New Amorphous In–Ga–Zn–O Thin-Film Transistor-Based Optical Pixel Sensor for Optical Input Signal With Short Wavelength

摘要

This paper presents an optical sensor based on amorphous In–Ga–Zn–O (a-IGZO) photo thin-film transistors (TFTs). To maintain a high signal-to-noise ratio (SNR) of the optical sensor against a variety of ambient white light, this paper employed a-IGZO phot
