Modern computers are not at all like those cumbersome slow machines, which, however, have made a revolution in technology. And the monitors are now far away from the electron-beam tubes and kinescopes. The main difference of all monitors is the type of matrix. Of the modern most common are monitors based on liquid crystal technology. In English it will sound like "Liquid crystal display" (liquid crystal display). Often you can see another reduction - LCD.
The type of matrix on thin-film transistors is also used. This is a kind of field-effect transistor, which is used in virtually all technologies of liquid-crystal displays. In English, it sounds like a "thin-film transistor" (usually shortened to the abbreviation TFT) Thus, it can be said that most LCD monitors are also TFT-monitors.
But even here there are different varieties. The type of matrix determines both the image and the performance. Therefore, it is worth more detail on the most popular types.
The oldest technology can be considered Twisted Nematic (or just TN). To date, it is rightfully considered as the cheapest, and the most common. Given its simplicity, this type of matrix is constantly evolving, improving, becoming more quality and affordable. A new twist in the development of technology Twisted Nematic is an additional layer that increases the viewing angle of the monitor. This feature is called "Film". The main advantage of this innovation can be called a low price, which became the basis of its popularity, as well as a rather low response time, which allows viewing dynamic movies on these monitors (it is not difficult to guess that this is why this type of matrix tn is called "Film".)
However, TN has some drawbacks. For example, it has poor color rendition and a relatively high probability that defective sub-pixels appear on the screen. Therefore, such monitors are often used in offices or in home use with a limited budget.
Another popular technology is IPS, which was jointly developed by Hitachi and NEC. The main task of the development was this: get rid of the main disadvantages of TN-TFT. With the help of its IPS, developers were able to increase the viewing angle, solve the problem with color reproduction and contrast. However, we could not avoid the negative sides: the response time increased. The price for such monitors, naturally, is much higher than on TN TFT.
Another innovative technology is IPS-S. The letter S here should mean the word "super". These types of matrices should solve the problem with the viewing angles and increase the response time of the pixels. What, in fact, the developers have completely succeeded. Such types of monitors are often used for games, as screens for advertising and graphic design, demonstration of projects.
There are several more subtypes of IPS technology. This is Horizontal, Ultra Horizontal and Professional. They are modified versions of IPS matrices and have some advantages, but at the same time a higher price. For example, the advantages of such subtypes include increased contrast, improved viewing angles, high color rendering.
