lcd panel va quotation

A wide variety of va lcd panels options are available to you, such as original manufacturer, odm.You can also choose from tft, ips and standard va lcd panels,

Contrary to what you may think, not all LCD TVs are built around the same core panel technology. They can actually have at their hearts one of two really quite different technologies: VA or IPS.

Each, as we’ll see, has its own distinct advantages and disadvantages – so much so that we personally think the type of panel a particular TV uses should be presented right at the top of its specifications list, rather than typically left off altogether. Especially as some brands have been known to actually mix and match VA and IPS panels at different screen sizes within the same TV series.

The VA initialism stands for Vertical Alignment. This name is derived from the way VA panels apply voltage to vertically aligned liquid crystals that have been mounted perpendicularly to the panel’s glass substrate, making them tilt as required to let the necessary amount of light through for each image frame.

The main advantage of VA panels is contrast. Their perpendicular crystal alignment provides greater control over the light passing through each pixel, meaning dark scenes and dark areas look less grey / enjoy better black levels.

The extent to which this strength is exploited can vary greatly between different manufacturers, and depends on any number of secondary factors. The type and position of LED lighting a particular VA screen might be using can have an impact, for instance. There are multiple variations on the VA theme available from different manufacturers, too. As a basic principle, though, black levels and contrast are consistently and often considerably better on LCD TVs that use VA panels.

Because of their ability to control light better, high-end VA panels generally deliver more brightness in real world conditions than IPS ones do. This further enhances their contrast capabilities, and arguably makes them more consistently able to do fuller justice to the wider light range associated with high dynamic range technology.

Being able to deliver dark scenes with relatively little overlying low-contrast greyness additionally means that VA panels tend to achieve more consistent colour vibrancy and toning.

VA panels for use in LCD TVs come from a number of panel manufacturers, including Samsung Display (which makes a so-called SVA variant) and AU Optronics (which makes an AMVA variant). TV brands are able to buy in panels from these and other VA panel manufacturers as they see fit.

Samsung Electronics is the most consistent user of VA panels in its LCD TVs. In fact, until recently pretty much every Samsung TV at every price level used a VA panel. For the past couple of years, though, IPS panels have unexpectedly cropped up in one or two parts of Samsung’s TV range, including 2021’s high-end QN85 series.

Sony predominantly uses VA panels on its most premium TVs, but it also habitually mixes IPS and VA panels across its wider mid-range and entry level LCD ranges. The same goes for most of the other big brands, too, including Panasonic and Philips.

IPS stands for In-Plane Switching. Like VA panels, IPS panels work by manipulating voltage to adjust how liquid crystals are aligned. Unlike VA, though, IPS panels orient their crystals in parallel with (rather than perpendicular too) the glass substrates present in every LCD panel, and rotate their crystals around to let the desired amount of light through rather than tilting them.

By far the biggest and most talked about advantage of IPS technology is its support for wider viewing angles. In fact, one way of identifying IPS panels has traditionally been to look for quoted viewing angles of 178 degrees.

When we talk about wide viewing angle support in relation to LCD TVs, we’re talking about how much of an angle from directly opposite the screen you can go before the picture starts to lose contrast, colour saturation and, sometimes, brightness.

With VA panels the angle you can watch them before the picture starts to deteriorate sharply can be really quite limited – as little as 20 degrees off axis. While we’d say the 178-degree claims for regular IPS panels are rather exaggerated, you can typically sit at a significantly wider angle than you can with VA and still enjoy a watchable picture.

We’ve even seen occasional evidence of the edges of really big (75-inch plus) VA screens suffering from the technology’s viewing angle limitations when viewed straight on, whereas this never happens with IPS technology.

The VA/IPS viewing angle situation is muddied a little by the introduction into a few high-end VA TVs of wide angle technologies based around filters or sub pixel manipulation. These technologies can be associated with other problems, though, such as reduced resolution, and can still struggle to suppress backlight blooming around stand-out bright objects with LCD TVs that use local dimming backlight systems.

Traditionally IPS panels have been associated with – on high-end screens, at least – wider colour gamuts than VA panels can readily manage. They retain this colour gamut better, too, when viewing the screen from an angle. This is why many professional designers, for instance, have tended to prefer IPS technology to VA. There can be some pretty extreme variance in the range of colour supported across different IPS price points, though, and improvements in premium VA solutions – especially the widespread use of Quantum Dot technologies – have largely evened things up, at least at the premium end of the VA market. In fact, with dark scenes, at least, IPS’s issues with black levels and ‘grey wash’ effect can give good VA panels a colour advantage.

There was a time when IPS technology was considered to have an edge over VA when it comes to response time, leading to less motion blur and improved gaming reaction times. These days, though, we’re seeing pretty much identically low input lag measurements (between 9.4 and 10.4ms) from both VA and IPS TVs.

As with VA, there are different variations on the basic IPS theme made by different panel manufacturers. LG Display is by far the biggest manufacturer of IPS LCD panels for TVs, but AU Optronics also makes them, as well as, more surprisingly, Samsung – though some of the non-LG Display IPS products seem to be more focused on PC monitors than TVs.

Given how dominant LG Display is in manufacturing IPS LCD panels, it’s not surprising to find that pretty much every LCD TV LG Electronics makes features an IPS panel at its heart. Other TV brands that use IPS panels on at least a few of their TVs each year include Panasonic, Philips, Sony and Hisense. In fact, the only big brand that has tended to shun IPS is Samsung (perhaps because of arch rival LG Display’s dominance of the IPS market).

As noted earlier, it can be frustratingly difficult to determine whether a TV is using VA or IPS technology. Sometimes it is mentioned in the specifications list on a manufacturer’s website – but more often it is not.

If you’re able to actually get your hands on an LCD TV, try knocking gently on its screen. If it’s an IPS panel it will feel solid and the picture will only be slightly affected – or completely unaffected – by the impact of your knocks. If it’s a VA panel, the picture will distort quite noticeably around points of impact.

It’s tempting to assume that any TVs with obviously low contrast are IPS while any screen with a narrow viewing angle is VA. As well as depending on having a wide experience of lots of panels, though, there’s just too much variation in the high and low-end fringes of each technology for this approach to be reliable.

Arguably your best bet is to check out a TV model you’re interested in on an industry website called Displayspecifications.com(opens in new tab), which includes usually reliable information on the core panel of pretty much every TV released.

You might want to consider IPS TV if your room layout means one or more viewers regularly find themselves having to watch the screen from a wide angle (though don’t forget that a small number of high-end VA TVs feature wide viewing angle technology). IPS’s black level limitations tend to be less obvious in bright rooms too, if that fits with the sort of environment your TV is likely to be used in for the majority of the time.

Our long experience of testing VA and IPS TVs, though, has led us to conclude that in general, the sort of person most likely to be turning to us for buying advice will be happier with an LCD TV based on VA technology.

VA’s ability to deliver typically much deeper, more convincing black levels and more HDR-friendly contrast helps them deliver a much more consistent and immersive modern AV experience. Especially if you’re the sort of person who likes to dim the lights for serious movie or TV viewing nights.

Vertical alignment (VA) is a type of LCD panel technology that when no electric current is running through, enables liquid crystal cells to naturally align vertically between two substrate panes of glass, blocking the transmission of light from the backlight.

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.

Liquid Crystal Display (LCD) screens are a staple in the digital display marketplace and are used in display applications across every industry. With every display application presenting a unique set of requirements, the selection of specialized LCDs has grown to meet these demands.

LCD screens can be grouped into three categories: TN (twisted nematic), IPS (in-plane switching), and VA (Vertical Alignment). Each of these screen types has its own unique qualities, almost all of them having to do with how images appear across the various screen types.

This technology consists of nematic liquid crystal sandwiched between two plates of glass. When power is applied to the electrodes, the liquid crystals twist 90°. TN (Twisted Nematic) LCDs are the most common LCD screen type. They offer full-color images, and moderate viewing angles.

TN LCDs maintain a dedicated user base despite other screen types growing in popularity due to some unique key features that TN display offer. For one,

Refresh rates and response times refer to the time it takes pixels to activate and deactivate in response to user inputs; this is crucial for fast-moving images or graphics that must update as fast as possible with extreme precision.

VA, also known as Multi-Domain Vertical Alignment (MVA) dislays offer features found in both TN and IPS screens. The Pixels in VA displays align vertically to the glass substrate when voltage is applied, allowing light to pass through.

Displays with VA screens deliver wide viewing angles, high contrast, and good color reproduction. They maintain high response rates similar to TN TFTs but may not reach the same sunlight readable brightness levels as comparable TN or IPS LCDs. VA displays are generally best for applications that need to be viewed from multiple angles, like digital signage in a commercial setting.

Based on current trends, IPS and TN screen types will be expected to remain the dominant formats for some time. As human interface display technology advances and new product designs are developed, customers will likely choose IPS LCDs to replace the similarly priced TN LCDs for their new projects.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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