The world of today, beating dozens of TV technology, the other to fight the trumpet. But it flows to the user, because it decides the fate of all things new on the market. TV-panel TV can be divided into two types, namely direct-view TV and Flat. Also known as CRT televisions, direct view televisions have been replaced by flat-screen TVs in most homes. Bulky and can release heat over repeated use, have a lot of CRT TVDisadvantages. The next category most attractive flat-screen TV. These are classified into two types, namely, plasma and LCD TV.
LCD stands for Liquid Crystal Display. There is a thin flat screen for display of electronic information, such as text, using moving images, etc. And 'one of the fastest growing technologies of video-display in the market today. Sales of liquid crystal devices took tube set some years ago. An LCD panel is composed of pixelstransparently between the two electrodes and two polarizing filters down. When light is passed between them, the filters get excited and crystal clear images can be displayed. The electrodes are made of indium tin oxide (ITO) has been prepared. At the request of an electric field the liquid crystal molecules are oriented in alignment of the electrodes. Their surface orientation perpendicular to each other and the molecules are arranged in a spiral-shaped structure. This method, which is used in LCD glassis polarizing. This improves response times, higher resolution and better contrast and brightness. LCD panels using four techniques, namely SSFLC (surface stabilized ferroelectric liquid crystal), FLC (ferroelectric liquid crystal display), DSTN (Dual Scan Twisted Nematics) and STN (Super Twisted Nematics).
The other type of flat-screen TV and plasma TV. This is a flat screen with a screen size of 32 inches begins. It is composed of small cells instead of twoGlass plates. The glass is a mixture of noble gases. When electric current is passed, the gas is turned into plasma cells, excited phosphors to emit light. Much thinner than CRT, the image quality varies depending on the type of video-scale. In its first days, plasma televisions more definition with a resolution of 840 x 180 pixels native. But the high-definition televisions, plasma 42 inches today usually have a resolution of 1024 x 768 pixels.
Both technologies mentioned above(LCD and plasma) have their share of advantages and disadvantages. The screen size of plasma TV 32 "LCD TV while the smallest 10" are available. Plasma TVs can tend to suffer from "burn-in of static images, while LCDs are free of them. Plasma TVs are not good at high altitudes and are heavy and bulky as compared to the LCD TV. However, plasma TVs better manage the movement of LCD TVs and LCD-shine when it comes to color saturation and detail. In fact, it isNot an easy task to choose between the two. But, as a user, you should always go for the atmosphere and needs of your ad is the best.
