What kinds of monitors exist?

The monitor is the most important component of any computer system. It is the device through which the computer communicates the result of its work to the person. If the user inputs the original data with the mouse and keyboard, then the computer reports the result of its calculations through the image on the monitor screen .
Such a kind of dialogue. Unlike small internal components, this device is impossible not to notice, so everyone has a general idea of it. By this article we will supplement the luggage of knowledge, considering in more detail the types of monitors.

Depending on the type of screen used, all such display devices can be divided into two large groups - modern liquid crystal (LCD, TFT, LCD) and virtually removed from mass production, electron beam (CRT). Sometimes the list is supplemented with the third kind - plasma panels, but these are quite specific solutions, which can not be called mass. Thus, studying types of monitors, are limited to LCD and CRT.

For sure, many still remember how TVs looked before the "liquid-crystal era". They were quite massive devices, the screen of which was far from perfectly flat. Although in recent years the situation in this regard has changed markedly. Who had the opportunity to look inside the CRT casing of the TV, they know that almost all of its volume was occupied by a cathode-ray tube, and the size of the control board rarely exceeded the area of the album sheet. The connection between the monitor and the TV is direct: they use the same principle of operation. Of course, within the same production technology.

Considering the types of monitors, you can not leave out the features of a particular solution. Thus, let's list the advantages of CRT monitors :

- Almost ideal transmission of all color gamut, even the most budgetary model in this respect is much faster than the expensive LCD monitor;

- Absence of viewing angles - the picture on the screen is always visible, regardless of how exactly the beam of vision falls on it;

- the broken pixels, the scourge of the whole liquid crystal technology, can not exist in CRT models;

- there is no problem with blurring the image while displaying dynamic scenes.

But liquid crystal types of monitors can boast of completely different characteristics:

- Low power consumption from the network, the usual value is 40 W (compare with 80 and more CRT);

- compact dimensions and low weight, which means that to place such a device on the wall, there is no need to mount a bulky suspension structure;

- Significantly less load on the eyesight: the minimum frequency of the flicker of the backlight system is hundreds of megahertz (contrary to the stereotype that has formed, due to the presence of PWM regulation, it still exists);

- an ideal clarity of the image and no problems with converging the rays at one point, as well as the impossibility of distorting the geometry.

In liquid crystal monitors there are a number of characteristics that are not available in CRTs. This is due to too much difference in technology. Thus, the following types of monitor matrices are distinguished: the most common TNs, promising IPS, various VA modifications. Each of them has only its inherent features, which are important to consider when buying an LCD monitor.
