lcd panel vs ips quotation

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.

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.

Display technology has been evolving for more than a century and continues to drive innovations in the electronic device market. IPS technology was developed in the 90s to solve color and viewing angle issues.

IPS display panels deliver the best colors and viewing angles compared to other popular display planes, including VA (vertical alignment) and TN (twisted nematic).

LCDs (liquid crystal displays). IPS changes the behavior of an LCD’s liquid crystals to produce a sharper, more accurate picture. This technique allows IPS displays to deliver a higher quality viewing experience than other screen types like TN or VA.

IPS acts on the liquid crystals inside an LCD, so when voltage is applied, the crystals rotate parallel (or in-plane), allowing light to pass through them easily. By reducing the amount of interference in the light being produced by the display, the final image on the screen will be much clearer.

One of the leading advantages that IPS offer is its ability to deliver wide angles while preserving colors and contrast. This means you can view an IPS screen from nearly any angle and get an accurate representation of the image on-screen.

IPS display screens and monitors offer the best quality in different environments (direct sunlight, low light, indoors, or outdoors) compared to TNs or VAs.

IPS LCDs require about 15% more power than a standard TN LCD. OLED displays require much less power than IPS types due to the fact that they don’t require a backlight. The LCD IPS technology is not the ideal solution if you need an energy-efficient display. You’re better off choosing an OLED or TN TFT for a low-power solution.

Because of the newer and more advanced technology found in IPS displays, they’re more expensive to manufacture. For a more cost-effective solution, a TN LCD would be a better choice.

IPS displays provide a huge boost to viewing angles and color reproduction, but they don’t have the same contrast capabilities as some other competing display types. OLED displays are able to deliver true black by shutting off their active pixels completely, resulting in much higher contrast than IPS displays. If you’re looking for maximum contrast in your display, you’re better off with an OLED display.

Because of in-plane switching’s ability to boost viewing angles and retain color accuracy, it allows LCDs to compete with the high contrast images found on OLED displays.

If you don’t require the highest refresh rates and don’t mind slightly higher power consumption, then an IPS display will greatly benefit your project.

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.

Whether to pick a VA (Vertical Alignment) panel or IPS (In-Plane Switching) panel depends on your intent. These two panels have two primary differences. VA offers a high contrast ratio with limited viewing angles, while IPS comes with a lower contrast but wider viewing angles.

Both these panels have their highs and letdowns. The most straightforward way to determine your pick is by deciding which attributes are the most important for you.

If you need a monitor for competitive gaming, or a monitor for office work, etc., it might be a bit challenging to decide. Fortunately, I will take you through what to expect from them, having tested various VA and IPS panels myself.

Key TakeawaysYour purpose will determine whether you choose an IPS (In-Plane Switching) panel or a VA (Vertical Alignment) panel. There are two main distinctions between these two panels

Image quality is a broad topic that encompasses multiple details. I will focus on the colors that IPS and VA panels have, how the two panels contrast light and dark areas, and the viewing angle of the two panels.

I love IPS panels because they have one of the highest color gamut performances, much higher than VA panels. For this reason, IPS panels display a game"s graphics better than VA panels. These screens represent the graphics of your games more realistically and 40 inch 4K monitors are now top of the range.

An IPS gaming monitor provides wide viewing angles that offer sharp pictures even when sitting a bit far from your screen (see our Acer XR382CQK review). As I enjoy multiplayer games with pals, sitting away from the screen while getting a great picture quality is something I consider crucial in winning demanding titles.

What I least like about IPS displays is that they typically have a lower refresh rate than 75Hz. Being unable to play the most action-packed games with a higher frame rate is a bummer to most enthusiasts.

VA monitors may not offer you a TN panel"s performance as well. And while I may not like the average refresh rates of IPS monitors, VA panels are a bit more restrictive when it comes to supported games.

While low response times are common in IPS panels, most IPS gaming monitors have about four milliseconds. This level is not much of a problem for most games. However, I"m not too fond of it when playing racing and fast shooter games because of ghosting.

A VA panel is slightly slower than an IPS panel. Therefore, you will notice slightly more motion blur when playing your games. Like IPS panels, some options offer you a one-millisecond response time for image sharpness.

If you need a monitor with an amazing contrast ratio, look into VA panels. And with the provision of VA monitors with a slower response time, you can find screens that offer a good gaming experience in most games.

Different Liquid Crystal Display (LCD) panel types have their advantages and disadvantages, and selecting an IPS vs VA TV depends on what use you have in mind. So, which of these panels should you use for movies?

IPS TVs have a better viewing angle than their VA counterpart. Their image accuracy remains fairly high even when I"m watching my movies from the side.

VA panels have better contrast ratios between the two panels. I like their deep blacks when watching movies in the dark. If you geek over late-night shows, go for VA as it provides more definition.

IPS TVs generally have lower contrast. When using them, I tend to see blacks displayed as gray because of IPS glow. However, the difference is hardly noticeable in brightly lit conditions.

Unlike contrast and the viewing angle, the panel type doesn"t exclusively dictate a screen"s black uniformity. Regardless, most of the VA panels I use have better black uniformity between the two panels.

This doesn"t immediately paint VA panel TVs as the winner, and you may find a better-displaying IPS. Besides, you can enhance the screen"s uniformity using the dimming function.

Displays with great color accuracy and extensive coverage of wide color gamuts like DCI-P3 or Adobe sRGB are typically made using IPS panels. You don"t necessarily need to gaze directly at an IPS monitor in order to see realistic colors because IPS displays typically appear beautiful from wider angles as well.

VA panels have completely adequate color accuracy and coverage for the great majority of users, despite the fact that IPS is typically superior to VA in these areas. A VA monitor that only covers 90% of the DCI-P3 color space is actually a very good amount of coverage for games and content consumers, with the exception of professional picture and video editors.

LCD panels function using liquid crystals which, when charged with electricity, react and change location. Based on the position, the crystals display a particular color.

When IPS displays get charged, their crystals let light through by aligning horizontally. Without current, this vertical alignment (click here for best vertical monitors) efficiently bars light and offers deeper blacks.

PLS (Plane-to-Line Switching) is a type of IPS used on Samsung monitors (check out also Benq monitors) which perform similarly but with round-edged pixels. On the other hand, VA pixels appear like straight rectangles.

IPS panels have an RGB sub-pixel arrangement, whereas numerous VA panels feature a BGR layout. The sub-pixel layout doesn"t outrightly affect image quality, provided it"s not a PC monitor.

Some applications require an RGB arrangement. When I use a BRG VA panel in such cases, I see some slight blurriness on the text. However, adjusting my text scaling eases readability. Overall, RGB layouts don"t have this issue as much as BRG.

The majority of IPS panels offer viewing angles up to 178 degrees horizontally and vertically. Accordingly, if you"re viewing content off-center, you won"t notice much color shifting or a noticeable decrease in picture quality until you get to the very edges of the viewing angles.

Even though VA panels have improved significantly over the years in terms of viewing angles, they still fall short of IPS panels in some respects. When viewing content off-center, VA panels are often a little weaker in terms of color/contrast shifts. This is probably less of an issue for gamers, who are more likely to be seated directly in front of the monitor and not move around the monitor"s ideal viewing angle.

You"ll notice that manufacturers are trying out multiple techniques to enhance VA viewing angles while achieving a high contrast. Although this goal is a work in progress, several TVs are now available that try to encompass both these crucial attributes.

The first sets to feature a broad viewing angle got announced in 2018. Several pricey models also came out with this technology in 2020, for instance, the Sony X950H and the Samsung Q90/Q90T QLED (see our Quantum Dot vs IPS post).

While I love their recognizable improvement in viewing angles over pure VA TVs, they are still yet to achieve the level of performance you get with a pure IPS panel.

As they solve one problem, the upgraded VA panels present you with another issue. Options like the Sony X950H have noticeably lower contrast ratios than typical VA panels.

Nevertheless, I appreciate their native contrast still being higher than regular IPS panels. With their dimming feature, I still can get a deep black convenient for night movies.

Neither panel technology is inherently better because they have different functions. IPS displays are suitable for watching big games or a show across a wide sitting arrangement.

Selecting between the two panels means you"ll give up particular features. Depending on your movie needs, I believe you can decide which panel suits you.

You probably now know the most suitable panel to get, given the different specifications. As in most instances, the higher your budget (see the best budget picks), the better the panel. Here is a simple guide on the ideal panel depending on your usage:

Editing footage and pictures:IPS monitors are more favorable given their better color reproduction. Some VA panels offer wide color ranges, though they typically have motion blur

IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane). The molecules are reoriented by an applied electric field, whilst remaining essentially parallel to the surfaces to produce an image. It was designed to solve the strong viewing angle dependence and low-quality color reproduction of the twisted nematic field effect (TN) matrix LCDs prevalent in the late 1980s.

The TN method was the only viable technology for active matrix TFT LCDs in the late 1980s and early 1990s. Early panels showed grayscale inversion from up to down,Vertical Alignment (VA)—that could resolve these weaknesses and were applied to large computer monitor panels.

Shortly thereafter, Hitachi of Japan filed patents to improve this technology. A leader in this field was Katsumi Kondo, who worked at the Hitachi Research Center.thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.Super IPS). NEC and Hitachi became early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remain the dominant LCD designs through 2006.

IPS technology is widely used in panels for TVs, tablet computers, and smartphones. In particular, most IBM products was marketed as CCFL backlighting, and all Apple Inc. products marketed with the label backlighting since 2010.

Most panels also support true 8-bit-per-channel colour. These improvements came at the cost of a lower response time, initially about 50 ms. IPS panels were also extremely expensive.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

In this case, both linear polarizing filters P and A have their axes of transmission in the same direction. To obtain the 90 degree twisted nematic structure of the LC layer between the two glass plates without an applied electric field (OFF state), the inner surfaces of the glass plates are treated to align the bordering LC molecules at a right angle. This molecular structure is practically the same as in TN LCDs. However, the arrangement of the electrodes e1 and e2 is different. Because they are in the same plane and on a single glass plate, they generate an electric field essentially parallel to this plate. The diagram is not to scale: the LC layer is only a few micrometers thick and so is very small compared with the distance between the electrodes.

Unlike TN LCDs, IPS panels do not lighten or show tailing when touched. This is important for touch-screen devices, such as smartphones and tablet computers.

Toward the end of 2010 Samsung Electronics introduced Super PLS (Plane-to-Line Switching) with the intent of providing an alternative to the popular IPS technology which is primarily manufactured by LG Display. It is an "IPS-type" panel technology, and is very similar in performance features, specs and characteristics to LG Display"s offering. Samsung adopted PLS panels instead of AMOLED panels, because in the past AMOLED panels had difficulties in realizing full HD resolution on mobile devices. PLS technology was Samsung"s wide-viewing angle LCD technology, similar to LG Display"s IPS technology.

In 2012 AU Optronics began investment in their own IPS-type technology, dubbed AHVA. This should not be confused with their long standing AMVA technology (which is a VA-type technology). Performance and specs remained very similar to LG Display"s IPS and Samsung"s PLS offerings. The first 144 Hz compatible IPS-type panels were produced in late 2014 (used first in early 2015) by AUO, beating Samsung and LG Display to providing high refresh rate IPS-type panels.

Your gaming monitor is one of the most important parts of your PC, and a big part of that is down to the type of panel it uses to display all those lovely polygons. You"ve probably seen lots of different monitor panel types crop up in a gaming screen"s specs sheet, too: words like TN, IPS and VA. But what do they actually mean, and how do they affect the quality of your gaming monitor? Well, as you"ve probably guessed from the title up top there, I"m going to tell you everything you need to know about all the different gaming monitor panel types, including their strengths, weaknesses and which one you should look to buy if you want the best possible image quality.

Now, I"m going to warn you - most of what you"ll read below is all going to be pretty general. Not all panel types behave the same way, for example, and there will always be some that outperform the rest. That"s why it"s still important to read proper reviews of gaming monitors so you can get an accurate picture of how a monitor"s panel type stacks up against the rest.

I"m also not going to spend ages talking about the exact chemical structure of every single type of sub-pixel, because, well, there are plenty of other people who have done that already. If you"re after that kind of detail, I"d suggest heading over to the folks at TFT Central. Instead, I"m going to be concentrating on what you actually need to know about gaming monitor panel types, such as how their various characteristics affect their performance, and how you can avoid falling into monitor misery by making sure you know exactly what specs sheets are talking about when they start throwing a million acronyms at you. So let"s get to it.

Let"s start with one of the most common monitor panel types available today: TN, or Twisted Nematic. TN panels are what you"ll find in most gaming monitors these days, especially ones with high refresh rates and those geared toward competitive esports and the like.

The good: That"s because they"re a) generally quite cheap to make and b) have the fastest response times out of all the different panel types. This means there"s less lag between you clicking your mouse or tapping your keyboard and that action being translated onscreen, making them ideal for twitchy shooters and games that need fast reaction times.

The bad: Alas, the disadvantage of picking a TN panel is that they generally don"t have the best colour accuracy and they also have quite narrow viewing angles. The former isn"t the case for every TN screen - those certified by Nvidia for use in their G-Sync gaming monitors, for instance, have to meet rigorous colour accuracy standards - but I"ve seen plenty of non-G-Sync screens that barely cover 85% of the standard sRGB colour gamut, which means washed out colours and generally not very rich and vibrant images.

IPS monitors, on the other hand, are all about colour accuracy. Largely made by LG, there have actually been lots of different types of IPS panel that have emerged over the years as varying manufacturers tried their hand at matching the quality of LG"s panels, leading to dozens of different variations and combinations of acronyms. These days, though, most manufacturers (especially gaming ones) just tend to say they"re IPS as opposed a specific variant.

Unless, that is, it"s an AHVA, or Advanced Hyper-Viewing Angle, panel. Despite sounding like a VA panel (our third main panel type, which you"ll find more on below), AHVA is actually another type of IPS panel produced by AU Optronics and offers pretty much identical performance to a classic LG IPS panel.

The good: As I just mentioned, IPS panels generally have pretty great colour accuracy (I normally expect an sRGB coverage score of around 96% here) and wide viewing angles, making them better suited to colour intensive work and tasks like photo and video editing. This is true across all types of IPS panel, and their superior viewing angles (often quoted as 178 / 178 degrees) means you don"t get that nasty colour or contrast shift when you"re looking at the screen from a funny angle.

The bad: Unfortunately, their response times are often slower than TN panels, although these have become a lot better in recent years. Personally, I"ve never had any problems with latency when playing games on this type of screen, and for me, image quality is a lot more important than a couple of millisecond"s difference in overall response time.

They can also be more expensive to produce than TN panels, which, combined with their slower response times, is another reason why you don"t tend to see them a lot in displays designed primarily for gaming.

Finally, there"s the VA, or Vertical Alignment panel. Much like IPS, there are dozens of different types of VA panel, but the main ones we need to concern ourselves with are MVA (multi-domain vertical alignment) and AMVA (advanced MVA).

MVA panels were first designed to sit in the middle of TN and IPS displays, offering better viewing angles than TN screens and higher contrast ratios and deeper blacks than IPS. However, their colour accuracy isn"t quite as good as IPS, and they don"t have very fast response times, either.

AMVA, on the other hand (not to be confused with the IPS-like AHVA panel tech described above) builds on that even further, improving the panel"s colour accuracy while still maintaining those ultra high contrast ratios and deep blacks. Its viewing angles still aren"t quite as wide as IPS displays, though, and its response times are still a bit slower as well. However, through the use of features like a monitor"s Overdrive function, VA response times are now much faster than they used to be, making them a much more common occurrence in gaming screens, especially when it comes to curved or ultrawide displays.

The good: As a result, VA monitors can sort of be viewed as the ultimate compromise screen. The key advantages are their best in class black levels and their superior contrast ratios, and compared to TN panels, they also have better viewing angles and higher colour accuracy.

The bad: However, while VA might rectify some of the weaknesses you"ll find in TN screens, they"re still not as colour accurate as IPS panels, and their narrower viewing angles also can"t compete with their IPS rivals, either. Their main weakness, however, is their slow response time, which is generally said to be the slowest of the three main panel types. As I said, steps have been taken to try and mitigate this when it comes to putting a VA panel inside a gaming monitor, but if your gaming library consists solely of competitive shooters and the like, then you"re probably better off looking elsewhere.

Even after the introduction of newer display technologies, LCDs still remain relevant even today.LCD displays are used for multiple purposes (TV, Monitor, Mobile Phones, Laptops, Automobiles, etc.) and one single configuration cannot satisfy all the purposes. So, LCD displays come with two different panels – VA (Vertical Alignment) and IPS (In-Plane Switching) to satisfy the different viewing needs of consumers.

A VA panel offers a superior contrast ratio but a narrow viewing angle. Contrarily, an IPS panel offers a wide viewing angle but a low contrast ratio.

As mentioned earlier, displays with VA Panels provide a great contrast ratio. You can find VA panels that typically come with contrast ratios of 3000:1 or 6000:1. A comparable IPS panel will only have a contrast ratio of 1000:1.

VA panels have narrow viewing angles. You will only be able to have an immersive experience when you sit straight opposite the display. The wider angles will not provide you the same experience.

In this, the liquid crystals are arranged parallel to the glass substrate instead of the perpendicular alignment. Furthermore, the structure of crystals and the placement of electrodes differ from the one used in VA panels. The electrodes occupy more space that results in lower contrast and brightness of the screen.

With the IPS panels, you can view the TV / monitor from a wide-angle and still get an impressive picture quality. Unlike VA panels, you will notice very little difference in color reproduction when you sit at a wide-angle from the display.

But when it comes to black uniformity, the IPS panels are sub-par. These panels do a poor job in displaying a bright image in the center of a completely black screen.

One more major drawback with the IPS panels is that they exhibit a distinct phenomenon called ‘IPS Glow’. You will notice some light patches on the corners of the screen. This happens when excessive light is passed through the screen.

Initially, IPS panels are mainly used in TVs due to their wide viewing angles, as we can watch TV in our living room from anywhere. But due to their better quality, color accuracy and response time, LCD panels gradually occupied the high-end computer monitor and laptop screens

IPS:These panels have the highest color range. You will be able to enjoy a realistic gaming experience. Besides, they have better viewing angles. So, you won’t notice any drop in picture quality even when you are not sitting in front of your TV / monitor.

VA:Even though the color range is not as great as the IPS panel, it does a pretty good job in showing the color variations. But the viewing angle is narrow. So, you have to sit straight opposite the TV / monitor.

VA panel compensates for its decent color range with an impressive contrast ratio. You will be able to see great detailing in the difference between light and dark colors.

IPS:IPS panels have one of the highest refresh rates. While you easily find an IPS panel with a refresh rate of 144Hz, some of the latest ones come with a refresh rate of 360Hz. If you are a serious online-gamer, digital artist, or video editor, then you have to go with the highest refresh rate within your budget.

VA:VA panels have lower refresh rates than IPS panels. Most VA panels come with a refresh rate of 120Hz. If you want to have a higher refresh rate, then you have to be willing to spend extra. VA panels have a maximum refresh rate of 240Hz.

IPS:IPS panels generally come with a response time of 4 milliseconds. This would suffice for watching TV or playing most games. But, if you are playing racing games or first-person shooting games, you need to have a response time of less than 2 milliseconds.

VA:VA panels generally have a slower response time than IPS panels with 5 milliseconds. So, there is a higher chance for you to experience motion blur. But, some of the VA panels that come with an expensive price tag have faster response times.

IPS:When it comes to the viewing angle, IPS panels far outweigh the VA panels. They have wider viewing angles. You will experience no drop in picture quality even if you sit and watch the TV from an extreme angle.

VA:The VA panels have a very narrow viewing angle. You have to sit as close to the straight axis of the TV to enjoy the picture quality. If you sit wider, there will be a significant loss in the picture quality.

IPS:IPS panels do a decent job in the contrast ratio segment but they are nowhere close to that of VA panels. An IPS panel offers a contrast ratio of 1000:1. When you watch a black color environment in an IPS panel, the black color will be slightly greyed out.

VA:VA panels offer a superior contrast ratio of 6000:1 that is very impressive. It has the capacity to show dark environments as darker. So, you will enjoy the picture detailing shown by the VA panels.

IPS:IPS panels are not really great at displaying the uniform black color throughout the screen. Due to the low contrast ratio, the black color will appear slightly greyed out.

VA:VA panels have a good black uniformity. But it also depends on the TV model you go with. Not all TV models with a VA panel have good black uniformity. But it is safe to say that in general, VA panels have better black uniformity than an IPS panel.

To put it short, the main difference between the panels lies in the alignment of the liquid crystals. The alignment results in the differences in the performance and picture quality of the panels.

The VA panels are ideal for office/study use, high-end PC games, and online games. If you are looking for a panel for mixed usage, the VA panel should still suffice your needs.
