ahva lcd panel factory

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

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

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.

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

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

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

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

If you’ve ever bought a monitor, you would know how vital the refresh rate, screen size, and 3D support are. However, there is another feature that can significantly impact the quality of your picture. And that is known as monitor panel type.

Are you aware of the monitor panel type? Well, if you’re not, we can help. In this article, you’ll find everything about a monitor panel and its types. This will help you select the right kind of monitor for your use. So, if you’re ready, let’s dive right in.

Panel type is a technology used in LCD monitors. Different panel types bring in various features and benefits. The most common panel types are TN panels, VA panels, and IPS panels.

The TN panel type is one of the most popular panel types that replaced CRT TVs. It’s better than the CRT TVs but comes with some disadvantages. Viewing angles being an example. The colors in a TN panel invert completely when you view it from an extreme angle.

Another disadvantage is the low color reproduction. The TN panels cannot display 24-bit true color and use interpolation for color shade stimulation. This leads to a low contrast ratio as compared to IPS or VA panels.

However, people still go for TN panels. It’s because these panels are cheap and affordable. If you don’t want many colors and great viewing angles, the TN panels can be significant. The TN panels also support refresh rates of 240Hz without any hassle.

You can think of VA panels as an advanced form of TN panels. These panel types offer a better contrast ratio. It’s the reason why TV manufacturers use it vigorously. You can commonly find a contrast ratio of 3000:1 in these panel types.

The VA panels also offer amazing viewing angles. The performance is way better than TN panels and similar to IPS panels. However, the response rate of VA panels is slower as compared to the TN panels. VA monitor with refresh rates of up to 240Hz is available, but it usually results in motion blur.

Unlike the TN panels, VA panels offer better color reproduction even if you buy lower models in this range. The VA panels are good for multiple average uses. You can play single-player games using this panel type or use it generally for watching TV.

IPS panels are the best panels available in the LCD panel technology. These panels offer better image quality, viewing angles, and color accuracy. When it comes to graphics design, where you need constant color reproduction and color accuracy, IPS panels are the best.

Also, the viewing angles you get with IPS panels are the best. It can even support a wide viewing angle of 178 degrees, which is quite impressive. So, if you care about the image quality and viewing angles, this is what you should go for.

Super PLS is similar to the IPS panel technology that Samsung developed. The manufacturer claims to produce better and wider angles as compared to previously available IPS panels. Also, they claim to generate about 10 percent more brightness as compared to the generic IPS displays.

The AHVA panels are also known for being similar to IPS panels and offer performance similar to PLS. The AHVA is an acronym that, when expanded, becomes Advanced Hyper Viewing Angle. As the name suggests, this panel type delivers a better and wider viewing angle.

IPS panels are the best when compared with the VA or TN panels. For everyone who needs better color accuracy, reproduction, and wider viewing angles, IPS panels are what you should prefer.

All of the above panel types come with their advantages and disadvantages. Choosing the best one can be easy if you know the purpose you need the monitor for. Here’s a briefly summarized view of all the panel types discussed above for your reference.

IPS, PLS, AHVA:All the IPS panel types are usually voted as the best because of the better image quality they deliver. However, it’s the price that keeps most people from buying a monitor with IPS panels.

VA Panels:VA panels offer a good contrast ratio, color reproduction, and viewing angles as compared to the TN and IPS panels.However, the response times are slightly lower as compared to TN and IPS panels. You may also experience color shifting in these kinds of panels. But the VA panels are easily available and affordable too.

TN Panels:These panels are easily available in the market and are the cheapest. You can also find the best response rates with these panels. However, the TN panels offer poor contrast ratio, viewing angles, and color reproduction.

IPS (In Plane Switching) panels are generally considered the best overall LCD technology for image quality, color accuracy and viewing angles. They are well suited for graphics design and other applications which require accurate and consistent color reproduction. IPS panels offer the best viewing angles of any current LCD technology, with wide viewing angles up to 178 degrees.

All these benefits raise IPS monitors to a higher price range compared to VA and especially affordable TN panel LCD displays. The response time of IPS is adequate, ranging from 6ms to 16ms with current panels. This is only slightly slower than TN panels. However, gamers should take this into consideration. Fast paced games may suffer from motion blur or ghosting with IPS panels that have a response time higher than 8ms.

S-IPS panels can often be identified buy a slight purple hue on blacks when viewed from a wide angle. There are currently few manufacturers using S-IPS panels in comparison to the other panels types making choices limited and they often carry a premium price tag. H-IPS is a newer variation of S-IPS with a different pixel structure that improves contrast ratios and lowers pixel pitch to provide better picture quality.

There are various iterations of IPS panels, for example: S-IPS, H-IPS, e-IPS and P-IPS. They are relatively similar regarding the technology they use, though H-IPS panels do have a slightly different pixel structure than the rest and the majority of e-IPS panels only offer 6-bit color depth. IPS LCD monitors are a suitable stopgap display technology until OLED monitors are commercially viable. If you"re in the market for a monitor that uses IPS technology you can review our comprehensive list of IPS monitors before choosing.

Super PLS (Plane to Line Switching) is a proprietary LCD panel type developed by Samsung that is very similar in design and construction to IPS panel technology. Samsung has made claims stating Super PLS panels have wider viewing angles and produce 10% more brightness than IPS displays while being cheaper to produce. The 27" Samsung S27A850D was the first LCD monitor released to make use of Super PLS.

Yet another proprietary "IPS-like" panel type that offers similar performance to PLS. Developed by AUO, AHVA is short for Advanced Hyper-Viewing Angle. The acronym can be slightly confusing as AHVA technology will sometimes be mixed up with Vertical Alignment (VA, see below) even though it makes use of In-Plane Switching (IPS).

VA (Vertical Alignment) technology such as S-PVA/MVA are middle of the road LCD panels. They offer better color reproduction and wider viewing angles than TN panels, but have slower response times. They are very similar to S-IPS on paper. They also offer large viewing angles and good color reproduction, though not as good as IPS panels. The response times are generally worse than TN or IPS panels and there have been reports of a few VA panels that suffer from input lag, so VA technology is not be the best choice for fast paced gaming.

VA panels have the advantage of higher contrast ratios compared to other panel types, which leads to better black levels. The biggest disadvantage of VA based panels is color shifting. Color shifting is when the image viewed from one angle changes or "shifts" when viewed from a slightly different angle, making various uneven brightness levels across the display. This bothers many users to the point they will not even consider buying a VA based panel, while other users don"t notice or aren"t bothered by the color shifting. Color shifts also cause a loss of shadow detail in dark scenes when viewed directly from the center.

VA panels are much easier to find compared to IPS since so many manufacturers utilize them for LCD monitors and other displays such as large HDTVs. They offer better image quality than TN at a lower price point than IPS panels. Update: IPS has recently exploded in popularity. They have now overtaken VA monitors in regards to availability and lower price.

TN (Twisted Nematic) panels are the most widely used panel type in the manufacture of LCD monitors. TN panels are cheap and offer excellent response times, making them perfect for fast paced gaming. The response times of current TN panels range from 2ms to 5ms. Unfortunately the color reproduction, viewing angles and contrast ratios of TN panels are the worst of any current LCD panel technology.

Unlike most 8-bit IPS/VA based panels, TN is only 6-bit and unable to display the full 16.7 million colors available in 24-bit true color. They can mimic the 16.7 million colors of 8-bit panels using a technique called dithering, but the results are unimpressive. TN panels have become popular with the average computer user because they are very inexpensive and currently dominate the LCD display market in availability.

S-IPS, H-IPS, Super PLS, AHVA and other IPS-type panels are generally considered the best all around panel type, but they are more expensive and very few are made. High end, expensive.

S-PVA/MVA/VA panels offer better color reproduction and viewing angles than TN panels, have slightly worse response times than TN or IPS, offer the best contrast ratios, may suffer from color shifting or input lag and have higher availability than IPS and Super PLS panels. Mid range, fair price.

TN panels are very cheap and have the fastest response times, but suffer from inferior color reproduction, contrast ratios and viewing angles. The majority of LCD monitors produced use TN panels. Low end, inexpensive.

Update: As of 2016, much of this information still applies, though prices of IPS-based displays have dropped and they"re more readily available. VA panels have also seen improvements to their responsiveness/input lag. Many users now view VA performance and image quality as on par or close to IPS. TN is still the cheapest and most used panel type with the best responsiveness, least motion blur and worst viewing angles/image quality.

Because panels from LG and Samsung are of higher quality and more durable than chinese manufacturers. Previously, it was possible to see the panel model in a dell monitor, now this is not possible. Why dell decided to hide it is not clear. I understand that there are different price segments and it is not profitable to install more expensive panels everywhere, but if you pay attention to different specialized forums, people choose a monitor not only by brand, but also by the installed panel. It is important.

First, to be clear, there is no “best” panel type out of these, as all have their respective advantages and disadvantages over the others. The information here pertains to general characteristics, as even panels of the same panel type will have some variance in characteristics (power consumption, backlight bleed, etc.) depending on the luck of the draw. Manufacturer tuning can also impact display output, affording some differentiating leverage to manufacturers sourcing from panel suppliers (which is effectively all of them).

Nostalgia or riddance aside, there are still some valid reasons to use a CRT monitor. When compared to LCD panels, CRT monitors can have higher contrast ratio, very low response time (which leads to non-blurred pictures even with fast movement on screen), and very little input lag, although LCD input lag can be largely negated. The downsides of CRTs are apparent, though: they’re large, heavy, consume more power, produce flicker, can produce audible, high frequency noise (although age plays into whether one can hear them or not), produce slightly distorted images, and produce harmful electromagnetic waves (in the form of x-rays), which requires that toxic materials such as lead and barium must be used as shielding to prevent detrimental health effects. CRT monitors are also notoriously hazardous to repair, given their large, active electrical coils that can measure upwards of 50,000 volts of electricity.

CRT displays are sometimes still used in medical, simulation, military, and government fields that have embedded the displays into control panels and machinery.

CRT monitors have largely gone out of production, and are rarely sold new (finding a used CRT is fairly easy), but their advantages temporarily lent themselves to some special uses. In regards to gaming, CRT monitors have historically been advantageous to use when gaming competitively due to very little motion blur and very little input lag. That being said, these advantages have faded with the progressive march of TN panels.

TN panels now have low motion blur (especially with lightboost or a similar technology), offer high refresh rates, low response times (1ms GTG in many cases), and are more than adequate even in the world’s most competitive games.

Ultimately, for the vast majority of users, the disadvantages of CRTs aren’t worth their limited gains, especially when TN panels meant for gaming more than adequately satisfy the needs of even competitive gamers.

TN panels have many benefits over the previously popular CRT monitors: lower weight, lower cost to produce, lower power consumption, they’re much thinner, offer clearer pictures, have no realistically achievable resolution limits, offer flexibility in size and shape, and the ability to eliminate flicker.

That being said, TN panels weren"t and still aren’t perfect, and compared to the previously popular CRT monitors, they’ve suffered from limited viewing angles, uneven backlighting, worse motion blur, higher input lag, dead/stuck pixels, and poor display in sunlight.

To be clear, many of these issues have been improved upon, but due to the underlying science of LCD TN panels, cannot be completely resolved. In fact, many of these issues -- like uneven backlighting, motion blur, input lag, and dead/stuck pixels -- are inherent issues across all LCD panel types. Poor viewing angles become a more pressing issue with larger displays, since the viewing angle when viewed straight on increases towards the outside of the monitor, thus causing more color distortion. TN panels do have the advantages of lower response times and higher refresh rates than other panel types/CRTs. TN panels are generally from 60Hz to 144Hz, offering substantially greater fluidity of gameplay with higher frequencies.

TN panels provide a good compromise between CRTs and other LCD panels as their traditionally low response rates, input lag, and high refresh rate make them comparable to CRTs for accuracy; TN panels also have the advantages of offering sharper pictures, widescreen output, lower weight, smaller physical dimensions, and higher resolutions compared to CRTs.

Still, compared to other LCD panels, TN panels suffer from poor viewing angles and worse color reproduction. Ultimately, for most gamers playing somewhat competitively to very competitively, TN panels are a good choice, but for those looking for a prettier and improved color experience, another panel type may be worth considering.

IPS (In-Plane Switching) was created to address the shortcomings of TN panels. IPS panels seek to solve TN panels’ issues of poor color reproduction and viewing angles. In this regard, IPS panels have largely succeed. Not only do they offer a higher contrast ratio (superior blacks), high color accuracy (which leads to IPS panels also generally looking less “washed out”), but IPS panels also have very little color shift when changing the viewing angles.

The tradeoff to this is that IPS panels have slower response times, higher production costs, higher power consumption, and lower possible refresh rates. IPS panels have traditionally been 60Hz, although, as with all monitors, they can be overclocked (results will vary). There have been improvements to IPS panels over the years, and slightly different revisions in the form of E-IPS and H-IPS, but ultimately the differences between these versions are inconsequential to gamers and those not involved in graphic design as a job.

Due to their worse response rates and lower possible refresh rates, IPS panels are generally considered to be worse for competitive gameplay and used more often when color is important, such as graphic design. For gamers who don’t play competitively and prefer breathtaking strolls in Skyrim instead of sweeping scrubs in CS:GO, an IPS panel should be a consideration for the next monitor.

PLS (Plane to Line Switching) are quite similar to IPS panels, so much so that they have the same advantages and disadvantages, with a couple extra minor advantages. PLS is produced by Samsung, who claims that compared to IPS panels, PLS panels have better viewing angles, a 10% increase in brightness, 15% decrease in production costs, increased image quality, and allow for flexible panels. Samsung’s PLS panels have been known to overclock well in monitors such as the QNIX 2710 in particular. Overall, PLS is basically Samsung’s version of IPS, as it is very similar in functionality (and even name). AHVA is also very similar to IPS and PLS, and differentiation between them is rare, although it should not be confused with the next panel type.

VA (Vertical Alignment) panels offer a solid medium between TN and IPS panels. VA was created to combine the advantages of IPS and TN panels, and largely did, although they did so with some compromise. That seems to be a theme in the world of monitors.

Compared to IPS panels, VA panels have the advantage of higher possible refresh rates. Although most are currently 60Hz, there are a few that are above 60Hz. VA has more advantages over TN panels than IPS, with better color reproduction, higher maximum brightness, and better viewing angles. VA panels do have the best contrast ratios of all panel types mentioned, but they also have the worst response times of the monitor technologies covered here. This causes blurring in fast-moving pictures and is disadvantageous to gaming.

For the use of gaming, VA is not the greatest option due to generally higher response time in comparison to other panel types; this slower response causes more motion blur, effectively eliminating its deployment for fast-moving titles. For a general work monitor, VA panels provide high contrast ratios, brightness, refresh rates, good color reproduction, and good viewing angles.

TN panels are another good choice for competitive gamers, as they support higher refresh rates, low response times, decent input lag, and high resolutions. Their bad viewing angles, color reproduction, and slight blurring compared to CRT monitors (due to higher response times) are all disadvantages, ones which cannot be easily fixed.

IPS panels solve the issues of TN panels, with better color reproduction and viewing angles, but do so at the cost of refresh rate and response time. IPS panels are especially useful for those not wanting to play too competitively, but want a beautiful/immersive visual experience. PLS and AHVA are similar enough to IPS to usually not be differentiated.

VA panels provide a good middle ground with better-than-IPS refresh rates and contrast levels, but have worse viewing angles and color production, although generally still better than TN. Response times are VA’s largest downfall, though, being slower than IPS and its variants and TN.

What’s best for you will depend on all of these items. For those wanting to play at a competitive level and who favor FPS or racing games, TN panels are best. Those wanting a more impressive and immersive experience may want an IPS (or similar variant, such as PLS), especially if working on artistic endeavors. Finally, those wanting a general monitor for work might consider a VA panel, although due to their higher response times, they won’t be good for gaming.

However, the most important part of your monitor is its display. Apart from having different manufacturers, monitors also have different types of display panels.

The most common display technology is the liquid crystal display (LCD). But if you want to buy a monitor, things can get pretty confusing after this. Because LCD panels are further categorized into different types.

The TN or twisted nematic monitor panel is the oldest and most popular monitor panel. Despite being old, the TN continues to attract users to this day. Monitors with the TN panels are cheaper than the IPS and VA panels.

The biggest advantage of the TN panel is its price. You can get a TN monitor panel with similar specifications to the IPS and VA but at a lower price.

Another advantage of the TN panel is its low response time. With response time as low as 1ms or 2ms, TN monitors can respond rapidly with changes in its images.

The lag in fast-paced games suffered by other types of monitor panels can be an issue for gamers as this could be the difference between losing and winning.

The images produced by this type of monitors doesn’t measure up to images from the IPS and VA panels. This makes TN monitors unsuitable for graphic designers and general color intensive tasks.

The TN panel is based on 6-bit color depth and this makes it unable to display 16.7 million colors. The IPS and VA panels which are based on 8-bit are able to display this number of colors.

This is one of the most popular LCD panels in monitors. In-Plane Switching (IPS) has been in development since the 1970s with different researchers working to improve on the limitations of the TN monitor panels.

The IPS panel also produces better images as a result of its superior color production. If you use your monitor for graphics or other media work, the IPS panel is the best option for you.

Another disadvantage of the IPS monitor panel is its high response time. The panel takes much more time to respond to changes in images than the TN panel.

This is why IPS panels usually have lower refresh rates than the TN monitor panels. It’s rare to find an IPS monitor with a refresh rate higher than 60Hz. This can be a real issue for gamers.

Vertical alignment (VA) panels were created to improve on the limitations of the TN monitors. The VA panels offer better color production, higher contrast, and wider viewing angles than the TN monitor.

This type of panel is suitable for graphic design work. It displays deeper blacks and static contrast ratios that are higher than other types of LCD panels.

Generally, the VA panel is in between the TN and IPS panels. The VA panel improves on TN’s and IPS’s weaknesses while not meeting up with their strengths.

In most cases, the IPS still produces better images than the VA. Likewise, TN has a faster response time than the VA panel. If you want a monitor in between the TN and IPS at the right price, then the VA is for you.

Another issue you can encounter with a VA panel is color shifting. This occurs when an image viewed from an angle changes when you view it from a slightly different angle.

Plane to Line Switching (PLS) panels are similar to the IPS panels. It’s a modification of the IPS panel to improve on its performance. It’s sometimes called the Super PLS panel. The PLS panel is made by Samsung.

The South Korean company claims that PLS panels have better viewing angles than the IPS panel, a 10% increase in brightness, and a 15% decrease in production costs. Added to this, there are claims of better image quality and the possibility of having flexible panels.

First of all, the PLS panel produces better images and color when compared to IPS and TN. This makes PLS a great choice if you’re a graphic designer, a video maker or involved in any other type of work that involves media content.

Even though PLS is cheaper than IPS, it’s still more expensive than the TN panels. If you’re looking for a cheap IPS, this could be the monitor for you.

The PLS has a low response time. But its response time is still higher than that of the TN. An average gamer will find PLS as a good option but a professional gamer may still decide to opt for the TN monitor panels.

Because the best monitor panel for me is different from the best monitor panel for you. This is due to our differences in what we need from a monitor.

Up to now, the most commonly used screen panels are TN, IPS and VA. Certainly you"ve heard of these before, in the process of getting to buy a monitor and obviously, the type of panel is an important piece of information that reveals a lot about how monitors work.

TN , which stands for Twisted Nematic, is the oldest of all LCD technologies. This technology refers to the twisted nematic effect, which allows liquid crystal molecules to be controlled by voltage. Although the actual operation of the TN effect LCD is a bit more complicated, basically the TN effect is used to change the alignment of the liquid crystal when applying the voltage. Therefore, when there is no voltage, the crystal is "turned off", the liquid crystal molecules are twisted 90 degrees and combined with polarized layers, allowing light to pass through. Then, when a voltage is applied, the crystals basically no longer twist and block the light.

IPS stands for In-Plane Switching and, like all LCDs, it also uses voltage to control the alignment of liquid crystals. However, unlike TN, the IPS LCD screen uses a different crystal direction, in which the crystals are parallel to the glass substrate surface. Instead of "twisting" the crystals to modify the amount of light passing through, the IPS crystals are basically rotated and this creates a lot of benefits.

There are many IPS variants on the market and the three major LCD manufacturers use different terms to describe their IPS technology. LG simply calls its technology IPS , very easy to understand for everyone. Samsung uses the term PLS (short for Plane-to-Line Switching ), while AU Optronics uses the term AHVA (short for Advanced Hyper Viewing Angle ). AHVA should not be confused with conventional VA screens. AHVA is a technology like IPS. LG"s IPS, Samsung"s PLS and AUO"s AHVA will be a bit different, but the basic principles all come from IPS.

In short, the TN panels are twisted, the IPS uses parallel and rotating alignment, while the VA panels align vertically and tilt the crystals. Now let"s dive into some performance characteristics and explore how each technology is different, as well as which is better by specific criteria.

So far, the biggest difference between the three technologies is in perspective. TN panels have the worst viewing angle, with significant changes in color and contrast in both directions (especially vertical). Usually the viewing angle is rated as 170/160 but in fact, you will get changes in the direction of the bad when looking at any point, except for the front. High-class TN panels tend to be a bit better, but overall this is a major weakness of TN.

The VA and IPS panels are both significantly better, of which IPS is best for overall viewing. The 178/178 viewing angle rating is a realistic reflection of what you can expect with IPS. There is not much change in color or contrast from any angle. VA performed very well in this regard but not as well as IPS, mainly due to the change in contrast in the corners outside the center. With VA and especially TN, there are some color changes and contrast when viewed at the corners, they are not suitable for the professional work about color as important as IPS panels. That"s why you see most professional-grade monitors use IPS.

In terms of brightness, there is no difference between these technologies because the backlight section determines the brightness, separate from the liquid crystal panel. However, there is a significant difference in contrast ratio, and this is what most people need to consider when determining what type of panel they need.

Both TN and IPS panels have a contrast ratio of about 1000: 1, although there were some differences in our testing. TN panels have the lowest contrast ratio when calibrated, ranging from 700: 1 to 900: 1 (with base panel) and up to 1000: 1 (with better panel type). IPS has a larger range, some panels have a low contrast ratio of 700: 1 like TN, however, the best ratio can push to higher levels than TN (1200: 1 for desktop and 1500 : 1 for some laptop screens).

Basic VA panels start with a 2000: 1 contrast ratio and the best level easily surpasses the 4500: 1 mark (typical ratio for most monitors is 3000: 1). The TV mainly uses VA panels and the contrast ratio may be even higher. It"s not uncommon to see the contrast ratio set to more than 6000: 1. So if you want true dark areas and high contrast ratios, you"ll need to choose a VA panel.

Although the IPS panels have a moderate contrast ratio, they experience IPS glow. It is the phenomenon of a clear white light appearing at an angle when viewing dark images. The best panels limit this exposure to a minimum, but this is still a problem on all screens.

Color quality is another difference that many people notice between TN screens and other panels. Color quality can be divided into two criteria: color depth or bit depth and color gamut. In both criteria, the TN panels tend to fall into a weaker position. Many TN monitors, especially the basic models, are actually only 6-bit types and use FRC (Frame Rate Control) to achieve standard 8-bit output. 6-bit panels are prone to color banding (display of incorrect colors), while original 8-bit panels have a "smoother" color gradient and therefore better color output.

Not all TN panels are 6 bits. The most advanced TNs are the original 8-bit types, but most TN panels will be only 6-bit types, even for the moment. If you want the original 8-bit screen, you"ll have to use IPS or VA, with more options.

For a 10-bit panel type, usually you will need to find an IPS panel. Some VA panels may own this parameter, but very rare. Most monitors you buy are 10-bit, but they"re actually 8-bit + FRC, only professional-grade monitors offer the original 10-bit experience.

This is another part where VA and IPS provide a superior experience. The best TN panels tend to be limited to sRGB or, in the case of the worst base panels, they don"t even cover the whole sRGB range. TN panels with a wider color range also appear, but they are rare.

VA panels usually start with the full sRGB range to a minimum and, depending on the model, this range may be wider. VAs use quantum dot film, typically from Samsung, which offers larger color gamut, about 125% sRGB or 90% DCI-P3. Most of the common VA monitors tested fall in the range of 85 to 90% DCI-P3. This is a good result, although the best level can reach 95% or higher.

IPS panels have the largest difference. Basic IPS displays tend to achieve 95% sRGB or lower, while most models fall within the full sRGB range. With high-end displays, often reserved for professionals, it"s not uncommon to see the full DCI-P3 and Adobe RGB range appear. Of all tested IPS monitors with a wide color range, the lowest DCI-P3 range is 93% and 95% is the typical number. This makes IPS the best technology in terms of wide color gamut.

Throughout most of this article, we talked about TN as the worst of the three options. Until now, TN has the ability to reproduce colors, contrast ratio and the worst viewing angle. But TN has a great advantage in speed. TN panels are the best option, both in terms of refresh rate and response time.

Currently, TN is the only panel type that can reach speeds of 240Hz at 1080p and currently 1440p. VA panels reach 200Hz for Ultrawide displays, however most 16: 9 models are limited to 165Hz. IPS panels also topped the list at 165Hz, although LG has the 240Hz option at 1080p.

Although IPS panels can refresh at 144Hz and above, the number of panels with high refresh rates is limited compared to both VA and TN. Almost every IPS screen, especially the advanced options for professionals, as well as the basic office monitor, is 60 or 75Hz. Meanwhile, a significantly larger number of VA panels, with a wide range of sizes and resolutions, will have high refresh rates. And the main advantage of TN is the super high refresh ability.

Another key point to consider is the response time, which governs the overall level of ghosting, blur, and overall clarity of a background. IPS and VA panels initially had very slow response time, but this has been greatly improved on modern panels, so the difference between these three technologies is not as clear as before. With that said, TN still retains a huge advantage here.

Most TN panels have a transition time of 1ms or even lower with some recently released options. The average time levels to convert from grayscale to gray are actually measured for TN panels that tend to be in the 2 - 3ms range. This makes TN the fastest technology in terms of response time.

IPS panels take second place in terms of speed, although the trend is similar to IPS, there is a big difference between the best and worst options of this type of panels.

High-end IPS screens, typically those with high refresh rates, can have a transition time of 4ms. This makes IPS works better than the best TN panels. However, basic IPS panels or models without overdrive feature will be close to 10ms, while mid-range options tend to be between 5 and 7ms.

VA panels are always the slowest of the 3 technologies. The fastest speeds measured are between 5 and 6ms, although typical numbers range from 8 to 10ms for gaming-grade monitors. VA panels also tend to be at least consistent in conversion. Some individual conversions can be very fast, while others are very slow.

Although many people may not realize the difference between VA 8ms and 5ms IPS panels, at least this is more clearly shown in motion. The sluggish VA panels also limit their actual refresh rate: The 144Hz panel has a 9ms response time, which actually delivers an image equivalent to the 110Hz panel. While most 144Hz IPS panels can switch faster, resulting in a true 144Hz experience. So this is a point to consider.

In short, TN panels are fast options and have the highest refresh rate, but they have poor viewing angles, as well as weak color performance and lowest contrast ratio. TNs are commonly used for ultrafast gaming monitors, as well as affordable desktop and laptop screens.

IPS is a mid-range technology. They often have the best color performance and viewing angle, response time, refresh rate, along with black levels and average contrast ratio. Thanks to the most advanced color output, IPS panels are the right choice for professionals, but you"ll also find them in basic displays, office monitors, most laptops and some Little gaming screen.

VA panels are the slowest option among the 3 technologies, but have the best contrast ratio and black levels to date. Color performance is not decent, but they still provide a significantly better experience than TN.

With the response time for the best modern VA panels up to the level of conventional IPS, along with extensive support for high refresh rates, VA technology is commonly used for gaming monitors. Basic VAs also tend to outperform TN and IPS panels of the same level, although VA is not used in laptops.

There is no exact answer to which screen technology question is the best, because each option has its own strengths and weaknesses. That is why all three coexist on the market to this day. However, if you want to get a recommendation, VA panels seem to be an attractive option for most buyers, especially gamers and casual users. Creative experts should opt for an IPS display, while those who need a super-cheap or ultra-high refresh rate for gaming should choose TN.

There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.AHVA IPS

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.8 bits

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.No

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.16777216 colors

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.W-LED

In order to choose the best monitor for your needs, it is very important to distinguish what kind of LCD panel interface type is in the monitor you’re looking at. The most common panels used nowadays are;

One of the types of panels that you will find in a computer monitor is a TN Panel. This stands for Twisted Nematic, and this particular type of LCD panel is generally the cheapest. They are the cheapest to manufacture among all LCD technologies, so they are the most commonly used in budget monitors.

If you are looking to game online, you will need a monitor with a higher refresh rate like that offered by a TN panel. Refresh rates are measured in Hertz (Hz), which defines how many times per second your screen can display new images.

The typical response time for a TN panel is less than 5 ms which is much faster than the 6 or 8 ms response time that other LCD displays have, such as vertical alignment or VA.

The biggest downside with these panels is often their viewing angles. On a TN panel, the viewing angles aren"t very good, and depending on how far off-center you are, the picture can begin to lose color and contrast.

TN panels also don"t support as wide a range of resolutions as IPS. This LCD monitor panel type has a poor contrast ratio when compared with other technologies such as IPS and VA. This results in an inability to display deep blacks and bright whites at the same time.

TN panels are manufactured by Samsung, LG, AUO, Chi-Mei, Chunghwa Picture Tubes, Hannstar Display Corporation, Sharp Corporation, CMI, Innolux, J-Tech Digital Imaging Co. Ltd, AU Optronics Corporation, etc.

A TN panel is a type of liquid crystal display (LCD) used in most LCD monitors and laptops. TN panels were the workhorse of the 1990s and early 2000s, but they were eventually replaced by their more-expensive cousins, the in-plane switching (IPS) and vertical alignment (VA) panels.

TN computer panels work by using two polarized filters, vertical and horizontal, to control the light that passes through them. The filters are arranged so that when the electrical current is off, light cannot pass through. When it"s on, it hits the twisted crystals to produce colors. The active layer is twisted to allow the light to pass through it, and this twist is controlled by electrical fields applied to the liquid crystal material.

It is worth noting that A TN panel is made up of millions of pixels, each pixel being red, green, or blue in color. The light from each pixel can be either on or off, so black is created when all the pixels are off and white when all are on. When all three colors are combined, any color can be produced. This arrangement is called RGB (red-green-blue).

A TN panel uses twisted nematic liquid crystals to form images. While not as desirable as other technologies, it does have several benefits worth considering when making a purchasing decision.They are mostly found in budget LCDs, as they are cheaper to manufacture and therefore sell for less.

TN panels have excellent response rates and refresh rates, typically 1 - 2 milliseconds and 50 – 75 Hz, respectively. This makes them ideal for high-end gaming

TN is the oldest and most common type of LCD panel, and it"s also the cheapest to produce. TN panels were the first panels to be introduced to the market, but they"re no longer as popular as they used to be. This is because TN panels have several downsides:The main disadvantage of TN panels is limited viewing angles, which can be extremely limiting in some cases. If you"re sitting straight in front of the monitor, everything is fine, but if you move to the side, then all colors shift and get distorted. That can be extremely annoying for graphic designers or architectswho work with color palettes, photographers who need exact color matching, etc. (see also

TN panels typically have lower contrast ratios than IPS displays do, so they don"t look as rich in color or dark black. So TN panels are usually not suitable for professional applications such as color-critical photo editingand graphic design.

Many gamers prefer TN panels because they provide a very fast response time and higher refresh rates. You can also find some with a refresh rate of 240Hz, which is even better.The Asus VG248QE is a 24-inch LCD display with a 1920 x 1080 resolution and a 1ms response time. It uses a TN panel, so don"t expect much in terms of viewing angle or color reproduction accuracy compared to an IPS display. But if you"re looking for a good 144Hz monitor, choose this one.

ViewSonic VX2458-MHD. It has a TN panel. The refresh rate of this monitor is 72Hz, which is standard. The response time of this monitor is 1ms. It also comes with 4 USB 3.0 ports, which is great if you plan on hooking up multiple devices, which is frequently used when trading. If you have a setup like that, you will also want to look at bezel less monitors, or frameless monitors, for your needs.

Another common type of panel is a VA panel. This stands for Vertical Alignment and is a step above a TN panel in terms of quality. Its name comes from the fact that light emitted from the screen"s backlight (see also LED monitors) is aligned vertically rather than being scattered horizontally and vertically as it is with a TN display.

VA panels provide high-quality images, wide viewing angles along with excellent contrast ratio and high refresh rates. These factors make VA panel monitors preferred for graphic design, photographers, video editors, and others who often work on their PCs.

VA panels are also better when displaying fast-moving images because they offer high refresh rates hence have less motion blur. Additionally, some panels have support for even 120 Hz refresh rates for ultra-smooth movement in games and movies.

Traditional LCD displays use two polarizing filters and liquid crystals (LCs) to create all the colors and patterns that we see on computer monitors and flat-panel televisions.

What are the Benefits of VA Panels?Image quality of VA technology is considered better than TN technology; text appears crisper, and images appear sharper and richer in contrast and color.

The big downside of TN panels is their response time. Most TN panels have a response time of 5-8 MS, which is fine for most people. However, if you"re mostly into competitive gaming or fast-paced action games like me that require quick reflexes, then this could be a problem.

We did some research and came up with a list of the best monitors with VA panels, and they are;ViewSonic VX2457-MHD. It is a24-inch monitor with a 1920 x 1080 resolution and covers 100% of the sRGB spectrum. It also has plenty of picture-enhancing features, including adjustable color settings and support for AMD"s FreeSync technology (see also affordable G Sync monitors).

This is the best LCD panel type. IPS stands for In-Plane Switching, and the biggest advantage over the other panels listed above is its wide viewing angles.

These screens are more expensive than TN panels but offer a greater contrast ratio, higher resolutions than their TN counterparts. They also support higher refresh rates, lower response time which makes them ideal for monitors larger than 24 inches.

These panels offer much more consistent colors, which makes them ideal for graphic designers or anyone who does any kind of color-critical work on their monitor.

IPS panels offer wider viewing angles than VA panels do, making them better suited for use in public spaces such as retail stores or airports where you can expect people will be walking by your TV from both sides.

The contrast ratio of an IPS panel is higher than that of TN panels. The contrast ratio of a display refers to the difference between the darkest black and the brightest white that the display is capable of producing. This can be an important factor in overall display quality, depending on how you use your laptop or desktop monitor.

Some manufacturers that specialize in IPS panel interphases include Samsung, LG, and even Mac Apple. Also, almost all Dell monitors use IPS panels. However, there are plenty of other high-quality manufacturers that also offer IPS panels for you to choose from.

In a liquid crystal display (LCD), light passes through a pair of polarizers. Each polarizer is made of a long chain of molecules, each oriented in a different direction; one vertical, the other horizontal.

In an IPS LCD panel, liquid crystals are aligned so that both polarizers face the same way—horizontal. Light from behind the panel passes through one polarizer and then bounces off onto a second polarizer before reaching your eyes. This design makes IPS LCDs nearly as bright as VA panels and much brighter than TN panels without sacrificing contrast ratio or color accuracy.

If you"re looking for a new monitor, IPS panels may be the right ones for you. Here are some of their most important benefits:It allows for wider viewing angles. This is very useful for monitors used at work that involve customer service, where the monitor may be viewed from many different angles.

The IPS LCD displays are also characterized by their high degree of brightness and contrast, which makes them ideal for outdoor use, among many other features.

The typical lifespan of an IPS panel is around 100,000 hours, which is more than enough for even heavy users to get their money"s worth from their monitor.

They have great color reproduction. Many people who are serious about a photo or video editing are drawn to IPS panels because they offer superior color reproduction possibilities when compared with TN panels.

The main disadvantage of IPS panels is that they are more expensive than TN panels. The cost of an IPS panel will typically be $10-$20 higher than a comparable TN panel.

Today, the majority of flat-panel monitors use in-plane switching (IPS) technology. Best monitors that have IPS panels include;Samsung U28E590D 28-Inch 4K UHD Monitor. If you love gaming, then this is the product for you; it comes with AMD FreeSync, which proved successful in eliminating screen tearing since being introduced as VSync, as this post explained.

Also, bear in mind that if it is a flat panel display with a 1080p resolution or higher, you can refurbish it and resell it after using it. Older monitors with lower resolutions may not be worth much.

It offers a much higher resolution than conventional LCD and can be used to manufacture large panels. It"s an innovative display technology that has the potential to change the face of consumer electronics.

There are 3 main types of LCDs; VA (Vertical Alignment), TN (Twisted Nematic), and IPS (In-Plane Switching). All these technologies have been used for over 10 years and have their own pros and cons. However, they have reached their upper limits in terms of resolution and other features, and it"s nearly impossible to increase them any further. That"s where Super PLS-Plane to Line Switching comes in.

Super PLS-Plane to Line Switching offers resolutions as high as 8K, has wider viewing angles, and is brighter. The image quality presented by this technology is said to be much better than traditional LCDs, and it could potentially disrupt the current.

The Nano IPS panel technology adds a layer of nano-particles to the backlight in order to transmit the screen"s picture more efficiently and reduce the chances of image retention.

Advanced Hyper-Viewing Angle (AHVA) computer display was developed by AU Optronics Corp. It is a type of LCD that can be seen clearly even from the most acute angles. Through the process of strengthening the polarizing plate, it can help minimize the reflection ratio to less than 1%. The viewing angle is about 178 degrees.

This technology was initially applied in television and notebook screens by AU Optronics Corp. The company claimed that AHVA could be seen clearly from all angles, which is better than VA and IPS technologies by 30% and 20%, respectively.

AHVA also provides a greater range of colors which makes images appear to pop off the screen. And it gives better performance outdoors, so you get a great view no matter whether it"s sunny or cloudy.

Most LCDs (liquid crystal display) monitors are now manufactured with an anti-glare coating to reduce the effect of ambient light reflecting off the screen. Anti-glare coatings can reduce reflections by 25 to 70%.

VA panel is better thank IPS. Although IPS panels have a contrast ratio of 700:1 to 1500:1, they are still inferior to VA panels. The majority of VA monitor panels have contrast ratios above 2500:1, and some even reach 5000:1 or 6000:1. Even local dimming is used by more recent monitors to obtain even greater contrast ratios.

Yes, IPS is better than OLED. The main benefit of IPS panels is their increased brightness, particularly when combined with a tiny LED backlight. OLED displays are often limited to brightness levels of roughly 1,000 nits, while mini LED displays can reach peak brightness levels of around 2,000 nits.

PLS (Plane to Line Switching) panel in an IPS-type panel made by Samsung; All IPS-type panels, such as Innolux’s AAS, AUO’s AHVA and LG’s AH-IPS and Nano IPS offer excellent color accuracy and wide viewing angles.

PLS stands for Plane to Line Switching and is produced by Samsung, who claims that a PLS panel offers 10% more brightness, better viewing angles, lower production costs (about 15%), better image quality and the possibility of having flexible panels.

There are several variations of IPS panels, such as AU Optronics‘ AHVA (Advanced Hyper-Viewing Angle) panels. New AHVA panels are usually faster than other IPS panels but don’t have as wide color gamut.

In reality, most people don’t differentiate between IPS, AHVA and PLS since they are pretty much alike, which is why they are categorized under a single entity and simply called ‘IPS.’

Overall, whether a monitor has an IPS, PLS, or AHVA panel shouldn’t be the deciding factor when searching for a new display. You should check each monitor’s color gamut, brightness, response time and other specifications to determine which monitor’s panel is better.

2014 IT needs better than the first half of the expected class panel, liquid crystal display panel plant supplied by the original panel to reduce the impact, a shortage phenomenon. Meanwhile, the supply chain industry, though not think the overall market demand to grow, but the brand in the industry pushing products to develop higher-order, wide viewing angle, high-resolution models penetration continues to rise.

According to industry statistics quoted by various market research, said the third quarter of 2014 LCD Monitor Brand Factory whole wide viewing angle product penetration has reached 30%. The larger the size, the higher the permeability of wide angle models, only 7% 20 inches or less wide viewing angle ?? product, but more than 21.5 inches wide-screen models of the wide angle product penetration rate of 45%, 27 inches wide screen above models, wide viewing angle product penetration as much as 7 percent.

Related industry, said liquid crystal display panel with laptop and other IT panel demand is indeed better than originally thought, it is estimated AIO PC LCD monitor with 160 million expected to watch over panel demand in 2014, 2015 have the opportunity to grow to 170 million, small increase of 2 to 3 percent, notebook panel in 2015 is also expected from about 170 million liters 190 million, annual growth more than 1 percent.

LCD monitor brand industry, said basically the mainstream size or small-size aircraft market, price competition has reached the limit, the price has to kill to low, and use a wide viewing angle and high resolution panel products, still due to panel makers, system works, etc. profit considerations, concentrated in large-size models, especially the 21.5 inches or more, and to observe all the brands in the industry recently introduced high-order new products, but also mostly concentrated in the 24, 27-inch large-size liquid crystal display.

Focus market demand continued to be optimistic, even more willing to plant the brand launched 4K resolution, wide viewing angle, and surface design and other specialty products, high-end LCD monitors also keep up with the pace of development of LCD TVs. According to research tune WitsView survey in 2014 in the third quarter before wide viewing angle LCD monitor penetration plant includes three brands Dell, LG Electronics (LG Electronics), BenQ, the follow-up in the fourth quarter as a whole have a chance wide angle penetration continues to rise , will observe other low permeability to promote brand factory condition.

According to its statistics, August performance LCD panel market demand is not bad, overall shipments came to 1,334 million pieces, month by 4.8%. Among them, the continent and the electrical panel makers BOE Panda 2-digit monthly growth rate, respectively, 21.5% and 33.3%. BOE size 23.8 inches in the new monthly shipments to break 100,000 mark, and 23.8 inches in the BOE, Taiwan factory AUO and LG Display (LG ?? Display) force arch, the market outlook is good.

Related to the supply chain industry, said, in general, the liquid crystal display market size is not easy to grow, such as OEM manufacturers from AOC (TPV) and other leading manufacturers shipments and it seems to data released estimates, the overall LCD market is still a year continued to decline, an estimated 2014 annual market size of approximately 136 million units in 2015, only about 132 million units in 2017 is estimated to decline to a level of only 128 million units.
