be a few more years before we see the first TVs that use this technology.

Though they don really similar acronyms, an OLED TV is not the same as a QLED TV. The latter is actually based on LED tech, but it uses a technique that overlays self-emissive quantum dots over the pixels that help produce better brightness, vividness, and color accuracy. QLED is more of an iterative step than a generational leap, and though we’d certainly recommend buying one if OLED is out of reach, expect its eventual deprecation as technologies like quantum dot OLED (QD-OLED) and microLED take hold.

Despite the name, microLED has more in common with OLED than LED. Created and championed by Samsung, this technology creates super-tiny, modular LED panels that combine light emission and color like OLED screens do, minus the “organic” part. For now, the technology is primarily being used for extra-large wall TVs, where colors, blacks, and off-angle viewing are excellent but with more potential for greater brightness and durability than OLED TVs.

For the average consumer, microLED isn’t anything to consider yet. It remains difficult to scale down to less-than-gigantic TVs, and it’s unlikely to hit homes for another couple of years when it will still be exceedingly expensive. Of course, that was once true of OLED, which is why this tech is worth keeping an eye on for a future TV replacement.

Now it’s time to pit these two technologies against each other and see how they stack up when it comes to traits such as contrast, viewing angle, brightness, and other performance considerations.

Editor’s note: Since OLED TVs are still a premium display, we have compared OLED only to equally-premium LED TVs armed with similar performance potential (except, of course, in the price section).

A display’s ability to produce deep, dark blacks is arguably the most important factor in achieving excellent picture quality. Deeper blacks allow for higher contrast and richer colors (among other things) and thus a more realistic and dazzling image. When it comes to black levels, OLED reigns as the undisputed champion.

LED TVs rely on LED backlights shining behind an LCD panel. Even with advanced dimming technology, which selectively dims LEDs that don’t need to be on at full blast, LED TVs have historically struggled to produce dark blacks and can suffer from an effect called “light bleed,” where lighter sections of the screen create a haze or bloom in adjacent darker areas.

OLED TVs suffer from none of the black-level problems of traditional LED TVs. If an OLED pixel isn’t getting electricity, it doesn’t produce any light and is, therefore, totally black. Sounds like an obvious choice to us.

When it comes to brightness, LED TVs have a considerable advantage. Their backlights can be made from large and powerful LEDs. With the addition of quantum dots, that brightness can be preserved even as the size of the individual LEDs get smaller. OLED TVs can get pretty bright, too, and with such dark black levels, the contrast between the brightest and darkest spots on screen is all the more exaggerated. But cranking OLED pixels to their maximum brightness for extended periods reduces their lifespan, and the pixel takes slightly longer to return to total black.

With those considerations in mind, it’s important to note that all modern TVs — whether OLED, LED, or QLED — produce more than adequate brightness. The consideration then becomes where the TV will be used. In a dark room, an OLED TV is going to perform best, while LED TVs will outshine them (quite literally) in more brightly lit environments.

It should also be noted that there have been big gains recently in OLED brightness, making them perfectly suitable for nearly any situation, save direct sunlight beaming onto the screen. Still, when compared directly, LED TVs have the edge.

OLED used to rule this category, but by improving the purity of the backlight, quantum dots have allowed LED TVs to surge forward in color accuracy, color brightness, and color volume, putting them on par with OLED TVs. Those looking for TVs with Wide Color Gamut or HDR will find both OLED and LED TV models that support these features. OLED’s better contrast ratio is going to give it a slight edge in terms of HDR when viewed in dark rooms, but HDR on a premium LED TV screen has an edge because it can produce well-saturated colors at extreme brightness levels that OLED can’t quite match.

Response time refers to the time it takes for each individual pixel to change states. A pixel’s state is not only its color but also its brightness. With a faster response time, you get less motion blur and fewer artifacts (source material notwithstanding).

Because OLED pixels combine the light source and the color in a single diode, they can change states incredibly fast. By contrast, LED TVs use LEDs to produce brightness and tiny LCD “shutters” to create color. While the LED’s brightness can be changed in an instant, LCD shutters are by their nature slower to respond to state changes.

Refresh rate is how often the entire image on-screen changes. The faster the rate, the smoother things look, and the easier it is to pick out details in fast-moving content like sports. Most new TVs are capable of refresh rates of 120Hz, which means the entire image is updated 120 times every second. Some go as high as 240Hz.

If refresh rate were simply a matter of Hz, we’d call OLED TV the winner, simply because it can achieve rates of up to 1,000 times higher than LED TVs. But absolute speed isn’t the only consideration. Unlike movies and TV shows, which use a single refresh rate, video games often employ something called variable refresh rates, which simply means that the rate changes during different parts of a game. If a TV can’t match these rate changes, you end up with image tearing — a visible jerkiness that comes from the disparity between the rate the game is using and the rate the TV wants to use.

That’s why gamers, in particular, want TVs that can handle VRR or Variable Refresh Rate. It’s a rare feature on both OLED and LED TVs, but you can expect to see it show up on more models in both types of TVs. Right now, you can find VRR in certain Samsung, LG, and TCL TVs. But neither OLED nor LED TVs have a real advantage when it comes to VRR; some models have the feature, and some don’t. Your gaming system also has to support VRR, though that shouldn’t be much of an issue if you own a new Xbox Series X, PS5, or even a PS4/One X.

Finally, input lag is the gap in time between when you press a button on a game controller and the corresponding action shows up on-screen. Input lag can be a problem when TVs introduce a lot of picture processing that causes a slow-down in the signal they receive. But most modern TVs have a game mode, which eliminates the processing and reduces input lag to barely discernible levels. In the future, all TVs will be able to sense the presence of a video game and switch to this mode automatically, returning to the processed mode when gaming stops.

OLED, again, is the winner here. With LED TVs, the best viewing angle is dead center, and the picture quality diminishes in both color and contrast the further you move to either side. While the severity differs between models, it’s always noticeable. For its LED TVs, LG uses a type of LCD panel known as IPS, which has slightly better off-angle performance than VA-type LCD panels (which Sony uses), but it suffers in the black-level department in contrast to rival VA panels, and it’s no competition for OLED. Samsung’s priciest QLED TVs feature updated panel design and anti-reflective coating, which make off-angle viewing much less of an issue. While OLED still beats these models out in the end, the gap is closing quickly.

That said, OLED TVs can be viewed with no luminance degradation at drastic viewing angles — up to 84 degrees. Compared to most LED TVs, which have been tested to allow for a max viewing angle of 54 degrees at best, OLED has a clear advantage.

OLEDs have come a long way in this category. When the tech was still nascent, OLED screens were often dwarfed by LED/LCD displays. As OLED manufacturing has improved, the number of respectably large OLED displays has increased — now pushing 88 inches — but they’re still dwarfed by the largest LED TVs, which can easily hit 100 inches in size, and with new technologies, well beyond.

What size TV do you need? Here are a few tips for picking the right size TV for any room, including ideal viewing distance and picture quality versus size.

LG says you’d have to watch its OLED TVs five hours a day for 54 years before they’d fall to 50% brightness. Whether that’s true remains to be seen, as OLED TVs have only been out in the wild since 2013. For that reason and that reason only, we’ll award this category to LED TVs. It pays to have a proven track record.

Can one kind of TV be healthier for you than another? If you believe that we need to be careful about our exposure to blue light, especially toward the evening, then the answer could be yes. Both OLED and LED TVs produce blue light, but OLED TVs produce considerably less of it. LG claims its OLED panels only generate 34% blue light versus LED TV’s 64%. That stat has been independently verified, and LG’s OLED panels have been given an Eye Comfort Display certification by TUV Rheinland, a standards organization based out of Germany.

Will it make a difference to your overall health? We think the jury is still out, but if blue light is a concern, you should take a serious look at OLED TVs.

The effect we’ve come to know as burn-in stems from the days of the boxy CRT TV when the prolonged display of a static image would cause an image to appear to “burn” into the screen. What was actually happening was the phosphors that coated the back of the TV screen would glow for extended periods of time without any rest, causing them to wear out and create the appearance of a burned-in image. We think this should be called “burn out,” but we’ll set that one aside.

The same issue is at play with plasma and OLED TVs because the compounds that light up can degrade over time. If you burn a pixel long and hard enough, it will dim prematurely ahead of the rest of the pixels, creating a dark impression. In reality, this is not very likely to cause a problem for most people — you’d have to abuse the TV intentionally to get it to happen. Even the “bug” (logographic) that certain channels use disappears often enough or is made clear to avoid causing burn-in issues. You’d have to watch ESPN all day, every day for a long, long time at the brightest possible setting to cause a problem, and even then, it still isn’t very likely.

That said, the potential is there, and it should be noted. (This is also a contributing factor in the dearth of OLED computer monitors on the market, as computer screens are far more likely to display a static image for hours on end.) Since LED TVs aren’t susceptible to burn-in, they win this fight by a technicality.

OLED panels require no backlight, and each individual pixel is extremely energy-efficient. LED TVs need a backlight to produce brightness. Since LEDs are less energy-efficient than OLEDs, and their light must pass through the LCD shutters before it reaches your eyes, these panels must consume more power for the same level of brightness.

OLED TVs are premium TVs and almost always likely to be more expensive than an LED version of the same size. However, we have seen prices starting to drop down to manageable levels recently, especially if there are any discounts running. MSRPs can go as low as $1,300 to $1,500, but you probably won’t find many lower than that.

Conversely, LED TVs can range in price from a few hundred dollars — even for a quality big-screen model — to several thousand dollars, making them overall more accessible than OLEDs. While prices of the highest-quality LED TVs hover at nearly the same range as the price of OLEDs, when judged by price and price alone, LED TVs can still be acquired for a pittance in comparison.

In terms of picture quality, OLED TVs still beat LED TVs, even though the latter technology has seen many improvements of late. OLED is also lighter and thinner, uses less energy, offers the best viewing angle by far, and, though still a little more expensive, has come down in price considerably. OLED is the superior TV technology today. If this article were about value alone, LED TV would still win, but OLED has come a long way in a short time and deserves the crown for its achievements. Regardless of which technology you ultimately decide on, that’s not the only factor that you need to consider, so be sure to check our TV buying guide to make sure you’re buying the right TV to meet your needs.

If you need to repair your phone screen you may have been looking into different types of screen replacements. You’ve probably heard of the acronyms LCD and OLED in TVs before, but what are the differences between LCD and OLED screens and what will be best for your phone?

LCD or Liquid Crystal Display has been the standard for computer, tablet, and phone screens for the past decade. These screens offer great brightness, high definition, and are becoming relatively inexpensive. We tend to see LCD screens on the less expensive cell phone models, today. LCD screens can have great HD quality and have good performance in direct sunlight but tend to be more inefficient when it comes to power consumption compared to an OLED screen.

Over the past few years, many companies have been switching to newer screen technology: OLED displays. OLED, which stands for organic light-emitting diode, is being used on all of the latest flagship devices. They tout amazing contrast of color, they’re lighter and flexible and tend to be more efficient than LCDs. OLED technology is being used for curved edge phones like theGalaxy S10+and theGalaxy S20, S20+, and S20 Ultra 5G. OLEDs have also been used in folding smartphone displays like theSamsung Galaxy Fold, the newMotorola razrsmart flip phone, and theSamsung Galaxy Z Flip.

OLED displays are being used by Apple in their iPhone 11 Pro Max, 11 Pro, XS Max, XS, and X. iPhone X flagship series and newer will come with OLED. Both flagship Samsung Galaxy S and Note Series have OLED displays as the standard on all recent devices including the Samsung Galaxy S10 and Note 10 series, S9+, S9, Note 9, S8, S8+, Note 8, and so on. These phones also all have OLED displays: LG V40, LG V30, Huawei P30 Pro, Huawei Mate 20 Pro, OnePlus 6T, and the Motorola Moto Z2 Force Edition.

The iPhone 11 and the XR still use LCD displays as well as all other iPhones that came before the X series including the iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6s, and so on. Basically, any iPhone with a Home Button will have a LCD screen on it. The LG G7 ThinQ, LG G6, Moto E5, and Moto E6 all have LCD displays as well.

When getting your device repaired, it is a good idea to use the display type that was originally installed on your phone. For example, if you have the iPhone X, which comes with an OLED display, ideally, you will want to get an OLED replacement. This will keep your phone running as efficiently as possible. If you need a more economical solution it is sometimes possible to get an LCD replacement, but keep in mind that they can drain your battery faster and may not have the same color contrast and may not be optimized for your phone.

One of the easiest ways to determine which display type you have is to go to a true black screen – you can search for this on Google Images. If your display type is LCD your pixels will still be displaying a dark gray light. If you have an OLED display the screen will be totally black. It is easier to tell when this experiment is performed in a dark room. You can also searchGSMArenafor your phone and then view its display type.

If you further subdivide the material of the screen, LCD and OLED can also be divided into many small classes. Due to the early development of LCD technology and the maturity of technology, there are many types of LCDs , and OLEDs have only emerged in recent years. OLED screens are mainly AMOLED , Super AMOLED and PMOLED .

At present, LCD screens on the market can be divided into hard screen, semi-hard screen and soft screen. The screen on the mobile phone tablet is covered with a glass touch layer, so the screen material cannot be touched. If the touch screen material can touch the screen of the computer. Or the screen of the TV.

The LCD soft screen is mainly TN , MVA , PVA, etc. The semi-hard screen is represented by LG "s IPS , and the hard screen is represented by Sharp"s ASV , or other small types. The most commonly used LCD screens on mobile phones are IPS , PLS, etc., and some very low-end machines can also be seen using TN screens. TN screens are cheap but have poor viewing angles.

If you follow the principles say, LCD and OLED the simplest difference is that if self-luminous, due to the characteristics of OLED, OLED screen no backlight, each pixel screen is capable of emitting light, so that the benefits brought about higher contrast, and in The black performance of the OLED screen has an inherent advantage, can achieve a full black display that does not emit light, and this will also make the power consumption of the screen lower than the LCD .

Since the OLED does not require a backlight, the OLED screen can be made thinner, which means that the thickness of the mobile phone can also be reduced when used on a mobile phone. Of course, the thickness of the mobile phone is not the thickness of the screen alone. At present, there are many mobile phones that use OLED screens but the thickness is not low. There are also mobile phones with LCD screens that have a slim body. The thickness of the mobile phone depends on the mobile phone. The overall design, the screen is not a decisive factor.

The LCD screen screen requires a backlight source, because the LCD screen does not self-illuminate like an OLED , and the LCD brings different colors by adjusting the angle of the liquid crystal molecules. LCD backlights do not allow the contrast to reach the level of OLEDs , but with the development of LCD technology, LCD screens can achieve better contrast.

When Samsung introduced AMOLED in the early days , it was often criticized by users and the color was too bright, and the saturation of the color was particularly high. OLED has been developed for many years. Although it has improved a lot in color performance, it still has the problem of high color saturation. The color is particularly bright, which is particularly attractive to some users. It may be difficult for some users to adapt.

The color of the LCD will be relatively natural, which is related to the color mechanism of the LCD itself. The LCD screen usually compensates for the red color and suppresses the green color to make the displayed color more realistic. One might argue that the LCD color gamut less than OLED, but what is certain is that the current high-end LCD has been able to achieve better color gamut on the market of high-end professional displays are basically LCD screen, after all, the true color for professional work Restore is the most important thing.

Since OLEDs emit light at every pixel, it means that each pixel is an independent LED light-emitting point, which may not be as good as a whole LCD for reliability . There are already many examples of " burning screen " and discoloration on mobile phones. On the one hand, it is the reliability of OLED screen quality . On the other hand, as the use time increases, the OLED screen is colored, broken, etc. The problem. With many mid-range mobile phones using OLED screens, the price of these mobile phones may be very strict. The quality of OLED screens may be less than that of OLED screens on flagship mobile phones. It may be more prone to problems when used for a long time.

LCD screen LCDs generally have a long service life. For example, a computer LCD monitor or a flat-panel TV can last for more than 10 years. Of course, the LCD screen on a mobile phone can theoretically last for more than 10 years. The problems with LCD screens are mostly backlight problems. As the use time increases, the backlight source of the screen will age and the brightness will decrease. However, as long as the liquid crystal layer is not bad, the LCD reliability of the screen is better than that of OLED .

The topic of DC dimming on OLED screens has been very hot. Many mobile phone manufacturers have equipped them with DC dimming function for mobile phones using OLED screens , and DC dimming can effectively reduce the stroboscopic problem of OLCD screens. Then, the LCD screen indicates that I am a natural DC dimming.

The OLED strobe problem has been around for a long time, but we usually don"t notice the strobe frequency when we look at the OLED screen. When it comes to strobe, it is necessary to understand the dimming principle of OLED screens. Since the OLED screen generates a jelly effect at a low voltage, the same method of lowering the voltage of the LCD to adjust the brightness of the screen cannot be used , and only the switching method can be used to adjust the brightness.

In the case of high brightness, the switching frequency of the OLED is very high, so the naked eye can hardly feel the stroboscopic occurrence, but in the case of low brightness, the switching frequency of the screen will decrease, and the too low strobe will cause people to produce The problem of fatigue, dizziness, headache, etc., is not conducive to health. In view of this , DC dimming of OLED screens has emerged.

Now the DC dimming used on the OLED screen is not very mature. There may be some minor problems. When we actually tested a mobile phone with DC dimming , we found that the brightness of the screen will decrease after DC dimming is turned on . Although there is no color cast when the three primary colors are compared, there is a case where the brightness is lowered.

For OLED screen, the biggest advantage is probably saving, thin and colorful (this may be a disadvantage), with the growing popularity of OLED because mobile phone manufacturers willing to choose the one hand, OLED OLED seems "tall on "On the other hand perhaps OLED thinner, more conducive to stack inside the phone, but still less than the LCD OLED mature, less reliability or LCD good.

For the LCD , although there is no OLED screen to save power, no OLED screen thin, but natural color performance is its biggest selling point, and has a natural DC dimming, no stroboscopic problems. LCD mature technology has become the choice of many mobile phone manufacturers, but with the popularity of OLED , the use of LCD screens has become less and less seen on the flagship machine . Many netizens have even called out the slogan "LCD is never a slave " . LCD also has its own charm, but only people who appreciate it are less and less.

There are plenty of new and confusing terms facing TV shoppers today, but when it comes down to the screen technology itself, there are only two: Nearly every TV sold today is either LCD or OLED.

The biggest between the two is in how they work. With OLED, each pixel provides its own illumination so there"s no separate backlight. With an LCD TV, all of the pixels are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.

LCDs are made by a number of companies across Asia. All current OLED TVs are built by LG Display, though companies like Sony and Vizio buy OLED panels from LG and then use their own electronics and aesthetic design.

So which one is better? Read on for their strengths and weaknesses. In general we"ll be comparing OLED to the best (read: most expensive) LCD has to offer, mainly because there"s no such thing as a cheap OLED TV (yet).

Take this category with a grain of salt. Both TV types are very bright and can look good in even a sunny room, let alone more moderate indoor lighting situations or the dark rooms that make TV images look their best. When it comes down to it, no modern TV could ever be considered "dim."

At the other side of light output is black level, or how dark the TV can get. OLED wins here because of its ability to turn off individual pixels completely. It can produce truly perfect black.

The better LCDs have local dimming, where parts of the screen can dim independently of others. This isn"t quite as good as per-pixel control because the black areas still aren"t absolutely black, but it"s better than nothing. The best LCDs have full-array local dimming, which provides even finer control over the contrast of what"s onscreen -- but even they can suffer from "blooming," where a bright area spoils the black of an adjacent dark area.

Here"s where it comes together. Contrast ratio is the difference between the brightest and the darkest a TV can be. OLED is the winner here because it can get extremely bright, plus it can produce absolute black with no blooming. It has the best contrast ratio of any modern display.

Contrast ratio is the most important aspect of picture quality. A high contrast-ratio display will look more realistic than one with a lower contrast ratio.

One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center (as in, off to the sides). How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones.

A few LCDs use in-plane switching (IPS) panels, which have better off-axis picture quality than other kinds of LCDs, but don"t look as good as other LCDs straight on (primarily due to a lower contrast ratio).

OLED doesn"t have the off-axis issue LCDs have; its image looks basically the same, even from extreme angles. So if you have a wide seating area, OLED is the better option.

Nearly all current TVs are HDR compatible, but that"s not the entire story. Just because a TV claims HDR compatibility doesn"t mean it can accurately display HDR content. All OLED TVs have the dynamic range to take advantage of HDR, but lower-priced LCDs, especially those without local-dimming backlights, do not. So if you want to see HDR content it all its dynamic, vibrant beauty, go for OLED or an LCD with local dimming.

In our tests comparing the best new OLED and LCD TVs with HDR games and movies, OLED usually looks better. Its superior contrast and lack of blooming win the day despite LCD"s brightness advantage. In other words LCD TVs can get brighter, especially in full-screen bright scenes and HDR highlights, but none of them can control that illumination as precisely as an OLED TV.

OLED"s energy consumption is directly related to screen brightness. The brighter the screen, the more power it draws. It even varies with content. A dark movie will require less power than a hockey game or ski competition.

The energy consumption of LCD varies depending on the backlight setting. The lower the backlight, the lower the power consumption. A basic LED LCD with its backlight set low will draw less power than OLED.

LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable.

Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured). Probably not, but then, why would you want it to? A 42-inch flat panel cost $14,000 in the late 90"s, and now a 65-inch TV with more than 16x the resolution and a million times better contrast ratio costs $1,400. Which is to say, by the time you"ll want/need to replace it, there will be something even better than what"s available now, for less money.

OLED TVs are available in sizes from 48 to 88 inches, but LCD TVs come in smaller and larger sizes than that -- with many more choices in between -- so LCD wins. At the high end of the size scale, however, the biggest "TVs" don"t use either technology.

If you want something even brighter, and don"t mind spending a literal fortune to get it, Samsung, Sony, and LG all sell direct-view LED displays. In most cases these are

You can get 4K resolution, 50-inch LCDs for around $400 -- or half that on sale. It"s going to be a long time before OLEDs are that price, but they have come down considerably.

LCD dominates the market because it"s cheap to manufacture and delivers good enough picture quality for just about everybody. But according to reviews at CNET and elsewhere, OLED wins for overall picture quality, largely due to the incredible contrast ratio. The price difference isn"t as severe as it used to be, and in the mid- to high-end of the market, there are lots of options.

The VR Display we provide includes 2.1 inch, 2.54 inch, 2.9 inch, 2.95 inch, 3 inch, 3.5 inch, 3.81 inch, 5.55 inch, 6 inch. For micro OLED can be used on VR, we provide 0.71 inch 1920x1080 display.

When you are choosing a VR, its parameters are important. First is resolution, then screen type, refresh rate, FOV, PPI, PPD, pupil distance adjustment, weight, etc. I believe most of you know the Arpara 5K VR reaches 5120*2560 resolution, so we won"t go deep into resolution today. But focus on display type. Is a VR hamlet good or bad, in fact, the impact of the screen is very big.

A lot of people might be thinking, what"s the impact of the screen? It"s actually quite important. You"ll understand after you read this article. Today, let"s dig deeper into some of the "secrets" of VR displays.

Now LCD is the most common VR device screen on the market, and a few VR products use OLED screens and Mirco-OLED screens. Micro OLED is unfamiliar for VR players. Arpara 5K PC VR, the world"s first VR device, is using the micro-OLED display.

At present, the VR hamlet mostly uses "TFT-LCD" (thin film transistor liquid crystal display) technology, which consists of two glass substrates sandwiched with a layer of liquid crystal, the upper glass substrate is a color filter, and the lower glass layer is embedded with the transistor, When the electric field generated by the current passing through the transistor changes, the original rotating arrangement of the liquid crystal molecules will be reversed, which will change the rotation amplitude of the light through, and shine on the color filter in different proportions, and then generate different colors.

LCD technology has been quite mature, used in general computer and TV screens, also used in VR screens, and the cost is low, has become the basic technology of consumer products.

At present, the most fatal problem of LCD is that the liquid crystal layer can not be completely closed, so if the LCD shows black, some light will pass through the color layer, so the black of LCD is actually a gray mixture of white and black, compared to pure black.

OLED(Organic Light-emitting Diode), is based on an Organic light-emitting layer made of indium tin oxide (ITO) glass and covered with a low-work function metal electrode on the light-emitting layer. According to the driving mode, OLED includes AMOLED and PMOLED.

Driven by the external voltage, the positive and cathode electrons will combine in the luminescent layer, generate energy and emit light, and generate Red, Green, and Blue primary colors due to different material characteristics to form the basic colors.

We know that the color of the screen is displayed by pixels, and it takes time for pixels to change from color 1 to color 2. This time is called grayscale response time.

If the gray-scale response time is too long, the pixel in images fast sliding too late that resulting from the color 1 to 2 in the picture, will appear on the vision ghosting, ghosting extremely influence visual perception, the OLED screen is almost without any delay, and the LCD screen, even if it is apple"s top LCD, have a longer response time.

OLED is not the same as LCD screens with black color. Because OLED displays black, the pixels in the black area can be turned off directly to achieve an almost pure black effect. In contrast, OLEDs have excellent contrast and lower power consumption.

To sum up OLED color characters in one sentence: OLED is an oil painting, with pure and delicate colors, while LCD is a watercolor painting, with hazy and light colors. I think people can tell the difference between a high-end OLED and an LCD at a glance.

Although OLED presents a bright picture, has low power consumption, and can be bent, the organic materials will be oxidized, so the life is relatively short, and the color-burning problem does occur. Coupled with the high cost and high technology content, it is mostly suitable for small screens, such as mobile phone screens. In recent years, a handful of VR helmets have used OLED screens.

Mrico-Oled is a new high-level microdisplay technology. Micro OLEDs (silicon-based) consist of organic light-emitting materials sandwiched between two electrodes, diodes that emit light when an electric current flows through them. The desired color is then generated through the filter. The micro OLED light source module is generated by depositing the OLED onto the substrate using vapor deposition.

For example, to produce silicon-based OLED modules, OLED is deposited onto a silicon substrate or semiconductor wafer. In addition to being self-luminous like OLED, micro-OLED help makes thinner, smaller, and more energy-efficient panels. Their shorter response times and higher luminous efficiency also enable the production of high PPI(pixels per inch) displays.

Micro OLED microdisplay devices have the advantages of OLED self-lighting, thin, light, large viewing Angle, short response time, and high luminescence efficiency. Moreover, it is easier to achieve the application effect of high PPI (pixel density), small size, easy to carry, and low power consumption, which is especially suitable for near-eye display devices.

Although VR products on the market have been developed for many years, due to immature technology, they are prone to dizziness, have low resolution, are large in size, expensive. To avoid vertigo, the screen resolution had to be raised from 500 PPI to 2,000 PPI. Micro-OLEDs meet the needs of VR headsets and lenses. Therefore, after years of polishing, Arpara chose to launch the world"s first VR device based on micro-OLED display technology - Arpara 5K PC VR.

As we said earlier, micro-OLED uses pixel self-lighting technology to easily achieve a wide range of colors. For example, our Arpara 5K VR with Mirco-OLED screen covers 90% of the DCI-P3 range, which is the standard for evaluating display capabilities in the film industry. It can reflect the color expression of the product when watching film and television content.

The following figure shows the corresponding color space of the Arpara 5K VR screen, which is highly identical to the DCI-P3 standard color space. The area ratio reaches 94% DCI-P3, and the coverage reaches 90%.

Pixels are small, individually lit elements that are emitted in an array to create a display. For various reasons, pixels sometimes have difficulty packing tightly together, and this causes the gaps between them to not light up. The "fill factor" of the display describes the ratio of the actual lit area to the unlit area. On a display with a low fill coefficient, the user is easy to perceive the dark space between pixels, which leads to the screen effect.

To reduce the screen effect, the filling coefficient should be increased, and at the same time, the pixel density should be increased to minimize the absolute value of the gap between pixels.

Let"s go back and mention the comparison of the previous three screens. For LCD screen, there is a high density of LCD display, but because the LCD display device is a transparent type, its pixel driving circuit can only be placed in a pixel gap, this leads to a certain gap between pixels to place the drive circuit, so even if the high-resolution LCD screen, also cannot avoid the Screen Door Effect. The picture below is an example of a square RGB arrangement of LCD pixels, in which the black part is the driving circuit part (the picture is a schematic, in fact, we need to make a better look, please forgive me)

Relatively speaking, because the OLED material is a self-emitting device, the driver circuit can be placed on the underlying substrate, so there is no dark spot of the driver circuit between pixels.

For large-size OLED screens such as AMOLED, the current fill coefficient is still low, so there are blank areas between the screen pixels, as shown below:

The Micro OLED technology selected by Arpara can well control the pixel gap and greatly increase the pixel filling ratio. The schematic diagram is as follows:

Then again, micro-OLED has a big advantage in the small display market. As the applications of VR and AR displays gradually shift from gaming and military fields to healthcare, education, retail, and other fields, the market continues to expand, and more and more consumers demands resolution and avoidance of display lag. In this case, researchers will start to develop a new generation of display technology with high resolution, high brightness, high contrast, and fast response. At present, micro-OLED is most widely used in military, industrial and medical fields. VR is likely to be the next big thing.

OLED is the display technology that has everyone talking. Considering the inky shadows, vivid highlights, and lifelike colors that these panels can produce, it’s no wonder. For 2022, we’re offering this coveted display tech across a wide range of our ProArt Studiobook, Zenbook, and Vivobook families of laptops. From our affordable everyday laptops to our premium, luxury machines, you’ll find an OLED-equipped laptop that fits your needs and budget. So what sets these displays apart from the competition? Here, we’ll break down the LCD vs. OLED debate so that you can pick the best laptop for your needs.

If you bought a high-end smartphone in recent years, you likely already have an example of this premium panel tech ready to hand. Ever wonder why photos and videos seem to look better on your phone than your old laptop? That could be because OLED displays excel at producing lifelike images with vibrant colors and striking contrast.

Both LCD and OLED displays create the image on your screen using millions of individual pixels. However, on standard LCDs, those pixels are illuminated by an always-on backlight, usually an array of large LEDs, that light up the entire screen at once. It’s an efficient arrangement, but it hinders a display’s ability to produce inky shadows, since the black pixels still have some light behind them. On an OLED display, however, there is no backlight—instead, each pixel acts as its own light source, and can be turned on or off independently of the others. This means that black portions of an image can be truly black, because there’s no light source shining through behind them.

OLED panels also excel at displaying vibrant, lifelike colors. Typically, they offer wide color gamut coverage comparable with the color production of expensive studio-grade monitors. Between the intense colors, inky shadows, and striking highlights, OLED panels deliver an image that leaps off the screen. For media of all kinds, you’ll see the difference right away.

For folks who often use their laptops in well-lit rooms full of natural light, a display with a high peak brightness is crucial. Our Vivobook Pro 16X OLED, for example, offers a 550-nit peak brightness so that you can comfortably use the laptop wherever, whenever.

But a display’s low-light performance matters, too. You probably turn down the brightness when you’re in a dimly lit bedroom to conserve battery life—and so it doesn’t sear your eyes when you open a website with a white background. Unfortunately for LCD displays, their contrast and color production often suffer at low brightness levels, leading to a washed-out image where it’s hard to distinguish one color from another. An LCD might only cover 11% of the DCI-P3 color gamut at its lowest brightness setting. To make matters worse, many LCDs introduce distracting, annoying flicker at low brightness levels due to their use of pulse-width modulation (PWM) techniques.

OLED panels, on the other hand, shine in this scenario. Much more than LCDs, they can deliver the vibrant colors and striking contrast that makes your content immersive and text easy to read. ASUS OLED panels maintain 100% DCI-P3 color gamut coverage at both high and low brightness levels, giving you accurate, lifelike colors across the board. Our OLED panels are certified for flicker-free performance by TÜV Rheinland, too. For comfortable use in a wide range of scenarios, OLED panels are the way to go.

When many of us think about using our laptop, we imagine ourselves sitting directly in front of the screen. While this is how folks commonly use a laptop, it’s not the entire story. You’ve probably watched a movie on your laptop with a loved one, collaborated with a classmate on a project, or followed an online recipe as you cooked dinner. Look at an LCD display from a sharp angle, as you likely had to do in any of these instances, and you’ll often see an ugly, color-shifted image.

This is another circumstance where OLED panels stand out from the other options. While some types of LEDs, notably IPS panels, offer wide viewing angles, OLED displays tend to offer wider viewing angles than even the best LEDs. With an OLED-equipped laptop, you’ll always have a clear view of the screen, even in those regular moments when you’re not looking at it straight-on.

An LCD display has a single, always-on backlight that emits broad-spectrum white light similar to what you see during the daytime. That’s fine during typical working hours, but prolonged exposure to blue wavelengths in the evening hours can disrupt your circadian rhythm and make it harder for you to fall asleep.* That’s why we offer a range of Eye Care monitors that give you tools for reducing your exposure to blue light.

Another option is an OLED display. Since each pixel in an OLED panel is its own light source, these displays automatically emit less blue light than LCD options under almost all conditions—about 70% less, compared with standard LCD displays.** You’ll be much more able to browse your TikTok feed or catch a show before bedtime without throwing off your sleep schedule. And your eyes will get fatigued more slowly when you use your PC, making you better able to finish a creative project while you’re still feeling the inspiration.

Netflix, Amazon Prime Video, and Disney Plus all let you stream movies and shows in High Dynamic Range, or HDR. An increasing number of games let you play in HDR, too. No matter what kind of content you enjoy, odds are you’ll want your next laptop to enjoy the inky shadows, dazzling highlights, and wide color gamut coverage of the next generation of media.

There are LCD displays that deliver a credible HDR experience, but OLED displays are a more natural fit for the content. The infinite contrast of an OLED display lets you have a brightly shining pixel right next to a perfectly black one, perfect for displaying high-contrast scenes. Bright stars in the infinite blackness of space, fireworks bursting across a night sky, and the sun setting behind a natural landscape never looked so good as they do on an OLED display. Look for laptops with Dolby Vision support and a VESA DisplayHDR 400 True Black or DisplayHDR 500 True Black certification to ensure the best experience.

That said, you certainly can get an LCD display that’s primed and ready for HDR. Our ROG Zephyrus Duo 16 includes a display option with a full-array local-dimming (FALD) backlight comprising 512 Mini LEDs that approximate the contrast ratio that an OLED panel can achieve. On top of that, it offers an 1100-nit peak brightness and a VESA DisplayHDR 1000 certification. That increased high-end luminance means that you can see more detail in bright images than you would on an HDR display with lower peak brightness.

When you’re watching an action movie, cheering on your favorite athletes during March Madness, playing a round of Fortnite with your friends, or simply tracking the movement of your mouse cursor across the screen as you get some work done, the clarity of moving objects on your display matters. The key spec here is response time. Each pixel on any display takes a small but noticeable amount of time to transition from one color to the next. On a display with poor response time, this appears as a distracting blur that resolves and goes away when the image stops moving. Our OLED panels offer an exceptional 0.2ms response time that gives you absolute clarity in moving images. Comparable LCD displays can take up to 10ms to switch colors.

It’s not just the sharpness of any given image that’s improved by low response time. The accuracy of any given pixel is affected, as well. A typical 60Hz panel refreshes the content on the screen every 16.67 milliseconds. If a pixel takes 10ms to transition to the correct color, then it only actually spends 6.67ms displaying the correct color. A pixel that only needs 0.2ms to transition to the correct color displays that color for almost the entirety of the refresh cycle. Whether you’re watching an action-packed movie, cheering on your favorite sports team, or digging into a great nature documentary, you’ll see a clear image throughout instead of blurry motion.

However, not all LCD displays are built the same. Purchase a gaming laptop equipped with one of our ROG Nebula Displays, and you’ll enjoy a speedy 3ms response time. What’s more, LCD panels are capable of reaching refresh rates that OLED can’t currently match. Our ROG Strix SCAR laptops, for example, can be equipped with a lightning-quick 360Hz display. If you’re shopping for a laptop primarily for fast-paced competitive gaming, a high-refresh-rate LCD display is likely a better fit for you.

As you read articles about OLED displays and watch reviews on YouTube, you might notice people talking about “burn-in.” More accurately known as image retention, this is a type of image distortion that can occur when users display static images or on-screen elements at peak brightness levels uninterrupted for many hours, if not days, at a time. Most folks simply don’t use their monitors in this way, so in real-world usage, you can purchase a laptop with an OLED display with the confidence that you’re unlikely to encounter image retention issues. For additional peace of mind, check out the results of a long-term uniformity test conducted by a trusted independent media outlet.

To provide an additional layer of protection against image retention, we include a suite of ASUS OLED Care settings in the easy-to-use MyASUS app. Pixel refresh launches a special screen saver when your display has been idle for 30 minutes that refreshes your screen pixels and optimizes picture quality. Pixel shift moves display pixels almost invisibly to help make sure that static images aren’t constantly displayed on your desktop. And we make it easy to adjust your Windows taskbar settings so that this static display element doesn’t cause any long-term image retention issues.

Some best practices can give you even more assurance that your OLED display will deliver a pristine image over the expected lifetime of the device—and they’re things that you’d likely already do with your laptop anyway. It’s prudent to have the display turn off due to inactivity after a certain amount of time. Rather than leave the brightness level at maximum constantly, it’s a good idea to dial back the display brightness to best fit the surrounding ambient light. Both of these prudent measures help extend battery life, as well, so you likely do these things with your laptops anyway. Finally, our OLED-equipped laptops ship with Dark Mode enabled in Windows by default so that static UI elements aren’t unnecessarily bright.

For most users, an OLED panel is a better fit than an LCD panel. The infinite contrast these displays provide make them more comfortable to use in a wide range of applications. Whether you’re connecting with friends on social media, skimming through your email, watching the latest show, or just browsing your favorite sites, an OLED panel will elevate your experience. Ultra-wide viewing angles let you share any of these things wit
