https://en.wikipedia.org/wiki/Thin-film%20transistor | A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is made by thin film deposition. TFTs are grown on a supporting (but non-conducting) substrate. A common substrate is glass, because the traditional application of TFTs is in liquid-crystal displays (LCDs). This differ... |
