led versus lcd display quotation

LED stands for Light Emitting Diode. SMD refers to Surface Mounted Diode, a technology that utilizes a process of mounting each LED chip (pixel) directly to a printed circuit board (PCB). Mounting the diodes in this fashion allows displays to be thinner and sleeker than older LED technology. SMD also allows for finer pixel pitch. Simply put, pixel pitch refers to the distance between the diodes and is responsible for resolution. Fine pixel pitch translates into high resolution. Fine pixel pitch is what makes HD and UHD LED possible.

LCD panels are made of a layer of liquid crystal between two pieces of polarized glass. Liquid crystal can not emit light. Backlights are therefore used to illuminate the display. LCD panels are sleek in design, but typically limited to specific sets of dimensions.

LEDs are their own light source. This means that LED video walls are glare free and not subject to many of the problems ambient lighting creates for other video display types.

LED technology is modular in nature. This means that LED panels fit together seamlessly and can be used to make displays to fit any space. Custom cabinets can even be built to accommodate unusual shapes or dimensions.

LCD video walls on the other hand take on a tiled approach. This means that screens are jutted against one another. This approach creates bezels or seams and the final dimensions of the wall is directly dependent on the dimensions of the individual screens.

LED is a versatile display option. Thanks to various IP options, LED video walls can be displayed indoors or outdoors. LED video walls can be built with a variety of internal mechanisms as well. Quick refresh rates and dual power backup can ensure that LED video walls look great on camera. Various pixel pitches can ensure the proper resolution for the right context.

LCD is a more straightforward product and consumers are generally more familiar with LCD. LCD is used for cell phones, computer screens, and most TVs, but is it the best choice for video walls? Ultimately that choice is up to the consumer. LCD is cheaper, but generally less customizable. LCD does not work well for outdoor uses and is generally very limited in terms of size and shape.

LED technology has improved drastically in recent years improving quality while driving costs down. LED is a bigger investment up front but generally has a lifespan of about 100,000 hours.

Just like anything else, the best video wall product is largely dependant on context. If you like LED technology but are unsure of the process associated in obtaining a LED video wall read: How to Purchase a LED Video Wall Display.

Light-Emitting Diodes (or LEDs) are electrical components that emit light when current flows through them, very similar to a common light bulb. You’ve probably seen these tiny lights around your home, in modern Christmas light strands, night lights, flashlights, lightbulbs, and more.

LED displays are a self-emitting display technology made up of a matrix of red, blue, and green LEDs forming the individual pixel elements. Standard LED displays have hundreds to thousands of LED pixels and project light directly to the viewer. These are often called “Direct View LEDs”, because there is no LCD layer at all in the display. MicroLED is one of the newest forms of these displays, which uses millions of microscopic LEDs producing a much higher-resolution image. However, they are still too expensive to be adopted by many applications. All types of LED displays provide excellent brightness and visibility both indoors and outdoors, but can also be heavy, bulky and require more complex installation. They tend to be expensive upfront but offer some cost savings over time since the light diodes that they rely on require little power. However, LEDs are at a higher risk for poor image retention or what many people refer to as “screen burn”.

Sometimes, LEDs are also used to form a backlight panel which is used to illuminate an LCD. These LED-backlit LCDs are frequently misnamed “LED displays”, however they are not true LED displays. True LED displays do not have an LCD layer.

A video wall is not a one-size-fits-all solution. There are many options to choose from when designing a commercial building video wall display: the size and shape of the digital canvas, what type of content will be displayed and the purpose of the video wall. Operationally, you may focus on desired reliability, maintenance and serviceability of the equipment. Hardware and technology decisions ensure the video wall will deliver both the desired viewing and ownership experience.

One of these choices is deciding between an LCD display or an LED video wall. Continue reading to find out more about the basics, as well as the advantages and disadvantages of each solution.

Most people are familiar with LCD technology, which stands for Liquid Crystal Display. These types of displays have a massive presence in this world, used in living rooms to watch movies, fast-food restaurants to showcase menus, airports to show flight schedules, and everything in between. LCD technology was developed in the 1960s and has been used worldwide as a standard for roughly 20 years. It is a tried-and-true technology that has stood the test of time and will be around for the foreseeable future.

On an LCD screen, the panel is illuminated by a light source and works through reflection or transmission of light. Overall, LCD displays have better viewing angles and less glare than LED screens. This technology was designed to be energy efficient and tends to be lighter in weight.

An LCD video wall is made up of multiple LCD panel monitors mounted on a surface to create a digital canvas, which then work together to create a unified experience. They operate 24/7 at a high brightness and have thin bezels that help create a seamless look when the displays are placed next to one another.

Bezel thickness and the brightness rating are among key attributes to consider for an LCD video wall display. Here is what each of these means and why.

Bezel:Bezel thicknesses for video wall displays are measured in “bezel-to-bezel” thickness.This is the thickness of the bezel when two displays are placed next to one another. Displays can be either large bezel or thin bezel.

Nits:Brightness is measured in Nits. A higher Nit value means the display will be brighter. A brighter display is necessary in a room that sees plenty of direct sunlight, or if the intent is to draw in visitors from far away. With LCD video walls, the price of the hardware goes up as the display size and brightness increase, and the bezel width decreases.

The next item to consider is the type of content that will be displayed on your video wall. LCD displays have high resolution screens — modern 4K displays have over 8 million pixels! This means that the content being displayed is highly detailed and crystal-clear. A viewer could stand less than 1 foot away from the screen and be able to see exactly what is being shown on the screen.

Like previously mentioned with LCD video walls, an important consideration in the decision-making process is the type of content that will be displayed on the video wall. LED video walls suffer from image degradation and pixilation from up close, so fine details will be lost, and text will be illegible. If detail from up close is important, LCD displays are much better suited for that situation.Content examples that are well-suited for an LCD video wall:

Video walls are relatively new. But LCD technology has had decades of mainstream adoption, and with that comes both familiarity and lower costs. If those are important to you, then an LCD video wall is likely the right choice.

LED video walls are similar to LCD video walls, but the digital canvas is built using LED panels. Individual LED panels can be anywhere from 12”x12” to 36”x18”, which is much smaller than LCD displays. LED panels have a larger presence in this world than most might think—they are found indoors and outdoors at stadiums, arenas, concert venues, airports, and in use as large digital advertisements in iconic places such as Times Square.

The module is a small rectangular board that contains all the individual LEDs (light-emitting diodes).Unlike LCD, there is no glass or color filter on the LED video wall panels. The individual diodes that are placed on the modules produce both color and light.

One of the most impressive features of LED panels is that they can be combined to create almost any shape, without a bezel interrupting the digital canvas. LED video wall panels can be placed on curved surfaces, 90-degree edges, and other non-standard surfaces. The smaller size of the panels in relation to LCD video wall displays means they can fill more space on a surface—they aren’t limited to standard 46” and 55” sizes as are LCD video wall displays.

The most important factor to consider when scoping LED panels for a video wall is what is referred to as “pixel pitch.” The pixel pitch is effectively the distance between each pixel on the LED panel—a pixel pitch of 6mm means each pixel is spaced 6 millimeters away from the adjacent pixel. The smaller the pixel pitch, the smaller the distance is between each pixel, which means there are more pixels per square inch on the digital canvas.

Pixel pitch factors into viewing distance. When the pixels are close together, the image is more detailed and can be viewed comfortably by others from a close distance. But when the pixels are spaced further apart, a viewer needs to stand further away to view the image clearly.

Lastly, pixel pitch impacts the price of the LED video wall more than any other factor. For example, a 2mm pixel pitch LED video wall costs significantly more than its 10mm pixel pitch counterpart.

As is the case with an LCD video wall, an LED video wall will add exciting drama and premium value to showcase spaces. LED panel displays don’t enjoy the benefit of decades of mainstream adoption as do their LCD counterparts. However, the technology curve is increasing their availability and lowering their costs. At this time, an LED video wall will have higher upfront costs compared to an LCD video wall. If cost is the main concern, then an LED video wall system will not likely fit into your budget

An LED video wall would be well-suited and cost-justified if the intent of the video wall is to provide an immersive viewing experience from a further distance. This could be content with lots of movement, animation, imagery, and bright colors to draw viewers into your space or provide a unique experience.

Aside from LED video wall cost, there are other factors to consider which could make an LED video wall system the frontrunner for your project. Here are the advantages and disadvantages to consider:

Limitless shapes and sizes:the smaller size of LED panels allows them to be combined to create unique canvases, including curved, 90-degree edge, and other combinations not possible with LCD displays

Easy maintenance and service; high reliability:LED module replacement takes seconds with little effort; LED panels are rated with a lifetime of 80,000-100,000 hours, depending on the product

If you’re in the market to rent a video wall, you’ve probably run into all sorts of confusing info. Here’s the lowdown on LCD vs. LED video walls so you can make the right choice for your next conference, trade show, or other event.

We’re about to throw a whole lot of info at you. So let’s first take a second to remember why both LED and LCD video walls are a good investment in the first place.

The old adage, “the bigger the better,” is definitely true when it comes to AV. A video wall immediately symbolizes your company is established, and sends a subconscious message that people should take your business seriously. Video walls help you stand out, and compete with all the other businesses who are investing in splashy, eye-catching displays.

Once reserved for stadiums and shopping malls, LED walls have become much more accessible for corporate events in recent years. An LED wall is made of many smaller LED panels. Each panel has hundreds of tiny light sources called “light emitting diodes” that can change color to create a large, seamless image.

Technicians can add panels until the LED wall is as massive as you need it to be. Random fact: The Suzhou Sky Screen in China is the largest LED video wall in the world, measuring 1,640 feet long — about 4.5 football fields.

Meanwhile, an LCD video wall is a large surface for video or images built from many LCD screens. You’ve interacted with an LCD screen before — they’re on your laptop, TV monitor, and more. However, the LCD video wall screens are designed to run longer and have thinner edges, called bezels.

Technicians use special hardware and tools to stack the LCD screens on top of one another, and calibrate the wall so that an image shows up across every screen. Temporary LCD walls can usually only be about five screens across and five screens high.

Temporary LCD walls can be configured to be in many different sizes and shapes, both large and small, but typically don’t go larger than five screens across and five screens high.

Our most popular LCD walls are about 16’ wide by 10’ tall. Also, when measuring your ceiling height, keep in mind that most walls don’t go all the way down to the floor. So you’ll need to add that into your total height need.

People need to view LED walls from a distance to get the full picture. Think of them like a Lite Brite, or an impressionist painting — you get the full picture when you’re further away. Though made of LED panels, there are no seams.

The image on an LCD wall will be sharper than on LED walls, especially while standing nearby, since it’s made from HD panels. Will have very thin seams between each LCD screen, called bezels.

Since an LCD Wall are basically fancy computer monitors, it’s typically easier to create content. If your content looks great on a standard computer monitor with a 16:9 aspect ratio, it will look good on an LCD wall. Your AV provider will give you dimensions and resolution requirements once you decide on the size you need, and can also help you determine where the seams (or “bezels”) will be so none of your image gets cut off.

Much lower than LCD — but you’ll still need to make sure your venue has enough power capabilities. Your video wall provider can tell you how much power you’ll need.

Imagine an LCD video wall is like a tray of lasagna. Reliable, beautiful, and sturdy — but you can only increase the size of a tray of lasagna so much. Affordable, but it has a limit in size.

Meanwhile, imagine an LED wall like a limitless, footlong sub. It might not be quite as satisfying and vibrant as a steaming tray of lasagna, but you can keep adding to it until it’s as massive as you’d like.

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.

On home appliances, it is often necessary to display numbers and words to convey information, such as the current time displayed on the clock, the current temperature information on the kettle… etc. The two most commonly used displays are LED displays and LCD displays, this article will compare the advantages and disadvantages of LED displays and LCD displays, and provide a two-step quick way to quickly determine whether this product is an LCD or LED display.

LCD displays are the most common displays in daily life, from your mobile phone screen to home appliances, you can use LCD displays, but whether it is a color or black and white LCD display, in fact, the principle is the same. There are two main components within the LCD display:Backlight module

Black-and-white LCD displays are widely used in a variety of low-cost products, and the picture above is a black-and-white LCD display used in science calculator.

Advantages of monochrome LCD displays:Can show very compact information.Each display point of the calculator as shown below is very close to each other, and high-resolution text can be displayed

Power savingBlack and white LCD displays can operated without a lot of power compared to full-color LCD, when products that do not require full-color demand and need to control power consumption are often used.

CheapIf you just want to display a set of numbers or a few ICONs, the price of using a black-and-white LCD display is much cheaper than that of a full-color LCD, and it is often used in a large number of consumer products.

Disadvantages of monochrome LCD displays:Small viewing angle, not easy to use for outdoor application.Usually black and white liquid crystal display in the front view, the display is the clearest, but due to the LCD panel characteristics, as long as the side view, the clarity will be declined, outdoor will be affected by strong light, the viewing angle is not large, the clarity is not enough, LED display due to the word luminescence characteristics, there is no viewing angle problem.

Can only be used in monochromeIf you need multi-color applications, you can only upgrade to a full-color LCD display that is many times more expensive, and the LED display can simply add different colors to the LED display without significantly increasing the cost

The structure and basic introduction of the display in this article this article, compared with LCD displays, self-illumination characteristics, so that LED displays in the outdoor visibility is high, high brightness, but also no viewing angle problem. LED displays are the same as black and white LCD liquid crystals, and the display information must be designed in advance and cannot be arbitrarily transformed. The price of LED displays is between full-color LCDs and monochrome LCDs, and if properly designed, they can save the cost of achieving display performance.

This article briefly introduces the basic principles and advantages and disadvantages of two common LCD displays, and provides two steps to quickly determine whether the display in hand is an LED display, and product designers can follow these two steps to understand which display the product is used when observing the product.

If you are looking to have custom electronics built that need displays, you will have to choose between LED displays and LCD displays. This can be a confusing choice, as LED displays and LCD displays are quite similar. However, there are a few important differences. To understand why this choice is an important one, you need to know what LEDs are and what LCDs are. This way, you can see the differences between the two technologies. To learn more about LED vs LCD, read on.

An LCD display, also known as a liquid crystal display, has been the dominant display technology for quite some time. It is used for tablets, smartphones, TVs, and computer monitors. Monitors formally used cathode ray tubes, also known as CRTs, to project the image. However, LCD displays eventually became affordable in the late seventies and they replaced CRTs. An LCD works by having a panel of liquid crystal that is forced by a source of electricity to create certain patterns. An LCD display has a light source behind the crystals. Some of our LCD displays can display color. These displays have red, green, and blue pixels within the liquid crystal. When the light turns on and passes through the liquid crystal, it also passes through a red, green, or blue filter.

LEDs, also known as light emitting diodes, are tiny semiconductors that give off light when an electrical current is applied to them. The light is not usually very bright, but it is more energy efficient and lasts longer than traditional lights. LEDs can be used in place of LCDs by some manufacturers. LEDs are actually a type of LCD. Normal LCDs use cooled carbon fluoride tubes, also known as CCFL tubes, to provide the backlight for the LCDs. The LEDs are an alternative to these CCFL tubes. They can give greater control of the light sent to the display. The extra energy efficiency comes from the fact that individual LEDs can be shut off when they aren’t needed for the display. An LCD display is either completely on or completely off. There is no in-between setting like there is with LEDs. LEDs actually come in several different types. These include RGB- LED, full array, and edge-lit LED displays.

As previously mentioned, LEDs are more energy efficient. You may think that using LEDs instead of an LCD for your display will not result in appreciable energy savings. However, this is not necessarily true. It depends on how large the display is on your device, how often it’s on, and on the cost of power. They could add up to hundreds of dollars every year. When you’re trying to cut cost for your company, every little bit counts. Also, keep in mind that better energy efficiency will help make a company more green.

LED displays are also more readable than LCD displays. This is especially true during low-light situations. The pure white backlights of the LED displays means the colors do not get distorted when the display’s brightness is turned up. Also, LED displays tend to be higher resolution. This can prevent to misreading the display, no matter what the conditions are. If the device controls a sensitive function, misreading the display and acting upon this incorrect information could be very serious. An LED display could prevent this from happening. There is a good reason that many of the most advanced electronics in this day in age use LED displays.

Pretty much the only disadvantage of LED displays is that they are more expensive. Just how much more expensive depends on the device and on the application that the device will be used in. In general, they’re only a little more expensive. If your company is on a tight budget and you do not need the advantages that an LED display can provide, you may be better suited going with an LCD display. Otherwise, an LED display may be the best choice for your business. If you’re not sure, you can contact one of our engineers. They will ask you some questions about the application it may be used in and then make an informed recommendation. Of course, the final decision is up to you.

Then there are the technical words, such as LED TV, LCD TV, QLED TV, UHD TV, OLED TV, and others, that need to be understood. You may need to be a tech expert to play a game with a friend or watch your favorite TV show in the evening.

A lot of people are converting from LCD to LED televisions. The numerous advantages that LED screens provide are the driving force for conversion at most tv repair shops in Lawrence, KS.

First and first, it’s crucial to realize that the LED (Light Emitting Diode) monitor is an adapted form of the LCD (Liquid Crystal Display). Because of this, all LED monitors are, by definition, LCDs; however, not all are LED monitors.

LCD technology changed monitors by using cold cathode fluorescent lamps as backlighting to produce the image displayed on the screen. A small fluorescent bulb is a cold cathode fluorescent light (CCFL). This traditional style of CCFL LCD TVs is referred to as LCDs for this article.

By substituting LED backlighting for fluorescent lighting, LED monitors advanced the existing technology. And the absence of backlighting, thanks to OLED (organic light-emitting diode) technology, makes it even better.

This converts a single monitor into an endless modular collection of light-emitting LEDs. Additionally, this increases the size of the monitor without drastically increasing the price.

The pixel pitch is used to assess the performance of direct-view LED displays. The space between two neighboring LEDs on the show is known as the pixel pitch. The quality of the image increases with decreasing pixel pitch.

Due to the location of the light source, edge-lit LEDs have a little narrower viewing angle than LCDs. Direct-view LEDs, on the other hand, provide a better viewing angle than LCDs since the light source is dispersed uniformly throughout the display.

LED TVs use less energy than LCD TVs because they use light-emitting diodes instead of fluorescent bulbs. Compared to an LCD screen of the same size, a 32-inch LED TV uses 10 watts less power. As the display size increases, the power consumption difference grows.

LEDs are far more compact than the fluorescent bulbs used in LCD monitors. The thickness of fluorescent lights is substantial, but that of diodes is virtually nonexistent. The thickness of the array is also unaffected by the number of diodes because they are all arranged in the same plane.

Since LED displays use full-array LED backlighting instead of a single large backlight, LED TVs have a much higher contrast than LCDs. Since LED backlighting can emit the entire RGB spectrum, it can produce a deeper RGB difference than LCD backlighting technology, which can only display white and black.

Moreover, they are more beautiful. What better solution to the growing lack of space in new residential complexes than an ultra-thin LED display that offers a cinematic experience in the comfort of your home?

If you ask tv repair shops in Lawrence, KS, LED screens are the most popular option now among the general public. Everyone is choosing to move from LCD to LED to improve their lives and make them more fun.

If you’re wondering which display will last the longest, LED displays also prevail in this argument. LED televisions have an average lifespan of 50,000 hours compared to LCD televisions, which have a lifespan of 100,000 hours.

The ability to decrease the lighting is one of the eye-comfort advantages of an LED display. Additionally, it offers a broader viewing angle while maintaining the quality of the image. Therefore, compared to an LCD, an LED display is far better for your eyes.

With its first electronics-based applications appearing back in 1962, LED involves the use of a two-lead semiconductor to produce light. The technology is based on a simple principle in which the activation of a pn-junction diode generates light when activated. Voltage is applied to the leads, at which point electrons fill electron gaps or holes within the device, causing it to release photon (light) energy.

As the name suggests, liquid crystal displays use lighted, liquid crystals to produce the display. Contrary to what some people may believe, however, the actual crystals do not emit light. Instead, light is created through an alternative source, such as a back-lit display, and projected through the crystals. Within an LCD, you’ll find a layer of molecules that are aligned with two transparent electrodes and polarizing filters. The polarizing filters allow the light to pass through without being be blocked.

One of the advantages of LCD is its efficient use of energy. LCD is often used in battery-powered watches, alarm clocks, and other devices for this very reason. While LED or other types of display technology could technically be used for such purposes, the device would die faster and thus require more frequent recharging or replacing of the batteries. LCD solves this problem by using minimal energy when compared to other types of display technology.

There’s really no easy answer to this question, as it depends on the application for which the technology will be used. LED has become the go-to choice for most consumers looking for a new high-definition television, whereas LCD remains a popular choice for touchscreen devices and computer monitors. Regardless, you can’t go wrong with either LED or LCD. They are both two versatile forms of electronic display technology that can deliver incredibly images.

Selecting an ideal video wall solution can be a complex task because of the wide range of options that are available. One of the most important components of a video wall solution is the display type, and the common types that people look at are LCD video walls and LED video walls. Most often than not, it becomes fairly difficult to choose the right one and this article attempts to help you identify the right display type based on your needs.

In the late 1990s, RGB light hit the market and changed the game to LED screens forever. RGB stands for “red, green, and blue”, meaning that with these colors LED lights are capable of producing tens of thousands of different colors and shades. Considering this, LED screens have a bit of an advantage over LCD. Colors are brighter, bolder, and sharper. LCD screens are made out of liquid crystal that has the same volume and density throughout the screen. Additionally, optimal screen brightness of over 12,000 nits (measure for luminance) for outdoor use-cases and large distance viewing is enabled with LEDs.

While power usage is roughly proportional to screen size, LED screens offer greater energy efficiency per pixel than LCDs. This is largely due to LED displays utilizing newer technology, and their ability to dim backlights (such as for absolute black). When dark colors are displayed for a long time, software management has the option to completely turn off the backlight, diminishing the consumption of power even more. LCD screens use more energy since they have to be illuminated at all times to project an image. However, you will still need to make sure your venue has enough power capabilities for both LCD and LED video walls.

When it comes to a video wall solution, LCDs have been the popular option for years, and an ultra-narrow bezel LCD is one of the best suited for the job. LCD stands for “liquid crystal display” and chances are, you use this technology every day with your smartphone. LCD panels in a video display are composed of a layer of liquid crystal that is sandwiched between two polarized pieces of glass. When electricity is applied, the liquid shifts to create an image. Since the crystals in this liquid do not produce their own light, a backlight is created to illuminate the display. LEDs are the most common means of backlighting LCDs, and the technologies are often advertised as a package deal, i.e., “LED-LCD.”

Although LCD video walls are tiled like LEDs, there are spaces in-between the displays known as “bezels.” The ultra-narrow bezel design is the most ideal for video walls because it creates the smallest seams. In fact, with liquid technology and a narrow bezel, video walls can display a highly uniform brightness.

One of the significant differences between LCD and LED displays is the pixel pitch, which is defined as the distance between each pixel. The bigger the pixel pitch is, the further away you have to be to see it clearly. LED video walls have fewer pixels than LCD video walls, so the pixel pitch is greater for LEDs. Typically, LCD displays are installed more frequently than LED displays due to their lower cost and higher resolution when viewed from close distances. However, moving forward, you can expect to see LED video walls more frequently in command centers as both the pixel pitch and price continue to decrease.

Though LEDs have greater pixel pitch and are frequently more expensive, there are some advantages to choosing LEDs over LCDs. LCD displays, though they have greater clarity from a close distance, have bezels that can be seen between the panels of a video wall. The LCD video walls installed have very thin bezels, as thin as 5 or 3mm, but with LED displays you don’t have that visible edge. With a thin bezel, you will still see the lines on an LCD display wall, but with LED there are no visible seams in the wall. The margins in LED displays are smaller, and more facets can be used for a more precise, tight curve when creating curved video walls.

Comparing the hardware of LED and LCD screens to the old-fashioned TV screens is incomparable. The hardware of the latest screens is durable, able to withstand extreme temperatures and physical damage. However, when it comes to software, there are a few potential problems, with the first of them being security.Video walls often display the sensitive content of personal data. Protecting the information has become vital, especially for larger corporations. Getting hacked is every engineer’s nightmare.

Switching cables and outputs all the time is not practical, and even if it did, the hardware couldn’t keep up with the software technology. Hence, many video walls, regardless of whether they are built of LED or LCDs, implement software management to control data sharing and prevent any interruptions and cyber hacks.

LED video walls are much more applicable in indoor applications where ambient light is bright. For example, they can be used in malls, multiplexes, stock tickers, product displays, clubs, and corporate lobbies. They can also be used in all outdoor applications as they are completely weatherproof and viewable under direct sunlight. No other digital medium is more suited for the following purpose: billboards, sports arenas, petrol pumps, or airports. LCD video walls can only be used for indoor applications where display resolution is important, such as control rooms and board rooms.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

Now that we’ve broken down the science, what’s so great about LED lights? Well, their lifetime can last decades in which they do not “burn out” but slowly dim, this is called lumen deprecation. They’re 80-90% more efficient than incandescent bulbs while they also emit brighter light. LEDs are cooler in temperature than incandescent bulbs which reduces combustion. This lower temperature also keeps from adding heat to other electrical components – such as those you’d find in an interactive flat panel display (IFPD). LEDs are also much smaller, so they can be quickly and individually switched while easily customizable into any design.

LCD stands for liquid crystal display. LCDs do not emit light thus they require to be backlit; for CenterStage IFPDs we utilize LCD panels backlit by LEDs.

LCDs are small crystals that exist in their natural, undirected nematic state, or to simply put it, they are twisted strings of crystals. These strings of crystals are responsive to electric currents and changes in temperature, thus the image they form is entirely dependent on the current conducted through them as the voltage dictates the shade of the RGB dots (the three subpixels that make up one pixel).  When electricity is ran through these LCD strings, not only does the voltage determine the shades of the colors, but these twisted strings of crystals change their orientation which then allows light to pass through; this creates the final image displayed on screen.

LED LCDs are the market standard for quality as they have greater longevity, the best resolution, are more energy efficient, lighter in weight, and are the brightest displays in comparison to plasma displays and CCFL LCD panels.

In the HoverCam CenterStage line of IFPDs, we utilize LED backlighting, ensuring lower operation temperatures, quality and longer lifespans and LCD displays to create the most detailed image available on the market. This makes the CenterStage one of the smartest, most quality, and energy-efficient options on the market for an IFPD.

The price of an LED video wall will vary depending on factors like the screen’s size, the product used, and additional installation factors. Our staff is here to provide you with a specific quote for your project allowing you to get an accurate estimate as each installation is unique.

Pixel pitch, which is measured in millimeters, is the center-to-center spacing between the LEDs. When the congregation is closer to the screen, you need a tighter pixel pitch offering a higher resolution screen to avoid pixelation. We determine this based on minimum viewing distance and our team can assist in getting you the correct product & pitch that stays within your budget. To learn more about pixel pitch, visit our LED University page and watch our terminology video.
