THIN FILM TRANSISTOR AND PRESS SENSING DEVICE USING THE SAME

摘要

A thin film transistor and a press sensing device using the thin film transistor are disclosed. The thin film transistor, comprises a source electrode; a drain electrode spaced from the source electrode; a semiconductor layer electrically connected with the source electrode and the drain electrode, a channel defined in the semiconductor layer and located between the source electrode and the drain electrode; and a gate electrode electrically insulated from the semiconductor layer; and an insulative layer configured for insulating the source electrode, the drain electrode, and the semiconductor layer from each other, wherein the insulative layer is made of a polymeric material with an elastic modulus ranged from about 0.1 megapascal (MPa) to about 10 MPa.
