Modern computers are not at all like those bulky slow machines, which, however, have made a whole revolution in technology. And monitors are now far gone from cathode ray tubes and kinescopes. The main difference between all monitors is the type of matrix. Of the modern, the most common can be called monitors based on liquid crystal technology. In English, this will sound like "Liquid crystal display" (liquid crystal display). You can often see another abbreviation - LCD.
Also uses TFT matrix type. This is a type of field effect transistor that is used in virtually all liquid crystal display technologies. In English, it sounds like "thin-film transistor" (usually shortened to the abbreviation TFT) Thus, we can say that most LCD monitors are also TFT monitors.
But even here there are variations. The matrix type determines both the image and the performance. Therefore, it is worth dwelling in more detail on the most popular types.
The oldest technology can be consideredTwisted Nematic (or just TN). To date, it is rightfully considered both the cheapest and the most common. Considering its simplicity, this type of matrix is constantly developing, improving, becoming better and more affordable. A new round in the development of Twisted Nematic technology 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 you to view dynamic movies on these monitors (it is not difficult to guess that this is why this type of tn matrix is \u200b\u200bcalled "Film".)
However, TN has some drawbacks. For example, it has poor color reproduction and a relatively high probability that defective subpixels will appear on the screen. Therefore, these monitors are often used in offices or 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: to get rid of the main shortcomings of TN-TFT. With the help of their IPS, the developers were able to increase the viewing angle, solve the problem with color reproduction and contrast. However, they could not avoid the negative aspects: the response time increased. The price for such monitors is naturally much higher than for TN TFT.
Another pioneering technology is IPS-S. The letter S here should mean the word"super". These types of matrices were supposed to solve the problem with viewing angles and increase the response time of the pixels. Which, in fact, the developers completely succeeded. These types of monitors are often used for gaming, advertising and graphic design screens, project demonstrations.
There are several other subtypes of IPS technology. These are Horizontal, Ultra Horizontal and Professional. They are modified versions of IPS panels and have some advantages, but also a higher price. For example, the benefits of such subtypes include increased contrast, improved display viewing angles, high-level color rendering.
