Monitor - an essential component of any computer system.It is a device by which the computer tells a person the result of his work.If using a mouse and keyboard user makes the original data, then through the screen of a computer monitor reported the outcome of their calculations.
Such is the kind of dialogue.In contrast to the small internal components, this device can not be ignored, so the general idea of it is at everyone.With this article we supplement the knowledge base, a closer look at types of monitors.
Depending on the species used by the screen display of all such devices can be divided into two major groups - the modern liquid-crystal (LCD, TFT, LCD) and virtually removed from mass production, cathode ray (CRT, CRT).Sometimes a list of complementary third kind - plasma panels, but it's pretty specific solutions, which can not be called mass.Thus, studying the types of monitors, limited to LCD and CRT.
Certainly, many still remember, looked like TV before "LCD era."It was a fairly massive device, the screen that was far from perfect smooth.Although in recent years, the situation has changed significantly.Who has had the opportunity to look inside the body CRT TV, know that almost the entire volume occupied by a cathode ray tube, and the size of the control board rarely exceeded landscape area of the sheet.The connection between the monitor and the TV itself: they use the same operating principle.Of course, within the same production technology.
Considering the types of monitors, can not ignore the characteristics of a decision.So, we list the advantages of CRT:
- almost ideal transfer of all colors, even the budget model in this respect is far ahead of the expensive LCD monitor;
- no angles - the picture on the screen is always visible, no matter how it falls on the line of sight;
- dead pixels, the scourge of the entire liquid crystal technology, CRT models can not be;
- no problems with image blur during fast action display.
But LCD monitors boast views of very different characteristics:
- a low level of consumption from the mains power, the usual value is 40 watts (compared with 80 or more CRT);
- compact dimensions and low weight, and consequently to place such a device on a wall, there is no need to install bulky suspension structure;
- considerably less eye strain: The minimum frequency of the flicker of illumination in the hundreds of megahertz (contrary to form a stereotype, because of the PWM control, it is still there);
- great image clarity and the absence of problems with the convergence at one point, as well as the inability to geometry distortion.
On LCD monitors have a number of features that are absent in the CRT.This is due to too great differences in technology.For example, the following types of matrices monitors: The most common TN, advanced IPS, various modifications of the VA.Each of them has only her inherent features that are important to consider when purchasing an LCD monitor.
