How does the thin film transistor work?

Answer 1

A thin-film transistor (TFT) is a type of field-effect transistor made by depositing thin layers of semiconductor material, typically silicon, onto a substrate. It operates by applying a voltage to the gate terminal, which creates an electric field that modulates the conductivity of the semiconductor channel between the source and drain terminals. This allows for the control of current flow, enabling the transistor to act as a switch or amplifier. TFTs are widely used in display technologies, particularly in liquid crystal displays (LCDs), due to their ability to control individual pixels effectively.
