When it comes todisplay technologies such asprojectorsand panels, factors such as resolution and refresh rate are often discussed. But the underlying technology is equally, if not more, important. There are tons of different types of screens, from OLED and LED to TN, VA, and IPS. Learn about the various monitor and television types, from operation to pros and cons!

The most common form of monitor or TV on the market is LCD or Liquid Crystal Display. As the name suggests, LCDs use liquid crystals that alter the light to generate a specific colour. So some form of backlighting is necessary. Often, it’s LED lighting. But there are multiple forms of backlighting.

LCDs have utilized CCFLs or cold cathode fluorescent lamps. An LCD panel lit with CCFL backlighting benefits from extremely uniform illumination for a pretty even level of brightness across the entire screen. However, this comes at the expense of picture quality. Unlike an LED TV, cold cathode fluorescent lamp LCD monitors lack dimming capabilities. Since the brightness level is even throughout the entire array, a darker portion of scenes might look overly lit or washed out. While that might not be as obvious in a room filled with ambient light, under ideal movie-watching conditions, or in a dark room, it’s noticeable. LED TVs have mostly replaced CCFL.

An LCD panel is transmissive rather than emissive. Composition depends on the specific form of LCD being used, but generally, pixels are made up of subpixel layers that comprise the RGB (red-green-blue) colour spectrum and control the light that passes through. A backlight is needed, and it’s usually LED for modern monitors.

While many newer TVs and monitors are marketed as LED TVs, it’s sort of the same as an LCD TV. Whereas LCD refers to a display type, LED points to the backlighting in liquid crystal display instead. As such, LED TV is a subset of LCD. Rather than CCFLs, LEDs are light-emitting diodes or semiconductor light sources which generate light when a current passes through.

LED TVs boast several different benefits. Physically, LED television tends to be slimmer than CCFL-based LCD panels, and viewing angles are generally better than on non-LED LCD monitors. So if you’re at an angle, the picture remains relatively clear nonetheless. LEDs are also extremely long-lasting as well as more energy-efficient. As such, you can expect a lengthy lifespan and low power draw. Chances are you’ll upgrade to a new telly, or an internal part will go out far before any LEDs cease functioning.

Further segmenting LED TVs down, you’ll find TN panels. A TN display or Twisted Nematic display offers a low-cost solution with low response time and low input lag. TN monitors sport high refresh rates, so 100Hz, 144Hz, or higher. Thus, many monitors marketed toward gamers feature TN technology. Unfortunately, while an affordable, fast panel may sound ideal, TN panels suffer from inferior colour reproduction and horrible viewing angles. A TN panel works so that liquid crystal molecules point at the viewer, and light polarizers are oriented at 90-degree angles.

Like TN, IPS or In-plane Switching displays are a subset of LED panels. IPS monitors tend to boast accurate colour reproduction and great viewing angles. Price is higher than on TN monitors, but in-plane switching TVs generally feature a better picture when compared with twisted nematic sets. Latency and response time can be higher on IPS monitors meaning not all are ideal for gaming.

A VA or vertical alignment monitor features excellent contrast ratios, colour reproduction, and viewing angles. It’s a type of LED monitor with crystals perpendicular to the polarizers at right angles like TN monitors. Pricing varies, but response time isn’t as high as a TN monitor.

A quantum dot LED TV or QLED is yet another form of LED television. But it’s drastically different from other LED variants. Whereas most LED panels use a white backlight, quantum dot televisions opt for blue lights. In front of these blue LEDs sits a thin layer of quantum dots. These quantum dots in a screen glow at specific wavelengths of colour, either red, green, or blue, therefore comprising the entire RGB (red-green-blue) colour spectrum required to create a colour TV image.

QLED TV sets are thus able to achieve many more local dimming zones than other LED TVs. As opposed to uniform backlighting, local dimming zones can vary backlighting into zones for adjustable lighting to show accurate light and dark scenes. Quantum Dot displays maintain an excellent, bright image with precise colour reproduction.

An OLED or organic light-emitting diode display isn’t another variation of LED. OLEDs use negatively and positively charged ions for illuminating individual pixels. By contrast, LCD/LED TVs use a backlight that can make an unwanted glow. In OLED display, there are several layers, including a substrate, anode, hole injection layer, hole transport layer, an emissive layer, blocking layer, electron transport layer, and cathode. The emissive layer comprised of an electroluminescent layer of film is nestled between an electron-injecting cathode and an electron removal layer, the anode. OLEDs benefit from darker blacks and eschew any unwanted screen glow. Because OLED panels are made up of millions of individual subpixels, the pixels themselves emit light, and it’s, therefore, an emissive display as opposed to a transmissive technology like LCD/LED panels where a backlight is required behind the pixels themselves.

Image quality is top-notch. OLED TVs feature superb local dimming capabilities. The contrast ratio is unrivalled, even by the best of QLEDs, since pixels not used may be turned off. There’s no light bleed, black levels are incredible, excellent screen uniformity, and viewing angles don’t degrade the picture. Unfortunately, this comes at a cost. OLEDs are pricey, and the image isn’t as bright overall when compared to LED panels. For viewing in a darkened room, that’s fine, but ambient lighting isn’t ideal for OLED use.

What is an OLED:Organic light-emitting diode display, non-LED. Emissive technology is where negatively and positively charged ions illuminate individual pixels in a display.

As you can see, there are tons of different types of displays, each with their advantages and disadvantages. Although many monitors and TVs are referred to by different names like LED, IPS, VA, TN, or QLED, many are variations of LCD panels. However, specific technology such as the colour of backlighting and alignment of pixels dictates the picture quality. OLED is an entirely different form of display that’s not LED. Now that you understand the various types of monitors and televisions on the market, you can select the best TV to fit your needs!

An LED stands for light-emitting diodes. It is among the latest in technological innovations related to screening display. It makes use of LEDs behind the screen as the source of light. LEDs are brighter and more energy-efficient than an LCD screen that uses a CCFL backlight. They are also a lot smaller that helps in producing thinner screens like never before. Since LEDs are very bright so the display doesn’t get marred even in broad daylight. That is the reason LEDs are extensively used in signboards and advertising boards throughout the world. Let’s take a deeper look at this technology here and get to know it better.

Outdoor LED displays are used for advertising, promotion, and informative purposes. You can install them easily almost anywhere and they will do their job effectively. You can use them 24/7. They consume less electricity, have a long life, low-maintenance and are eco-friendly. They are available in a variety of sizes and you can also make one according to your custom needs. You can make one giant billboard, signboards, advertising banners, LED boards, LED video walls, perimeter LED boards, with the help of LED screens.

The outdoor LED display market is poised to grow at a robust speed. It is estimated to be worth around US$22.4 billion by the year 2024. That’s a CAGR of over 20% from 2016-2024.

Many factors are fueling this growth. For starters, companies prefer to advertise their brands and products through LED displays, smart billboards with wireless connectivity and easily changeable content are a rage nowadays. Similarly, 3D technology is being employed in LED displays for a more immersive and personal viewing experience. Motion sensor technology and interactive displays are also making their mark. The demand for high resolution displays for showcasing anything like advertising in perimeter boards in a stadium, musical concert, traffic updates on roads, live sporting events, exhibitions will contribute to the growth of the LED display sector. The continuous technological advancements in this sector will mean crisper, clearer, and livelier displays in the future. So, just like the display LEDs, the future is very bright for this sector.

Despite all its success and potential growth, the LED display market is not without its share of challenges. Here, we briefly discuss some of the more important ones.

Unstable supply of raw materials: An LED screen is made of several electronic components. It is difficult to produce all of them in the same country. When you have to import from other countries difficulties arise. From ensuring fair quality to optimum quality to coping with fluctuation in forex rates to import tariffs. All these factors combine to make the procurement of raw materials difficult to manage.

Capital: LED manufacturing involves huge capital. It is not always to raise one on your own. If you go to a bank, it will imply interest payments. This will affect your cash flows and profit margins.

Technological innovation: LED manufacturing is technologically intensive. There is a race going on to beat your competitor at the cutting edge of technology. As a manufacturer, it will be a challenge for you to keep up with all the new changes. It might involve the injection of new funds or training the old staff or hiring a new one.

Logistics: Transporting LEDs from one place to another involves a great deal of caution. They have to be securely packed to withstand shocks and jerks. Even a crack can ruin the entire screen, what to talk of a broken one.

Rules of import: As an importer of LEDs you have to comply with the local import laws. This includes getting an import permit, paying import duties, transportation cost, and custom clearing charges. Sometimes a slight change in rules can throw your estimates out of the window.

Low profits: There is stiff competition going on among the LED manufacturers. While this is good news for the consumer the producer may suffer because of low-profit margins. This precludes entry of new players and leads to grouping.

Expensive labor: You require skilled and competent labor to produce LEDs and they come at a price. This is particularly problematic as the margins of profit continue to squeeze.

Ideal location: Everybody wants the best placement of its LED screens for promotional purposes. The best spots are few and far between. This results in a rising price of prime locations and unhealthy competition among the brands to get the best spot.

Rental screens: The rental LED screens face a lot of wear and tear because they change locations and this consequently reduces their life and performance.

The most important use of LED displays is for advertisement purposes. This includes billboards, banners, perimeter boards, boards, signboards, etc. They can be installed at various locations of choice.

It is the same as outdoor advertising with the only difference that their location is not permanent. They can be installed and uninstalled at various locations as per requirement.

Transparent LED display is an innovation of recent times. It lets viewers see things behind the screen as well. This has become possible due to the material, structure, and design of the display screen. It is not 100% transparent, the transparent rate is around 50-95%. The thickness is around 10mm. It is just like a glass.

LEDs have become quite popular for stage productions. People in the back seats can now see the action on stage thanks to these screens. They are usually large and very bright to produce a visible image. They are used in entertainment events and art exhibitions.

Like entertainment events, LEDs have become very popular to broadcast sporting events too. They are installed inside and out of the sporting arenas to bring spectators closer to the game. Their installation has helped rekindle the interest in live sporting events.

Outdoor digital displays are used for a variety of purposes. They can be installed on roads to provide traffic updates, in airports and railway stations to give information about trains and airplanes’ schedule and in sports to display scorecard. The uses are multiple and varied and you can use it for your advantage.

What is life without colors? From the time first black and white image surfaced man had been striving to convert it to colors. Once that was accomplished, the race is on to bring colors as close to real-life as possible. LEDs are no exception. They take pride in reproducing colors on screen as close to nature as possible. They look attractive and capture your attention.

In a quest for excellence, the color display went from better to best and the journey is ongoing. HD display is one such example. HD, of course, stands for high definition. HD has a resolution of 1280×720 pixels. Full HD has a resolution of 1920×1080 pixels. It doesn’t stop here and goes further to UHD, OLED, etc. These are especially helpful where you have to showcase products like jewelry, clothes, etc.

Eye-catching: The first and foremost is that the LED advertising screens are attention-grabbing. Their crisp, colorful and sharp images are very appealing. You are instantly drawn towards them.

Eco-friendly: Unlike flex, paper, or clothing banners there aren’t any harmful chemicals used in producing LEDs. You also save a lot of trees because LEDs don’t require organic elements for production.

Energy-efficient: LEDs consume very low voltage and they produce very striking results. This saves electricity. You get a very bright image at a very cost.

Low-maintenance: LED screens are almost maintenance-free and can withstand weather adversaries too. You will see them displaying their imagery in the rain and intense sunlight.

Changing content: You can change the content of an LED advertising screen quite easily. This means you can run multiple campaigns of the same brand simultaneously. This gives variety to the viewer and he doesn’t feel bored with seeing the same campaign again and again.

Flexibility: It is very easy to change the content of the LED screen as well as to change the location of the screen. You can do so either with very little effort. It allows you great freedom to play with it.

P10 and P6 are both LED screen types. The pixel pitch of P10’s display is 10mm and for P6 it is 6mm. They are both very popular when it comes to outdoor advertising. We list down some of the reasons why;

On a single or double poles: This is a simple installation where LED is installed on single or two columns for displays. A single column is used for a small screen size while the double column is used for a larger screen.

Hanging: You can also hang a LED both inside and outside depending on your need. The panel of the LED should be made for hanging purpose and the LED should itself be lightweight. The wind factor must be taken into consideration before installation.

Embedded type: An LED can also be embedded in a wall. You need to be mindful that you won’t be able to perform any maintenance from behind the LED once it is embedded into the wall.

Mounted type: Another option is that you mount the LED on the wall. In this way, you can do maintenance work on the behind of the LED. It is a very common type of LED installation.

There are trade fairs taking place all over the year in China. Some fairs are general while others are industry-specific. You can choose either and pay a visit. Usually, industry-specific fairs are more beneficial as manufacturers prefer to go there.

As for hunting LED factories online, the most popular resource is Alibaba.com. Then there is made-in-china.com. Globalresources.com is also a good option. They are easy to use and reliable e-commerce sites. You will have to register yourself before contacting any supplier/manufacturer. While some suppliers are verified and the websites vouch for their quality, for others you will have to guard yourself against fraud and wrongdoing.

A: Unless you are technically sound and know the electronic component of the LEDs do not attempt any repair on your own. Hire a technician who will find the cause and repair it. You can try to ascertain the cause of the problem and attempt re-booting. Sometimes the problem is resolved by mere re-booting.

A: No, it won’t. Cold, hot, or harsh climate won’t affect the working of the LED lights. They are manufactured keeping in view the hostilities of weather. This adds to their durability and is one of the reasons for their widespread use and popularity.

Market research firm Sigmaintell said BOE Technology Group Co Ltd－a leading Chinese supplier of display products and solutions－became the world"s largest shipper of LCD TV panels for the first time in 2019.

The Beijing-based company shipped 53.3 million units of LCD panels in 2019, with production capacity increasing by more than 20 percent on a yearly basis.

The consultancy said the LCD TV panel production area of Chinese manufacturers will account for more than 50 percent of the global total this year, surpassing South Korean competitors who are accelerating the shutdown of large-sized LCD panel production capacity due to competition from Chinese manufacturers.

It estimated the production capacity of large-sized LCD panels will continue to increase in China over the next three years. In addition, global LCD TV panel shipments stood at 283 million pieces last year, a slight decrease of 0.2 percent year-on-year. Meanwhile, the shipment area was 160 million square meters, an increase of 6.3 percent year-on-year.

"Chinese companies have gained an upper hand in large-screen LCD displays. Samsung and LG"s decision to exit from the LCD sector means Chinese panel makers will take a dominant position in this field," said Li Dongsheng, founder and chairman of Chinese tech giant TCL Technology Group Corp.

Li said South Korean firms will focus on organic LED screens and quantum dot LED displays, while Chinese TV panel makers are catching up at a rapid pace.

Data consultancy Digitimes Research said it comes as little surprise that Samsung has opted to withdraw from the LCD panel sector as its LCD business was losing money in every quarter of 2019 due to challenges from Chinese competitors.

BOE said its Gen 10.5 TFTLCD production line achieved mass production in Hefei, Anhui province, in March 2018. The plant mainly produces high-definition LCD screens of 65 inches and above. With a total investment of 46 billion yuan ($6.5 billion), the company"s second Gen 10.5 TFT-LCD production line launched operations in Wuhan, Hubei province, in December.

The Gen 11 TFT-LCD and active-matrix OLED production line of Shenzhen China Star Optoelectronics Technology, a subsidiary of TCL, officially entered operations in November 2018, producing 43-inch, 65-inch and 75-inch LCD screens.

Bian said the OLED and QLED will be the next-generation flat-panel display technologies to be in the spotlight. LG Display is currently the world"s only supplier of large-screen OLED TV panels.

OLED is a relatively new technology and part of recent display innovation. It has a fast response rate, wide viewing angles, super high-contrast images and richer colors. It is much thinner and can be made flexible, compared with traditional LCD display panels.

Li Yaqin, general manager of Sigmaintell, said 65-inch TVs will become the mainstream in people"s living rooms in the future, but OLED TVs will not be able to immediately spur customer purchases at this time though the future trend is for higher-tech options.

It seems as if modern displays have all kinds of different labels: high definition, 3D, smart, 4K, 4K Ultra, the list goes on. The two most common labels are LCD and LED. What’s the difference between the two? Is there a difference? And does this difference make one or the other preferable for certain types of activities like gaming or graphic design?

All LED monitors are LCD monitors. But not all LCD monitors are LEDs. Kind of like all eagles are birds, but not all birds are eagles. While the names might be confusing to those wading through specs to find the best monitor, once you break it down it’s easier to understand than you think.

We’ll explain the tech and the naming conventions, and then highlight some HP monitors that might be the perfect fit for your needs. Let’s figure out exactly what LCD and LED monitors are and how to pick the right one for you.

Both types of displays use liquid crystals to help create an image. The difference is in the backlights. While a standard LCD monitor uses fluorescent backlights, an LED monitor uses light-emitting diodes for backlights. LED monitors usually have superior picture quality, but they come in varying backlight configurations. And some backlight configurations create better images than others.

Until 2014, plasma displays were the most commonly manufactured displays. But then the LCD took over. LCD stands for liquid crystal display. We’ll go over what that means in a minute. But first, it’s important to note that an LED also uses liquid crystals, so the name is somewhat misleading. Technically, an “LED monitor” should really go by the name, “LED LCD monitor.”

First, let’s go over how LCD and LED monitors utilize liquid crystals. The science behind this stuff features an incredibly complicated mix of optics, electrical engineering, and chemistry. But we’ll explain it in layman’s terms.

LCD monitors have backlights behind the screen that emit white light, and the light can’t pass through the liquid crystals while they’re in their liquid arrangement. But when the pixel is in use, the monitor applies an electric current to the liquid crystals, which then straighten out and allow light to pass through them[2].

Standard LCD monitors employ “cold cathode fluorescent lamps,” also known as CCFLs as backlights. These fluorescent lights are evenly placed behind the screen so that they deliver consistent lighting across the display. All regions of the picture will have similar brightness levels.

LED monitors don’t use fluorescent lamps. Instead, they use “light-emitting diodes,” which are extremely small lights. There are two methods of LED backlighting: full-array backlighting and edge lighting.

With full-array backlighting, the LEDs are placed evenly across the entire screen, similar to an LCD setup. But what’s different is that the LEDs are arranged in zones. Each zone of LED lights can be dimmed (also known as local dimming).

When there’s an area of the picture that needs to be darker (a night sky, for instance), the LEDs in that region of the picture can be dimmed to create a truer black. This is not possible on standard LCD monitors, where the entire picture is lit evenly throughout.

There are no local dimming capabilities in edge-lighted displays, so they can’t create pictures that are as high-quality as those created by full-array LEDs. However, edge lighting enables manufacturers to create extremely thin displays that don’t cost as much to produce - and which are better for a tight budget.

When it comes to picture quality, full-array LED monitors are almost always superior to LCD monitors. But bear in mind that only full-array LEDs are superior. Edge-lit LEDs may actually be inferior to LCD monitors.

A full-array LED monitor should be your number one choice for gaming. Steer clear if its edge lighting. The problem with edge lighting is that you’ll have fewer optimal viewing angles with which to play games. That’s not an issue if you prefer to sit directly in front of the screen while you’re gaming. But if you like to kick back in your chair or view from different angles, you’ll find that an edge-lit LED loses visibility as you move away from the center viewing angle.

But even if you play while you’re directly in front of the monitor, edge-lit LEDs have more issues with glare than full-array LEDs do. That’s because of the uneven lighting (very bright around the edges, darker as you approach the center of the display). Because the pixels are evenly lit, LCD monitors tend to have better viewing angles and anti-glare than edge-lit LEDs.

Edge-lit LEDs do have two big advantages. If you have a very tight space in which to fit your monitor, you’ll like having an edge-lit LED because they’re usually thinner than the other types. They’re also less expensive to manufacture, which make them easier on the wallet.

Resolution refers to how many pixels are displayed on the monitor. Remember, the more pixels you have, the more dynamic your composition of colors can be. The highest-quality monitors have resolutions of at least 1920 x 1080.

Because LED monitors create better pictures than LCD monitors, nearly all of HP’s displays are built with LED backlights. When you’re browsing through the HP LED monitors, you might notice that some of them are equipped with either “IPS” or “AHVA” technology. These refer to the types of liquid crystal panels that are used. Both are fantastic, although they have some minor differences:

You’ll also see that some monitors have “TN” LED backlights. This is the oldest form of liquid crystal technology. It’s still very effective, but TN panels are typically used in small, work-oriented monitors that are made to be mounted or used in the field.

HP OMEN gaming monitors are built for the power PC gamer. One of the best gaming monitors for your rig is the HP OMEN 32 32-inch display. This LED monitor has VA-type panels, which help give it a fast refresh rate that’s perfect for high-performance gaming.

If you’re a digital illustrator, video editor, photo editor, or special effects wiz, you should give the HP EliteDisplay S270n 27-inch 4K micro edge monitor a look. When you’re creating digital art, you need the most expansive resolution and highest-quality color production possible, and that’s what you’ll get with this IPS-equipped monitor. The micro edge screen makes it easy to use dual monitors, but the 27-inch screen alone gives you a wide interface to work on.

If you’re a business person, try one our HP EliteDisplay monitors, like the HP EliteDisplay E243 23.8-inch monitor. The IPS LED display is gorgeous and will give you a crisp and clear picture no matter what software you’re using. The micro edges make it perfect for a dual monitor setup, and the 23.8-inch size is wide, but not too large to accommodate a second monitor or to fit into tighter workstations.

There are some up-and-coming technologies that are making LED displays even better. OLED and QLED displays are bound to become more commonplace in the future.

“OLED” stands for “organic light-emitting diode.” What makes an OLED unique is that each pixel has a light source that can be individually shut off. On an LED monitor, the only way to keep a pixel from emitting light is to keep the liquid crystal closed. It’s effective, but not perfect - a small portion of light will always seep through. On an OLED monitor, each pixel’s light can be entirely shut off so no light at all will emanate through the liquid crystal. These means you can get truer blacks, which means deeper contrast ratios and better image quality.

There are two additional advantages. First, OLED monitors can be made even thinner than LED monitors because there’s not a separate layer of LEDs behind the pixels. Second, these monitors are more energy efficient because the pixels will only draw power when their light is turned on. One of the downsides, though, is that pixel burn-in will be more noticeable since some pixels will inevitably be used more than others[4].

“QLED” stands for “quantum light-emitting diode.” In a QLED monitor, each pixel has a “quantum dot.” Quantum dots are tiny phosphor particles that glow when you shine a light upon them[5].

Why would you need a glowing particle over each pixel? Because LEDs aren’t very good at emitting bright light. The brightest color is white. But an LED doesn’t emit white light – it emits blue light. Each LED is given a yellow phosphor coating to make it appear less blue and more white, but it’s still not true white. The “blueness” of LEDs negatively impacts the red, blue, and green colors on LED displays. LED monitors have automatic features that adjust the RGB colors to compensate for the blue light, but it can’t compensate for the weaker light intensity.

That’s where the quantum dots come in. The pixels are overlayed by a sheet of red and green quantum dots (there is no blue because blue light is already being emitted by the LED). When the light shines through the liquid crystals, the quantum dots glow, and you’re given a bright, vivid, and lovely spectrum of RGB colors.

Displays are a complicated science, right? But next time you’re shopping for monitors at the store or on our HP Store site, you’ll be a true expert and will be able to pick out exactly the right display for you.

TFT LCD is a mature technology. OLED is a relatively new display technology, being used in more and more applications. As for Micro LED, it is a new generation technology with very promising future. Followings are the pros and cons of each display technology.

TFT Liquid Crystal Display is widely used these days. Since LCD itself doesn"t emit light. TFT LCD relies on white LED backlight to show content. This is an explanation of how TFT LCD works.

Relatively lower contrast：Light needs to pass through LCD glasses, liquid crystal layer, polarizers and color filters. Over 90% is lost. Also, LCD can not display pure black.

Organic Light-Emitting Diode is built from an electro-luminescent layer that contains organic compounds, which emit light in response to an electric current. There are two types of OLED, Passive Matrix OLED (PMOLED) and Active Matrix OLED (AMOLED). These driving methods are similar to LCD"s. PMOLED is controlled sequentially using a matrix addressing scheme, m + n control signals are required to address a m x n display. AMOLED uses a TFT backplane that can switch individual pixels on and off.

Low power consumption and flexible: OLED doesn"t rely on backlight and consumes less power. OLED is essentially created on plastic film. It is bendable and easy to process.

High contrast and vivid color: OLED emits light itself, can produce very bright image with beautiful color. And because OLED can be turned off, it can produce true black.

Stroboscopic effect: most OLED screen uses PWM dimming technology. Some people who are easy perceive stroboscopic frequency may have sore eyes and tears.

Micro LED, sometimes called μLED is made up of tiny LED, measure less than 100μm. Another way of looking at this is that MicroLEDs are simply traditional LEDs shrunk down and placed into an array.

Replacing organic material with inorganic GaN material eliminates the need of polarizing and encapsulation layer, found in OLED. Micro LED is smaller and thinner, consumes less power.

If you’re designing a display application or deciding what type of TV to get, you’ll probably have to choose between an OLED or LCD as your display type.

LCDs utilize liquid crystals that produce an image when light is passed through the display. OLED displays generate images by applying electricity to organic materials inside the display.OLED and LCD Main Difference:

graphics and images visible. This is the reason you’re still able to see light coming through on images that are meant to be dark on an LCD monitor, display, or television.

OLEDs by comparison, deliver a drastically higher contrast by dynamically managing their individual pixels. When an image on an OLED display uses the color black, the pixel shuts off completely and renders a much higher contrast than that of LCDs.OLED vs LCD - Who is better at contrast?

Having a high brightness level is important if your display is going to be used in direct sunlight or somewhere with high ambient brightness. The display"s brightness level isn"t as important if it’s going to be used indoors or in a low light setting.OLED vs LCD - Who is better at Brightness?

This means the display is much thinner than LCD displays and their pixels are much closer to the surface of the display, giving them an inherently wider viewing angle.

You’ll often notice images becoming distorted or losing their colors when tilting an LCD or when you view it from different angles. However, many LCDs now include technology to compensate for this – specifically In-Plane Switching (IPS).

LCDs with IPS are significantly brighter than standard LCDs and offer viewing angles that are on-par with OLEDs.OLED vs LCD - Who is better at Viewing Angles?

LCDs have been on the market much longer than OLEDs, so there is more data to support their longevity. On average LCDs have proven to perform for around 60,000 hours (2,500) days of operation.

With most LCDs you can expect about 7 years of consistent performance. Some dimming of the backlight has been observed but it is not significant to the quality of the display.

OLEDs are a newer technology in the display market, which makes them harder to fully review. Not only does OLED technology continue to improve at a rapid pace, but there also hasn’t been enough time to thoroughly observe their performance.

You must also consider OLED’s vulnerability to image burn-in. The organic material in these displays can leave a permanent afterimage on the display if a static image is displayed for too long.

So depending on how your OLED is used, this can greatly affect its lifespan. An OLED being used to show static images for long periods of time will not have the same longevity as one displaying dynamic, constantly moving images.OLED vs LCD - Which one last longer?

There is not yet a clear winner when it comes to lifespans between LCD and OLED displays. Each have their advantages depending on their use-cases. It’s a tie!

For a display application requiring the best colors, contrast, and viewing angles – especially for small and lightweight wearable devices – we would suggest an OLED display.

Samsung Display will stop producing LCD panels by the end of the year. The display maker currently runs two LCD production lines in South Korea and two in China, according to Reuters. Samsung tells The Verge that the decision will accelerate the company’s move towards quantum dot displays, while ZDNetreports that its future quantum dot TVs will use OLED rather than LCD panels.

The decision comes as LCD panel prices are said to be falling worldwide. Last year, Nikkei reported that Chinese competitors are ramping up production of LCD screens, even as demand for TVs weakens globally. Samsung Display isn’t the only manufacturer to have closed down LCD production lines. LG Display announced it would be ending LCD production in South Korea by the end of the 2020 as well.

Last October Samsung Display announced a five-year 13.1 trillion won (around $10.7 billion) investment in quantum dot technology for its upcoming TVs, as it shifts production away from LCDs. However, Samsung’s existing quantum dot or QLED TVs still use LCD panels behind their quantum dot layer. Samsung is also working on developing self-emissive quantum-dot diodes, which would remove the need for a separate layer.

Samsung’s investment in OLED TVs has also been reported by The Elec. The company is no stranger to OLED technology for handhelds, but it exited the large OLED panel market half a decade ago, allowing rival LG Display to dominate ever since.

Although Samsung Display says that it will be able to continue supplying its existing LCD orders through the end of the year, there are questions about what Samsung Electronics, the largest TV manufacturer in the world, will use in its LCD TVs going forward. Samsung told The Vergethat it does not expect the shutdown to affect its LCD-based QLED TV lineup. So for the near-term, nothing changes.

One alternative is that Samsung buys its LCD panels from suppliers like TCL-owned CSOT and AUO, which already supply panels for Samsung TVs. Last year The Elec reported that Samsung could close all its South Korean LCD production lines, and make up the difference with panels bought from Chinese manufacturers like CSOT, which Samsung Display has invested in.

Samsung has also been showing off its MicroLED display technology at recent trade shows, which uses self-emissive LED diodes to produce its pixels. However, in 2019 Samsung predicted that the technology was two or three years away from being viable for use in a consumer product.
