Abstract

By placing a transparent conductive ITO layer atop a display driver thin-film transistor (TFT), a dual-gate photosensitive TFT is formed to integrate a fingerprint sensing function in a display pixel. An analytical model is proposed to elaborate its working principles in achieving both fingerprint imaging and display driving functions. [ABSTRACT FROM AUTHOR]
