lcd panel ips vs tn quotation
In general, IPS, PLS, and VA panels will maintain outstanding image quality and low color degradation no matter where in the room you’re viewing from. A huge boon.
Remember the hype surrounding the final season of Game of Thrones? Now, do you remember the battle with the White Walkers? More specifically, howdark the episode was? If you couldn’t see very well, chances are you weren’t using a VA panel.
VA panels are known to deliver the deepest blacks and richest all-around tones, thanks to their high contrast ratios. This is also why they’re commonly found in television sets. That said, IPS panels come in close behind with contrast ratios of roughly 1000:1.
Due to the comparatively simple nature of TN liquid crystal technology, most TN displays boast low response times between 5ms and 1ms. This allows games to transition from scene-to-scene with very little lag and virtually zero ghosting.
TN panels also feature the highest refresh rates, which is how many times per second a display can re-render a scene (critical for reaching maximum FPS).
High response times and refresh rates are a huge boon for gaming, where split second decisions can make or break a game. As such, TN panels are the optimal choice for PC gamers looking to maximize their competitive advantage.
Given their inexpensive manufacturing costs, TN panels are the most affordable type on our list. In price-ascending order, they’re followed by VA panels, PLS panels, and IPS panels.
Do note, however, that different display models offer different features. High-end TN panels can easily cost more than an entry-level IPS. It depends on the specifications, manufacturer, and various other factors.
Choosing the best panel type ultimately comes down to personal needs and preference. That said, we hope these guidelines help. Your perfect display is out there.
Whether you’re seeking a VA vs IPS vs TN monitor, we’ve assembled this list of the web’s most frequently asked questions to offer an easy solution to all your display inquiries.
When searching for a liquid crystal display (LCD), consideration of the device’s display technology is essential. Screen technology companies such as Apple and Samsung search for the best possible display panels and panel technology in order to offer their customers the best image quality. In competitive gaming, gaming monitors must be able to provide great image quality but also fast refresh rates so that gamers can play at a fast pace.
Before diving into how exactly liquid crystals affect display features, it is necessary to understand their general role in an LCD monitor. LCD technology is not capable of illuminating itself, so it requires a backlight. The liquid crystals are responsible for transmitting the light from backlight to the computer monitor surface in a manner determined by the signals received. They do so by essentially moving the light differently through the layer’s molecular matrix when the liquid crystals are oriented or aligned in a certain manner, a process which is controlled by the LCD cell’s electrodes and their electric currents.
The methods of alignment, however, can vary between panel types, offering different features and benefits. Two common and popular liquid crystal alignment techniques are twisted nematic (TN) and in-plane switching(IPS).
TN panels offer the cheapest method of crystal alignment. They also are the most common of the alignment methods and have been used for quite a long time in the display industry, including in cathode ray tubes (CRTs) that preceded the LCD.
In TN displays, the electrodes are positioned on either side of the liquid crystal layer. When a current is sent between the back and front electrode, something called an electric field is created that shifts and manipulates the orientation of the molecular matrix.
If no electric field is applied to the specific cell, the crystals experience a 90 degree twist in the alignment. As light from the backlight passes through this twist, the light waves are polarized, allowing them to pass through the polarizer that sits on the surface of the TN monitor.
If an electric field is applied, it can either untwist the TN liquid crystal layer partially or in full, depending on the strength of the field. The structure of TN crystals will typically straighten out when this happens, and some, if not all, light waves will not be polarized properly to pass through to the surface.
Each LCD cell composes a pixel of the display, and in each pixel are subpixels. These subpixels use standard red green blue (sRGB) colors to create a variety of colors to make the pixel display the necessary color to play its role in the overall display. If beneath the subpixel the liquid crystal fully polarizes the light, that subpixel’s specific color would be very bright in the pixel as a whole. But if the light is not polarized at all, then that color will not show up. If partially polarized, only a limited amount of that color is used in the mixture of RGB colors in the final pixel.
A more complex method of alignment is IPS. IPS monitors, unlike the TN, place both electrodes on the same level, behind the liquid crystal layer. When the electric field is applied, this forces the liquid crystal molecules to align themselves parallel to the IPS device layers instead of perpendicularly like the TN molecules.
Opposite of the TN, when the electric field is applied, IPS technology will polarize the light to pass, whereas when the electric field is not applied, the light will not be polarized to pass. Because of the orientation of the crystals, IPS displays require brighter, more powerful backlights in order to produce the correct amount of brightness for the display.
An important consideration is viewing angles. The TN offers only a limited viewing angle, especially limited from vertical angle shifts, and so color reproduction at these angles will likely not look the same as from a straight-on viewing; the TN’s colors may invert at extreme angles. The IPS counters that and allows for greater and better viewing angles that consequently offer better color reproduction at these angles than the TN. There is one issue with extreme viewing angles for IPS devices: IPS glow. This occurs when the backlight shines through the display at very wide angles, but typically is not an issue unless a device is looked at from the side.
In terms of color, as mentioned, TN devices do not have very strong color reproduction compared to other alignment technologies. Without strong color reproduction, color banding can become visible, contrast ratio can suffer, and accurate colors may not be produced. Color gamut, or the range of colors that the device can reproduce and display, is another feature that most TN displays do not excel in. This means that the full sRGB spectrum is not accessible. IPS devices, on the other hand, have good quality black color reproductions, allowing the device to achieve a deeper, richer display, but it is still not the best option if a customer is in search of high contrast (discussed further in a couple more paragraphs).
While TNs may not have the best color quality, they allow for high refresh rates (how often a new image is updated per second), often around 240 Hz. They also have the lowest input lag (receiving of signals from external controllers) at about one millisecond. TN panels often attract gamers because of the need for minimal lag and fast refresh rates in a competitive or time-sensitive setting. In consideration of moving displays like in video game displays, it is also important for fast response times (how fast a pixel can change from one amount of lighting to another). The lower the response time (the higher the response rate), the less motion blur will be shown as the display changes to show motion. TNs also offer these low response times, but it is important to remember that a powerful graphics processing unit, commonly called a GPU, is still needed to push these displays to meet the fastest refresh and response rates.
Standard IPS devices have been known to have slower response time and refresh rates. This can often lead to not just motion blur but ghosting as well, meaning that an image does not refresh fast enough, and so the previous image will remain temporarily burned in the expected new image. In recent years, though, IPS technology has achieved higher refresh rates than in the past through the super-IPS, abbreviated s-IPS.
Oftentimes, refresh rates and frame rate of output devices (such as graphics cards) will not be synchronized, causing screen tearing when two different display images will be shown at once. This problem can be addressed through syncing technologies like Vsynch, Nvidia’s G-Sync, or FreeSync (a royalty-free adaptive synchronization technology developed by AMD).
Another common consideration of customers is the price of each display. TN, though it does not offer as high quality of a display, offers the lowest cost and best moving displays, making it useful if the intended use of the LCD monitor is simple and not too demanding. However, if you intend for something that calls for better color production or viewing angles, the IPS and other methods are viable choices, but at much higher costs. Even though IPS motion displays have reached the speed and rates of TNs, the price for such technology is much more expensive than the TN option.
There are other options besides the TN and IPS. One option is known as vertical alignment (VA) and it allows for the best color accuracy and color gamut. Compared to a typical IPS contrast ratio of 1000:1, VA panels can often have ratios of 3000:1 or even 6000:1. Besides improved contrast ratio, the VA is in between the TN and IPS. To compare the TN vs IPS vs VA, the VA does not have as great a viewing angle as IPS but not as poor as the TN. Its response times are slower than TN but faster than IPS (though at fast refresh rates, the VA displays often suffer from ghosting and motion blur). Due to the contrast ratio benefits, VA technologies are most often desirable for TVs.
And lastly, there is an option quite similar to IPS that is called plane to line switching (PLS). It is only produced by Samsung, who claims the PLS offers better brightness and contrast ratios than the IPS, uses less energy, and is cheaper to manufacture (but because it is only created by Samsung, it is hard to judge pricing). It also has potential in creating flexible displays.
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.
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.
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.
Viewing angles, on the other hand, are a bit more of a hurdle. Most of the time you"ll see them quoted as 160 / 170 degrees, but unless you"re looking at the screen just right, colours can sometimes look a bit off, while contrast goes up the spout. As a result, getting a TN monitor with a height-adjustable stand as opposed to a fixed one can often be a good way to counteract this problem, as this gives you more flexibility to get the monitor in exactly the right position.
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.

The Dell S2716DG came as a surprise and during our tests we were surprised as well, although not always in a positive way. The colour quality disappoints, the gamma is not the best and the black value is a bit substandard. Nevertheless, when compared with its main – and the only one we could test – competitor, the Asus PG278Q, we have to come to the conclusion that Dell only performs slightly worse in terms of brightness and contrast as well as colour- and grey deviation while having better viewing angles, similar colour temperature and similar response times. All of this, while the price is 46 pounds / 60 euros less, on average even more than 76 pounds / 100 euros.
Consider you’re buying a new gaming monitor. Now, before you head out (or online), there are many things to consider. The resolution and refresh rates are just the tips of the ice-berg. When it comes to PC monitor display panels, you’ve got three options: IPS, TN and VA. If you are a gamer which panel is right for you? Do you need an IPS display, a TN panel, or a VA panel?
All three of these are different flavors of LCD monitors. They’re built using fundamentally similar technology–this isn’t the difference between LCD and OLED. All three have advantages and substantial weakness. This means that they are ideal for different use cases. You’ll want to know these as a gamer to identify what’s right for you.
TN is short for twisted nematic, referring to the LCD substrate that’s used in this type of display. TN panels are a very mature technology and are the cheapest kind of LCD display to produce. This means that you’ll get TN panels for a given screen size/resolution at a lower price than other options.
TN panels aren’t just cheap. They tend to have lower response times than other monitor panels. This makes them exceptionally well-suited for low-latency use cases like eSports gaming. As a result, many eSports-oriented high-refresh rate monitors utilize TN technology.
There are notable downsides, though. For starters, viewing angles are terrible. Even if you look at a TN panel from its exact center, you’ll experience picture quality degradation at the edges. Poor viewing angles mean that color is only accurately reproduced at the very center of the panel, from your perspective. Some TN panels have better viewing angles than others, but almost all are beaten by even budget VA and IPS sets in this respect.
Another thing? Color reproduction is poor on TN panels. Colors, in general, appear washed-out. But what’s most noticeable is the poor contrast levels. In poorly-illuminated scenes, black appears grey. All in all, we find TN panels hard to recommend anymore. If you want an eSports panel, but can’t afford a high-performance IPS, a TN panel might be right for you. Otherwise, look elsewhere.
IPS is short for in-plane switching. IPS displays were actually developed to address the shortcomings of TN panels. In IPS panels, the orientation of liquid crystal molecules is arranged and switched parallel to the substrate. This allows for accurate color reproduction across a much wider range of viewing angles.
IPS panels have clear advantages over TN panels. For starters, color reproduction is excellent. High-end IPS monitors that cover a significant amount of the sRGB gamut not only look great–they’re an excellent choice for professional photographers and graphic designers. Contrast is much-improved on IPS: while you don’t get the inky blacks of OLED, dark areas look reliably dark, while retaining detail. IPS panels tend to have a slower refresh rate than TN panels.
However, gaming-oriented IPS models are available with low response time and higher refresh rates. They just cost a lot more than comparable TN parts. IPS panels are our go-to recommendation. They offer great image quality, while also allowing for low-latency, high refresh rate gaming.
VA is short for vertical alignment. In these displays, LCD cells align vertically when no electricity is passing through. They align horizontally when it is, allowing light through. VA panels offer excellent image quality. Even budget VA monitors deliver contrast ratios in excess of 3000:1. This translates into rich colors, and detail preservation in dark scenes.
VA is ideal if media consumption is your primary use case: you get excellent image quality. The trade-off here is that VA panels tend to have the worst response times. Response times higher than 4ms are typical. On the worst offenders, input lag is actually somewhat notable. And while viewing angles are better than TN panels, VA panels often exhibit color shifting–with colors going off-hue at wide angles. Some VA panels also have a “ghosting” issue, especially when handling rapidly moving images.
This makes VA panels a questionable choice for eSports gaming. If you mainly play single-player titles, though, VA panels are a great choice. Price-wise, they tend to be cheaper than their IPS counterparts while offering great image quality.
If you’re an eSports gamer, you need a monitor with the lowest-possible response rate and a high refresh rate. Both IPS and TN panels enable this. At a premium budget, you should look at IPS panels, as they offer the best combination of picture quality and low latency. If you’re on a tighter budget, a TN panel can get the job done, although you’ll be compromising somewhat on the image.
Other than the display panel, you also need to look at some of the other specifications such as the color gamut, HDR support, contrast ratio, etc. You can read more about how to pick the right config here.

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.
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.

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, office work, programming, 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
Compared to the widespread TN LCD format, the main benefits of in-plane-switching (“IPS”) display technology are the extra wide viewing angles of +/-80 degrees all around, as well as the extensive high contrast ratio of 900:1.
Furthermore, IPS LCD displays are not affected by viewing-angle dependent color changes and/or washout effects like TN displays.Equally important, IPS displays stand out with their superior and brilliant color image representation.
By example, you can find our high end 5.0 inch IPS panel with 950 nits brightness, 800×480 resolution and capacitive touch-panel here: ATM0500D27K-CT.

Liquid Crystal Display (LCD) screens are a staple in the digital display marketplace and are used in display applications across every industry. With every display application presenting a unique set of requirements, the selection of specialized LCDs has grown to meet these demands.
LCD screens can be grouped into three categories: TN (twisted nematic), IPS (in-plane switching), and VA (Vertical Alignment). Each of these screen types has its own unique qualities, almost all of them having to do with how images appear across the various screen types.
This technology consists of nematic liquid crystal sandwiched between two plates of glass. When power is applied to the electrodes, the liquid crystals twist 90°. TN (Twisted Nematic) LCDs are the most common LCD screen type. They offer full-color images, and moderate viewing angles.
TN LCDs maintain a dedicated user base despite other screen types growing in popularity due to some unique key features that TN display offer. For one,
TN TFTs remain very popular among competitive PC gaming communities, where accuracy and response rates can make the difference between winning and losing.
VA, also known as Multi-Domain Vertical Alignment (MVA) dislays offer features found in both TN and IPS screens. The Pixels in VA displays align vertically to the glass substrate when voltage is applied, allowing light to pass through.
Displays with VA screens deliver wide viewing angles, high contrast, and good color reproduction. They maintain high response rates similar to TN TFTs but may not reach the same sunlight readable brightness levels as comparable TN or IPS LCDs. VA displays are generally best for applications that need to be viewed from multiple angles, like digital signage in a commercial setting.
IPS (In-Plane Switching) technology improves image quality by acting on the liquid crystal inside the display screen. When voltage is applied, the crystals rotate parallel (or “in-plane”) rather than upright to allow light to pass through. This behavior results in several significant improvements to the image quality of these screens.
IPS is superior in contrast, brightness, viewing angles, and color representation compared to TN screens. Images on screen retain their quality without becoming washed out or distorted, no matter what angle they’re viewed from. Because of this, viewers have the flexibility to view content on the screen from almost anywhere rather than having to look at the display from a front-center position.
IPS displays offer a slightly lower refresh rate than TN displays. Remember that the time for pixels to go from inactive to active is measured in milliseconds. So for most users, the difference in refresh rates will go unnoticed.
Based on current trends, IPS and TN screen types will be expected to remain the dominant formats for some time. As human interface display technology advances and new product designs are developed, customers will likely choose IPS LCDs to replace the similarly priced TN LCDs for their new projects.
One of the most important aspects of any display you can understand is the panel technology being used. Specifications alone won’t give you the full picture of a displays performance, and we all know that manufacturers can exaggerate specs on paper to suit their marketing. With an understanding of the panel technology being used you will get a feel for the overall performance characteristics of the display and how it should perform in real terms. Our extensive panel search database helps you identify the panel technology (and manufacturer and part number where known) of many screens in the market. This article which follows will help you understand what the different panel technologies can offer you. A lot of manufacturers now list the panel technology as well in their specs, something which wasn’t included a in the past.
TN Film panels are the mostly widely used in the desktop display market and have been for many years since LCD monitors became mainstream. Smaller sized screens (15″, 17″ and 19″) are almost exclusively limited to this technology in fact and it has also extended into larger screen sizes over the last 7 years or so, now being a popular choice in the 20 – 28″ bracket as well. The TN Film panels are made by many different manufacturers, with the big names all having a share in the market (Samsung, LG.Display, AU Optronics) and being backed up by the other companies including most notably Innolux and Chunghwa Picture Tubes (CPT). You may see different generations of TN Film being discussed, but over the years the performance characteristics have remained similar overall.
TN Film has always been so widely used because it is comparatively cheap to produce panels based on this technology. As such, manufacturers have been able to keep costs of their displays down by using these panels. This is also the primary reason for the technology to be introduced into the larger screen sizes, where the production costs allow manufacturers to drive down retail costs for their screens and compete for new end-users.
The other main reason for using TN Film is that it is fundamentally a responsive technology in terms of pixel latency, something which has always been a key consideration for LCD buyers. It has long been the choice for gaming screens and response times have long been, and still are today, the lowest out of all the technologies overall. Response times typically reach a limit of around 5ms at the ISO quoted black > white > black transition, and as low as 1ms across grey to grey transitions where Response Time Compensation (overdrive) is used. TN Film has also been incorporated into true 120Hz+ refresh rate desktop displays, pairing low response times with high refresh rates for even better moving picture and gaming experiences, improved frame rates and adding 3D stereoscopic content support. Modern 120Hz+ refresh rate screens normally also support NVIDIA 3D Vision 2 and their LightBoost system which brings about another advantage for gaming. You can use the LightBoost strobed backlight system in 2D gaming to greatly reduce the perceived motion blur which is a significant benefit. Some screens even include a native blur reduction mode instead of having to rely on LightBoost ‘hacks’, providing better support for strobing backlights and improving gaming experiences when it comes to perceived motion blur. As a result, TN Film is still the choice for gamer screens because of the low response times and 120Hz+ refresh rate support.
The main problem with TN Film technology is that viewing angles are pretty restrictive, especially vertically, and this is evident by a characteristic severe darkening of the image if you look at the screen from below. Contrast and colour tone shifts can be evident with even a slight movement off-centre, and this is perhaps the main drawback in modern TN Film panels. Some TN Film panels are better than others and there have been improvements over the years to some degree, but they are still far more restrictive with fields of view than other panel technologies. The commonly quoted 170/160 viewing angles are an unfair indication of the actual real-life performance really, especially when you consider the vertical contrast shifts. Where viewing angles are quoted by a manufacturer as 160/160 or 170/160 that is a clear sign that the panel technology will be TN Film incidentally.
Movie playback is often hampered by ‘noise’ and artifacts, especially where overdrive is used. Black depth was traditionally quite poor on TN Film matrices due to the crystal alignment, however, in recent years, black depth has improved som
