Those days when computer screens were heavy and bulky, and the main characteristic when buying them, were price. Now the electronics market offers a large selection of monitors. They differ in size, characteristics, prices and, of course, the matrix. It is she who is one of the main elements of the screen. Despite the fact that there are also a considerable number of matrices, only a few options are the most common.
In the production of all modern screen models, two basic technologies are used, these are:
- LCD is a liquid crystal technology. It was she who replaced the cathode ray tube and ousted the latter from the market for electrical appliances.
- LED is a liquid crystal display whose matrix is illuminated with small LEDs.
The remaining existing types are more advanced varieties of these two species.
You can safely call a centenarian among all existing screens. In the manufacture of pixels are used, which are twisted in a spiral. This method made it possible to achieve a very good response time.
ATTENTION! Response time is one of the main characteristics of any screen. It is he who is responsible for how clear and smooth the transmitted image will be.
Despite the fact that TN - technology is able to provide a good response time, this option has more minuses than pluses. The disadvantages include:
- the display is very inexpensive to manufacture - this can lead to the appearance of broken pixels after the purchase;
- the filter is located horizontally here, so the color rendering and contrast are very low;
- the viewing angle also leaves much to be desired - if you turn the screen a little, the image becomes almost indistinguishable.
Suitable for use in an office where not particularly high screen specifications are required.
TN + Film Matrix
It is an advanced version of the TN display. During the production, another special layer was added, which slightly improved the viewing angle. Due to its low cost, it is very popular with both manufacturers and users.
REFERENCE! According to surveys, about 90% of users use monitors with this type of matrix.
The disadvantages of this technology include:
- despite the added layer, the level of the viewing angle is still unsatisfactory;
- the screen cannot provide good color reproduction, a vivid picture and contrast - many users complain that when working behind such a screen, their eyes quickly get tired.
The display is popular with gamers, as it has a very high response time. It is also suitable for fans to watch videos.
The abbreviation can be deciphered as a "thin film transistor." This option is not an independently existing matrix production technology. This is still the same TN - monitor, but the pixels here are controlled in a different way - using microtransistors. In other words, this is not a separate option, but a pixel management technology.
It is an upgrade of TFT technology. It has a very high quality color rendering. Here, the pixel molecules are arranged in parallel. Thanks to this, the screen has a large viewing angle. The picture is very bright, realistic and juicy. It also provides excellent black color reproduction. It is he who is responsible for contrast.
Despite these characteristics, the technology has its drawbacks. So, due to the parallel arrangement of pixels, the response time of the monitor is very low. For this reason, it is not suitable for games and watching videos. If moving objects are present in the image, they will leave loops. The price of such displays is very high.
This matrix is popular with people professionally engaged in design and photography.. Clarity of the picture, color reproduction and maximum realism are very important for professionals.
It is a cheaper option for IPS monitors. By their main characteristics, they are very close to IPS. Among non-professional monitors, they have maximum color reproduction, brightness and contrast. However, the response time is also low.
They will not be suitable for use by professionals, since the experienced eye will notice a change in semitones at any deviation from the perpendicular line of sight. The average user will not see such nuances.
VA, MVA and PVA matrices
Just like TFT, they are technologies for the production of the monitor matrix, and not a separate version of it.
- VA - vertical alignment. Do not transmit light when turned off, which is typical for TN monitors.
- MVA is an advanced version of VA technology. Response time has been improved. This was achieved thanks to the Over Drive method.
- PVA is Samsung’s patented development. In fact, this is the same MVA.
There are several ways to learn about a type. These include:
- The easiest option is to look at the necessary information in the documents. As a rule, it is indicated in the "Specifications" section.
- Another fairly simple option is to go to the manufacturer's website and find out what is required in the product catalog.
- The third option is to look at the color image from different angles. If the color is greatly distorted, then most likely it is TN. A black image that turns purple is IPS. The only monitor option whose image will not be distorted is OLED. But this is a very expensive version of the monitor and it is not widespread.
When choosing a monitor, you need to consider why it will be used:
- for professional work, IPS technology is ideal;
- gamers will like the MVA option;
- with a limited budget and for office work, you can take a TN or TN + Film monitor;
- ideal for all categories would be OLED - it has optimal and high performance, but it is very expensive.
The range of devices with different characteristics is quite wide, so choosing the right option is quite simple.
