What is a Thin-Film Transistor?

TFT is special kind of Field Effect Transistor, which are faster than conventional transistor. They are mainly used in Liquid Crystal Display (LCD). TFT based LCDs have a transistor for every pixel which makes the electrical current which shows display to turned on and off faster. As each TFT is small so the charge needed is also small. This makes the display faster and smoother.
