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.

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.

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.

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.

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.

"The reason we chose a Full HD(1080p) screen on our new CTL NL81 14” Chromebooks is that in our current work-from-home and distance learning environments, we are all spending a considerable amount in front of our screen, and a FHD screen can be a better experience.” says CTL President Erik Stromquist. "We continue to get user feedback for higher-end capabilities on our Chromebooks, and we are excited to provide the best experience possible while still offering a price that is a great value."

Full HD, or FHD, refers to the image resolution of a display panel. FHD delivers 1080p image resolution and is an impressive step up from the typical High Definition 720p image resolution - about double the pixels to be exact.

All the older TV’s and computer monitors you grew up with had the squarish 4:3 shape– 33% wider than it was high. These are often referred to as square monitors.  4:3 LCD monitors can display analog video signals that conform to NTSC and PAL standards. They are not capable of displaying HD (high-definition) video.

The 4:3 aspect ratio dates back to 1917, when the Society of Motion Picture Engineers adopted it as the standard format for film. In the 1930’s, the television industry adopted the same 4:3 standard. But in the mid-1950’s, the motion picture industry began developing several widescreen formats to improve their decreasing audience numbers. Television broadcasting stayed with the 4:3 standard, until the recent move to HDTV and 16:9 widescreen.

16:9 is the native aspect ratio of most high-definition widescreen LCD monitors and TV’s (16:9 and 16:10 are very similar). It is 78% wider than it is tall, and fully one-third wider than a 4:3 screen. 16:9 widescreen monitors are ideally suited to display HD video signals. Some models can also display SD (standard definition) video signals, but this will require some compromises, as you will read below.

Nearly all experts agree that in order to display optimal video images, it is critical to match the aspect ratio of the monitor to the aspect ratio of the camera (or other incoming video source). Below is a example of a 16:9 image on a 16:9 widescreen lcd monitor:

However, many cameras in the industrial, commercial, security, and law enforcement industries still utilize 4:3 CCD or CMOS imagers. Therefore, to display clear, undistorted video images, it is important to utilize monitors with the same 4:3 aspect ratio to match the cameras. Failure to do so will result in distorted images, as shown below.

Unfortunately, despite the continued widespread use of 4:3 cameras, LCD monitors with a 4:3 aspect ratio are getting harder and harder to find. Many manufacturers have abandoned them in favor of the newer 16:9 widescreens. TRU-Vu Monitors still offers a complete line of industrial-grade 4:3 aspect ratio LCD monitors. These range in size from 5.5″ to 19″ screens. They are available with standard, waterproof, steel or open frame enclosures. They can be touch screen,  sunlight readable, medical-grade, or optically bonded.

16:9 widescreen LCD monitors are the ideal complement to 16:9 format HD cameras. These are increasingly used in video conferencing, broadcast and medical applications. They display superb, distortion-free, high-definition images. TRU-Vu Monitors offers these in 7″, 10.1″, 13.3″, 15.6″, 17.3″, 18.5″ and 21.5″ to 65” LCD screen sizes, in standard, touch screen, sunlight readable, medical-grade, optically bonded and open frame configurations.

You must avoid video images which are stretched, chopped, squeezed, shrunk or distorted. Be sure to choose a LCD monitor with the correct aspect ratio (4:3 aspect ratio or 16:9 aspect ratio) that matches your camera or other incoming video signal.

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.

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

Not sure which one will be best for you? Don’t worry! We’re here to help you figure out the right display for your project or application. In this post we’ll break down the pros and cons of these display types so you can decide which one is right for you.

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

These different technological approaches to display technology have big impact in some features including contrast, brightness, viewing angles, lifespan, black levels, image burn-in, and price.

Everything from the environment your display will be used in, your budget, to the lighting conditions and the required durability will play a part in this decision.

Contrast refers to the difference between the lightest and darkest parts of an image. High contrast will produce sharper images and more easily readable text. It’s a crucial quality for high fidelity graphics and images or to make sure that a message on a display is very visible.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

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.

For screen sizes (typically in inches, measured on the diagonal), see Display size. For a list of particular display resolutions, see Graphics display resolution.

This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g. red indicates a 4:3 ratio).

The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays.

One use of the term display resolution applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pixels creating the display (e.g. 1920 × 1080). A consequence of having a fixed-grid display is that, for multi-format video inputs, all displays need a "scaling engine" (a digital video processor that includes a memory array) to match the incoming picture format to the display.

For device displays such as phones, tablets, monitors and televisions, the use of the term display resolution as defined above is a misnomer, though common. The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920 × 1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not the total number of pixels. In digital measurement, the display resolution would be given in pixels per inch (PPI). In analog measurement, if the screen is 10 inches high, then the horizontal resolution is measured across a square 10 inches wide.NTSC TVs can typically display about 340 lines of "per picture height" horizontal resolution from over-the-air sources, which is equivalent to about 440 total lines of actual picture information from left edge to right edge.

Some commentators also use display resolution to indicate a range of input formats that the display"s input electronics will accept and often include formats greater than the screen"s native grid size even though they have to be down-scaled to match the screen"s parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 × 768 pixel array). In the case of television inputs, many manufacturers will take the input and zoom it out to "overscan" the display by as much as 5% so input resolution is not necessarily display resolution.

The eye"s perception of display resolution can be affected by a number of factors – see image resolution and optical resolution. One factor is the display screen"s rectangular shape, which is expressed as the ratio of the physical picture width to the physical picture height. This is known as the aspect ratio. A screen"s physical aspect ratio and the individual pixels" aspect ratio may not necessarily be the same. An array of 1280 × 720 on a 16:9 display has square pixels, but an array of 1024 × 768 on a 16:9 display has oblong pixels.

An example of pixel shape affecting "resolution" or perceived sharpness: displaying more information in a smaller area using a higher resolution makes the image much clearer or "sharper". However, most recent screen technologies are fixed at a certain resolution; making the resolution lower on these kinds of screens will greatly decrease sharpness, as an interpolation process is used to "fix" the non-native resolution input into the display"s native resolution output.

While some CRT-based displays may use digital video processing that involves image scaling using memory arrays, ultimately "display resolution" in CRT-type displays is affected by different parameters such as spot size and focus, astigmatic effects in the display corners, the color phosphor pitch shadow mask (such as Trinitron) in color displays, and the video bandwidth.

Most television display manufacturers "overscan" the pictures on their displays (CRTs and PDPs, LCDs etc.), so that the effective on-screen picture may be reduced from 720 × 576 (480) to 680 × 550 (450), for example. The size of the invisible area somewhat depends on the display device. Some HD televisions do this as well, to a similar extent.

Computer displays including projectors generally do not overscan although many models (particularly CRT displays) allow it. CRT displays tend to be underscanned in stock configurations, to compensate for the increasing distortions at the corners.

Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon.

Progressive scanning (alternatively referred to as noninterlaced scanning) is a format of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video.

Many personal computers introduced in the late 1970s and the 1980s were designed to use television receivers as their display devices, making the resolutions dependent on the television standards in use, including PAL and NTSC. Picture sizes were usually limited to ensure the visibility of all the pixels in the major television standards and the broad range of television sets with varying amounts of over scan. The actual drawable picture area was, therefore, somewhat smaller than the whole screen, and was usually surrounded by a static-colored border (see image to right). Also, the interlace scanning was usually omitted in order to provide more stability to the picture, effectively halving the vertical resolution in progress. 160 × 200, 320 × 200 and 640 × 200 on NTSC were relatively common resolutions in the era (224, 240 or 256 scanlines were also common). In the IBM PC world, these resolutions came to be used by 16-color EGA video cards.

One of the drawbacks of using a classic television is that the computer display resolution is higher than the television could decode. Chroma resolution for NTSC/PAL televisions are bandwidth-limited to a maximum 1.5MHz, or approximately 160 pixels wide, which led to blurring of the color for 320- or 640-wide signals, and made text difficult to read (see example image below). Many users upgraded to higher-quality televisions with S-Video or RGBI inputs that helped eliminate chroma blur and produce more legible displays. The earliest, lowest cost solution to the chroma problem was offered in the Atari 2600 Video Computer System and the Apple II+, both of which offered the option to disable the color and view a legacy black-and-white signal. On the Commodore 64, the GEOS mirrored the Mac OS method of using black-and-white to improve readability.

In 2002, 1024 × 768 eXtended Graphics Array was the most common display resolution. Many web sites and multimedia products were re-designed from the previous 800 × 600 format to the layouts optimized for 1024 × 768.

The availability of inexpensive LCD monitors made the 5∶4 aspect ratio resolution of 1280 × 1024 more popular for desktop usage during the first decade of the 21st century. Many computer users including CAD users, graphic artists and video game players ran their computers at 1600 × 1200 resolution (UXGA) or higher such as 2048 × 1536 QXGA if they had the necessary equipment. Other available resolutions included oversize aspects like 1400 × 1050 SXGA+ and wide aspects like 1280 × 800 WXGA, 1440 × 900 WXGA+, 1680 × 1050 WSXGA+, and 1920 × 1200 WUXGA; monitors built to the 720p and 1080p standard were also not unusual among home media and video game players, due to the perfect screen compatibility with movie and video game releases. A new more-than-HD resolution of 2560 × 1600 WQXGA was released in 30-inch LCD monitors in 2007.

In 2010, 27-inch LCD monitors with the 2560 × 1440 resolution were released by multiple manufacturers, and in 2012, Apple introduced a 2880 × 1800 display on the MacBook Pro. Panels for professional environments, such as medical use and air traffic control, support resolutions up to 4096 × 21602048 × 2048 pixels).

The following table lists the usage share of display resolutions from two sources, as of June 2020. The numbers are not representative of computer users in general.

In recent years the 16:9 aspect ratio has become more common in notebook displays. 1366 × 768 (HD) has become popular for most low-cost notebooks, while 1920 × 1080 (FHD) and higher resolutions are available for more premium notebooks.

When a computer display resolution is set higher than the physical screen resolution (native resolution), some video drivers make the virtual screen scrollable over the physical screen thus realizing a two dimensional virtual desktop with its viewport. Most LCD manufacturers do make note of the panel"s native resolution as working in a non-native resolution on LCDs will result in a poorer image, due to dropping of pixels to make the image fit (when using DVI) or insufficient sampling of the analog signal (when using VGA connector). Few CRT manufacturers will quote the true native resolution, because CRTs are analog in nature and can vary their display from as low as 320 × 200 (emulation of older computers or game consoles) to as high as the internal board will allow, or the image becomes too detailed for the vacuum tube to recreate (i.e., analog blur). Thus, CRTs provide a variability in resolution that fixed resolution LCDs cannot provide.

As far as digital cinematography is concerned, video resolution standards depend first on the frames" aspect ratio in the film stock (which is usually scanned for digital intermediate post-production) and then on the actual points" count. Although there is not a unique set of standardized sizes, it is commonplace within the motion picture industry to refer to "nK" image "quality", where n is a (small, usually even) integer number which translates into a set of actual resolutions, depending on the film format. As a reference consider that, for a 4:3 (around 1.33:1) aspect ratio which a film frame (no matter what is its format) is expected to horizontally fit in, n is the multiplier of 1024 such that the horizontal resolution is exactly 1024•n points.2048 × 1536 pixels, whereas 4K reference resolution is 4096 × 3072 pixels. Nevertheless, 2K may also refer to resolutions like 2048 × 1556 (full-aperture), 2048 × 1152 (HDTV, 16:9 aspect ratio) or 2048 × 872 pixels (Cinemascope, 2.35:1 aspect ratio). It is also worth noting that while a frame resolution may be, for example, 3:2 (720 × 480 NTSC), that is not what you will see on-screen (i.e. 4:3 or 16:9 depending on the intended aspect ratio of the original material).

The "p-display" nomenclature used in this article refers to the number of pixels displayed across the width of a given phone"s screen. Earlier phones with lower than 720p (lower than HD ready resolution) are not included in this listing. The lists below are dynamic lists and may be sorted into alphabetical order by clicking on the "sort icons" at the top of the first column.

LCD panels" resolutions are often quoted in terms of raw subpixels, misnamed "pixels" in manufacturer"s specifications. Each real pixel includes one subpixel for each of three colors, so calling subpixels "pixels" inflates the claimed resolution by a factor of three. This bit of marketing obfuscation is calculated as horizontal resolution × vertical resolution × 3. For example: 640 × 480 VGA is 921,600 subpixels, or 307,200 pixels, 800 × 600 SVGA is 1,440,000 subpixels, or 480,000 pixels, and 1024 × 768 XGA is 2,359,296 subpixels, but only 786,432 full-color pixels.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

Quad high definition (QHD) is the standard resolution for certain high-end devices like laptops, televisions, and phones. It has a display resolution 2560 x 1440 pixels — or four times that of 720p, hence the name — in a 16:9 aspect ratio.

You may also see WQHD when searching for devices (that stands for "wide quad high definition.") QHD and WQHD are actually the same thing. The "W" is usually meant to signal that it has a 16:9 aspect ratio, since that can be a selling point for manufacturers, despite that the aspect ratio is already a feature of QHD. QHD is also sometimes labeled as 2K or 1440p for marketing reasons. An ultrawide QHD screen expands the horizontal pixels to 3440 and has a 21:9 aspect ratio.

4K, on the other hand, is going to provide a more detailed screen than QHD. The official cinema resolution for 4K screens is 4096 x 2160p, but on a monitor, you will usually see the specs list 3840 x 2160p resolution. So for the average user, it has double the pixels you get with HD.

Again, the higher-resolution option will drain your battery life faster, so you should check out battery life estimates to make sure it works for you. 4K displays are also generally going to cost more than lower-resolution options, so that"s another thing to consider before buying.Devon Delfino is a Brooklyn-based freelance journalist specializing in personal finance, culture, politics, and identity.
