Abstract: A thin film transistor optical detecting sensor includes an array substrate having a transparent substrate, a plurality of sensor thin film transistors disposed on the transparent substrate, each having a first silicon layer of a first thickness, a plurality of storage capacitors, each connected with a corresponding one of the plurality of sensor thin film transistors, storing charges of an optical current, and a plurality of switch thin film transistors, each having a second silicon layer of a second thickness less than the first thickness.
