led vs lcd panel in stock

For companies interested in jumping into the world of video walls, or even upgrading your existing technology, the biggest question you’ll have to deal with is whether LED or LCD is right for your video wall.

Technically, LED displays are just LCD displays. Both use Liquid Crystal Display (LCD) technology and a series of lamps placed at the back of the screen to produce the images we see on our screens.

The main difference between the two technologies is that for LCD displays, the lamps at the back of the screen are fluorescent, whereas LED displays use Light Emitting Diodes.

There are two types of LED backlighting technologies; edge lighting and full array lighting. In edge lighting – as the name suggests – the LEDs are placed along the edge of the screen whereas in full-array lighting, an array of LEDs spans the back of the LED screen. In both cases, local dimming may or may not be used. The majority of LED displays are edge-lit without local dimming.

Image quality is one of the most contentious issues when it comes to the LED vs. LCD video wall debate. LED displays generally have better picture quality compared to their LCD counterparts. From black levels to contrast and even colour accuracy, LED displays usually come out on top. Among LED screens, full-array back-lit displays with local dimming provide the best picture quality. There is usually no difference in terms of viewing angle. This instead depends on the quality of glass panel used.

The question of viewing distance may crop up in LED vs. LCD discussions. In general there is not a huge distance between the two technologies. If viewers will be watching from up close the screen needs a high pixel density regardless of whether your video wall uses LED or LCD technology.

It’s generally accepted that LED displays have the lowest energy consumption levels of all displays. LCD displays commonly consume more energy than plasma and CRT displays, neither of which are in production.

In their research, CNET found that “No question, LED LCDs have the lowest energy consumption” in a comparative test between plasma, LCD and LED displays.

LED displays also win in terms of thickness, or lack thereof The reason, once again, being the advanced lighting technology. To start with, light emitting diodes are much smaller compared to the fluorescent lamps used in LCD displays.

Secondly, when the LEDs are placed at the edges as opposed to the back end of the display, the resulting screen will obviously be thinner. This explains why edge-lit LED screens are the slimmest displays available.

If your main concern is budget, then LCD is the obvious choice. As this article points out, you can usually buy a much bigger LCD display for vastly less money than an LED. LCD video walls are generally much cheaper compared to similar sized LED displays.

LCD software allows you to select the right amount of output for a video wall. You can plug a media player into a video wall processor or a daisy chain of displays. With LED displays, however, all cabinets have to plug directly from the video encoder or player. Either that or all cabinets have to be daisy chained together.

There are tons of screens available in the market today. However, LED screens and LCD screens are by far the most popular. But what is the difference between LCD vs. LED screens?

LED screens feature light-emitting diodes lights installed in the screens. The screens can be volatile or static, with some of them only responding to touch. Other LED screens will display pictures even when turned off.

Some of the benefits of LED monitors nclude enhanced picture quality and local dimming. Local dimming helps to dim down certain areas of your TV"s backlight. This helps to make the screen appear darker and better in displaying blacks.

LED backlighting is an essential feature in offering realistic pictures. The features enhance the popularity of the LED screens (check out the Viewsonic TD2230 Review).

The main difference between LCD and LED displays is that the LCD screens come with a layer of liquid crystals. The liquid crystal layer is put between two plates. Images are made when light passes through parts of the liquid crystal.

The liquid crystal part either block or enhance an area which helps to create the image. Most LCD panel types have LED lights that help bring out the image.

Older LCD screens and use Cold Cathode Fluorescent Lamps (CCFLs) to light the screen. The CCFLs use electron discharge and fluorescence to light the screen.

LEDs like the one from our "Dell Computer Ultrasharp 24.0-Inch Screen LED Monitor Review" are taking over the market while LCD screens with CCFLs are fading away. LCD screens are used in watches, some notebook computers, and calculators.

OLED stands for organic light-emitting diodes, and it uses an organic compound to create outstanding high-contrast images - OLED screens are more environmentally friendly. They are also thinner than a standard LED screen as they don"t require a thick LED backlighting behind the screen to illuminate it.

On the other hand, you have QLED screens that are created and patented by Samsung. The QLED screens offer more crisp images as they create light with a shorter wavelength.

The Q in QLED stands for Quantum Dot (see Quantum Dot and IPS). The screens have an additional layer between the LCD screen and the backlight of the monitor. The layer allows light to pass through easily and produce better colors than an ordinary LED screen.

Slimmer design:LED screens to come in a slimmer design than their LCD counterparts. This gives them a sleek and elegant look, and it also takes less space.

Cheaper to run:If you are trying to cut down on energy cost, an LED screen will be a better option between the two as it is more energy-efficient. However, LED screens are more expensive than their LCD counterparts. As such, you can expect to pay more initially.

Better color:If you want to enjoy more realistic images, LED will be the better option. The screen offers you better color than other screens in the market. Additionally, it offers a better contrast, which is the range between the darkest blacks and brightest whites on the screen. The enhanced contrast ensures you end up with the most realistic images.

However, if you are working on a tight budget, you may consider an LCD screen. Besides the cost, LED performs better than the LCD screen in all the other aspects.

If you want to find out the type of screen you already have, you can check out the screen"s model number. The model number can tell you if the screen is an LED or LCD.

When it comes to picture quality, LED TVs look better than older LCD TVs. Manufacturers also make a big deal out of LED backlighting because sets that use the technology are usually more energy-efficient than CCFL LCD TVs. Therefore, the money you save on your power bill could eventually offset the extra cost of an LED TV.

You"ll be happy with the picture regardless of what kind of display you buy. Still, LED TV have a few practical advantages that make them a better purchase than the older LCD TVs.

With an LED light, the pixels are either edge-lit or backlit. As such, the lights behind the screen are designed to light up all the pixels in your monitor at once.

LED monitors feature better dimming options without sacrificing picture clarity. They also come with features that reduce eye strain, making them the ideal option if you are spending long hours in front of the screen.

Alternatively, you can go for LCD screens that offer arefresh rate of 120Hz or more. The LCD screens also offer a wider variety of viewing angles, which can offer better comfort.

You can trust an LED monitor to offer you the best resolution for the most precise and crisp images. This enables you to enjoy clear and lifelike images.

When choosing between LED and LCD monitors, there are several factors to consider. Besides the backlighting technology, you should also consider the panel type - see also what types of monitors are there. Various panels have their benefits compared to others.

LED monitors tend to be more expensive than LCD screens, thanks to LED technology being newer and featuring pricier components. Additionally, there is a newer form of LED called the OLED, which stands for Organic Light-Emitting Diodes. These OLED displays are extremely expensive, especially at high resolutions. LED technology, on the other hand, is extremely cheap and readily available.

Are you lost on the best choice between LCD and LED monitors? If you spend a lot of time in front of your monitor, you should ensure you end up with the best quality screen. This will ensure that you get high-quality images and also minimize eye strain.

In the battle between LCD and LED displays, LED comes out as the better option. It offers more crisp and clear images, and it also comes with a sleek and elegant design. However, it can be a little expensive. If you are working on a budget, LCD monitors can make a perfect choice.

LED technology has improved drastically in recent years improving picture quality while driving costs down. LED is a bigger investment up front but generally has a lifespan of about 100,000 hours. LCD is cheaper and generally more familiar. A LCD screen typically has a lifespan of about 50,000 hours.

Sort of. Older technologies like LCD technology and Plasma displays are becoming obsolete due to the intrinsic properties of LEDs like brightness, efficiency, maintainability, and sustainability.

LCD screens emit blue light and thus negatively affects not only vision but also overall health. Continual extended screen time mainly can impact your eyes in two major ways. When we look at a screen, our blink rate drops significantly, thus causing digital eye strain.

Then there are the technical terms to deal with, such as LED TV, LCD TV, QLED TV, UHD TV, OLED TV, and more. You might feel like you need to be a tech pro just to watch your favourite TV show in the evening or enjoy a game with your friend.

First, an important thing to understand is that the LED (Light Emitting Diode) monitor is an improvised version of the LCD (Liquid Crystal Display). This is why all LED monitor is LCD in nature, but not all LCDs are LED monitors.

LCD technology revolutionized monitors by using cold cathode fluorescent lamps for backlighting to create the picture displayed on the screen. A cold cathode fluorescent lamp (CCFL) is a tiny fluorescent bulb. In the context of this article, LCDs refer to this traditional type of CCFL LCD TVs.

LED monitors took the old technology a step further by replacing the fluorescent bulbs with LED backlight technology. And OLED (organic light-emitting diode) technology improves it even further by eliminating the need for backlighting.

The quality of direct-view LED screens is measured by pixel pitch. The pixel pitch is the distance between two adjacent LEDs on the display. The smaller the pixel pitch, the better the quality of the image.

Since LEDs replace fluorescent bulbs with light-emitting diodes, LED TVs are more energy-efficient than LCDs. A 32-inch LED TV screen consumes 10 watts less power than the same size LCD screen. The difference in power consumption increases as the size of the display increases.

Light-emitting diodes are considerably smaller than fluorescent lamps used in LCD monitors. Fluorescent lamps have a considerable thickness, but the thickness of diodes is next to none. Moreover, countless diodes are assembled in the same plane, so the thickness of the array isn’t increased no matter how many diodes are present.

Edge-lit LEDs have a slight drawback in viewing angle compared to LCDs, because of the position of the light source. However, direct-view LEDs offer a better angle for viewing than LCDs as the light source is evenly spread on the screen.

Since LED displays use full-array LED backlighting rather than one big backlight, LED TVs offer significantly better contrast than LCDs. LCD backlighting technology only shows white and black, but LED backlighting can emit the entire RGB spectrum, thereby providing a deeper RGB contrast.

If you wonder which display will last longer, this debate is also won by LED displays. LED televisions have a longer lifespan of 100,000 hours on average, compared to 50,000 hours provided by LCD televisions.

An LED display provides the option to dim the backlight, along with other eye comfort features. Not only that, it provides a wider viewing angle without harming image quality. Therefore, an LED display is far better for your eyes than an LCD.

In an LED display, a lot of smaller diodes are used and if a diode is damaged, it can be replaced. In an LCD, you will need to replace the entire bulb in case of damage. Therefore, an LED display is easier and cheaper to maintain than an LCD.

Since LEDs are a better and newer technology, the price of an LED display is higher than an LCD. However, this is only when we are considering the purchase cost.

The picture quality of an LED display is far better than an LCD. Due to modular light-emitting diodes, an LED screen produces better control over the contrast, rendering a clear picture. Also, LED provides RGB contrast, which can show truer blacks and truer whites.

Not to forget, they provide a shorter response time as well. Both of these factors result inLED displays having a better picture quality compared to LCD displays.

Since LED displays are considerably thinner than LCDs, they weigh considerably less. On average, an LED screen weighs about half of an LCD screen of the same size.

As you might have noticed by now, LED wins the battle with LCD without any doubt. This is because LED displays have an advantage in all the factors that matter when considering a purchase, except price.

Even when you consider the price, you will find that while LED technology is costlier, it provides better value for money in the long run. This is because of the longer lifespan and easier maintenance of LED screens.

They are more attractive too. With the increasing shortage of space in new residential complexes, what better solution than an ultra-thin LED display giving a cinematic experience in the comfort of your home.

LED screens are the first choice among the public today, across generations. All are opting to switch to LED from LCD to make their lives more enjoyable and better.

The modern era has shown a tremendous switch from LCD to LEDdisplay. The innovative introduction of LED screensin the television market, at best quality and decent pricing, has taken the market by storm. Every individual is switching rapidly from LCD to LEDscreens. The reason for the switch lies in the innumerable benefits Led has to offer to its clients. Here at Dynamo LED, we offer both LED and LCD, and we appreciate the benefits of both technologies.

An liquid crystal display) uses CCFL’s, which is more power-consuming than LED. The CCFL dissipates more light than the LED, and hence they even tend to make the television warmer to touch with prolonged use. This even makes the LCD more prone top catching fire than the LED televisions.

The LED is lighter weighted and easily portable compared to LCD television. The LED is also more affordable and economical than the LCD now. The long-lasting superior quality makes it more worth to invest in an LED than an LCD.

Eye safety is a major concern in today’s modern era, where people are always working in front of a laptop or computer screen. It is recommended by experts to invest in LED displayscreens to work on desktop, laptops, or even watch television. The LED have far better display panel in the prospective of eye safety, picture quality, and power consumption. Both LC and LED make use of Liquid crystal display, but the difference lies in the backlight, which is majorly responsible for the effect on the eyes. The regular LCDs use a cold fluorescent cathode display backlight, and the LED uses Light Emitting diodes. The LED backlighting is smaller and much safer for the eyes.

The picture quality of the LED display is far better than the LCD. The LED uses an RGB contrast, which makes the pictures almost come alive on the television screen giving its viewers an enjoyable experience.

Though these benefits make LEDs the first choice, it is important to state very clearly that LEDs are not at all cheap. Though the long durability, high-quality picture, the energy-saving feature, and eye safety technology makes it worth the investment compared to less durable and little lower quality LCD display. Why settle for less when the bigger and better product is available at a little higher price,, giving innumerable benefits to its consumers. The LED may be bulkier in price but definitely worth it.

Besides better picture quality, LED Televisions are also energy efficient. They consume very little energy compared to LCD televisions. There is an almost 50% reduction in the power consumption for LED televisions.

It is often claimed that LCD TVs’ lifespan is around 75,000 hours, whereas with LED TVs, you can expect up to 100,000 hours. This is clearly 25% more on average, so LEDs are the clear winner here.

The LED is often regarded as a third-generationdisplay. It meets the demands and preferences of the new generation very much. They are more attractive in designs too. With the increasing shortage of space in the new residential complex, what better than the ultra-thin LED display giving a cinematic experience in the comfort of your homes. LEDs are the first choice among the public today, be it the old generation or the new young youth. All are opting for a switch to LED from the LCD to make lives more enjoyable and better.

Shopping for a new TV is like wading through a never-ending pool of tech jargon, display terminology, and head-spinning acronyms. It was one thing when 4K resolution landed in the homes of consumers, with TV brands touting the new UHD viewing spec as a major marketing grab. But over the last several years, the plot has only continued to thicken when it comes to three- and four-letter acronyms with the introduction of state-of-the-art lighting and screen technology. But between OLEDs, QLEDs, mini-LEDs, and now QD-OLEDs, there’s one battle of words that rests at the core of TV vocabulary: LED versus LCD.

Despite having a different acronym, LED TV is just a specific type of LCD TV, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen. These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to align, so that light can (or can’t) pass through. Think of it as a shutter, either allowing light to pass through or blocking it out.

Since both LED and LCD TVs are based around LCD technology, the question remains: what is the difference? Actually, it’s about what the difference was. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.

Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs. For those interested, we’ll go deeper into backlighting below, or you can move onto the Local Dimming section.

Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. Each of these illumination technologies is different from one another in important ways. Let’s dig into each.

CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. This affects some aspects of picture quality, which we discuss in more detail below. Since CCFLs are larger than LED arrays, CCFL-based LCD TVs are thicker than LED-backlit LCD TVs.

Full-array backlighting swaps the outdated CCFLs for an array of LEDs spanning the back of the screen, comprising zones of LEDs that can be lit or dimmed in a process called local dimming. TVs using full-array LED backlighting to make up a healthy chunk of the high-end LED TV market, and with good reason — with more precise and even illumination, they can create better picture quality than CCFL LCD TVs were ever able to achieve, with better energy efficiency to boot.

Another form of LCD screen illumination is LED edge lighting. As the name implies, edge-lit TVs have LEDs along the edges of a screen. There are a few different configurations, including LEDs along just the bottom, LEDs on the top and bottom, LEDs left and right, and LEDs along all four edges. These different configurations result in picture quality differences, but the overall brightness capabilities still exceed what CCFL LCD TVs could achieve. While there are some drawbacks to edge lighting compared to full-array or direct backlight displays, the upshot is edge lighting that allows manufacturers to make thinner TVs that cost less to manufacture.

To better close the local-dimming quality gap between edge-lit TVs and full-array back-lit TVs, manufacturers like Sony and Samsung developed their own advanced edge lighting forms. Sony’s technology is known as “Slim Backlight Master Drive,” while Samsung has “Infinite Array” employed in its line of QLED TVs. These keep the slim form factor achievable through edge-lit design and local dimming quality more on par with full-array backlighting.

Local dimming is a feature of LED LCD TVs wherein the LED light source behind the LCD is dimmed and illuminated to match what the picture demands. LCDs can’t completely prevent light from passing through, even during dark scenes, so dimming the light source itself aids in creating deeper blacks and more impressive contrast in the picture. This is accomplished by selectively dimming the LEDs when that particular part of the picture — or region — is intended to be dark.

Local dimming helps LED/LCD TVs more closely match the quality of modern OLED displays, which feature better contrast levels by their nature — something CCFL LCD TVs couldn’t do. The quality of local dimming varies depending on which type of backlighting your LCD uses, how many individual zones of backlighting are employed, and the quality of the processing. Here’s an overview of how effective local dimming is on each type of LCD TV.

TVs with full-array backlighting have the most accurate local dimming and therefore tend to offer the best contrast. Since an array of LEDs spans the entire back of the LCD screen, regions can generally be dimmed with more finesse than on edge-lit TVs, and brightness tends to be uniform across the entire screen. Hisense’s impressive U7G TVs are great examples of relatively affordable models that use multiple-zone, full-array backlighting with local dimming.

“Direct local dimming” is essentially the same thing as full-array dimming, just with fewer LEDs spread further apart in the array. However, it’s worth noting that many manufacturers do not differentiate “direct local dimming” from full-array dimming as two separate forms of local dimming. We still feel it’s important to note the difference, as fewer, further-spaced LEDs will not have the same accuracy and consistency as full-array displays.

Because edge lighting employs LEDs positioned on the edge or edges of the screen to project light across the back of the LCD screen, as opposed to coming from directly behind it, it can result in very subtle blocks or bands of lighter pixels within or around areas that should be dark. The local dimming of edge-lit TVs can sometimes result in some murkiness in dark areas compared with full-array LED TVs. It should also be noted that not all LED edge-lit TVs offer local dimming, which is why it is not uncommon to see glowing strips of light at the edges of a TV and less brightness toward the center of the screen.

Since CCFL backlit TVs do not use LEDs, models with this lighting style do not have dimming abilities. Instead, the LCD panel of CCFL LCDs is constantly and evenly illuminated, making a noticeable difference in picture quality compared to LED LCDs. This is especially noticeable in scenes with high contrast, as the dark portions of the picture may appear too bright or washed out. When watching in a well-lit room, it’s easier to ignore or miss the difference, but in a dark room, it will be, well, glaring.

As if it wasn’t already confusing enough, once you begin exploring the world of modern display technology, new acronyms crop up. The two you’ll most commonly find are OLED and QLED.

An OLED display uses a panel of pixel-sized organic compounds that respond to electricity. Since each tiny pixel (millions of which are present in modern displays) can be turned on or off individually, OLED displays are called “emissive” displays (meaning they require no backlight). They offer incredibly deep contrast ratios and better per-pixel accuracy than any other display type on the market.

Because they don’t require a separate light source, OLED displays are also amazingly thin — often just a few millimeters. OLED panels are often found on high-end TVs in place of LED/LCD technology, but that doesn’t mean that LED/LCDs aren’t without their own premium technology.

QLED is a premium tier of LED/LCD TVs from Samsung. Unlike OLED displays, QLED is not a so-called emissive display technology (lights still illuminate QLED pixels from behind). However, QLED TVs feature an updated illumination technology over regular LED LCDs in the form of Quantum Dot material (hence the “Q” in QLED), which raises overall efficiency and brightness. This translates to better, brighter grayscale and color and enhances HDR (High Dynamic Range) abilities.

And now to make things extra confusing, part of Samsung’s 2022 TV lineup is being billed as traditional OLEDs, although a deeper dive will reveal this is actually the company’s first foray into a new panel technology altogether called QD-OLED.

For a further description of QLED and its features, read our list of the best TVs you can buy. The article further compares the qualities of both QLED and OLED TV; however, we also recommend checking outfor a side-by-side look at these two top-notch technologies.

From panel technology to refresh rates, there are a lot of things to consider when looking for a new gaming monitor. To aid you on your journey for the perfect setup, we"re breaking down two of the most common display technology terms: LED and LCD. Here"s what you need to know about LED and LCD screens, what the terms stand for, and how they factor into modern gaming monitors.

LCD stands for liquid-crystal display, which refers to how the monitor works. Behind the screen, liquid crystals are sandwiched between two layers of glass and used to change the colors of pixels to create the images that you see. The whole process is a lot more complicated, but that"s the gist of how LCDs function.

In the past, some LCDs were backlit by CCFLs (cold-cathode fluorescent lamps). LCDs with fluorescent backlighting have been around longer, so if you can find one, they will be cheaper than LED monitors. However, if you"re a gamer looking for decent refresh rates and response times, it"s going to be hard to find a monitor with fluorescent backlighting. They"ve almost completely been replaced by LCD monitors with LED backlights.

LEDs work in a similar way; in fact, you can consider LEDs a subcategory of LCDs. The only difference between some LCDs and LEDs is the type of backlighting: LEDs use LED (light-emitting diodes) backlighting.

In contrast to fluorescent backlighting, LED backlighting generally provides brighter colors and sharper contrast. The monitors are also thinner in size and, in the long run, more energy efficient than LCDs with fluorescent backlights. LED backlighting is the newer technology and the current standard for monitors with high refresh rates and fast response times. When you see LCD in product descriptions, they"re almost always LCD monitors that use LED (as opposed to fluorescent) backlighting. For example, BenQ"s EL2870U monitor is listed as an LCD, but it"s an LCD with LED backlighting.

There are different types of LED backlighting: edge-lit and array-lit. In edge-lit monitors, the lights are placed around the edges of the monitor. Light guides are then used to diffuse the light evenly across the screen. In array-lit monitors, lights are placed behind the screen in a pattern.

For example, some edge-lit and array-lit LEDs have local dimming capabilities, a feature that can selectively dim certain zones of LED lights. Local dimming improves contrast ratio and provides deeper blacks in dimly lit scenes. These monitors, however, tend to be pricey. Some well-reviewed options include the Samsung Odyssey G7 and Philips Momentum 436M6VBPAB, both of which are edge-lit monitors with partial local dimming capabilities. The Acer Predator X35 is an (expensive) full-array monitor with full local dimming (FALD) capabilities.

You won"t have much of a choice between LED or LCD. Most monitors, regardless of whether they"re marked as LED or LCD, will use LED backlights. LED backlights became the new standard because they allow manufacturers to make thinner, more energy-efficient monitors with better graphics. It"s not worth going out of your way to find an LCD with fluorescent backlighting, unless you really, really hate LED lights.

Which backlights a monitor has isn"t as important as other factors such as panel technology, refresh rates and response time, G-Sync vs. FreeSync, and HDR --those are the characteristics you should pay more attention to when choosing a monitor. If you"re not looking to break the bank, a couple of great LED monitors at excellent price points we can recommend are the Asus VP249QGR, a nice budget 1080p monitor, and Acer XF250Q Cbmiiprx 24.5, a well-reviewed budget 240Hz monitor.

Sometimes the distance between good and great seems like hardly any distance at all — such as liquid crystal displays (LCDs) versus light-emitting diode (LED) displays. Both are suitable for retail window signage, campus wayfinding or large video walls. But LCD and LED have significant differences, and their specific benefits are worth understanding so you can choose the best displays for your business needs.

LCD is the broader category; LED is a subset. In other words, all LED displays are LCDs, but not all LCDs are LED. LCDs are made up of hundreds of thousands — even millions — of individual pixels built from liquid crystals. Each pixel is capable of displaying a color when it receives an electrical charge. Like a mosaic, the displayed image is built from tiny elements that combine to form the overall picture.

But the liquid crystals don’t produce any light of their own, so in order for the image to be illuminated, the liquid crystals need to be backlit. LCDs are illuminated by cold cathode fluorescent lamps (CCFLs), evenly positioned behind the pixels so that, at least in theory, every part of the screen is evenly lit and at consistent brightness.

Up to a point, LED displays are much the same. An LED screen also uses liquid crystals to generate color — or pure black (no color), by not charging a specific pixel. So LED displays have the same need for backlighting. But rather than CCFL, tiny individual lights (light-emitting diodes) illuminate the liquid crystals.

The individual LEDs can be arranged one of two ways: full-array or edge-lit. For edge lighting, the LEDs are arranged around the edges of the back of the screen. Full-array, on the other hand, calls for many LEDs to be lined up evenly across the back of the screen, where they can be arranged into zones (usually called “dimming zones” or “local dimming”).

Is LED just plain better than LCD? Well, for a while, LCD screens represented the cutting edge of digital signage. But now, about the only meaningful advantage of LCD over LED is price point. As LCD is becoming outdated, it tends to be less of an upfront investment. In every other respect, though, LED displays have the advantage.

No matter the arrangement of the backlighting, LED has a greater nit value than LCD, which means it’s brighter (“nit” comes from the Latin “nitere,” meaning “to shine”). The average nit value for LCDs is between 500 and 700 nits, while LEDs are typically between 1,200 and 2,400 nits. With greater brightness comes greater contrast, and all-day visibility on outdoor displays.

Despite the energy output, higher brightness doesn’t necessarily mean a shorter lifespan. In fact, LED displays have an average lifespan of 10 years — double the average five-year lifespan of LCDs. Factoring longevity into the cost of your signage, LED’s longer lifespan can make it cheaper than LCD in the long run.

Even with edge lighting, LED produces more vividly lifelike images than CCFL-backlit LCDs — and with sleeker hardware, thanks to their minimalist design. And while LCD bezels have drastically reduced over time, they’re still greater than zero. LED has no bezels at all.

Full-array backlighting requires a little more depth to the screen, but with discrete dimming zones, LEDs can be illuminated far more precisely — which, in turn, means more accurate and engaging visuals.

LED isn’t the first technology to realize miniaturization is the way forward. Even as screens get bigger, the next big step is made of smaller parts: microLEDs.

Up to 40 times smaller than regular LEDs, microLEDs allow backlighting to be even more precisely targeted, with many times more diodes. This, in turn, delivers a more accurate picture, with greater contrast and highly focused areas of brightness. Samsung’s The Wall is a spectacular example of what microLED is capable of.

Whether you need your digital signage to entertain, inform or simply impress, understanding the differences between LCD and LED will allow you to make a better-informed decision.

A Liquid Crystal Display (LCD) is one of the most enduring and fundamental technologies found in monitors, televisions, tablets, and smartphones. TVs and monitors once used cathode ray tubes (CRTs) to provide the image on your screen. But CRTs were bulky and contained dangerous chemicals. Once LCDs became affordable, they replaced CRTs.

An LCD features a panel of liquid crystal molecules. The molecules can be induced using an electrical current to take certain patterns which either block or allow light to pass through. An LCD TV or monitor has a light source at the rear of the display, which lights up the crystals. LCDs commonly use Cold Cathode Fluorescent Lamps (CCFL) to provide the TV or monitor backlight.

To provide a color image on your screen, the LCD has red, green, and blue sub-pixels in each screen pixel. Transistors within the display control the direction of light each pixel emits, which then passes through either a red, green, or blue filter.

Light Emitting Diodes (LEDs) are small semiconductors that emit visible light when an electrical current passes through them. LEDs are typically more efficient and longer-lasting than traditional lighting.

While manufacturers often use "LED" in place of "LCD," an LED TV is also a type of LCD. Instead of CCFL tubes to provide the LCDs backlight, rows of LEDs provide the backlight. The LEDs give better control of the light, as well as greater efficiency as it is possible to control individual LEDs.

For accuracy, a TV or monitor description should read "LED-Backlit LCD Monitor." But that is a) a mouthful and b) doesn"t allow for the creation of a separate marketable product. That"s not to say there aren"t differences between the two.

However, both LED and LCD monitors have different technologies that make certain panels more appealing to gamers, film buffs, designers, and so on. You should also note that on older screens, the difference between an LCD and LED TV or monitor is more pronounced, due to the relative age of the two lighting options.

There are several different types of LED and LCD monitors. When you"re trying to buy a new TV or monitor, understanding the differences and the terminology will help you bag a better deal. Here are some of the most common variations of the LED and LCD panels.

An Edge-Lit LED TV or monitor has its LEDs arranged around the rim of the display, behind the LCD panels facing the screen. The Edge-Lit option allows for slimmer designs, uses fewer LEDs, and can bring the cost of a new screen down. Light reflects across the screen uniformly to create the image.

One downside to an Edge-Lit screen is the dark contrast. Because the Edge-Lit LED display is brightest closer to the edges, color uniformity and black levels can become an issue, with some areas appearing darker than others.

A Full-Array LED display uses a grid of LED lights behind the LCD. The LEDs shine outwards directly towards the LCD, creating a bright and uniform picture. Full-Array LED panels enjoy the efficiency benefits of LEDs.

For the best image reproduction, a Full-Array LED display may include local dimming. Local dimming means that groups of LEDs can switch on and off as required to provide better overall control of the brightness level.

LEDs are often referred to as emitting white light. Actually, LEDs produce light closer to yellow than a pure white. That difference can create a color shift in the image you see on your screen. To improve on this issue, some manufacturers replace white LEDs with groupings of red, green, and blue (RGB) LEDs.

The display uses advanced electronics and programming to control the RGB LEDs accurately, along with more LEDs. The combination increases the cost of an RGB LED screen significantly for what most viewers would consider a marginal improvement. RGB LED displays never became mainstream because of their higher cost.

Organic Light-Emitting Diodes (OLED) are an advanced form of LED lighting found in some LED monitors. Each pixel of an OLED TV can glow or dim independently, resulting in much better black levels, extremely sharp colors, and better contrast ratios. The majority of OLED TVs and monitors have excellent viewing angles and color quality.

Without a doubt, OLED TVs and monitors (and even smartphone screens) have incredible color depth. But that does come at a cost. The latest generation of flagship smartphones all feature OLED screens, and it is a contributing factor to their massive cost. Another consideration is power. An OLED screen consumes more power than other LED-backlit screens and standard LCD screens.

The acronyms continue with QLED, which stands for Quantum Dot LED. Samsung"s QLED improves color accuracy as much as 90-percent from a regular LED TV or monitor and can hit the high levels of brightness and color depth that HDR requires.

So, what is a quantum dot monitor? In short, quantum dots are semiconductor nanocrystals that absorb light at one wavelength and output it at a different wavelength. The LEDs in a QLED emit all of the blue shades the picture requires. But a blue picture isn"t what consumers want. The quantum dots refract the blue LED light into the green and red shades needed to complete the picture.

A single quantum dot monitor or TV contains billions of semiconductor nanocrystals. Those nanocrystals give QLED screens outstanding black range and color depth, as well as excellent color saturation and contrast.

Just as there are types of LED monitor technology, so is there LCD monitor and TV technology, too. The type of LCD tech powering your screen makes a difference to the final picture. Here"s what you need to look out for.

Twisted nematic (TN) was one of the first LCD panel types, dating back to the 1980s. TN panels have fast response time. Most of the fastest gaming monitors use a TN LCD panel to offer exceptionally fast refresh rates, up to 240Hz. That level of refresh isn"t necessary for most people, but it can make a difference for top-level gamers (for instance, in reducing motion blur and image transition smoothness).

Vertical alignment (VA) panels originated in the 1990s. The liquid crystals in a VA panel are aligned vertically, as the name suggests. The vertical alignment structure allows VA panels to produce much deeper blacks and more vibrant array of other colors in comparison to a TN panel. A VA panel usually has better contrast, too.

While a VA LCD panel has a better color range than a TN panel, they also have a slower refresh rate. They also usually cost more and, as such, are rarely marketed toward gamers. Between TN panels and IPS panels (read below), VA is the least popular LCD panel technology.

In-Plane Switching (IPS) panels are considered the best LCD panel technology for a variety of reasons. An IPS panel offers very wide viewing angles with very fast refresh rates. They"re not as fast as a TN panel, but IPS panels are widely available at 144Hz. At the time of writing, the first few 240Hz IPS LCD panels are hitting the market, although they are extremely expensive for a marginal gain.

Color-wise, IPS panels are excellent. High-quality IPS LCD panel prices continue to fall. However, there are several reasons why you shouldn"t buy a ridiculously cheap IPS gaming monitor.

The type of LCD panel you need depends on its use. Gamers want fast response times and rich depth of color, which is why IPS panels are a great option. If you"re more concerned about picture quality for your favorite films, an OLED panel will perform extremely well.

Still, now you know the terminology behind LCD panels and the pros and cons to each type, you can make an informed decision for your TV or monitor upgrade. But wait, the type of LCD or LED panel isn"t the only thing to consider. Take a moment to learn about the differences between 4K, Ultra HD, and 8K screens.

Choosing the right display for a video wall can be overwhelming and confusing. Screens are growing in size, resolutions are increasing, and there are new, more advanced video display options available each year. The first question to address is whether to use an LCD or LED display. Before deciding, it’s important to understand the purpose of each.

Advantages of LCD Video Wall DisplaysLCD, or liquid crystal display, is a type of flat panel that has been popular for years, not only in video walls, but most smartphones, computer monitors, and television screens. An LCD panel is constructed by sandwiching a layer of liquid crystal between two pieces of polarized glass. Liquid crystal is a fluidly flowing material with molecules that can be oriented by applying an electric current. However, liquid crystals don’t produce their own light, necessitating the use of backlights positioned behind the glass to illuminate the display. LCD displays are bright, affordable, reliable, and produce brilliant, fluid color. In addition, LCD displays are extremely high-resolution and able to display text, images, and video in sharp detail, making them a great option for video wall applications.

Advantages of LED Video Wall DisplaysA direct view LED display uses thousands of light-emitting diodes to create an image. Unlike LCDs, the LEDs don’t require a backlight, instead producing colored light when a particular voltage is applied to them. Red, green, and blue LEDs are grouped on the panel, creating the full-color pixels needed to produce an image. LED displays were once a lower-resolution option largely used outdoors, but the development of smaller LEDs in recent years has produced much higher resolutions suitable for indoor video walls. LED displays are bright, reliable, energy-efficient, and offer the best color accuracy and refresh rates of any display type available today. These qualities make LEDs an excellent choice for large-scale digital displays that demand high-impact visuals.

Comparing LCD and LED DisplaysWhen LCDs are tiled together to create a video wall, bezels are visible between the individual panels. By contrast, LED panels have no bezels, so they can be tiled together to form a completely seamless video wall. Higher-resolution LED walls are still several times more expensive than comparable LCD displays, but offer a longer lifespan, with less color matching and burn in issues. LED tiles are also lighter than most LCD walls, and perhaps most importantly, much brighter.

This isn"t the same technology they use for the giant screens at football games; in fact, the LED screens you see in shops are actually LCDs, and the term "LED" is the invention of Samsung"s marketing department.

How do they get away with this? Samsung"s televisions use a series of Light Emitting Diodes (LEDs) — like the ones used in LED torches and alarm clocks — to "backlight" the LCD panel, and it"s not the only company that does this. But what is backlighting, anyway?

As a consumer technology, LCD has been in widespread use since the early "70s where it first appeared in digital watches. As its name suggests, Liquid Crystal Display is a liquid that has been sandwiched between two plates, and it changes when a current is applied to it.

While we"ve had black-and-white LCDs for years, colour LCDs are a lot more recent, but the technology is the same. As we all know, you need to press a button to read a watch in the dark, and an LCD TV is no different. It needs a light behind it because it emits no light of its own.

It"s helpful to think of an LCD panel as a sandwich, consisting of different layers. On a typical TV you have a polarised filter, followed by a protective glass layer, followed by the LCD sheet, and then a light source at the back.

At present, there are two main methods of backlighting in LCD flat-panels: Cold-Cathode Fluorescent Lamp (CCFL) and LED (light-emitting diode). There are several others, and this includes Sony"s Hot Cathode Fluorescent Lamp (HCFL), but only

CCFL backlighting consists of a series of tubes laid horizontally behind the screen. It used to be the most common method of backlighting for LCD televisions, but it is quickly being superseded by LED.

LED backlighting has been in use in televisions since 2004 when it first appeared on Sony WEGA models. Though there are several different ways of backlighting using LEDs (as we"ll explain shortly), the idea is the same: a series of LED bulbs throw light from behind to illuminate the LCD panel.

There are two different methods of LED backlighting: direct and edge. The main advantage of direct lighting is that it can be used to increase contrast levels by turning some LEDs off — thus increasing the amount of black in parts of the picture. LG is one of the champions of direct lighting.

In comparison, edge lighting"s main advantage is that it can be used to make screens that are incredibly thin — the LEDs are at the side and not behind the screen. Of course, you lose the ability to switch off parts of the backlighting for better contrast, and picture quality could also suffer if light isn"t sufficiently well dispersed.

White LED is very similar to CCFL, and is meant to simulate the white light of the sun for a more "natural" result. But the LEDs aren"t actually white; this approach uses a blue light source that is made to look white by the presence of a sulphur coating on the bulb. CCFLs work in the same way.

As a result, the television could potentially be stronger in the green portion of the spectrum, but some CCFL technologies enable better red and blue response, so better white LEDs could also be possible. The

RGB LEDs, on the other hand, are potentially capable of a broader colour range because they use three LEDs coloured red, blue and green, which is a broadcast standard. RGB"s proponents argue that there is less of a green "push" as a result, and the colour spectrum is more evenly distributed. The Sony Bravia KDL-46XBR45 is an example of a television that used RGB LEDs in its backlight.

Here we have Samsung"s edge-lit LED unit, which comprises of two major components: a long LED module of tiny white diodes and a thin screen-sized plastic sheet known as a light guide plate. Four of these LED modules are deployed along the left, right, top and bottom of the television. The combined light output is then funnelled and redistributed evenly across the screen by the light guide.

We find it interesting that TV manufacturers are still asking for a higher price for LED-backlighting when many cheap devices — particularly mobile phones and netbooks — use LEDs as backlights. As of 2009, Samsung said that LED backlights cost three times more in large sizes than the equivalent CCFL arrangement, and this is mostly due to a lower number of manufacturers. Presumably, as the technology continues to take a firmer hold, the price will keep coming down.

In 2011, only the budget LCD televisions use CCFL backlighting, and all of the major manufacturers use LED lighting in their mid-range and premium models. It won"t be too long before it will become the default method of backlighting. While some people still prefer the look of a plasma, the LED"s combination of thin design and sharp picture quality will soon find favour with many people. If you"re looking for a further explanation of how LCD screens work, then you can try this video on the 3M site.

Even though some say the picture quality of an LED TV is better, there is no straight answer for which has better picture quality since both TVs use the same kind of screen. For instance, a higher-end LCD TV can have a better quality than a low-end LED TV, but if you look at high-end models of either TV, the picture quality will be comparable.

RGB Dynamic LEDs show truer blacks and whites and thus get higher dynamic contrast ratio (which is desirable in a TV), at the cost of less detail in small bright objects on a dark background (such as star fields)

LED TVs use energy-efficient light emitting diodes (LED) for backlighting. These consume less power than cold cathode fluorescent lamps (CCFL) used in traditional LCD televisions. Power savings are typically 20-30%.

Edge-LEDs (the most common) are positioned around the rim of the screen and use a special diffusion panel to spread the light evenly behind the screen.

Flat Screen LCDs, about an inch or two thick are more expensive, but also more popular because of their sleek look and the flexible options of standing on a surface or mounting on a wall.

Front projection LCDs or projectors, which project an image onto the front of the screen. The TV itself is just a box installed anywhere in a room, which projects the image onto a flat screen hung on the wall as large as 300 inches.

Rear projection LCDs, where the image is sent from the rear of the TV to the screen in front. Rear projection LCDs are wide, heavy and only available in large sizes (60" and up).

LCD stands for “liquid crystal display” and technically, both LED and LCD TVs are liquid crystal displays. The basic technology is the same in that both television types have two layers of polarized glass through which the liquid crystals both block and pass light. So really, LED TVs are a subset of LCD TVs.

LED, which stands for “light emitting diodes,” differs from general LCD TVs in that LCDs use fluorescent lights while LEDs use those light emitting diodes. Also, the placement of the lights on an LED TV can differ. The fluorescent lights in an LCD TV are always behind the screen. On an LED TV, the light emitting diodes can be placed either behind the screen or around its edges. The difference in lights and in lighting placement has generally meant that LED TVs can be thinner than LCDs, although this is starting to change. It has also meant that LED TVs run with greater energy efficiency and can provide a clearer, better picture than the general LCD TVs.

LED TVs provide a better picture for two basic reasons. First, LED TVs work with a color wheel or distinct RGB-colored lights (red, green, blue) to produce more realistic and sharper colors. Second, light emitting diodes can be dimmed. The dimming capability on the back lighting in an LED TV allows the picture to display with a truer black by darkening the lights and blocking more light from passing through the panel. This capability is not present on edge-lit LED TVs; however, edge-lit LED TVs can display a truer white than the fluorescent LED TVs.

Because all these LCD TVs are thin-screen, each has particular angle-viewing and anti-glare issues. The backlit TVs provide better, cleaner angle viewing than the edge-lit LED TV. However, the backlit LED TV will usually have better angle viewing than the standard LCD TV. Both LED and LCD TVs have good reputations for their playback and gaming quality.

When it comes to choosing the best LED screen for your event, the endless amount of features and specifications can be confusing. Insane Impact is here to help! There are a few critical factors you need to consider when you’re deciding between LED and LCD displays, particularly, viewing distance, the physical location of the screen, the environment in which it’s being showed and the content that’s being displayed.

Take a look at the table below to understand the key differences between LED and LCD screens. Overall, LED is generally preferred because of it’s crystal-clear picture, robust capabilities and general reliability.

LED screens have become a mainstay in the large event category with their optimal picture resolution and capability to emit high light levels. Through use of Light Emitting Diodes (LED), these systems produce red, green and blue light. By combining and balancing these three primary colors, the user can produce virtually any color on the spectrum.

Event screens are typically built from multiple panels that are connected together. These can be customized and scaled to any shape or size, perfect for huge arenas, smaller trade show exhibits and everything in between. Display your custom content on an LED so the entire arena can see.

LED screens can be heavy or large, meaning they require rigging systems. However, mobile LED screens are presenting a unique opportunity for event managers to take complete control of their display system.

LCD screens are normally seen in smaller more consumer-driven displays, such as computer monitors or TVs. This screen option is ideal for small applications where an affordable but high-quality display is needed. Additionally, with a wide range of connectivity options, these screens are versatile.

The clarity of every LED screen is dictated by its pixel pitch. This measurement defines how clear or coarse the video is and how close a viewer can stand to the display and still get a clear visual.

As our table displayed, the pixel pitch of an LED screen is Pixel pitches range from 0.9 – 20mm, while the pixel pitch of an LCD screen is Pixel pitches between 0.5 – 0.6mm. This shows us that LEDs are better for medium to long viewing distances in indoor and outdoor applications, while LCDs are better for close viewing in indoor or nighttime applications only.

While the main LED and LCD difference lies in the technology the TV uses to project visuals on screen, each of the two technologies responds to projections and video in a different way.

An LED TV, owing to the technology it uses, flaunts a thinner screen with sharper edges. On the other hand, the two-layer display technology adds bulk to an LCD TV.

Backlight is an important difference between LCD and LED TVs. An LED TV backlight comes in two ways: edge lighting and full array lighting. Unlike an LCD TV that uses CCFL for backlight, most LED TVs use ‘light guides’ to project pictures on the screen. For example: the latest LED Sony TV and LG TV use the edge lit with local dimming technology to present bright visuals.

When comparing LCD vs LED on the parameter of brightness, an LED TV stands out as a winner. This is because it appoints an individual dimming and backlighting system, which in comparison to LCD, makes your projections more defined, authentic, and closer to reality.

LED TVs have superior black levels and employ dynamic contrast mechanisms as compared to LCDs. Colour precision is also more defined in case of LED TV.

LCDs project clear pictures for up to 165 degrees, but projections tend to distort beyond this point. However, LED TVs are equipped to offer you better clarity at all viewing angles.

LED TVs are more energy-efficient as these models use light emitting diodes (LED) for backlighting. These TVs consume less power as compared to cold cathode fluorescent lamps (CCFL), which most LCD TVs use. This results in a power savings of up to 30%.

Owing to the technology on offer, the price of LED TVs is higher as compared to LCD TVs. For instance, to buy an LED TV that is HD Ready, you will have to spend a minimum of Rs. 10,000 and the price will go up with an increase in screen size and technology. Smart TVs, for instance, come with a higher price tag.

The best part about an LED TV is that it can perfectly fit your space, however limited or expansive it may be, courtesy its versatile size and thickness. You can buy LCDs ranging between 13 and 57 inches in size and LEDs of up to 90 inches, based on the available space.

The most common type of LCD TVs today is the flat screen; however, you can also get front projection LCDs that project an image onto a flat screen. When it comes to LEDs, the most common type is the Edge LED TV that spreads the light uniformly behind the screen. You can also find Dynamic RGB LEDs, which offer dimmer or brighter projections on certain areas, and Full-array LEDs that do not offer dimming or brightening of an individual area.

With this comparison, you must have realised that LED TVs are better than LCDs. However, when choosing a TV, understand your viewing requirement first, then choose what suits you the best. If playing games or watching films in high definition is your passion, then choose LED TVs over LCDs.

In the time to come, OLED technology is going to dominate the LED TV market. While some brands like Sony have already launched exceptional OLED TVs, more is yet to come. Unfortunately, LCD TVs will slowly vanish from the market owing to their cumbersome make and limited features.

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 compr
