GUIDE TO HIGH-DEFINITION TELEVISION HDTV – LCD and Plasma
ByKnowing that as we shall see there are many parameters and characteristics that must be considered when choosing a TV, the problem of the panel is certainly the most immediate. The two technologies are going for more Plasma and LCD .
The first thing to say to make clear is that Plasma and LCD are not synonymous with high definition. There are two types of televisions that support high definition (but not always) and even television cathode ray tube instead to catch up.
Moreover, despite the efforts of producers, the view through the picture tube is still best (to equal the resolution of course) than any other flat screen. For technical questions, brilliance, brightness and sharpness of images on CRT is still unbeatable. Of course with the new panels will have a range of benefits that pay off a small sacrifice in quality.
It must immediately be said that between plasma and LCD technology, there is no “winner” but only the most adaptable to the needs of those who buy. So be considered the characteristics of both technologies to see what going to put in our living room. There are better lcd plasma televisions of the same band and vice versa, or for which a comparison is made on the road, side by side with the devices and the technical specifications in hand, or you try to go “except” starting from the information that we are with unravel.
First a brief discussion on two technologies:
LCD
The technology of the LCD monitor is perhaps the most famous and familiar of the two. Briefly, these TVs (Liquid Crystal Display) screen is composed of a thin layer of liquid trapped in tiny cells distributed on the surface of each panel and with electrical contacts. When you apply power, it creates an electric field in the cell that polarizes the liquid crystal. Effect of polarization, they turn letting the light behind. Naturally, the principle is very complex, but conceptually the vision is possible thanks to the control of the twist of the liquid crystal cells using electric fields.
PLASMA
The operation of a plasma television is based on an understanding physical / chemical properties of gases. Plasma is a gas mixture that is heavily ionized (that is bombarded with electrons) through electric shock. As a result, the plasma produces ultraviolet light. Is then channeled and distributed on the panel of TV, between two glass plates with electrodes, and suitably energized with electrical control. Depending on the accuracy of discharge control and throttle response, you will be able to compose images of light that are visible through the glass. The great advantage of this technique is the achievement of panel sizes large, very wide viewing angle and color quality high.
