Abstract

The photoresponse characteristics of metal-oxide (MeO) semiconductor photosensors have been studied. Compared to the amorphous-Si-based photo-TFT, the MeO photo-TFT demonstrates superior EQE and responsivity. However, due to its inherent slow recovery to the dark state after the illumination is stopped, a unique sensing scheme suitable for the high-speed array operation is used, yet maintaining a simple array architecture as a solution for large-area interactive displays.
