TFT LCD Displays: The New Flat Screen
TFT LCD displays deliver crisp and colorful view of motion imagery by using thin film transistors or TFT to turn the thousands of pixels in the LCD on or off. When a pixel is off, it remains dark but when it is turned on, the pixel is lighted.
The thin film transistors in TFT LCD displays are actually miniature switches that are designed to allow individual pixels in the liquid crystal active matrix display to be turned either off or on. Therefore, a thin film transistor can deliver either a lit pixel or a dark one depending on the pixel parameters of the digital color image being displayed by the screen. The TFT LCD display active-matrix is the one responsible for making the rapid and smooth changes of shapes and colors possible. Since each pixel within the liquid crystal display is controlled actively, the colors and screen resolution are well-defined while they blend accurately. TFT LCD displays are often called flat panel TVs. They are rapidly replacing the old style cathode ray tube displays as the displays of choice. Nowadays, almost all LCD displays take advantage of the thin film transistor technology.
Newer models and versions of TFT LCD displays have all the functions of a digital set-up box. Some of these television screens have a DVD player included in their slim and sleek frames, eliminating the need to go through all the trouble of buying an extra piece of furniture or an additional multimedia player. Some of the latest and most sophisticated models of TFT LCD displays can be tilted and turned with the help of electric or hydraulic power.
