When choosing a new computer monitor, the type of panel used on the monitor is important information that shows a lot of information about how the monitor works and functions. The most common types of display panels to date are TN, IPS, and VA. It is a layer of liquid crystal that determines the intensity of the light passing through the backlight and in what colors red, green or blue. To control this density, a voltage is applied to the liquid crystals, which physically moves the crystals from one position to another. How these crystals are positioned and how they move when voltage is applied is the fundamental difference between TN, VA, and IPS.
< Released Our main explanation of display technology and the difference between TN vs. VA vs. IPS was nearly three years ago, and while most of this information remains accurate to this day, we see IPS screens being introduced faster and also revolutionizing VA panels, especially Samsung Odyssey gaming monitors. We've also tested over 100 monitors since then, so we have more ideas to share on performance.
So, before we focus on the individual characteristics of each technology and how to focus them, it's an overview. They are running.
TN is the oldest LCD technology and stands for twisted nematic. This refers to the twisted nematic effect, an effect that allows the liquid crystal molecules to be controlled by voltage. While the actual operation of the LCD with the TN effect is a bit more complicated, the TN effect is mainly used to change the liquid crystal when voltage is applied. When there is no voltage, and therefore the crystal is "off", the liquid crystal molecules twist by 90 degrees and, in combination with the polarizing layers, allow light to pass through. Then when voltage is applied, these crystals are not fundamentally twisted and block the light.
VA stands for vertical alignment. As the name suggests, this technique uses vertically balanced liquid crystals that tilt when light is applied to allow light to pass through. This is the main difference between IPS and VA: with VA, the crystals are perpendicular to the substrates, while with IPS, they are parallel.
< Homogeneous alignment VA (vertical alignment) described above
IPS stands for switching planes and, like all LCDs, uses voltage to control the alignment of liquid crystals. Unlike TN, IPS LCD displays use a different crystal orientation, in which the crystals are parallel to the glass layers, hence the term "surface". IPS crystals, instead of rotating the crystals to change the amount of light that passes through them, are essentially rotating, and this has many advantages. You will also see different brands depending on the maker of the board. For example, AU Optronics uses "AHVA" to refer to an IPS panel, not a VA panel. Samsung uses PLS, while brands like LG simply use 'IPS'. Then on the VA side we have Samsung AU Optronics "AMVA" and "SVA" among others.
In short, TN panels damage, IPS panels use parallel and spin alignment, while VA panels use vertical alignment. Alignment Now let's look at some of the performance features and differences between each technology and in general, which technology is best in each category.Viewing Angles
The most immediately obvious difference when viewing a TN, IPS, or VA panel for the first time is the viewing angle. This is an area that has not changed significantly since the introduction of these technologies. The viewing angle is usually 170/160 degrees, but in reality very bad changes will occur when looking anywhere except for the dead center. Advanced TNs are somewhat better, but overall this is a huge disadvantage for TNs and can affect the productivity experience, as everything changes with color effect accuracy for things like photo editing.
VA panels and IPS are better Notable in viewing angles, overall IPS panels provide the best overall experience here, you'll usually see 178/178 ratings for viewing angles, and while you can still see color and lighting changes at off-centered angles, it's less noticeable than on a TN dish. Of all the IPS panels we've looked at over the years, I find the majority have a great viewing angle, which isn't a big deal for modern IPS screens.
< VAs are Also good but not as good as IPS and can have higher contrast than IPS. But what affects VA viewing angles even more is the fact that many VA monitors today are curved, reducing any introduction to the viewing angle curve. When choosing between IPS and VA
< /p> Brightness and contrast
Since the liquid crystal layer is separate from the backlight layer, there is no technical reason for TN, IPS, or VA displays to differ in brightness. Of the 100 screens we tested with our latest test suite, the average SDR brightness of the IPS panels was 385 nits, compared to the TN's 367 nits and 346 nits — so there's not much difference.
Contrast ratio, on the other hand, is where another big difference happens. TN panels have the worst contrast ratio, while the torsion technology is not very good at producing deep blacks. In most cases, you'll see a contrast ratio of around 1000:1, but typically after calibration these numbers are in the range from 700:1 to 900:1. Among the monitors we tested, the average TN has a contrast ratio of 872:1, Which is poor, so if you want rich blacks and blacks - you might just buy an OLED, but if you buy an LCD, don't get one. A TN. In the worst case - particularly the current set of LG IPS nano panels - you don't see contrast performance with regular TN at a ratio of less than 1000:1. However, outside the worst case, width contrast is at 1000, 1 or higher, with some getting better. The examples go to 1500:1, which is about the ceiling I've seen for IPS. Among the IPS panels we tested, the average contrast ratio was 1037:1, which is 19% higher than the average TN contrast.
If you really want the LCD to produce a deep black, you need to use a VA panel. The design of these panels is more favorable to the contrast ratios, which typically start at 2000:1, than even the best IPS options.
We've scaled VAs to 5,000:1, and some TVs can do more. Normal contrast ratios are a little wider than the other two technologies, but when manufacturers quote an aspect ratio of 3000:1 for their VA monitor, they are usually correct - on average, we measure a contrast ratio of 2898:1 for VAs. We got it. With that said, you can see that VAs usually use IPS or TN 2.5 to 3 times better at producing black, which is great for night scenes.
< Often They ask if this difference in contrast ratios really matters. Almost all monitors use a matte anti-glare coating that can effectively reduce contrast in brighter viewing environments. So if you use your screen during the day or under artificial light, the difference between TNs, IPS, and VAs will be less noticeable in contrast ratio. But if you usually use your screen in a darker environment, such as playing with the lights on or conducting an anonymous browser session at night, you can easily see the huge advantage of plug-ins in this area.
< It should be noted It also notes that while IPS panels are the center of contrast, they suffer from a phenomenon called "IPS glare," where a white glow appears when dark images are viewed at an angle. The best panels show the lowest brightness, but it's still a problem with all screens of this type and can vary between separate units. Color quality
Before discussing TN vs. VA vs. IPS, we spent some time talking about the difference between TNs, VAs, and IPS in bit depth - or the difference between 6-bit panels. , 8-bit and 10-bit. But these days we feel that the vast majority of monitors are native 8-bit panels, except for a few low-end 6-bit panels and a few high-quality 10-bit professional panels.
It is still the case that most monitors advertised as "10-bit" or "billion colors" are not true 10-bit panels, but differ in FRC or ditering and type of LCD panel technology. Little.
There isn't much difference between today's LCD types when it comes to covering "standard" color spaces like sRGB or Rec. 709, which is used by default in Windows and is widely used for video content.
< Even Panels TN, which has historically had "worse" color quality, nowadays buys more than 95% of the sRGB color space of at least any screen. Manufacturers like to punish buyers of cheap laptops. It's rare for a desktop screen to be below 90% sRGB, and you definitely shouldn't buy one if you have one.
For real 10-bit boards, you should usually look for IPS boards, which make up the majority of the original 10-bit boards. Some VA boards can do this, but it's rare. Most monitors you buy that are claimed to be 10-bit are actually 8-bit + FRC, and only top-tier professional monitors have a 10-bit experience.Coloring
The main differences between TN, IPS, and VA for color quality these days include a wider range such as DCI-P3, Adobe RGB, or Rec. 2020. DCI-P3 and Rec. 2020 is important for HDR movies and games, while Adobe RGB is popular for working with large images.
In the case of gaming monitors, which are most monitors we test, it is unusual for TN monitors. Transcends the sRGB color space and creates a wide range of colors. We've seen it occasionally, while DCI-P3 coverage exceeds 92% at best, but most TN displays are the standard range for SDR content.
We measured up to 97% DCI-P3 and above. 99% Adobe RGB on the same board - usually a premium model from AU Optronics - results in excellent recording. The 2020 coverage of over 80% makes IPS the most, or sometimes the only, technology suitable for broad color jobs like video or photo editing, and this is the technology I choose to do it with. Read rate
Fast talk time While there was a clear difference between the previous technique: TN was the fastest, IPS was in the middle, and VA was the slowest. In 2021, this is no longer the case, and every technology is becoming less and less distracting. Historically, almost all TN models had the highest refresh rate on the market, but this is no longer the case. TN, IPS, and VA displays are currently available at 240Hz or sometimes more than 240Hz, including resolutions like 1440p.
< Most screens The refresh rate on the market today is capable of 1080p 360Hz and uses IPS panels from AU Optronics, not TN. There is less demand for TN panels these days compared to other types of panels, so a lot of effort has been put into developing high-end models instead of IPS. This makes IPS the best upgrade technology at the moment, with all three technologies available at 1440p 240Hz. There is no longer a clear difference between the TN and the rest of the claimants today due to the high driving speed of the LG Nano IPS and the new generation of Samsung VA.
The fastest TN boards we've used. Our current and accurate test method is able to reach a mean of 4ms with a cumulative deviation of about 400. The cumulative deviation shows us that the screen response time is close to the ideal immediate response and also shows the balance between response time and redundancy. The HP Omen X 27 is definitely a fast monitor with 1440p 240Hz specs. However, the Samsung Odyssey G7 and G9 are actually quite a bit faster, with response times ranging from 3.4 to 4.0 ms and a cumulative deviation of less than 400.
This puts today's best VA monitors a little ahead About one of the best TN monitors we tested, which we certainly couldn't say a few years ago. With these new panels, Samsung solves the annoying dark surface contamination that was an issue in the previous generation of VA panels and gives the latest VA panels an overall experience similar to the best LCD screens.
Meanwhile, in the IPS camp, the best IPS panels are a bit slower than VA and TN panels, but are still very competitive with today's best panels. The fastest thing we saw was an average response time of 4.5ms with a cumulative deviation of about 460. That's less than a 20% discount on other top technologies and gives us very little difference in 2021 between the three types of LCD panels at best. Compared to the best.
However, this latency argument is only applicable to high-end monitors. Currently in the mid- and mid-market, the performance difference between TN, IPS, and VA is more traditional. TN displays still run pretty fast, running in the 4ms range even with 1080p 144Hz motherboards. Basically, if you buy a TN in any market segment, you know it's going to be fast.
The next step down IPS is in the lower price segments and performance varies slightly depending on the exact model. This is because mid-range and entry-level IPS monitors are more likely to use the latest generation panels, which are no faster than today's best monitors. However, performance between 6 and 9 milliseconds is very common on average, and cumulative deviation remains quite competitive, especially in the value-based IPS market. Not fast TN, but generally good for motion clarity.
Unfortunately, budget-based VA boards aren't used as much as the best boards in Samsung's Odyssey G7 and G9 series today. It's very common to use a 9ms to 13ms response time here, which puts the best budget VA panels in the average IPS budget. You'll also see surface spots, which are seen as a dark path following moving objects, which you don't get with the other two LCD technologies.
However, most of the focus these days is on TN-based esports monitors when it comes to backlight exposure, so monitors like the BenQ XL2546K can get some great deals on the best IPS or VA monitors. in this feature. We've also seen great performance with IPS and VA displays, but the TN is the better app.Summary
Summarizing each of the three major LCD technologies is more difficult today than in previous years, as there has been a great deal of focus on improving IPS and VA panels. This resulted in better gaming screens for everyone and more screens to analyze and keep us occupied, which is always a good thing.
< if We have to summarize today's LCD ecosystem, TN panels are a dying race and their major strengths have been addressed in recent years. TN boards are still very fast and great for competitive gaming, but they are no longer fast-paced, especially at high levels. The main advantage of buying TNs is their cost-effectiveness and speed compatibility even with entry level panels, but these disadvantages such as viewing angle, contrast ratio, and coverage range, make them unsuitable for many situations and may not be what you want. I want to pick these days
VA panels are a real mixing bag. At the highest level, VAs are very competitive with excellent motion performance, no spots on dark surfaces, good contrast ratios and good colors. To some extent, they have to replace IPS as an intermediate technology that offers a little bit of everything. In any case, the response to Payin Bazaar, VA, was attributed to the caravan of Khobi Ra, who preserved my Canada, but there is evidence of the benefit of the panel, which is a high line of blood, and the movement of a car is a problem that has a problem with me and the end of it.
