A is a special type of field-effect transistor (FET) made by depositing thin films of active semiconductor layers, dielectric sheets, and metallic contacts over a non-conducting substrate. Unlike conventional MOSFETs, where the semiconductor itself is typically the substrate (like a silicon wafer), TFTs are built on top of substrates like glass or even flexible plastic. The Core Structure A standard TFT consists of three primary components: Three Electrodes : The Gate , Source , and Drain . TFTs operate as electronic switches
