What is better matrix ips or va. TN vs IPS. Which monitor to choose

The popularity of each product depends on two factors. This is the quality of the product and its price. TN matrices, which dominated the market for many years, attracted with their low cost. However, with the development of IPS technology and its subsequent reduction in price, the choice of buyers was predetermined. The laurels of the "people's favorite" passed to a new applicant.

But not everything is so simple. The development of IPS has given rise to many variations of this matrix. The most famous of them is PLS. Which of the two options is better? What are the differences between the other varieties of IPS? The answers to these questions will guide the buyer to the right choice.

IPS technology

By 1996, the hegemony of TN-matrices came to an end. Hitachi and NFC have successfully completed the joint development of an innovative technology. IPS-matrices were released and presented to the masses.

The main purpose for which this product was created was to replace the outdated TN predecessor. Such familiar ailments at that time as poor color reproduction, low contrast and small viewing angles are a thing of the past. New monitors naturally came to market leadership.

"In-Plane Switching" literally translates as " on-site switching". High quality The image of this matrix is ​​achieved due to a fundamentally different arrangement of liquid crystals. If in TN they were arranged in a spiral, then in IPS they were parallel to each other.

Picture Perfect

The new solution offers immediately several advantages, with this in mind, their predecessors simply cannot compete:

There was also a small, but pleasant trifle. Reaction to physical impact is excluded. If you poke a finger at a TN monitor, then clearly visible “waves” will appear at the point of contact, distorting the image. In "In-Plane Switching" this problem is not present.

Not without flaws

However, even so innovative technology cannot be called ideal. IPS-matrices still have obvious disadvantages:

Modern matrices are also not without the above disadvantages. . However, it would be unfair to say that the technology has remained in place compared to past variations.

Further development

With the opening in 1996, the desire for a perfect picture only gained momentum. The technology needed to be cheaper and improved with a high response time. An equally important task was to improve its strengths..

The "innate" shortcomings of "In-Plane Switching" have become less critical. Especially when compared with what happened in 1996.

However, the cost of this matrix and its response time are still far from ideal. This was the starting point for the development of an alternative that has gained wide popularity in the monitor market.

With coming pls

At the end of 2010, Samsung presented to the world its vision of progress for modern matrices- „Plane-to-Line Switching“. PLS was positioned as fundamentally new replacement imperfect IPS. Representatives of Samsung did not give any descriptions of their own technology.

True, at one point the corporation indirectly recognized its matrix as a kind of IPS. This happened during litigation with LG. The lawsuit filed by Samsung claimed that AH-IPS is a modification of their PLS technology. In fact, this was not true. On the other hand, nothing cancels the series technical advantages PLS Compared to Competitor:

Image quality and RGB color gamut in PLS is in no way inferior to modern IPS. However, data from various expert studies are conflicting. Some come to the conclusion that PLS is somewhat superior to its competitor in this regard. D others believe that there is no difference here and both matrices are equal.

The conclusion follows from this: if there is still a difference in image quality / color reproduction between PLS and IPS, then it is insignificant.

Connoisseurs of bright realistic pictures and clear dynamic scenes are advised to look towards PLS. Yes, the response time of this matrix is ​​​​slightly higher than that of TN. However, the difference is not critical - the effect of "blurring" objects on the display is excluded in both versions. But the color reproduction, brightness, contrast and viewing angles here definitely outweigh in the direction of PLS. A worthy option for a wide audience who are fond of games and movies.

"In-Plane Switching" deserves the attention of those who care exclusively about color reproduction (photographers, designers, etc.). The number of modifications of this technology is much wider than the most popular ones that were considered earlier. However, professional work with graphics and color requires a purely individual approach. For various tasks, a monitor on a PLS-matrix is ​​quite suitable. Moreover, it will be much cheaper. than any specific type of IPS.

The average user will also appreciate modern varieties this matrix. Under two conditions:

1. A monitor based on it has similar characteristics with a comparable PLS-matrix counterpart in the price range.
2. This monitor with a matrix costs less than the same analogue on PLS.

Do you want a high quality image with low response time? PLS-matrix at your service. Requires monitor strictly for professional work with graphics? The same PLS and many varieties of IPS will satisfy your needs - the choice depends on meeting the required technical parameters and product cost. Have you found a monitor with a modern IPS-matrix, whose characteristics are close to a PLS analogue of a comparable price, but at the same time cheaper? Decent buy option.

Telling about IPS differences and TN matrices as part of advice when buying a monitor or laptop. It's time to talk about all modern display technologies, which we may encounter and have an idea about types of matrices in devices of our generation. Do not confuse with LED, EDGE LED, Direct LED are the types of screen backlighting and display technology are indirectly related.

Probably, everyone can remember their monitor with a cathode ray tube, which they used earlier. True, users and fans still meet CRT technology. Currently, screens have increased in diagonal, display manufacturing technologies have changed, there are more and more varieties in the characteristics of matrices, denoted by the abbreviations TN, TN-Film, IPS, Amoled, etc.

The information in this article will help you choose a monitor, smartphone, tablet and other various kinds of equipment. In addition, it will highlight the technologies for creating displays, as well as the types and features of their matrices.

A few words about liquid crystal displays

LCD (Liquid Crystal Display)- This is a display made on the basis of liquid crystals, which change their location when voltage is applied to them. If you come close to such a display and look closely at it, you will notice that it consists of small dots - pixels (liquid crystals). In turn, each pixel consists of red, blue and green subpixels. When a voltage is applied, the subpixels line up in a certain order and let light pass through them, thus forming a pixel. certain color. Many of these pixels form an image on the screen of a monitor or other device.

The first mass-produced monitors were equipped with matrices TN- having the simplest design, but which cannot be called the highest quality type of matrix. Although among this type of matrices there are very high-quality specimens. This technology is based on the fact that in the absence of voltage, the subpixels pass light through themselves, forming on the screen white dot. When voltage is applied to subpixels, they line up in a certain order, forming a pixel of a given color.

Disadvantages of TN matrix

• For the reason that the standard color of a pixel, in the absence of voltage, is white, given type matrices does not have the best color reproduction. Colors appear dimmer and faded, while blacks appear more of a dark grey.
• Another main disadvantage of TN matrix is ​​the small viewing angles. Partially, they tried to cope with this problem by improving the TN technology to TN + Film, using an additional layer applied to the screen. Viewing angles have become larger, but still remained far from ideal.

At present, TN+Film matrices have completely replaced TN.

Advantages of TN matrix

• short response time
• relatively low cost.

Drawing conclusions, it can be argued that, if necessary, inexpensive monitor For office work or surfing the Internet, monitors with TN+Film matrices work best.

The main difference between IPS matrix technology and TN- perpendicular arrangement of subpixels in the absence of voltage, which form a black dot. That is, in a state of calm, the screen remains black.

Advantages of IPS matrices

• better color reproduction compared to TN screens: you have bright and rich colors on the screen, and the black color remains really black. Accordingly, when voltage is applied, the pixels change their color. Given this feature, owners of smartphones and tablets with IPS screens can be advised to use dark color schemes and wallpaper on the desktop, then the smartphone battery will work a little longer.
• large viewing angles. In most screens they are 178°. For monitors, and especially for mobile devices(smartphones and tablets), this feature is important when a user chooses a gadget.

Disadvantages of IPS matrices

• big time screen response. This affects the display in dynamic pictures such as games and movies. In modern IPS panels, things are better with response time.
• high cost compared to TN.

Summing up, it is better to choose phones and tablets with IPS matrices, and then the user will get great aesthetic pleasure from using the device. The matrix for the monitor is not so critical, modern.

AMOLED screens

The latest smartphone models are equipped with AMOLED displays. This technology for creating matrices is based on active LEDs, which begin to glow and display color when voltage is applied to them.

let's consider features of Amoled matrix:

• Color rendering. The saturation and contrast of such screens is higher than required. Colors are displayed so vividly that some users may experience eye strain when long work with your smartphone. But the black color is displayed even more black than even in IPS-matrices.
• Display power consumption. As with IPS, displaying black requires less power than displaying a particular color, much less white. But the difference in power consumption between displaying black and white in AMOLED screens is much larger. Displaying white requires several times more power than displaying black.
• "Memory pictures". When a static image is displayed for a long time, traces may remain on the screen, and this in turn affects the quality of the display of information.

Also, due to its rather high cost, AMOLED screens are still used only in smartphones. Monitors built on this technology are unreasonably expensive.

VA (Vertical Alignment) — this technology, developed by Fujitsu, can be seen as a compromise between TN and IPS matrices. In VA matrices, the crystals in the off state are located perpendicular to the plane of the screen. Accordingly, the black color is provided as pure and deep as possible, but when the matrix is ​​rotated relative to the direction of view, the crystals will not be visible in the same way. To solve the problem, a multi-domain structure is used. Technology Multi-Domain Vertical Alignment (MVA) provides protrusions on the plates, which determine the direction of rotation of the crystals. If two subdomains are rotated in opposite directions, then when viewed from the side, one of them will be darker and the other lighter, thus for the human eye the deviations cancel each other out. PVA matrices developed by Samsung do not have protrusions, and in the off state, the crystals are strictly vertical. In order for the crystals of neighboring subdomains to rotate in opposite directions, the lower electrodes are shifted relative to the upper ones.

To reduce response time, Premium MVA and S-PVA matrices use a dynamic voltage boost system for certain sections of the matrix, which is commonly referred to as Overdrive. The color reproduction of PMVA and SPVA matrices is almost as good as that of IPS, the response time is slightly inferior to TN, viewing angles are as wide as possible, blacks are the best, brightness and contrast are the highest possible among all existing technologies. However, even with a slight deviation of the direction of view from the perpendicular, even by 5–10 degrees, distortions in semitones can be noticed. For most, this will go unnoticed, but professional photographers continue to dislike VA technologies for this.

MVA and PVA matrices have excellent contrast and viewing angles, but things are worse with the response time - it grows as the difference between the final and initial pixel states decreases. Early models of such monitors were almost unsuitable for dynamic games, and now they show results close to TN matrices. The color reproduction of *VA matrices is, of course, inferior to IPS matrices, but remains at a high level. However, due to their high contrast ratio, these monitors are an excellent choice for text and photo work, drawing graphics, and as home monitors.

In conclusion, I can say that the choice is always yours ...

TFT and IPS matrices: features, advantages and disadvantages

IN modern world we regularly come across the displays of phones, tablets, PC monitors and TVs. Technologies for the production of liquid crystal matrices do not stand still, and therefore many people have a question, what is better to choose TFT or IPS?

In order to fully answer this question, it is necessary to carefully understand the differences between both matrices, highlight their features, advantages and disadvantages. Knowing all these subtleties, you can easily choose a device whose display will fully meet your requirements. Our article will help you with this.

TFT matrices

Thin Film Transistor (TFT) is a liquid crystal display manufacturing system based on an active matrix of thin film transistors. When a voltage is applied to such a matrix, the crystals turn towards each other, which leads to the formation of a black color. A power outage gives the opposite result - the crystals form a white color. Changing the applied voltage allows you to form any color on each individual pixel.

The main advantage of TFT displays is the relatively low production cost compared to modern counterparts. In addition, such matrices have excellent brightness and response time. Due to this, distortions when viewing dynamic scenes are invisible. Displays made using TFT technology are most often used in budget TVs and monitors.

Disadvantages of TFT displays:

• • low color rendering. The technology has a limit of 6 bits per channel;
  • the spiral arrangement of the crystals adversely affects the image contrast;
  • image quality is noticeably reduced when the viewing angle is changed;
  • high probability of the appearance of "broken" pixels;
  • relatively low power consumption.

The shortcomings of TFT matrices are most noticeable when working with black. It can be distorted to gray, or vice versa, be too contrasty.

IPS matrices

The IPS matrix is ​​an improved continuation of displays developed using TFT technology. The main difference between these matrices is that in TFT liquid crystals are arranged in a spiral, while in IPS the crystals lie in the same plane parallel to each other. In addition, in the absence of electricity, they do not rotate, which has a positive effect on the display of black.

Advantages of IPS matrices:

• viewing angles at which image quality does not decrease are increased to 178 degrees;
• improved color rendering. The amount of data transmitted per channel has been increased to 8 bits;
• significantly improved contrast;
• reduced energy consumption;
• low probability of the appearance of "broken" or burnt out pixels.

The image on the IPS matrix looks more lively and saturated, but this does not mean that this technology is without flaws. Compared to its predecessor, IPS has significantly reduced image brightness. Also, due to the change in the control electrodes, such an indicator as the response time of the matrix has suffered. The last but not least disadvantage is the relatively high price of devices that use IPS displays. As a rule, they are 10-20% more expensive than similar ones with a TFT matrix.

What to choose: TFT or IPS?

It should be understood that TFT and IPS matrices, despite significant differences in image quality, are very similar technologies. They are both created on the basis of active matrices and use liquid crystals of the same structure. Many modern manufacturers give their preference to IPS matrices. Largely due to the fact that they can compete more worthily with plasma matrices and have significant prospects in the future. However, TFT matrices are also evolving. Now on the market you can find TFT-TN and TFT-HD displays. They are practically not inferior in image quality to IPS matrices, but at the same time they have a more affordable cost. But on this moment there are not many devices with such monitors.

If image quality is important to you and you are willing to pay a little extra, then a device with an IPS display is the best choice.

For a number of reasons, liquid crystal screens are in great demand among users and are the most in demand in the domestic market. Modern LCD displays are divided into two types of matrices - IPS and TN. In this regard, many buyers have a question, what is better IPS or TN screen?

In order to understand which technology is better, you should consider all the advantages and disadvantages of IPS and TN screens. However, it is worth noting that both technologies have come a long way of development and improvement, which made it possible to create screens of decent quality. Taking into account some technological features of technologies, one or another screen should be chosen depending on the situation.

When choosing a screen, there are a few things to consider. important parameters:

• Screen resolution;
• Color rendition;
• Color saturation, contrast and brightness of the image;
• Response time;
• Energy consumption;
• Durability.

1.TN vs IPS

First of all, you should pay attention to the screen resolution. This is one of the most important parameters that directly affects the image quality, as well as the diagonal size. To put it simply, resolution is the number of pixels on the screen, both vertically and horizontally. For example, a resolution of 1920x1080 indicates that the screen has 1920 pixels horizontally and 1080 pixels vertically. Accordingly, the higher the resolution, the higher the density of points, and the more sharp image you can get.

It should be understood that modern technology allows you to enjoy high resolution video and photo images. Therefore, it is worth giving preference to screens with a maximum resolution. To date, the highest resolution is 1920x1080 pixels (Full HD). Of course, such monitors or TVs will have a higher cost, but you will be able to fully experience all the benefits of technology.

If we talk about which matrix is ​​better than TN or IPS in terms of resolution, then both technologies are equal here. They can be either low or high resolution, it all depends on the cost of the device.

2. Color reproduction

Color reproduction is a parameter that determines the amount of colors and shades displayed by the screen. The saturation of colors depends on this, as well as the realism of the picture. Modern technologies made it possible to make screens with a sufficiently high level of color reproduction, regardless of technology. However, there are some differences between IPS and TN screens.

2.1. Color rendering IPS matrix

The features of this technology made it possible to make a screen with the most realistic colors. It is worth noting that IPS displays are most in demand among professional photo editors, as well as among those involved in image processing. This is because IPS monitors have the highest color depth (black and white) as well as the most a large number of of displayed colors and shades - about 1.07 billion. This makes the image as realistic as possible.

Besides, IPS screens have the highest brightness and contrast, which also positively affects the image quality.

2.2. Color reproduction of TN matrices

This type of matrix, although it has high level image quality, as well as excellent color reproduction, is still significantly inferior to IPS screens. In addition, such matrices have smaller viewing angles.

If it says that TN Film or IPS is better in terms of color reproduction, then the answer is unequivocal - IPS matrices are significantly superior to TN + Film screens. Although, at home, any monitor will allow you to enjoy excellent quality and color depth.

3. Response time

This parameter determines the time during which a liquid crystal molecule is able to change its position for display from black to white and vice versa. This is especially important for those who love bright and fast special effects and colorful games. In the case of a slow response, you will be able to observe an effect called “loop” on the screen. In other words, some shadow will be visible behind fast moving objects. IN certain cases this can cause discomfort. Measures the response in milliseconds.

3.1. IPS screen response

As mentioned above, IPS screens are famous for their excellent image, picture clarity and accuracy, as well as realistic color reproduction, however, due to some technology features, such displays lose in response to TN matrices. Of course, this difference is insignificant and almost imperceptible at home, but nevertheless it is, and for some it is very important.

It is worth noting that the most modern IPS matrices have a fairly fast response, but they are more expensive than TN + Film screens.

3.2. TN matrix response

This type of matrix has the fastest response, which makes such monitors the most suitable for fans of games and 3D movies with vivid special effects.

If we talk about which IPS or TN matrix is ​​​​better in response, then TN has an advantage. However, it is worth noting that at home, all these advantages are negligible. The choice depends solely on personal preference.

4. So, what is better IPS or TN matrix

Choosing between these two technologies should take into account personal requirements, as well as for what purpose the monitor is being bought. Of course, there is an opinion that IPS matrices are more new technology, respectively, and better. However, in some situations a TN+Film matrix is ​​a better choice.

If we talk about which IPS or TN matrix is ​​better for games, then preference should be given to TN + Film. TN monitors are cheaper and also have excellent response. Although, if you are not limited by the budget, then a monitor with a matrix AH-IPS will be your ideal choice, as such a monitor combines all the advantages of IPS and TN technologies.

It is worth noting that IPS matrices are slowly but surely replacing TN + Film screens. This is reflected in the fact that every year more and more manufacturers prefer IPS screens. Of the advantages of IPS screens, large viewing angles can also be distinguished. Thanks to everyone advantages of IPS screens compete with plasma panels.

5. Comparison of two LG monitors with TN + FILM and IPS matrices: Video

Modern scientific and technological progress does not stand still and engineers of manufacturing companies are constantly developing new and new technologies or improving old ones. Initially, matrices did not exist in principle, and the production of televisions (later monitors) was reduced to lamp technology. But progress cannot be undone. . .

In monitors, manufacturers install matrices made using various technologies, they use the following types matrices TN, IPS, VA with various modifications. In the figure below you can see how the picture changes on various screens when viewing the image at an angle. TN matrices

TN+film- the first TFT panels are produced now as inexpensive screens, the advantage of low cost production. The disadvantage is small viewing angles, a decrease in brightness and contrast when viewed from the side. At first there were TN matrices, then a special film was added to improve color rendering, a kind of filter, and the matrices began to be called TN + film.

Matrices made using IPS technology

IPS Generations Summary (Hitachi)
PLS - Plane to Line Switching (Samsung)
AD-PLS - Advanced PLS (Samsung)
S-IPS- Super IPS(NEC, LG Display)
E-IPS, AS-IPS - Enhanced and Advanced Super IPS (Hitachi)
H-IPS - Horizontal IPS (LG.Display) e-IPS (LG.Display)
UH-IPS and H2-IPS (LG.Display) S-IPS II (LG.Display)
p-IPS - Performance IPS (NEC)
AH-IPS - Advanced High Performance

IPS (LG.Display)- Advanced Hyper-Viewing Angle (AU Optronics) IPS is one of the first production technologies TFT screens, was invented in 1996 (Hitachi) as an alternative to TN displays, has wide viewing angles, deeper blacks, good color reproduction, the disadvantage of a long response time, which made them unsuitable for games.

pls- (Plane-to-Line Switching) samsung translated the name of the panel as "switching-from-plane-to-line" turned out to be complete abracadabra, the literal translation "by plane to the switching line" also does not make any sense. Most likely, under this slogan, they wanted to show that the monitor has a high response time and can switch the picture at the speed of the aircraft. PLS is essentially an IPS matrix only manufactured by another company that came up with its own designation and its own production technology. The pluses include:

Response time is 4 miles second
- (GTG). GTG is the time required to change the brightness of a pixel from minimum brightness to maximum.
- wide angles review without losing the brightness of the picture.
- Increased display brightness

AD-PLS- the same panel PLS, but as samsung claims, the production technology has been slightly changed, as many experts say, this is just PR.

S-IPS- advanced IPS technology in this direction is being developed by NEC A-SFT, A-AFT, SA-SFT, SA-AFT, as well as LG.Display (S-IPS, e-IPS, H-IPS, p-IPS). Advances in technology have made it possible to achieve response times as short as 5 miles, making these displays suitable for gaming.

S-IPS II- the next generation of S - IPS panels, reducing energy consumption.

E-IPS, AS-IPS- Enhanced and Advanced Super IPS, developed by (Hitachi) one of the improvements in IPS technology, increasing brightness and reducing response time

H-IPS- Horizontal IPS, (LG.Display) in this type of matrix, pixels are placed horizontally. improved color reproduction and contrast. More than half of modern IPS panels have a horizontal pixel arrangement.

e-IPS- (LG.Display) The next improvement in matrix production is cheaper to manufacture but has the disadvantage of slightly smaller viewing angles.

UH-IPS and H2-IPS- the second generation of H-IPS technology improved matrix, increased panel brightness.

p-IPS- Performance IPS is the same as H-IPS is the marketing name of the matrix from NEC.

AH-IPS- modification of the matrix for high resolution displays (UHD), analogue of H-IPS.

AHVA- Advanced Hyper-Viewing Angle is the designation of the displays of the company (AU Optronics), the company is formed from the merger of Acer Display Technology and the screen division of BenQ Corporation.

PVA Matrix - Patterned Vertical Alignment

S-PVA - Super PVA
cPVA
A-PVA - Advanced PVA

SVA PVA matrices were developed by Samsung have good contrast, but have a number of disadvantages, the main loss of image contrast when viewed at an angle. In order to periodically update the production line, after a certain period of time, new model screen, so the following types of VA screens exist.

S-PVA- Super PVA improved matrix due to changes in production technology.

cPVA- simplified production technology screen quality is worse than S - PVA

A-PVA- Advanced PVA small absolutely not significant changes.

SVA- another modification.

VA-Vertical Alignment

MVA- Multi-Domain Vertical Alignment (Fujitsu)

P-MVA - Premium MVA
S-MVA - Super MVA
AMVA - Advanced MVA

The TFT display technology (VA) was developed by Fujitsu in 1996 as an alternative to TN matrices, screens made using this technology had the disadvantages of a long response time and small viewing angles, but had significantly best performance chromaticity. To overcome the shortcomings, production technology has improved.

MVA- next version technology in 1998, the difference was that the pixel consisted of several parts, this made it possible to achieve a better image.

P-MVA, S-MVA- Improved color rendering and contrast.

AMVA- next generation production, faster response time, better color reproduction.
