Looking through photo-art models of home computers that are vying with each offering renowned international manufacturers, we can not help marveling at the diversity of shapes, colors and designs. Sometimes not even believe that the next semi-fantastic gimmick – just a regular computer. But in one of the founders solidarity ”face” of the PC of tomorrow should be a liquid crystal display. We are also able to join a brighter future: today in Kiev available more than a dozen models of desktop LCD-monitors.
Liquid Crystal Display (Liquid Crystal Display, LCD) – invention is not such a fad, as it may seem at first glance. Black-and-white segment indicators displaying numbers and some letters are set in electronic watches for so many years. They were followed by color – first, the size of a matchbook, then more, and finally the LCD-monitors equaled the size of their predecessors, using the cathode-ray tube.
First of all LCDs have been used in laptop computers. This is not surprising: imagine a laptop as a normal 14-inch monitor (the size of the visible area – the equivalent of 13,1 “LCD), which fastened the keyboard, stuffed full complement of the contents of the system unit. Far you can carry a” portable “device? That’s right … It is the latter circumstance, and one user to forgive the old LCD displays their shortcomings – the inertia of the image, color distortion, low resolution and astounding value.
LCD-monitors have been several stages of development, resulting in their technical specifications are gradually improving. Do not dwell on those types of displays used in notebook computers. Today, we are interested in TFT-panels – currently the most advanced of the LCD. Those who can not wait to find out what they such an awesome, we recommend an immediate appeal to the box on the next page, and satisfy their curiosity. This type of LCD screens used in desktop LCD-monitors.
Why do liquid crystal displays with one voice tip a bright future? Why the West, they have caused such a stir that the manufacturers of LCD panels cannot cope with growing demand and sometimes even forced to raise prices on their products? And why are we just now started talking about them, not about things more “real” in terms of accessibility for the Ukrainian user (for LCD-monitor – “toy” is not cheap)? First, they are really in many respects superior to conventional. Secondly (and here are powerless rigorous calculations and arguments), desktop LCD display – it’s cool. Such a thing instantly dispel all doubts of others in your success.
Three reasons for deciding to buy LCD-monitor right now
1. High-definition images. Each pixel on the screen of LCD-panel displays in a separate cell of a liquid crystal matrix, structurally separated from its neighbors. Such a design allows to give it shape. In ordinary displays, pixel is formed of several groups of dots or strips of three primary colors. Its boundaries are always more or less blurred. As a result, the sharpness of “pictures” on the LCD screen is higher than the on-screen picture tube, which is especially noticeable when working with contrasting objects – for example, black letters on white background. For this and other reasons, LCD-monitors offer better picture and is not harmful to vision, as usual.
2. The absence of harmful radiation. Display with a cathode-ray tube to generate the image creates a beam of charged particles from the bottom of the device to the screen, and hence the user. This radiation can then cause various diseases. Restrictions on the flow rate of particles and coatings can reduce the risk but not eliminate it. As for the LCD-panels, in which directional radiation is absent – to create an image it is not necessary. We may assume that such displays are harmless to humans. Therefore, advocates of healthy lifestyles throughout the world prefer to use LCD displays.
3. Compactness and larger viewable area. To use the CRT requires the electron gun was at some distance from the screen surface. Thus, to reduce the overall dimensions of the monitor is very difficult. LCD display in this respect is much more convenient – LCD-panel thickness does not exceed 2 – 3 cm means that even at a small desk after setting the monitor will have a lot of space.
In addition, the entire surface of the LCD is working, while at the edges of the picture tube there are unused areas. Because of this, the image size to 15-inch LCD screen is almost the same as on a CRT with a diagonal of 17 “.
