lcd panel va manufacturer

Contrary to what you may think, not all LCD TVs are built around the same core panel technology. They can actually have at their hearts one of two really quite different technologies: VA or IPS.

Each, as we’ll see, has its own distinct advantages and disadvantages – so much so that we personally think the type of panel a particular TV uses should be presented right at the top of its specifications list, rather than typically left off altogether. Especially as some brands have been known to actually mix and match VA and IPS panels at different screen sizes within the same TV series.

The VA initialism stands for Vertical Alignment. This name is derived from the way VA panels apply voltage to vertically aligned liquid crystals that have been mounted perpendicularly to the panel’s glass substrate, making them tilt as required to let the necessary amount of light through for each image frame.

The main advantage of VA panels is contrast. Their perpendicular crystal alignment provides greater control over the light passing through each pixel, meaning dark scenes and dark areas look less grey / enjoy better black levels.

The extent to which this strength is exploited can vary greatly between different manufacturers, and depends on any number of secondary factors. The type and position of LED lighting a particular VA screen might be using can have an impact, for instance. There are multiple variations on the VA theme available from different manufacturers, too. As a basic principle, though, black levels and contrast are consistently and often considerably better on LCD TVs that use VA panels.

Because of their ability to control light better, high-end VA panels generally deliver more brightness in real world conditions than IPS ones do. This further enhances their contrast capabilities, and arguably makes them more consistently able to do fuller justice to the wider light range associated with high dynamic range technology.

Being able to deliver dark scenes with relatively little overlying low-contrast greyness additionally means that VA panels tend to achieve more consistent colour vibrancy and toning.

VA panels for use in LCD TVs come from a number of panel manufacturers, including Samsung Display (which makes a so-called SVA variant) and AU Optronics (which makes an AMVA variant). TV brands are able to buy in panels from these and other VA panel manufacturers as they see fit.

Samsung Electronics is the most consistent user of VA panels in its LCD TVs. In fact, until recently pretty much every Samsung TV at every price level used a VA panel. For the past couple of years, though, IPS panels have unexpectedly cropped up in one or two parts of Samsung’s TV range, including 2021’s high-end QN85 series.

Sony predominantly uses VA panels on its most premium TVs, but it also habitually mixes IPS and VA panels across its wider mid-range and entry level LCD ranges. The same goes for most of the other big brands, too, including Panasonic and Philips.

IPS stands for In-Plane Switching. Like VA panels, IPS panels work by manipulating voltage to adjust how liquid crystals are aligned. Unlike VA, though, IPS panels orient their crystals in parallel with (rather than perpendicular too) the glass substrates present in every LCD panel, and rotate their crystals around to let the desired amount of light through rather than tilting them.

By far the biggest and most talked about advantage of IPS technology is its support for wider viewing angles. In fact, one way of identifying IPS panels has traditionally been to look for quoted viewing angles of 178 degrees.

When we talk about wide viewing angle support in relation to LCD TVs, we’re talking about how much of an angle from directly opposite the screen you can go before the picture starts to lose contrast, colour saturation and, sometimes, brightness.

With VA panels the angle you can watch them before the picture starts to deteriorate sharply can be really quite limited – as little as 20 degrees off axis. While we’d say the 178-degree claims for regular IPS panels are rather exaggerated, you can typically sit at a significantly wider angle than you can with VA and still enjoy a watchable picture.

We’ve even seen occasional evidence of the edges of really big (75-inch plus) VA screens suffering from the technology’s viewing angle limitations when viewed straight on, whereas this never happens with IPS technology.

The VA/IPS viewing angle situation is muddied a little by the introduction into a few high-end VA TVs of wide angle technologies based around filters or sub pixel manipulation. These technologies can be associated with other problems, though, such as reduced resolution, and can still struggle to suppress backlight blooming around stand-out bright objects with LCD TVs that use local dimming backlight systems.

Traditionally IPS panels have been associated with – on high-end screens, at least – wider colour gamuts than VA panels can readily manage. They retain this colour gamut better, too, when viewing the screen from an angle. This is why many professional designers, for instance, have tended to prefer IPS technology to VA. There can be some pretty extreme variance in the range of colour supported across different IPS price points, though, and improvements in premium VA solutions – especially the widespread use of Quantum Dot technologies – have largely evened things up, at least at the premium end of the VA market. In fact, with dark scenes, at least, IPS’s issues with black levels and ‘grey wash’ effect can give good VA panels a colour advantage.

There was a time when IPS technology was considered to have an edge over VA when it comes to response time, leading to less motion blur and improved gaming reaction times. These days, though, we’re seeing pretty much identically low input lag measurements (between 9.4 and 10.4ms) from both VA and IPS TVs.

As with VA, there are different variations on the basic IPS theme made by different panel manufacturers. LG Display is by far the biggest manufacturer of IPS LCD panels for TVs, but AU Optronics also makes them, as well as, more surprisingly, Samsung – though some of the non-LG Display IPS products seem to be more focused on PC monitors than TVs.

Given how dominant LG Display is in manufacturing IPS LCD panels, it’s not surprising to find that pretty much every LCD TV LG Electronics makes features an IPS panel at its heart. Other TV brands that use IPS panels on at least a few of their TVs each year include Panasonic, Philips, Sony and Hisense. In fact, the only big brand that has tended to shun IPS is Samsung (perhaps because of arch rival LG Display’s dominance of the IPS market).

As noted earlier, it can be frustratingly difficult to determine whether a TV is using VA or IPS technology. Sometimes it is mentioned in the specifications list on a manufacturer’s website – but more often it is not.

If you’re able to actually get your hands on an LCD TV, try knocking gently on its screen. If it’s an IPS panel it will feel solid and the picture will only be slightly affected – or completely unaffected – by the impact of your knocks. If it’s a VA panel, the picture will distort quite noticeably around points of impact.

It’s tempting to assume that any TVs with obviously low contrast are IPS while any screen with a narrow viewing angle is VA. As well as depending on having a wide experience of lots of panels, though, there’s just too much variation in the high and low-end fringes of each technology for this approach to be reliable.

Arguably your best bet is to check out a TV model you’re interested in on an industry website called Displayspecifications.com(opens in new tab), which includes usually reliable information on the core panel of pretty much every TV released.

You might want to consider IPS TV if your room layout means one or more viewers regularly find themselves having to watch the screen from a wide angle (though don’t forget that a small number of high-end VA TVs feature wide viewing angle technology). IPS’s black level limitations tend to be less obvious in bright rooms too, if that fits with the sort of environment your TV is likely to be used in for the majority of the time.

Our long experience of testing VA and IPS TVs, though, has led us to conclude that in general, the sort of person most likely to be turning to us for buying advice will be happier with an LCD TV based on VA technology.

VA’s ability to deliver typically much deeper, more convincing black levels and more HDR-friendly contrast helps them deliver a much more consistent and immersive modern AV experience. Especially if you’re the sort of person who likes to dim the lights for serious movie or TV viewing nights.

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

While there are many different manufacturers of LCD monitors, the panels themselves are actually only manufactured by a relatively small selection of companies. The three main manufacturers tend to be Samsung, AU Optronics and LG.Display (previously LG.Philips), but there are also a range of other companies like Innolux and CPT which are used widely in the market. Below is a database of all the current panel modules manufactured in each size. These show the module number along with important information including panel technology and a detailed spec. This should provide a detailed list of panels used, and can give you some insight into what is used in any given LCD display.

Note:These are taken from manufacturer product documentation and panel resource websites. Specs are up to date to the best of our knowledge, and new panels will be added as and when they are produced. Where gaps are present, the detail is unknown or not listed in documentation. The colour depth specs are taken from the manufacturer, and so where they specify FRC and 8-bit etc, this is their listing. Absence of such in the table below does not necessarily mean they aren’t using FRC etc, just that this is how the manufacturer lists the spec on their site.

In both LCD and OLED displays, producing these cells – which are highly complex – is by far the most difficult element of the production process. Indeed, the complexity of these cells, combined with the levels of investment needed to achieve expertise in their production, explains why there are less than 30 companies in the whole world that can produce them. China, for instance, has invested more than 300 billion yuan (approximately $45 billion USD) in just one of these companies – BOE – over the past 14 years.

In order to understand this problem, we first need to know the panel type of LCD. At present, the LCD panels are mainly divided into three categories, which are TN, VA and IPS.

TN panel, full name Twisted Nematic (twist nematic), because the production cost is relatively low, so it is the first popular panel in LCD. The advantage of TN panel is that the response time of GTG panel is very fast, and the gray scale response time of GTG is often up to 1ms, which is the lowest among all LCD panels, so many e-sports / game monitors use TN panel.

However, the shortcomings of the TN panel are also obvious, such as less output gray scale, white color, small visual angle and so on. 1080p is the most common resolution in the TN panel, and there are also some 27-inch QHD panels, and the latest panel can do 28-inch UHD. At present, the main manufacturers of TN panels are Samsung display (Samsung Display), LG, Youda Optoelectronics, Qunchuang Optoelectronics, China Picture Tube and so on.

Let"s talk about the VA panel. VA panel full name Vertical Alignment (vertical arrangement), its advantage lies in the contrast, VA panel is the highest contrast of all LCD panels, usually can reach 3000 VA 1, while the contrast of TN, IPS is only about 1000 VA 1, the intuitive feeling of high contrast is that black looks purer and the picture is more layered.

The gray scale response time of VA panel is faster than that of IPS, and some of them even reach the same 1ms as TN, while the visual angle of TN is much better than that of TN, which is consistent with the visual angle of IPS panel, and there is no light leakage problem of VA panel.

Finally, let"s talk about the IPS panel. IPS full name In-Plane Switching (plane conversion), its advantage is that the color performance is relatively good, and the visual angle is also relatively wide, horizontal and vertical visual angle can reach 178°, but the contrast is not as good as VA panel, and the problem of light leakage is also more prominent.

From the above carding, it is not difficult to see that each panel has its own advantages, but also some inherent shortcomings. For example, TN panel is better than fast response time, but the color and visual angle is not good; VA panel contrast is high, but there are still some differences in response time and color; IPS color is good, but there are long response time and light leakage problems.

So which panel to choose depends on the specific requirements, you can"t simply think that IPS must be better than VA, or VA must be better than TN. For example, heavy players of FPS games who value response time can choose the display of TN panel, designers who value visual angle and have certain requirements for color can choose the display of IPS panel, and friends who like to watch some high-contrast and more powerful pictures can choose the display of VA panel.

In general, Vertical Alignment refers to the positioning of the liquid crystals in between two polarising filters. Depending on the direction the crystals are facing, they let backlight either pass through or block out in a different way. VA technology was discovered already in the early 1970s. Around twenty years later, the Japanese company Fujitsu made VA panels marketable and since then, the monitors have steadily improved. There are several elements that are important for your choice of the perfect gaming display.

Image quality:IPS monitors come with the largest colour gamut and offer the richest image quality on the market. In the past, VA panels trailed behind and could not convince with their display of colours.

Nowadays, as the technology is being further researched and improved, VA panels are right in the middle between IPS and TN. Their colour reproduction can offer a great experience, as they start with full sRGB coverage as minimum. The best products on the market can easily achieve 85 and 90% DCI-P3 coverage. Most of AOC’s models feature 16.7 Million display colours which are more than enough to create an immersive, life-like experience.

VA panels excel at a deep contrast ratio and are far beyond in the LCD technology. Dark scenes are portrayed in a rich black, while IPS for comparison can only achieve a grey shade. Usually, VA panels have a contrast ratio ranging from 3000:1 to 6000:1, whereas IPS mostly reaches a ratio of 1000:1.

Viewing angle:The viewing angle describes at which angle you can look at your monitor and still experience good image quality. When the first VA panels were manufactured in 1971, the angle was quite narrow and did not allow viewers to move their position. Thanks to further development, the viewing angle could be increased steadily and in the 1990s, the VA was finally ready for commercial use.

Not only are VA panels affected by such issues. A VA monitor for example will lose its saturation level when looking from a side angle, whereas IPS will lose luminosity. Nowadays, the viewing angle of VA panels has been drastically improved, being between the quality of TN and IPS panels. When used as a gaming monitor only, the angle does not even have any noticeable effect and just plays a role when used as a TV display. Nonetheless, AOC’s VA panels come with a 178/178 º viewing angle, so you can comfortably spectate the action on screen from any direction.

Refresh rate:The refresh rate of a monitor specifies how many frames per second a display computes. The value of this rate is measured in Hertz, which shows the number of times per second an image gets updated. One image per second equals 1 Hz, therefore the higher the amount, the smoother your image quality.

With a standard of 60Hz, VA panels offer a solid refresh rate that enables you to play all your games fluently. While 60 Hz are a rather average value in the realm of gaming monitors, there are also VA screens on the market that reach way higher numbers. As an example, the AOC C32G2ZE/BK boast outstanding 240 Hz which guarantee flawless action on-screen.

While VA panels impress with their flawless contrast, they come with a slightly higher response time than TN and IPS by default. The higher the response time, the greater the risk for motion blur. VA used to be on the lower end with an average of 5 ms. However, the technology gets constantly developed to reach the best standard possible. Therefore, an older low-end model might come with a noticeable blur. Later monitors boast a faster response time. Most of AOC’s VA models are designed with super-fast 1 ms MPRT, guaranteeing smooth, fast-moving action. The C27G2ZU/BK takes the crown by reducing the response time even further to super-sonic 0.5 ms.

VA have long redeemed themselves from being second choice to an outstanding option on the monitor market. VA is the middle ground between TN and IPS panels, combining their advantages and therefore a rock-solid choice no matter what you intend to use your display for. If you are an avid movie fan or indulge into darker, high-contrast video games, a VA panel would be the perfect monitor.

But if you tend to play colourful titles and want the widest viewing angle, you can also go for an IPS monitor.

Many TVs use LCD (Liquid Crystal Display) panels that are lit by LED backlights. There are two popular types of LCD panels: In-Plane Switching (IPS) and Vertical Alignment (VA), and there are two main differences between each type. A VA panel usually has a high contrast ratio and narrow viewing angles. However, an IPS panel has low contrast and wide viewing angles. These are the main differences between each, and for the most part, panel type doesn"t affect other aspects of picture quality, like peak brightness, color gamut, or color accuracy.

For the purposes of this article, we"re going to compare two LED-backlit LCD TVs: the Sony X800H, which has an IPS panel, and the Hisense H9G, which has a VA panel. Due to their different panel types, there are three noticeable differences in picture quality: viewing angles, contrast, and black uniformity, so we"re going to look at each one.

Viewing angle refers to the angle at which you can watch the TV without seeing a noticeable drop in picture quality. IPS TVs are the clear winner here, as the image remains accurate when viewing from the side - you can see the differences in the videos above. This is their main advantage over VA panels. Most VA panel TVs have a noticeable loss in image accuracy when viewing from the side. The narrow viewing angle of VA-type TVs is also problematic when the TV is used as a PC monitor from up close since the edges of the display look washed out.

VA panels are far superior to IPS panels when it comes to this, so if you tend to watch movies in the dark, you likely want to get a TV with a VA panel. Most TVs use VA panels due to this main advantage, and high-end models may have a local dimming feature that further enhances black levels. On the other hand, IPS panels normally have low contrast, so blacks look closer to gray, but you may not notice the difference in contrast in bright environments.

Our black uniformity tests determine how well a TV displays a dark scene with a bright image in the center. Ideally, you want to see a completely black screen with the center cross being the only part that"s lit up, and this is important for people watching movies. No LED TV has perfect uniformity, and unlike viewing angles and contrast, the panel type doesn"t completely determine its black uniformity. However, most VA panels that we"ve tested have good black uniformity, while most IPS panels have sub-par black uniformity. This doesn"t mean that every VA panel TV has good uniformity, as this can change between units, and you can also improve uniformity using the local dimming feature.

LCDs function by having liquid crystals in little groups to form the pixels. These crystals react and change position when charged with electricity and, depending on their position, they allow a certain color of light to pass through.

IPS displays have their crystals aligned horizontally at all times. When charged, they turn to allow light through. VA displays have their crystals aligned vertically. When charged, they move to a horizontal position, allowing light through. When current isn"t sent through them, however, their vertical alignment blocks light far more efficiently, creating better blacks and giving better contrast.

There"s also another type of IPS panel, called Plane-to-Line Switching (PLS), which can be seen with the Sony X800H. This panel type was designed by Samsung and technically performs the same as an IPS panel. When you compare the pixels visually, IPS panels look like chevrons, VA looks like very straight rectangles, and PLS looks like round-edged capsules. You can learn more about pixels here.

The way the pixels are laid out can also affect text clarity. Many IPS panels, like the ones on the Sony X800H or the LG SK9000, use RGB sub-pixel layouts, while many VA panels have a BGR layout, like on the Hisense H9G. The sub-pixel layout doesn"t directly affect picture quality unless you"re using it as a PC monitor. Some applications may expect an RGB layout, so if you have a BGR sub-pixel layout, text may not look clear. You may need to increase the text scaling to read it properly, but this issue isn"t common with an RGB layout. You can learn more about it here.

Unlike LED TVs, OLEDs don"t use a backlight and instead have self-emitting pixels. This allows the pixels to individually turn on and off, resulting in perfect blacks. This means that they also have perfect black uniformity as there"s no blooming around bright objects like on some LED TVs. They also have wide viewing angles, sometimes even wider than some IPS panels, so OLEDs are a good choice for wide seating arrangements.

However, the one major downside to OLEDs compared to LEDs is their risk of permanent burn-in. This could be problematic if you constantly watch content with static elements, like the news, or if you use it as a PC monitor. We don"t expect it to be an issue for people who watch varied content, but if you"re truly worried about it, LED TVs appear to be immune to burn-in.

Samsung released quantum dot TVs in 2015, which they later labeled as QLED in 2017. These TVs include a quantum dot layer between the LED backlights and the LCD panel to achieve a wider color gamut. Other companies like Vizio and TCL also use this quantum dot technology on their TVs. Adding this extra quantum dot layer doesn"t change the characteristics of the panel type; the VA panel on the TCL 6 Series/S635 2020 QLED still has a high contrast ratio and narrow viewing angles. Although most QLED TVs use VA panels, you can easily use an IPS panel as well.

Manufacturers have tried different techniques to improve the viewing angles on VA panels over the years, aiming to produce a perfect LCD panel with both wide viewing angles and high contrast. While they have yet to achieve that goal, a few TVs have hit the market that try to combine the best of both panel types. The first TVs with this viewing angle technology came out in 2018, and only a few high-end models like the Samsung Q90/Q90T QLED and the Sony X950H had this technology in 2020. These TVs are a bit unique, delivering noticeably better viewing angles than their pure VA counterparts, but still worse than true IPS panels. This comes at the expense of a lower contrast ratio, as these TVs have worse native contrast than most VA panels, but they"re still better than IPS panels. Combined with their local dimming features, they still produce deep blacks.

Between IPS and VA panels, neither technology is inherently superior to the other as they both serve different purposes. In general, IPS TVs have wide viewing angles suitable for when you want to watch the big game or your favorite show in a large seating arrangement. They"re also beneficial for use as a PC monitor since the edges remain accurate if you sit up close. However, VA panels are a better choice for watching content in dark rooms, as their improved contrast allows them to display deep blacks. Choosing between the two is a series of trade-offs and qualities, so choosing the best TV for your needs depends on your usage.

Again, IPS is the clear winner here. The vertical viewing angles are very similar to the horizontal ones on both IPS and VA panels. Unfortunately, this is one area where TN panels are usually much, much worse. TN monitors degrade rapidly from below, and colors actually inverse - resulting in a negative image that can be distracting. For this reason, if you decide to buy a TN monitor, look for one with an excellent height adjustment, or consider buying a VESA mounting arm, as you should mount TN monitors at eye level. Even when mounted properly, larger TN displays can appear non-uniform at the edges.

There"s usually not much difference between VA and IPS panels in terms of gray uniformity. It"s rare for monitors to have uniformity issues, and even on monitors that perform worse than average, it"s usually not noticeable with regular content. TN monitors tend to perform a bit worse than usual, though, and the top half of the screen is almost always darker than the rest, but that"s an artifact of the bad vertical viewing angles.

Black uniformity tends to vary significantly, even between individual units of the same model, and there"s no single panel type that performs the best. It"s rare for monitors to have good black uniformity, and almost every monitor we"ve tested has some noticeable cloudiness or backlight bleed. IPS and TN panels can look slightly worse due to their low contrast ratios, as the screen can take on more of a bluish tint when displaying dark scenes. Like with contrast, black uniformity issues usually aren"t very noticeable unless you"re looking at dark content and you"re in a dark room. If you only use your monitor in a bright environment, generally speaking, you don"t need to worry about black uniformity.

Historically, TN panels used to have the worst colors, as many of them were cheaper models that only supported 6-bit colors or used techniques like dithering (FRC) to approximate 8-bit colors. Most displays today, including TN models, are at least 8 bit, and many of them are even able to approximate 10-bit colors through dithering. New technologies, like LG"s Nano IPS and Samsung"s Quantum Dot, add an extra layer to the LCD stack and have significantly improved the color gamut of modern IPS and VA displays, leaving TN a bit behind. Between them, NANO IPS is slightly better, as it tends to offer better coverage of the Adobe RGB color space. Although the difference is minor, IPS panels still have a slight edge over VA and TN displays.

Although TN panels have caught up a bit in the SDR color space, they"re far behind when it comes to HDR, so if you"re looking for a good HDR color gamut, avoid TN panels. Between VA and IPS panels, the difference isn"t as significant; however, IPS panels still have a slight edge. The best VA panels top out at around 90% coverage of the DCI P3 color space used by most current HDR content. IPS panels go as high as 98% coverage of DCI P3, rivaling even some of the best TVs on the market. Due to the very high coverage of DCI P3 on both VA and IPS, the difference isn"t that noticeable, though, as most content won"t use the entire color space anyway.

Although not necessarily as noticeable to everyone as the differences in picture quality, there can also be a difference in motion handling between IPS, VA, and TN displays. TN panels historically offered the best gaming performance, as they had the highest refresh rates and extremely fast response times. Manufacturers have found ways to drastically improve the motion handling of VA and IPS panels, though, and the difference isn"t as pronounced.

LCD panel technology has changed drastically over the last few years, and the historical expectations for response time performance don"t necessarily hold anymore. For years, TN monitors had the fastest response times by far, but that"s started to change. New high refresh-rate IPS monitors can be just as fast.

VA panels are a bit of a strange situation. They typically have slightly slower response times overall compared to similar TN or IPS models. It"s especially noticeable in near-black scenes, where they tend to be significantly slower, resulting in dark trails behind fast-moving objects in dark scenes, commonly known as black smear. Some recent VA panels, such as the Samsung Odyssey G7 LC32G75T, get around it by overdriving the pixels. It results in much better dark scene performance but a more noticeable overshoot in brighter areas.

Within each of the three types of LCD we mentioned, other related panel types use the same basic idea but with slight differences. For example, two popular variants of IPS panels include ADS (technically known as ADSDS, or Advanced Super Dimension Switch) and PLS (Plane to Line Switching). It can be hard to tell these panels apart simply based on the subpixel structure, so we"ll usually group them all as IPS, and in the text, we"ll usually refer to them as IPS-like or IPS family. There are slight differences in colors, viewing angles, and contrast, but generally speaking, they"re all very similar.

There"s another display technology that"s growing in popularity: OLED. OLED, or organic light-emitting diode, is very different from the conventional LCD technology we"ve explored above. OLED panels are electro-emissive, which means each pixel emits its own light when it receives an electric signal, eliminating the need for a backlight. Since OLED panels can turn off individual pixels, they have deep, inky blacks with no blooming around bright objects. They also have excellent wide viewing angles, a near-instantaneous response time, and excellent gray uniformity.

OLED panels aren"t perfect, though. There"s a risk of permanent burn-in, especially when there are lots of static elements on screen, like the UI elements of a PC. There aren"t many OLED monitors available, either, but they"ve started to gain popularity as laptop screens and for high-end monitors, but they"re very expensive and hard to find. They"re also not very bright in some cases, especially when large bright areas are visible on screen. The technology is still maturing, and advances in OLED technology, like Samsung"s highly-anticipated QD-OLED technology, are promising.

As you can probably tell by now, no one panel type works best for everyone; it all depends on your exact usage. Although there used to be some significant differences between panel types, as technology has improved, these differences aren"t as noticeable. The two exceptions to this are viewing angles and contrast. If you"re in a dark room, a VA panel that can display deep blacks is probably the best choice. If you"re not in a dark room, you should focus on the other features of the monitor and choose based on the features that appeal to your exact usage. IPS panels are generally preferred for office use, and TN typically offers the best gaming experience, but recent advancements in VA and IPS technology are starting to change those generalizations. For the most part, the differences between each panel type are so minor now that it doesn"t need to be directly factored into your buying decision.

When buying a TV with LED technology, we can find different screen technologies. Choosing a TV with one type of screen or another is a factor that will influence the image quality significantly. Mainly two types of panels are manufactured: IPS and VA panels. As we will see now, depending on the use you are going to give to your TV, you may be more interested in a TV with VA panel or IPS panel.

Next, we are going to explain the differences between IPS panels and VA panels. In this way, we hope to help you choose the best TV for your particular use.

First of all, comment that the name IPS comes from the fact that the liquid crystals of the panel are aligned horizontally (In-Plane Switching). These crystals are parallel to the glass substrates allowing the orientation to be changed by rotating the liquid crystal molecules in the same plane.

This is the technical explanation, but the interesting thing is to know, what performance this type of panel is going to give us and what pros and cons it offers.

An IPS panel offers as a great advantage, wide viewing angles. This means that even if the TV is viewed from a side angle, contrast and color are maintained.

Some IPS panels offer lossless viewing angles up to 178°. Thanks to this, a TV with an IPS panel can be viewed correctly from the sides. The good thing about this is that color saturation and contrast will remain almost lossless when viewed from the side.

So, you may be interested in buying an IPS panel TV if you are going to watch it from different points or if you are several in the family and there are some of you who watch the TV from a more foreshortened position.

Their response time is usually somewhat lower than those offered by VA panels. The time it takes for the pixels to change is somewhat less and they can deliver moving images with a little more clarity.

As weaknesses, their contrast is usually quite low. The contrast values of any IPS panel are always poorer than those offered by a VA panel. In this type of panels, the black level achieved is very low and are usually dark grays instead of blacks.

The black level, however, can be improved in Full Array TVs with Local Dimming and in Mini LED models. The models with this system use more LED bulbs and with the possibility of adjusting the illumination by zones, achieving better black values. The downside is that as a general rule, IPS panels tend to have more light leakage problems than VA panels, although this varies from unit to unit and the type of backlight used.

Generally, they are not the best choice for movie buffs as a lot of information is lost in dark scenes. Compared to a VA panel, this problem is noticeable.

It is also common, that they have more reflections compared to VA, although this depends on each model and if it includes any added filter to reduce reflections.

IPS panels are widely used in monitors, thanks to what we have said about their better response time and better color reproduction and are especially recommended for photo editing.

The main manufacturer of IPS panels is LG. Some Sony and Panasonic models carry IPS panels, and these are mostly manufactured by LG Display. Although recently LG announced that it was cutting back on LCD panel manufacturing.

Within IPS panels there are different variants with different names but which are based on the same concept and obtain very similar performance. The best known are the PLS and ADS panels, which are mounted in some current Samsung TVs.

Unlike an IPS panel, a VA type panel has an alignment of liquid crystals in a vertical plane to the glass substrate and which tilt when a voltage is applied to let light through.

VA panels achieve much higher contrasts than IPS panels. Their major advantage is the reproduction of deep blacks and better detail in shadow areas, so that not as much information is lost as in IPS type displays.

The contrast levels of a VA panel, can be up to 300% higher than that of an IPS panel. The black tones it achieves are always much deeper. This is very noticeable in dark scenes in movies. Therefore, it is the best choice for moviegoers.

However, new versions of these panels are being produced and the angles are improving, especially in the high end, and in some cases are equal to the angles offered by IPS.

The main manufacturer of VA panels was Samsung and their own TVs mainly mounted panels manufactured by themselves. However, like LG, they have greatly reduced production and it is now very common for them to carry panels from other manufacturers such as BOE, AUO, etc.

The other manufacturers such as Sony and Panasonic have long since stopped making panels and carry panels made by companies such as Chi Mei, Sharp or AUO. In any case, the fact that a brand does not produce its own panels, does not mean in any case, less image quality.

We leave you with a summary of the advantages offered by each type of panel for you to value which is the option that suits you best according to the use you give to the TV.

Here the winner is IPS panels by offering better viewing from extreme angles. Colors and contrast are best maintained when viewed at angles greater than 35°..

In VA screens, there is usually a loss of contrast quite pronounced from about 35-40 ° looking a more washed out image. Also the colors begin to lose saturation and flatten out, losing detail in the colors and looking more uniform.

Anyway, there are some TVs with VA panel, which incorporate a filter that improves the viewing angle. An example is the Samsung’s top-of-the-line QLED models. and the X95K and Z9K from Sony.

In summary, especially in the low and mid ranges IPS panels provide a better side view than VA panels, so they are better if you view them from different points.

The winner in this field is VA panels. The contrast is much higher than that offered by IPS panels, which are far inferior in this respect. Blacks tend to be purer on VA panels than on IPS panels.

The difference between IPS and VA panels is usually quite noticeable in this aspect reaching up to 300% in some cases. Therefore, they are always much more recommendable for users who like movies.

In the contrast variant, the brightness level also comes into play. In this aspect, an IPS or VA panel can reproduce a similar brightness, but having a better black level, the contrast ratio of a VA panel is usually much higher than that provided by an IPS.

It is unusual for burn-in or retentions to occur on LCD displays whether they are IPS or VA type. This problem occurs when an image is left static for a prolonged period of time. However, the risk is higher for IPS type displays.

VA panels are more recommended for watching movies and series in dark rooms and in a location that is quite in front of the TV. They give us the highest contrast values and allow us to see better details in the dark parts of the image. Also, although it depends on each specific model, they usually have less reflections.

IPS panels on the other hand, are the best option, if the location from where you sit is not fully frontal to the TV and you usually watch it in a brightly lit room. Colors and contrast are maintained with less variation when viewed from the sides.

LG2022 models2021 modelsQNED96, QNED91, QNED86, QNED80: VA or IPS depending on inchAll the range mounts IPS panel except in 50 and 70 inches which is VA.

As you can see, each type of panel has its advantages and disadvantages. With this comparison, hopefully the differences between IPS and VA panels are clear to you. Moreover, these panels are not only found in televisions, but are also manufactured for monitors and cell phones.

For viewing in dark or very dimly lit rooms, the best choice is a TV that mounts VA screen, as it will provide better blacks as well as less blooming and light leakage.

If in your case you are going to be viewing the TV from a fairly foreshortened angle, IPS panels are going to offer you a better angle than VA panels. The colors will maintain better saturation as well as the contrast will be maintained, making the picture look less washed out.

As we have seen, it depends on each situation, but generally in the absence of assessing other important aspects such as the image processor, refresh rate, etc., we recommend a TV with VA panel. They are the most recommended for watching movies and series due to their better contrast and detail in the dark parts.

Recently, TVs with Mini LED technology have been launched, which still use an LCD panel with backlighting by LED bulbs, but now the size of these is much smaller. In this way, they can have many more bulbs, so that the backlighting is more accurate, improving blacks and reaching a higher peak brightness. In this last aspect of brightness, Mini LED TVs are superior to OLED models.

Vertical alignment (VA) is a type of LCD panel technology that when no electric current is running through, enables liquid crystal cells to naturally align vertically between two substrate panes of glass, blocking the transmission of light from the backlight.
