From Wikipedia, the free encyclopedia.
A thin film transistor (TFT) is made by depositing thin films for the metallic contacts, semiconductor active layer, and dielectric layer. Their distinctive utilitarian property is transparency.
Its main application is in design of flat-panel displays, a kind of LCDs (liquid crystal displays). TFTs are the better variant of the LCD technology and more flexible one, since with them each pixel is controlled individually. This is achieved by means of to four transistors. In this kind of techology is provides today the highest resolution of LCDs. Due to its design TFTs are often called Active matrix LCDs.
