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.

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.

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.

As you probably know, you can usually get a monitor cheaper online than at a brick-and-mortar store. Unfortunately, buying online also usually means buying blind. And with a TV or monitor, that can lead to disappointment.

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.

In conclusion, the type of panel to be used is determined by the purpose of the monitor. In photography, graphics design, video and picture edits, where the displayed colors, as well as the viewing angle and contrast, are of great importance, the IPS should be considered. If the refresh rate, price and the reaction time is needed more than the other characteristics, the TN panel should be considered.

However, an IPS panel can have a higher reaction and refresh rate, but this will lead to an increase in the cost of production as well as the cost of acquiring it. It might also lead to a great increase in power consumption.

For our PresentationPoint users and digital signage in general, we can transform this recommendation as follows. For advertising and public information screens e.g. in hotels: use an IPS panel. In areas where the graphics qualities are not that important, use a TN panel. Think here about information screens in factories.

The number of LCD (Liquid Crystal Display) panels available is vast but they can be separated into several different categories, based either on technology, construction method, or even individual brand.

Common applications can be for entertainment purposes, like watching videos and playing games, or doing technical creative work like picture editing where color accuracy is paramount.

After determining the application for your display you can start to identify which features need to take priority over others. Then you will be able to narrow your search and select the panel best suited for your use.

You get the highest performance at the lost cost. TN displays have evolved to the point where they have an incredibly fast response time, meaning they are great for entertainment purposes.

Regarding viewing angle, the TN display suffers particularly in the vertical direction; when watching a movie you must be sitting directly in front of the display to get the best picture.

Most TN displays can represent only 70% of NTSC, Adobe RGB and sRGB color gamuts, in some cases as little as 10 to 30% with the poorest quality displays.

When it comes to choosing a display for a creative application it is important to consider only a high-quality TN display as the color gamut will be higher.

The viewing angle in specific IPS screens has improved to the point where crystal-clear viewing is possible at 178 of the 180 degrees available to a user.

Contrast and blacks have also considerably improved. IPS panels do not lighten or show tailing light when touched, which can happen on TN panels; this is important for touch-screen devices such as smartphones and tablets.

However, as with all new technology, it is not perfect. The response times of IPS panels still falls behind those of TN technology. The cost of an IPS panel is also higher than that of a TN panel.

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.

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.

The LC molecules have a positive dielectric anisotropy and align themselves with their long axis parallel to an applied electrical field. In the OFF state (shown on the left), entering light L1 becomes linearly polarized by polarizer P. The twisted nematic LC layer rotates the polarization axis of the passing light by 90 degrees, so that ideally no light passes through polarizer A. In the ON state, a sufficient voltage is applied between electrodes and a corresponding electrical field E is generated that realigns the LC molecules as shown on the right of the diagram. Here, light L2 can pass through polarizer A.

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.

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

So, why is this important? A monitor’s panel technology is important because it affects what the monitor can do and for which uses it is best suited. Each of the monitor panel types listed above offer their own distinctive benefits and drawbacks.

Choosing which type of monitor panel type to buy will depend largely on your intended usage and personal preference. After all, gamers, graphic designers, and office workers all have different requirements. Specific types of displays are best suited for different usage scenarios.

The reason for this is because none of the different monitor panel types as they are today can be classified as “outstanding” for all of the attributes mentioned above.

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.

IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.

IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.

When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.

Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.

In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

On the flip side, however, TN panel technology tends to be ill-suited for applications that benefit from wider viewing angles, higher contrast ratios, and better color accuracy. That being said, LED technology has helped shift the perspective and today’s LED-backlit TN models offer higher brightness along with better blacks and higher contrast ratios.

The greatest constraint of TN panel technology, however, is a narrower viewing angle as TN monitors experience more color shifting than other types of panels when being viewed at an angle.

Today’s maximum possible viewing angles are 178 degrees both horizontally and vertically (178º/178º), yet TN panels are limited to viewing angles of approximately 170 degrees horizontal and 160 degrees vertical (170º /160º).

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

For general-purpose use, these shifts in color and contrast are often irrelevant and fade from conscious perception. However, this color variability makes TN monitors a poor choice for color-critical work like graphic design and photo editing. Graphic designers and other color-conscious users should also avoid TN displays due to their more limited range of color display compared to the other technologies.

TN monitors are the least expensive panel technology, making them ideal for cost-conscious businesses and consumers. In addition, TN monitors enjoy unmatched popularity with competitive gamers and other users who seek rapid graphics display.

Vertical alignment (VA) panel technology was developed to improve upon the drawbacks of TN. Current VA-based monitors offer muchhigher contrast, better color reproduction, and wider viewing angles than TN panels. Variations you may see include P-MVA, S-MVA, and AMVA (Advanced MVA).

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

Contrast ratio is the measured difference between the darkest blacks and the brightest whites a monitor can produce. This measurement provides information about the amount of grayscale detail a monitor will deliver. The higher the contrast ratio, the more visible detail.

These monitors also provide more visible details in shadows and highlights, making them ideal for enjoying videos and movies. They’re also a good fit for games focused on rich imagery (RPG games for example) rather than rapid speed (such as FPS games).

MVA and other recent VA technologies offer the highest static contrast ratios of any panel technology. This allows for an outstanding visual experience for movie enthusiasts and other users seeking depth of detail. Higher-end, feature-rich MVA displays offer the consistent, authentic color representation needed by graphic designers and other pro users.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

With the lowest cost and fastest response times, TN monitors are great for general use and gaming. VA monitor offers a step up for general use. Maxed-out viewing angles and high contrast ratios make VA monitors great for watching movies and image-intensive gaming.

IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Liquid Crystals (LCs) are used because of their unique ability to maintain a parallel shape. Acting as both a solid and liquid, LCs are able to react quickly to changes in light patterns. The optical properties of LCs are activated by electric current, which is used to switch liquid crystals between phases. In turn, each pixel generates an RGB (red, green, blue) color based on the phase it’s in.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

As a result, active-matrix technology was invented and transistors (TFTs) began being used to help liquid crystals retain their charge and change phase more quickly.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

Ultimately, budget and feature preferences will determine the best fit for each user. Among the available monitors of each panel type there will also be a range of price points and feature sets. Additionally, overall quality may vary among manufacturers due to factors related to a display’s components, manufacturing, and design.

If you’re interested in learning more about IPS monitors, you can take a look at some of these professional monitors to see if they would be the right fit for you.

Alternatively, if you’re into gaming and are in the market for TN panel these gaming monitor options may be along the lines of what you’re looking for.

main issue with TN is their lack of color consistency across screen because bad viewing angles so it don"t matter how good you calibrate such screen because most of image are will be screwed up. VA panels have similar issue and similarly are bad where color consistency matter

also most TN have smaller and less accurate gamut but it have to do more with cheaper backlight than with panel itself. Panel have nothing to do with gamut as colors are generated by backlight + filters not panel itself so it would pose no technical issue to make TN panel with eg. 135% NTSC 1976 other maybe that it would have no logical sense to do so. Anyway, most TNs can"t reproduce sRGB gamut and trying to use CMS can produce clipping artifacts that do not look very nicely

to really play with CMS (calibration and color managed software) you should get IPS/PLS type panel with wide gamut monitor or at least one which have larger gamut than sRGB. There is no going past it. Thankfully nowadays monitors that match those criteria are not very expensive

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.

Most gamers are aware of the fact that monitors come in different resolutions and screen sizes, or that monitors can have either a glossy or matte screen surface, and can offer other features such as 3D capabilities and 144HZ refresh rates.

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, phrases like “grey-to-grey response time” and “contrast ratio” are important to understand. There are also other specifications such as “color bit-depth” and “input delay” that are good to know as well.

This is the first question you need to ask yourself. Because, if you’re working with a budget of $150 or less for your monitor, your options will be much more limited than if you were working with a ~$500 budget.

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.

This kind of ties into the question above, but it is worth considering as well. As I mentioned above, if you are a serious gamer and you are playing competitive games where every split-second could be the difference between victory and defeat, you might want to forego better visuals for a better performing monitor.

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.

The other bit you ought to understand is that it is quite difficult, if not completely impossible, to find a monitor that is the best solution for every individual.

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

And taking into consideration the fact these screens come in larger sizes nowadays, the limited viewing angles can even affect people who are sitting right in front of the monitor.

The eyes, for instance, will perceive a different viewing angle if you look at the center of the screen instead of the peripheral regions of the monitor. In this instance, a color shade can be represented to be a different shade depending on its position on the screen. It may appear darker when it is on the upper side of the screen or lighter when it is towards the bottom.

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.)

One significant glitch of IPS displays is a glow or sheen on the monitor when viewing dark content. This glitch becomes more noticeable when you are viewing the monitor from wider angles.

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.

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.

Even if you’ve only taken a casual interest in a new monitor, it’s often impossible to tell the difference between the technologies vying for your attention, especially as they continue to evolve.

Take in-plane switching (IPS), for example. Why might you want a monitor with an IPS panel as opposed to another type of panel? To answer that, of course, you have to understand what an IPS panel monitor is — and how it differs from other monitor panel types.

Almost all monitor panels are variations of LCD technology, and in monitors with an IPS panel, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystals are arranged parallel to the surfaces — in other words, in the same plane. When the crystals receive an electrical signal, they reorient to produce an image.

IPS panel technology first became mainstream in 1996 and has been refined ever since. Its main objectives were to offer greater off-axis coherence — so that when the screen is viewed from an angle, the colors maintain their realism — and to provide superior color fidelity.

Twisted nematic (TN) technology is what first made LCD panels both practical and affordable. TN panels block their backlighting when they’re electrically charged, but when they’re not charged they “twist” to allow light to shine through. These panels require such low voltages to operate that they can conceivably run on battery power.

TN panel monitors are the oldest and most affordable LCD-based panel monitors — which naturally makes them a popular choice. As well as being budget-friendly, TN panel monitors may also have very fast response times and refresh rates, depending on the software being used.

On the downside, TN panel monitors have relatively poor color reproduction and quite restricted viewing angles. Viewed from radically off-axis, the TN panel monitor shifts its colors to the point of inverting them.

Vertical alignment (VA) panel monitors were developed specifically to address the shortcomings of TN panel monitors. As the name suggests, they feature vertically aligned liquid crystals that “tilt” when electrically charged, letting light shine through. VA panel technology is common among curved monitors.

VA panel monitors have far more realistic color reproduction than the TN equivalent, and offer more comfortable viewing from an angle. They’re also adept at creating deep blacks, and so offer better contrast ratios.

These two technologies each have their own strengths. IPS is recognized for its color accuracy and consistency, as well as its maintained performance when viewed from an angle. Alternatively, VA panel monitors can offer superior contrast ratios and fractionally faster response times.

Color reproduction: IPS panel monitors excel here, and anyone who requires the best color accuracy and consistency really has no better option than an IPS model. Support for professional color space technologies (such as Adobe RGB) also makes them a compelling option for any work that relies on color fidelity, such as the creative industry.

Viewing angle: A viewing angle of 178 degrees, both horizontal and vertical, serves even the most demanding use cases. Anyone who needs reliable color reproduction from any angle, such as video editors, photographers and graphic designers, will reap the benefits of an IPS monitor.

Response time: In the early days of IPS, input lag was a shortcoming, which was more than enough to put off serious gamers and other users who value response time. But IPS monitors’ response times have improved, to the point that only the most intense gamers (or people who value razor-sharp response times over visual experience) will argue against IPS.

Contrast ratio: VA panel monitors are a little more accomplished at delivering deep black, and therefore are a better choice if strong contrast is a priority. IPS panels are not far behind, though.

IPS monitor panels typically serve as compact flatscreens — like Samsung’s 24-inch S40UA — while VA panels are widely adopted for curved monitors, like Samsung’s 49-inch S95UA. Both panel technologies provide numerous benefits across all use cases and industries.
