lcd panel tn vs va factory
In this guide, we’ll go over the differences between the most common monitor panels. We’ve compared IPS panels, TN panels, and VA panels to help give you more insight on your upcoming purchase.
However, the average consumer is clueless on the LCD panel technology used in their LCD monitor. A monitor’s panel type is a crucial feature that dictates how it performs as well as the kind of tasks it is best suited to accomplish. Therefore, it is important to understand panel technology so that you can be sure to choose the appropriate monitor for your gaming needs.
And, it is important for gamers to become familiar with these various panel technologies so that they can understand the variety of marketing buzzwords that companies use to describe the different LCD panel monitors on the market.
For instance, if you have $150 or less to spend, you’ll likely be forced to choose a TN panel. However, if you have more to spend, that doesn’t necessarily mean you will want to avoid a TN panel monitor, it just means that you will have more options.
This is an important question because the type of usage your monitor will see will be a big determining factor in which type of panel you can get. If you are going to use your monitor solely for competitive gaming—I’m talking CS:GO, LoL, COD, Dota 2, etc.—then a TN panel with a high refresh rate and low response time will be your best bet.
On the other hand, if you are more of a casual gamer, or you are planning on doing a lot of graphic design work on your monitor, you might want to look into a VA panel or an IPS panel. These panels don’t quite perform on the same level as a TN panel (in terms of response rate) and they cost a lot more for the same refresh rate. However, their picture quality is much better than TN panels and therefore, they are better-suited for graphics design work.
And, for that, a TN panel is your best bet as they offer lower response rates and higher refresh rates (at least, for the price you pay) than IPS or VA panels.
On the other hand, if you’re not playing super competitive games and you really enjoy the visual aspect of gaming, you’d be better off going with a VA or IPS panel as they offer better technology for displaying richer and more detailed visuals.
Some display types are appropriate for gaming, while others are best suited for graphics design. Other monitors are good for gamers who want the best visuals, while a different set of monitor panels work better for competitive gamers who need the most performance possible.
In this guide, we have broken down the different panel types and have explained their key features, as well as have compared them to their counterparts to help you better understand which type of panel would best meet your needs.
If you are looking at a monitor and it doesn’t clearly state what kind of panel it is, it’s probably safe to assume it’s a TN panel. What I mean by this is that, in most cases, for IPS panels and VA panels, the monitor manufacturer will include the panel type in the name of the monitor in an effort to make them stand out.
As I mentioned above, TN Panels owe their popularity to low manufacturing costs.However, they are also known for being able to deliver much higher response rates than IPS or VA panels. However, they are also known for being able to deliver much higher response rates than IPS or VA panels.
Because of their affordability, Twisted Nematic Displays with higher refresh rates (a feature you will pay more for) are more readily available than competing panels with high refresh rates.
The viewing angles on a TN panel are touted to be 160 degrees vertical and 170 degrees horizontal: these angles are considerably lower than the viewing angles presented by other panel technologies
Because of these problems, the consistency and color accuracy on a TN panel will suffer in comparison to IPS and VA panels, which, ultimately, makes this panel type less ideal for color-critical work such as photography and design, or even for gamers who want the best visuals possible.
The most notable selling point of In-Plane Switching panels is their consistency, improved viewing angles, and superior color accuracy when compared to other LCD technologies. Every color shade retains its unique identity and distinctiveness regardless of its position on the monitor.
These factors make IPS panels suitable monitors for graphic design work, as well as for gamers looking for the best visuals possible (but who don’t mind a drop in response rate.)
Perhaps the greatest strength of a VA panel is its ability to block light from the backlight when it isn’t wanted. This ability results in higher contrast ratios and deeper blacks which are several times better than that of the other LCD technologies discussed in this guide.
As power users already understand, one problem with LCD monitors is light from the backlight. When an LCD monitor wants to display black, the color filter will be positioned in such a manner that very little light from the backlight will seep through. While they try to do a reasonable job, their filters aren’t always perfect, thus, incapable of rendering the blacks deep as they should be.
Thankfully, VA panels are magnificent at that task. And thanks to the fact that they are susceptible to clouding or bleeding towards the edges of the screen, the screens are often considered as ideal candidates for movie enthusiasts and suitable for general purpose work.
The VA panels also feature improved viewing angles and good color reproduction. Their excellent color reproduction abilities make the monitors ideal devices for color-critical work, or for gamers who want to play their games with the best picture quality possible.
A considerable drawback of the VA panel is its low level of responsiveness with its pixels transitioning from one state to the next. This can cause more noticeable blurring when gaming.
Thankfully, the more modern versions of VA panels use a superior pixel overdrive feature that is not susceptible to the problems of the earlier versions.
It is quite difficult to state definitively what LCD monitor is better in the battle of TN vs IPS. This is because both TN LCD displays and IPS LCD displays have a share of advantages and disadvantages.
The quick responsiveness of TN panels makes them suitable for competitive gamers who rely on every split-second to achieve victory. (Though there is a lot of debate surrounding this considering that some believe that the average human brain can just compute about 25 frames per second.) The response time of most TN Panels, save for the high-end and very exceptional ones, is between 2ms and 5ms. This quick response rate is why gamers love TN Panels, as they are perfect for fast-paced games.
IPS Panels, on the other hand, feature a rather sluggish response time compared with TN panels. But the good news is that IPS technology is improving with each new generation of monitors.
IPS Panels owe their popularity to superior viewing angles. They are also not susceptible to color washout when viewing at an angle, which is a problem that is very common with traditional TN panels.
TN panels suffer from limited viewing angles, especially when looking from a vertical position. Colors tend to shift if viewed from an off-perpendicular position. When viewing TN panels from vertical positions, colors will change so much that they’ll invert past a certain angle.
The reason is that higher resolution monitors typically cost more and, so, if you’re going to pay all of that money for an ultra high definition monitor, you might as well get the panel that is best suited for displaying high-end visuals.
Of course, if you want a balance between higher resolutions and lower response rates, you might be better off sacrificing some in the visual department and going with a TN panel to get a monitor with a better response rate.
Both VA and IPS panels are commonly used in LED-backlit TVs today. Though they are both Liquid Crystal Display types, there are vast differences between their performances. The differences touch on contrast, viewing angle, response time, and black uniformity.
IPS Panels are a clear winner when it comes to viewing angle. IPS Panels, as already explained, have a wide viewing angle without any noticeable drop in image quality on the monitor.
VA panels recoup their losses when it comes to contrast. Contrast, as you might be aware, is one of the most important factors when it comes to picture quality. VA surpasses IPS panels when it comes to contrast.
When in a dark environment, black images or shades will appear gray on an IPS panel, considerably undermining the experience. VA contrast ratios are usually in the range of 3000:1 to 6000:1 while IPS contrast ratios are around 1000:1.
Neither VA panels or IPS panels are ideal if one of the main features you are looking for in a monitor is response rate. However, of the two, VA panels offer a slightly faster response time than IPS panels.
VA panels, on the other hand, were built specifically to address the deficiencies in both TN Panels and IPS panels. Their response time is slightly faster than the response time of IPS panels yet considerably lower than the response time of TN panels.
There have been improvements on TN panels to make them more suitable for color-critical work such as photo editing, but even with the said improvements, TN panels are still far from ideal when it comes to these types of tasks.
From a visual standpoint, VA panels are better than TN panels as they are capable of 8-bit color depth as well as wider viewing angles. They also feature better black uniformity and high contrast ratios as compared to TN panels.
In my opinion, though, the choice between a TN panel and VA panel is somewhat similar to the choice between a TN panel and an IPS panel: choose an IPS panel if you are mostly into competitive gaming and pick a VA panel if you want better visuals.
If you are a competitive gamer, nothing will serve you better than a TN panel. TN panels might have weaker images, low contrast, and limited viewing angles, but they offer very fast response times.
However, if you are into the best visuals possible and you want images that are more crisp and detailed while you game, then the ideal panel for you is an IPS panel. IPS panels are excellent in reproducing color. They also come with a wide viewing angle, which is a feature well-suited for graphic design artists.
VA panels are the compromise panel. They offer accurate colors and wide viewing angles, almost comparable to IPS panels. Their response time is a little slower than that of TN panels, but also a little faster than IPS panels. So, if you want to get a monitor that brings balance to what a TN panel and IPS panel bring, VA panels are the way to go.
At the end of the day, TN panels are probably the most popular option for serious gamers. They are more affordable and perform better in competitive scenarios.
So, why would anyone ever buy a TN panel? For starters, they’re cheap. They don’t cost a lot to produce, so they’re often used in the most budget-friendly options. If you don’t value color reproduction or need excellent viewing angles, a TN panel might be fine for your office or study.
TN panels also have the lowest input lag—typically around one millisecond. They can also handle high refresh rates of up to 240 Hz. This makes them an attractive option for competitive multiplayer games—especially eSports, where every split-second counts.
IPS technology was developed to improve upon the limitations of TN panels—most notably, the poor color reproduction and limited viewing angles. As a result, IPS panels are much better than TNs in both of these areas.
In particular, IPS panels have vastly superior viewing angles than TNs. This means you can view IPS panels from extreme angles and still get accurate color reproduction. Unlike TNs, you’ll notice very little shift in color when you view one from a less-than-ideal perspective.
IPS panels are also known for their relatively good black reproduction, which helps eliminate the “washed out” look you get with TN panels. However, IPS panels fall short of the excellent contrast ratios you’ll find on VAs.
While high refresh rates were typically reserved for TNs, more manufacturers are producing IPS panels with refresh rates of 240 Hz. For example, the 27-inch 1080p ASUS VG279QM uses an IPS panel and supports 280 Hz.
Previously, TNs exhibited less input lag than any other panel, but IPS technology has finally caught up. In June 2019, LG announced its new Nano IPS UltraGear monitors with a response time of one millisecond.
Despite the gap being closed, you’ll still pay more for an IPS panel with such a low response time than you would for a TN with similar specs. If you’re on a budget, expect a response time of around four milliseconds for a good IPS monitor.
One last thing to be aware of with IPS panels is a phenomenon called “IPS glow.” It’s when you see the display’s backlight shining through it at more extreme viewing angles. It’s not a huge problem unless you view the panel from the side, but it’s something to keep in mind.
VA panels are something of a compromise between TN and IPS. They offer the best contrast ratios, which is why TV manufacturers use them extensively. While an IPS monitor typically has a contrast ratio of 1000:1, it’s not unusual to see 3000:1 or 6000:1 in a comparable VA panel.
In terms of viewing angles, VAs can’t quite match the performance of IPS panels. Screen brightness, in particular, can vary based on the angle from which you’re viewing, but you won’t get the “IPS glow.”
VAs have slower response times than TNs and the newer Nano IPS panels with their one-millisecond response rates. You can find VA monitors with high refresh rates (240 Hz), but the latency can result in more ghosting and motion blur. For this reason, competitive gamers should avoid VA.
Compared to TNs, VA panels do offer much better color reproduction and typically hit the full sRGB spectrum, even on lower-end models. If you’re willing to spend a bit more, Samsung’s Quantum Dot SVA panels can hit 125 percent sRGB coverage.
For these reasons, VA panels are seen as the jack of all trades. They’re ideal for general use, but they either match or fall short in most other areas except contrast ratio. VAs are good for gamers who enjoy single-player or casual experiences.
When compared to CRT monitors, all LCD panels suffer from some form of latency issue. This was a real problem when TN panels first appeared, and it’s plagued IPS and VA monitors for years. But technology has moved on, and while many of these issues have been improved, they haven’t been eliminated entirely.
Uneven backlighting is another issue you’ll find on all panel types. Often this comes down to overall build quality—cheaper models slack on quality control to save on production costs. So, if you’re looking for a cheap monitor, be prepared for some uneven backlighting. However, you’ll mostly only notice it on solid or very dark backgrounds.
LCD panels are also susceptible to dead or stuck pixels. Different manufacturers and jurisdictions have different policies and consumer laws covering dead pixels. If you’re a perfectionist, check the manufacturer’s dead-pixel policy before you buy. Some will replace a monitor with a single dead pixel for free, while others require a minimum number.
Office or study use: Your budget should be your primary concern here. VA is the do-it-all panel, with superior viewing angles to TN, but either would do the trick. You can save some money because you don’t need high refresh rates or ultra-low latency. They’re still nice, though. You’ll see a noticeable difference in smoothness just when moving the Windows cursor on a monitor with a 144 versus 60 Hz refresh rate.
Photo and video editors/Digital artists: IPS panels are still generally favored for their ability to display a wide gamut of colors. It’s not unusual to find VA panels that also cover a wide gamut (125 percent sRGB, and over 90 percent DCI-P3), but they tend to exhibit more motion blur during fast-paced action than IPS panels. If you’re serious about color accuracy, you’ll need to properly calibrate your monitor.
Programmers who mount monitors vertically: You might think TN panels are great for programmers, but that’s not necessarily the case. TN panels have particularly bad viewing angles on the vertical axis. If you mount your monitor in portrait mode (as many programmers and mobile developers do), you’ll get the worst possible viewing angles from a TN panel. For the best possible viewing angles in this scenario, invest in an IPS display.
Competitive online gamers: There’s no question TN panels are still favored in the eSports world. Even the cheapest models have fast response times and support for high refresh rates. For 1080p gaming, a 24-inch will do just fine, or you could opt for a 1440p, 27-inch model without breaking the bank. You might want to go for an IPS panel as more low-latency models hit the market, but expect to pay more.
Non-competitive, high-end PC gamers: For a rich, immersive image that pops, a VA panel will provide a higher contrast ratio than IPS or TN. For deep blacks and a sharp, contrasting image, VA is the winner. If you’re okay with sacrificing some contrast, you can go the IPS route. However, we’d recommend avoiding TN altogether unless you play competitively.
Best all-rounder: VA is the winner here, but IPS is better in all areas except contrast ratio. If you can sacrifice contrast, an IPS panel will provide fairly low latency, decent blacks, and satisfactory color coverage.
If you can, check out the monitor you’re interested in in-person before you buy it. You can perform some simple ghosting and motion blur tests by grabbing a window with the mouse and moving it rapidly around the screen. You can also test the brightness, watch some videos, and play with the onscreen display to get a feel for it.

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.
Everyday, we look at LCD display, TV, cell phone, monitor. It becomes a necessity in modern society. LCD panel is the most important part of an LCD display. It determines LCD screen"s performance, e.g. brightness, contrast, color and viewing angle. Therefore, picking the right type of LCD panel is critical to your application.
Vertical Alignment (VA): Also referred to as “super vertical alignment” (SVA) and “advanced multi-domain vertical alignment” (AMVA). They all share similar characteristics.
These names reflect the alignment of crystal molecules inside the LCD, and how they change when they are charged electrically. All liquid crystal displays change the alignment of liquid crystal molecules to work, but the manner in which they do so can drastically affect the image quality and response time. Each panel type has its advantages and disadvantages. The easiest way to choose between them is to decide which attributes are most important to your project. It mainly depends on what you use your LCD display for, and your budget.
TN is the most mature technology in LCD panel manufacturing. When there is no voltage difference between the two transparent electrodes, liquid crystal molecules are twisted 90 degrees, in combination of upper and bottom polarizers, allows light to pass through LCD. As voltage applied, crystal molecules are untwisted and aligned to the same direction, blocking light.
In IPS panel, crystal molecules are parallel to the glass substrates at initial stage, LCD is off. When the in-plane electrodes is charged, crystal molecules are rotated, modifying light"s direction. Which lights up the LCD display.
As its name suggests, VA panel"s liquid crystals are aligned vertically without charged. When a voltage is applied, the molecules tilt and modifying light direction.
So in summary, TN panels twist, IPS panels use a parallel alignment and rotate, while VA panels use a perpendicular alignment and tilt. These difference create LCD display with distinctive performance.
IPS LCD is the clear winner in this aspect. It has 178/178 viewing angle ratings. Which means you can look at IPS LCD display from any angle without the image shifting in color and contrast. VA LCD has pretty wide viewing angle, too. But it has contrast shifts at off-center angles. As for TN LCD, viewing angle is its weakest point.
Most TN LCDs have 6-bits colors. Manufacturers use frame rate control (FRC) to enhance its color performance. For IPS and VA panels, you can still find 6-bits entry level LCD. But most of them are 8-bits. And IPS technology can provide natively 10-bits colors.
Color gamut is another part that VA and IPS panels shine at. The best TN LCD can reach sRGB gamut. VA panels typically start with full sRGB coverage, and get to around 90% DCI-P3 coverage. With IPS LCD panel, you could find the best ones full DCI-P3 and Adobe RGB coverage. That is why you see most professional grade LCD displays use IPS panel.
There is no inherent differences among the three panel technologies, because LCD backlight is the main factor here. However, there is a big gap in terms of contrast ratio. TN LCD panel tends to have the lowest value among the three. IPS LCD screen sits in the middle can reach 1500:1. For VA panel, the best one can exceed 4500:1 easily. VA LCD display provides far darker screen than TN & IPS. That is why they are used in vehicle dashboard.
TN panel does have an advantage when it comes to refresh rate. The panel offers the best refresh rate and response time. This is the reason why most gaming LCD monitors are made of TN panel.
TN LCD provides the best refresh rate and economic solution. If your application requires wide viewing angles and good color presentation, VA panel is probably the choice. While IPS has the best overall visual performance, in general it is more expensive than the other two.
By far the most common types of display panels used on PC monitors are TN, IPS and VA. We"re sure you"ve heard these terms before if you"ve researched monitors to purchase, and to be clear, the type of panel is a key piece of information that reveals a lot about how the monitor will behave and perform.
TN is the oldest of the LCD technologies and it stands for twisted nematic. This refers to the twisted nematic effect, which is an effect that allows liquid crystal molecules to be controlled with voltage. While the actual workings of a TN-effect LCD are a little more complicated, essentially the TN-effect is used to change the alignment of liquid crystals when a voltage is applied. When there is no voltage, so the crystal is "off," the liquid crystal molecules are twisted 90 degrees and in combination with polarization layers, allow light to pass through. Then when a voltage is applied, these crystals are essentially untwisted, blocking light.
VA, stands for vertical alignment. As the name suggests, this technology uses vertically aligned liquid crystals which tilt when a voltage is applied to let light pass through. This is the key difference between IPS and VA: with VA, the crystals are perpendicular to the substrates, while with IPS they are parallel. There are several VA variants, including Samsung"s SVA and AU Optronics AMVA.
IPS stands for in-plane switching and, like all LCDs, it too uses voltage to control the alignment of liquid crystals. However unlike with TN, IPS LCDs use a different crystal orientation, one where the crystals are parallel to the glass substrates, hence the term "in plane". Rather than "twisting" the crystals to modify the amount of light let through, IPS crystals are essentially rotated, which has a range of benefits.
There are many IPS variants on the market, with each of the three big LCD manufacturers using a different term to describe their IPS-type technology. LG simply calls their tech "IPS" which is easy for everyone. Samsung uses the term PLS or plane-to-line switching, while AU Optronics uses the term AHVA or advanced hyper viewing angle. AHVA shouldn"t be confused with regular VA displays, it"s an annoying and confusing name in my opinion, but AHVA is an IPS-like technology. Each of LG"s IPS, Samsung"s PLS and AUO"s AHVA are slightly different but the fundamentals are rooted in IPS.
So in summary, TN panels twist, IPS panels use a parallel alignment and rotate, while VA panels use a vertical alignment and tilt. Now let"s get into some of the performance characteristics and explore how each of the technologies differ and in general, which technology is better in any given category.
By far the biggest difference between the three technologies is in viewing angles. TN panels have the weakest viewing angles, with significant shift to color and contrast in both the horizontal and especially vertical directions. Typically viewing angles are rated as 170/160 but realistically you"ll get pretty bad shifts when viewing anywhere except for dead center. Higher-end TNs tend to be somewhat better but overall this is a big weakness for TNs.
VA and IPS panels are both significantly better, with IPS being the best overall for viewing angles. 178/178 viewing angle ratings are a realistic reflection of what you can expect with an IPS, you won"t get much shift in colors or contrast from any angle. VAs are good in this regard but not as good as IPS, mostly due to contrast shifts at off-center angles. With VAs and especially TNs having some color and contrast shifts when viewing at angles, they"re not as well suited to color-critical professional work as IPS panels, which is why you see most pro-grade monitors sticking to IPS.
In terms of brightness there"s no inherent differences between the technologies because the backlight, which determines brightness, is separate to the liquid crystal panel. However there are significant differences to contrast ratios, and this an area most people look at when determining which panel type they want.
Both TN and IPS panels tend to have a contrast ratio around 1000:1, although in my testing I have noted some differences. TN panels tend to have the lowest contrast ratios when calibrated, with an entry-level panel sitting between 700:1 and 900:1 and good panels pushing up to that 1000:1 mark. IPS has a larger range, I"ve seen some as low as 700:1 like TNs, however the very best tend to push up higher than TN, with 1200:1 as the upper range for desktop monitors and some laptop-grade displays reaching as high as 1500:1.
Neither TN nor IPS get to the range of VA though. Entry-level VA panels start with a contrast ratio of 2000:1 from those that we"ve tested, with the best easily exceeding 4500:1, although 3000:1 is a typical figure for most monitors.
TVs make extensive use of VA panels and there contrast ratios can be even higher. It"s not unusual to see over 6000:1. So if you want deep blacks and high contrast ratios, you"ll need to go with something VA.
While IPS panels tend to be a middle ground for contrast they do suffer from a phenomenon called "IPS glow," which is an apparent white glow when viewing dark imagery at an angle. The best panels exhibit minimal glow but it"s still an issue across all displays of this type.
Color quality is another difference many people cite between TN displays and other display panels in particular. And this can be split into two categories: color depth or bit depth, and color gamut.
In both of these regards, TN panels tend to fall on the weaker end of the scale. Many TN displays, in particular entry-level models, are only natively 6-bit and use frame rate control, otherwise called FRC or dithering, to achieve standard 8-bit output. 6-bit panels are prone to color banding, while native 8-bit panels have smoother color gradients and therefore better color output.
Not all TN panels are 6-bit. The top-end TNs are native 8-bit, but it"s safe to say most TNs will only be native 6-bit, even today. If you are after a native 8-bit display, you"ll need to go with either IPS or VA, where many more panels come native 8-bit.
As for native true 10-bit, typically you"ll need to look for an IPS panel, which make up the majority of native 10-bit panels. Some VA panels can do it, but they are rare. Most displays you purchase that claim to be 10-bit, are actually 8-bit+FRC, with only high-end professional-grade monitors offering a native 10-bit experience.
This is another area where VA and IPS provide a superior experience. The best TN panels tend to be limited to sRGB, or in the case of the worst entry-level panels, don"t even cover the entirety of the sRGB gamut. Wide-gamut TN panels do exist, but they are rare.
VA panels typically start with full sRGB coverage as a minimum, and depending on the panel can push higher. VAs that use a quantum dot film, typically from Samsung, offer higher gamuts, around the 125% sRGB or 90% DCI-P3 mark. Most of the wide gamut VA monitors we"ve tested fall between 85 and 90% DCI-P3 coverage, which is a decent result, though the best can approach 95% or higher.
With IPS panels, there is the largest variance. Entry-level IPS displays tend to offer 95% sRGB coverage or less, while the majority stick to full sRGB coverage. Then with high-end displays, usually for professionals, it"s not unusual to see full DCI-P3 and Adobe RGB coverage. Of all the wide gamut IPS displays I"ve tested, the lowest DCI-P3 coverage I"ve seen has been 93%, with over 95% a typical figure. This makes IPS the best technology for wide gamut work.
Throughout most of this discussion we"ve been talking about TN as the worst of the three technologies. So far, it has the worst color reproduction, contrast ratios and viewing angles. But it does have one key advantage, and that comes in the form of speed. TN panels have historically been the best for both refresh rates and response times, however that trend is slowly changing for the better.
Not long ago, we argued that only with a TN panel it was possible to hit 240 Hz, doing so at 1080p and later up to 1440p. Most recently, however we"ve seen IPS monitors hit the highest mark ever for a consumer-grade gaming monitor at 360Hz, and do so very convincingly. We"re sure other monitors will follow but as of writing, the Asus ROG Swift PG259QN can deliver both the fastest response times and an accurate color experience using an IPS panel.
More mainstream monitors using IPS panels tend to range from the regular 60Hz for productivity, up to 165 Hz and 240 Hz depending on the market they"re aimed at. VA panels top out at around 240 Hz at the moment.
Most IPS displays, especially high-grade options for professionals, as well as entry-level office monitors, are either 60 or 75 Hz. Meanwhile, a significantly larger number of VA panels across a wider range of sizes and resolutions are high-refresh, while the big selling point of TN is its super high refresh capabilities.
Another major consideration is response times, which govern the level of ghosting, smearing and overall clarity of a panel. Early IPS and VA panels were very slow, however this has improved a lot with modern panels, so the differences between the three technologies aren"t as pronounced as they once were. TN still holds an advantage here.
Most TN panels have a rated transition time of 1ms, or even lower with some recent releases. Actual grey to grey averages we"ve measured for TN panels tend to be in the 2-3 ms range when overdrive is factored in, which makes TN the fastest technology.
IPS panels are next in terms of speed, though as tends to be the case with IPS, there is a wide variance between the best and worst of this type. High-end IPS monitors, typically those with high refresh rates, can have a transition time as fast as 3ms. Compared to the best TN panels, this still makes IPS slower. However entry-level IPS panels or those without overdrive sit closer to the 10ms range, while mid-tier options tend to occupy the 5 to 7 ms bracket.
VA panels are consistently the slowest of the three types, but again, high-end gaming monitors have been pushing this further on every generation. The absolute fastest VA panel we"ve measured so far has a 4ms response time which is very impressive, though more typical numbers are between 8 and 10 ms for gaming monitors. VA panels also tend to be less consistent with their transitions; some individual transitions can be fast, while others very slow, whereas IPS panels tend to hover more around their overall grey to grey average.
While a lot of people are unlikely to spot the difference between an 8ms VA panel and a 5ms IPS, TN panels overall tend to be noticeably clearer in motion, but that gap is closing with every generation. The slowness of VA panels also limits their real world refresh rate: a 144 Hz panel that only manages a 9ms response time, is actually delivering an image most equivalent to a 110 Hz panel. Whereas most 144 Hz IPS panels can transition faster than the 6.94ms refresh window, leading to a true 144 Hz experience. So that"s something to consider.
As a quick summary, TN panels are the fastest and have the highest refresh rates, however they have the worst viewing angles by far, as well as weak color performance and typically the lowest contrast ratios. TNs are typically used for ultra-fast gaming displays, as well as budget class displays, for both desktop monitors and laptops.
IPS is a middle-ground technology. They typically have the best color performance and viewing angles, mid-tier response times and refresh rates, along with mid-tier black levels and contrast ratios. Due to its top-end color output, IPS panels are the go-to choice for professionals, but you"ll also find them in entry-level displays, office monitors, most laptops and a handful of gaming monitors.
VA panels are the slowest of the three, but have the best contrast ratio and black levels by far. Color performance isn"t quite at the level of IPS, but they still offer a significantly better experience than TN in this regard.
With response times for the best modern VAs approaching the level of a typical IPS, along with broad support for high refresh rates, VA monitors are commonly used for gaming monitors. Entry-level VAs also tend to be superior to entry-level TN and IPS panels, though you won"t find VA used in laptops.
There"s no right answer to which monitor technology is best, because all have their strengths and weaknesses which is why all three coexist on the market today. However if you want our recommendation, we tend to gravitate towards VA panels for most buyers, especially gamers and those after something entry-level. Creative professionals should be looking exclusively at IPS monitors, while those after something dirt cheap or ultra high refresh for competitive gaming should opt for TN, although superior latest-gen IPS and VA offerings are finally matching or even beating the best of TN in some regards.
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.
After thorough analysis, details of advantageous molecular arrangements were filed in Germany by Guenter Baur et al. and patented in various countries including the US on 9 January 1990.Fraunhofer Society in Freiburg, where the inventors worked, assigned these patents to Merck KGaA, Darmstadt, Germany.
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.
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.
In practice, other schemes of implementation exist with a different structure of the LC molecules – for example without any twist in the OFF state. As both electrodes are on the same substrate, they take more space than TN matrix electrodes. This also reduces contrast and brightness.
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.

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.
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.
Looking for your next gaming or workstation monitor? Well, when it comes to computer monitors, you have to choose from the three main LCD panel types – TN (twisted nematic), VA (vertically aligned), and IPS (in-plane switching). So, you basically come across these three types of panels when looking for a monitor. They all are flat screen display technologies with similar structures and functions, but the detailed structure of the color filters array varies greatly in each liquid crystal mode. The difference lies in how the liquid crystal molecules are aligned with respect to the substrate plane, and how they reach when voltage is applied. Each display panel has its pros and cons. Let’s take a look at each of them.
TN is the original mode created for LCDs and it is the oldest among the LCD panel display technologies. TN stands for twisted nematic and it’s the most commonly used panels in computer monitors. Like the name suggests, it uses a nematic kind of liquid crystals which are twisted by an angle of about 90-degree and are sandwiched between a pair of polarizers. The direction of polarization of the beam is rotated by 90 degree. It takes advantage of something called an “active 3D shutter” technology which allows them to display twice as much information every second compared to other panels. However, the biggest downside of the conventional TN panels is their poor viewing angle performance. Also, image quality deteriorates when multiple viewers are looking at the display from different angles.
VA stands for vertically aligned and is yet another successful approach to improve the viewing angle capability. VA panels are characterized by their superb contrast ratio and image depth as compared to other LCD panel types. In VA panels, the nematic liquid crystal molecules are aligned perpendicular to the glass substrate plane in the absence of an electric filed. This requires a different kind of alignment layer. The VA mode got rid of the rubbing process, which ultimately translates to a yield advantage. Because of their improved viewing angle performance and best contrast ratio in the segment, the VA panels emerged as the leader in display technology in 2007.
IPS stands for in-plane switching and it is a screen technology for liquid crystal displays developed to get rid of the limitations of the conventional TN panels – mostly the poor color reproduction and viewing angle performance. In IPS panels, the liquid crystal molecules are aligned in parallel to produce rich colors. Two counter electrodes are formed on the TFT substrate and switching is achieved by the rotation of the LC molecules. IPS panels are arguably the best in class in terms of viewing angle behavior, color reproduction, faster response times, exceptional color accuracy, and screen consistency. This is why IPS panels are mostly used for rendering, but the downs
