Driver-Integrated Active-Matrix Amorphous Silicon Schottky Photosensor Arrays for Display Integration

Student

Description:

This paper shows an active-matrix Schottky photodiode-based image sensor. It is shown that amorphous silicon Schottky photodiodes may be favorable over pin photodiodes due to their simpler and highly TFT-compatible manufacturing process, eliminating the need for a p-doping and retaining strong device performance. The device performance is shown and evaluated with regards to different applications such as ambient light sensing as well as in-screen fingerprint detection. An active-matrix sensor array is shown, featuring integrated row drivers and column multiplexing to reduce external driver circuitry such as ADC channels and to provide a scalable technology.
