TFT

TFT o Thin Film Transistor (Transistor de Película Fina) is a special type of field effect transistor which is fabricated by depositing thin films as well as an active semiconductor layer of dielectric material and metal contacts on a base of support. A common substrate is glass. One of the first applications of TFTs are liquid crystal displays.

 

 

 

 

 

 

 

 

 

 

 

The TFTs can be manufactured with a variety of semiconductor materials. The most common is silicon. The characteristics of silicon-based TFT depends on its crystalline state. That is, the semiconductor layer can be amorphous silicon, microcrystalline silicon or may have been tempered in a polysilicon. Other materials that can be used as semiconductors in TFTs are cadmium selenide (CdSe) and metal oxides such as zinc oxide. The TFTs can also be manufactured using organic materials (Organic TFT or OTFT).

 

Using semiconductors and transparent electrodes, such as Indium-Tin Oxide (ITO), TFT devices can be completely transparent.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

TFT-LCD

TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is a variation of liquid crystal display (LCD) that uses technology (TFT) thin film transistor to improve its image quality. TFT LCDs are one type of active matrix LCD, though this is usually synonymous with LCD. Are used in televisions, flat panel displays and projectors. In computing, TFT monitors are displacing competing CRT technology quickly, and are commonly available in sizes from 12 to 30 inches. Since 2006, have made inroads on the television market as well.
