led vs lcd monitors comparison manufacturer
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.
An edge-lit monitor may not be the best for picture quality as the lights are only at the edges of the screen. However, screens with edge lighting have become very popular nowadays as the best budget choice. The edge lights allow for the creation of thin monitors at a low price which enhances their affordability.
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.
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.

LCD monitors have been around longer, so they’re more affordable. However, LED monitors are more energy-efficient, lighter and support 4K resolutions.
LCDs feature a layer of liquid crystal embedded between two panels. Images are created when fluorescent lamps behind the screen shine through the crystals and illuminate them.
There are various types of backlights used in LCD monitors, but the most common is cold cathode fluorescent lamps. Essentially, the lights used for CCFL displays are akin to those you see in offices, classrooms and stores, except much smaller.
The first few generations of LCD monitors and televisions used this type of backlight and while you can still find LCD monitors with this backlight, it"s becoming less and less common.
Since it’s an older technology, LCD monitors are generally much cheaper than LED monitors. However, despite being less advanced, they still provide a high-quality image. They’re also better suited for brighter environments like living rooms and kitchens since they provide an overall brighter image.
LCD monitors are also less prone to suffer from burn-in image issues. Burn-in refers to an image becoming “stuck” on the screen. This can happen if a static image is left displaying on the screen for too long. Image retention is more likely to happen if you’re a gamer since some video games feature heads-up display elements that rarely move out of place.
Because of the backlight, LCD monitors are bulkier and thicker than LED monitors. They’re also much less energy-efficient due to the energy required to power the fluorescent lamp backlight.
Finally, you’ll get a crisp 1080p high-definition resolution using an LCD monitor, but if you plan to stream 4K content, it’s best to steer clear from them as most LCDs don’t support 4K.
An LED monitor is also an LCD monitor since it also uses a liquid-crystal screen. However, this specific type of display where the backlight is composed of light-emitting diodes instead of fluorescent lamps. You can imagine light-emitting diodes as a series of tiny light bulbs.
Most LED displays feature edge lighting, which means that the LEDs are positioned around the edge of the screen. Some LED displays have a wide-array setup where the LEDs are placed all over the screen.
The overall image quality of an LED monitor is superior as well. Producing true black contrasts is an issue with LCDs due to the type of backlight, but LED screens reduce this problem significantly.
LED displays also have a fast refresh rate and low lag, which makes them ideal for gamers. Also, unlike with older LCD monitors, you’ll be able to stream 4K content.
Since LED monitors are the newer technology, they’re considerably more expensive than LCD monitors. There’s also a higher risk of image retention with LED displays.
This screen is relatively basic but it’s the best LED monitor you’ll get at its price point. It’s sleek, provides a crisp image and comes with both HDMI and VGA ports.
Although the initial price point of an LED monitor is higher, they’re more energy-efficient and have a longer lifespan. You’ll end up saving money in the long run, which makes it a much better investment than an LCD screen.
LED and LCD monitors share a lot of the same scientific qualities. For instance, they each consist of liquid crystals that are used to emit light through a screen and present specially designed images to the human eye. But the way in which these different technologies execute this objective is where they differ from one another. Depending on their main applications, industrial computer monitors can feature either LEDs or LCDs. Keep reading to learn the differences between the two, so you can determine which one is suitable for your specific commercial or industrial applications.
The relationship between LED and LCD monitors is a little bit complex. All LEDs are technically LCDs. LCDs aren’t the same as LEDs. However, both have similar technical properties even though they’re not entirely the same thing and can each be used for various applications.
Both LED and LCD monitors utilize liquid crystals to present images on a screen with the main difference being the type of backlighting that they use. LCD monitors feature fluorescent backlighting, whereas LED monitors use light emitting diodes. The latter has been proven to significantly reduce symptoms of eyestrain by providing a much wider viewing angle and more adjustability. This improves user comfort for long periods of time without causing image distortion.
By far, LED monitors are a lot more suitable for gaming. Just avoid LED screens with edge lighting, as these are very monolithic and don’t allow for any adjustability whatsoever. You have to be sitting directly in front of the screen the entire time for optimal visibility, which can put a lot of strain on your neck shoulders, back, and eyes. Opt for a full-scale LED monitor that’s customizable and adjustable according to your sitting position, height, and optimal viewing angles instead.
OLED, which stands for organic light-emitting diode, plays up the energy efficiency aspect of regular LEDs by allowing individual pixels to be shut off at any given time. OLEDs are also more space efficient than their LED predecessors as they can be made in a much thinner design and the pixels only use power when they’re in use.
QLED, which stands for quantum light-emitting diode, consists of quantum dots. These miniscule phosphor particles become illuminated when a backlight is shone directly on them, which enhances the brightness capabilities of a regular LED.
LCD and LED industrial and commercial monitors consist of liquid crystals and some form of backlighting. Fluorescent backlighting found in industrial LCD monitors consume a lot of energy and place a great deal of strain on the eyes.
Commercial LED displays, on the other hand, softer light-emitting diodes that reduce energy consumption even when they’re turned on for long periods of time and reduce the rate of eyestrain without compromising the video and image quality.

But how do you know which technology is right for your project? As we look at digital signage solutions, there’s one question that always seems to pop up. What’s the difference between Direct View LED and LCD displays?
LED and LCD displays are both good technologies, and which is better depends on your application. LCD is a liquid crystal display. Commercial LED displays are a grid or group of Light-Emitting Diodes or LEDs that make up the image itself. To make things even more confusing commercial, or Direct-View LEDs, are actually very different than their consumer LED cousins. Here are the basics to help you understand what’s the difference between LED and LCD displays and which is better for your project.
LCD displays are an option for either indoor or outdoor signage. The LCD screen is a series of layers, like an onion. LCD displays have lighting on the base layer. Then comes the LCD sheet, which is a liquid housed between two plates. On top is a protective glass layer. If the display is meant for the outdoors, a final coating is added to protect against the elements- whether they’re natural, like weather, or human-caused, like vandalism.
Here’s where the difference starts to get muddy. LCD screens can be back-lit by LEDs. Meaning the lighting layer consists of many little LEDs that light the LCD sheet from behind. In the consumer world, these are marketed as LED screens. While accurate, it’s not the same as a commercial LED screen. When we talk about commercial LED’s we’re talking about Direct View LEDs, but we’ll get into that more later.
LCD displays come in Full-HD (1080p) or Ultra-HD (4K) resolution. 4K resolution has four times the pixels as 1080p. What does this mean in the real world? At about thirteen feet away from a 98 inch 1080p display, you can begin to see pixels. With 4K resolution, this decreases to seven feet before seeing pixels.
Direct View LED use LEDs as the individual pixels that make up the image itself. Pixel pitch is an important concept with Direct View LED displays. Pixel pitch is the distance from the center of one pixel cluster to the center of the next pixel cluster in a LED screen. This can range from .7 mm- 18 mm plus depending on the viewing distance.
A Direct View LED display is made up of different panels. These panels can be grouped into various shapes providing flexibility and scalability. Unlike LCD displays, Direct View LED video walls don’t have bezel lines between each panel. Various Direct View LEDs feature bezel-less panels which are placed together like building blocks. This LED technology creates a seamless viewing experience even for large-scale video walls.
Direct View LEDs can be curved, convex or concave. They can even wrap entirely around a pillar, the full 360 degrees. Since they’re panels, they can be configured in almost limit-less sizes and aren’t confined to the 16x9 aspect ratio.
Sizes:LCD Displays come in sizes provided by the manufacturer and aren’t that easy to customize. Some manufacturers have stretch sizes, but most of the options are at a 16x9 aspect ratio.
Resolution: LCD Displays typically have a higher resolution than LED screens. So, a customer can view the screen at a closer distance without seeing the pixels.
Bezels:If you’re looking for a video wall option, LCD displays do have bezels around each display. Conversely, some Direct View LEDs don’t have any visible bezels, so there will be no line breaks in your content.
Brightness:Direct View LEDs can range from 800–8,500 nits, which exceeds the brightness of most LCDs. Brightness may or may not be an issue, depending on if the display will be indoors or outdoors.
These basic features outline the difference between commercial LED vs. LCD displays. Which is better? It’s a question that can’t be answered without context. The specifics around your project and what you’re trying to achieve will define which technology should be used. Work with an integrator that understands both technologies and can make a recommendation based upon your project. There’s no one-size-fits all solution, but developing a better understanding of commercial LED vs. LCD displays will help you formulate the right questions to ask an integration partner.
If LED screens are simply defined, they are screen systems similar to TV monitor. LCD screens can be considered as the ancestor of LED screens In this text, we will mention the differences between LCD and LED screens. The most basic and significant distinction is that fluorescent lamps are used for illumination goal in LCD screens. However, LED’s, a more up-to-date technology, are used for backlighting in LED monitors. We can list the other distinctions between the two screens as follows;
The picture grade is much clearer than other televisions. The cause for this is that it reflects less than classical televisions even when exposed to highlight. The fact that LED screens are not affected by sunlight is a unique opportunity for effective advertisement.
LED screens and small LED screen panels are extensively used today. Therefore, its usage fields are also very large. LED screens are used in football fields, malls, hospitals, openings, hotels, competitions and many more. As can be seen, the wide usage areas of LED screens provide convenience to people in many aspects. It is preferred because of the nominal cost of some LED screens. And for this reason, its usage area is also wide. LED panels are preferred in the fields of art and culture, visual presentations, classroom boards and logos.
The point of view limitation of LCD screens panels is greater than that of LED screens panels. That is to get a quality view on LCD’s, the screen should be viewed directly from a vertical angle. If viewed from different angles, the view loses its authenticity. LED screens preserve view grade and maintain the wanted realism from whatever angle they are viewed. Therefore, LED screens panels outdoor are more preferred. Because natural color transitions and realistic appearance from all angles are clearly visible.
What resolution should I choose for LED screen variants? For example, a nominal resolution LED screen can be seen clearly from afar. But when you look closely, you will notice that the image is not clear. For this reason, low resolution should be preferred for outdoor large LED screens. In indoor LED screens, high resolution should be preferred so that the viewers look at the screen at eye level and obtain a clear image.

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.
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.
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.

In the world of digital signage, there are two prominent display technologies: LCD and LED. There’s also a considerable amount of misconception about these technologies and how they relate to each other or work together. The blame for much of this confusion can be attributed to the advent of LCD TVs with LED-backlighting technology, so let’s clear that difference up before we move on.
With any digital display, you must have a well working light source so that you can see the picture brightly. Until very recently, TVs have always been backlit—that is, illuminated from behind the display monitor. For a long period of time after television sets were invented, this was done by firing electrons through a “gun” to the screen (tube and projector TVs). In the early 2000s, LCD TVs were backlit by fluorescent bulbs. More recently, however, TV manufacturers began using LED technology as the light source for flat-screen LCD TVs, as this method provided more versatility and uniform picture lighting, therein lies some of the confusion.
As picture displays, there are many differences between LED display features and LCDs. Given advances in LED display technology—and drastically lower cost—both display types can be viable options for a variety of interior spaces. And of course, each has benefits, and each has limitations. To determine the best display for a digital signage project, it’s critical to understand exactly how each display type will perform and why one is better than the other in a given situation. It’s important to compare, not only cost, but also factors such as brightness, durability, size, resolution, vibrancy, and many more features that are on the market.
LED stands for light-emitting diode. By definition, LEDs provide their own light. Once reserved for large-scale, exterior digital displays, direct-view LED signage has emerged as a greatly improved, widely applicable medium, now suitable for virtually all display installations, both indoor or outdoor. In the digital signage industry, direct-view LED displays have now become the norm and work well together.
LCD stands for liquid crystal display. This type of display uses light-modulating properties of liquid crystals. As referenced above, liquid crystals don’t produce light directly; instead, they use a backlight to produce images on the screen. LCDs are used most often in interior applications, where users are in proximity to the screen. With this display technology, ambient light is usually limited and controlled.
Typically, LED displays have a higher up-front cost than LCDs; however, unlike LCDs, LED displays are rugged and durable, even in the most inhospitable environments. Additionally, they can be upgraded and retrofitted relatively easily. For total cost of ownership and longevity, the better option is the LED.
Brightness is typically measured in NITs. One NIT is equivalent to one candela per square meter. The brightness for LED displays ranges from hundreds to thousands of NITs. LCDs have a much lower brightness range feature. LED displays are able to compete in well-lit areas, both inside and outside. In contrast, competing light will severely impact an LCD; many times, this renders the picture unviewable.
While LED and LCD displays can both render most types of content, there are some drawbacks to LCDs. They can sometimes hold the “memory” of an image, and leave behind a residual imprint referred to as “image persistence.” It’s caused when a still image remains on the screen for too long. The colors become “stuck” in place. When the display tries to shift to another color, the crystals don’t want to budge. The result is a color that is slightly skewed from the intended one. LED displays do not encounter this issue.
Video walls are one of the most popular ways to use digital displays in interior spaces. From entertainment venues to other various retail spaces on the market, video walls have wide appeal. This makes the setup more complex than single screens, so it’s essential to have the right screens. LEDs are typically the preferred display for video walls. They are seamless, tiling together with no bezels. In a well-installed application, video walls have excellent uniformity and the widest viewing angles. LCDs can be tiled, but their bezels cause gaps and visual barriers. While there are LCDs with narrow bezels, small seams are still visible, unfortunately.
An LED display can be any size. There are no inherent limitations. They can also be curved, concave, or convex. They can even wrap completely around a pillar for a 360-degree effect. LCDs are typically only available in the standard sizing set by the manufacturer.

Light Emitting Diode (LED): LED is a type of LCD that actually accompanies the advancement of technology. This replaces the fluorescent tube with backlight technology, which produces a clearer picture than the LCD. LED have wider viewing angle than the LCD. It have better black level and contrast in comparison to LCD LCD display. LED delivers better color accuracy in comparison to the LCD. Advantage:LED have very long life.
Liquid Crystal Display (LCD): An LCD is a passive device, which means that it does not deliver any light to display characters, animations, videos, etc. LCD uses fluorescent tubes to lighten the picture, but can’t provide a clearer picture as LED delivers. It delivers good color accuracy, but we can notice the difference if we compare LED and LCD color accuracy. In LCD, the wide-angle decreases with 30 degrees from the center in the image then the contrast ratio.

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.

Digital panel meters (or DPM) typically uses either an LCD (Liquid Crystal Display) or LED (Light-Emitting Diodes) to display information in an alphanumerical format. What are the differences between LCD’s and LED’s and how do you know which one to pick for your application? Read on to find out!
The Liquid Crystal Display (or LCD) is a form of visual display used in electronic devices in which a layer of a liquid crystal is sandwiched between two transparent electrodes. The application of an electric current to a small area of the layer alters the alignment of its molecules, which affects its reflectivity or its transmission of polarized light. Liquid crystals do not emit light directly. Instead, they use a backlight or reflector to produce images in color or monochrome.
To take it a step further, LCD displays also come in two different variations: Positive LCD and Negative LCD. Essentially, a positive LCD display features dark-colored or black numbers/letters on a light-colored background while a negative LCD display features light-colored numbers/letters on a dark background.
Light-Emitting Diode (or LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light is determined by the energy required for electrons to cross the bandgap of the semiconductor.
While the underlying technology is the main difference between LCD’s and LED’s, there are other features that set these 2 apart from each o
