Title:
PATTERN RECOGNITION SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/000963
Kind Code:
A1
Abstract:
A pattern recognition substrate and a display device, comprising: a base substrate (101); a photosensitive device (102) which is arranged on the base substrate (101) and comprises a first electrode (1021), a photoelectric conversion layer (1022) and a second electrode (1023) that are stacked, where the photoelectric conversion layer (1022) comprises an I-type semiconductor layer, the thickness of the I-type semiconductor layer is enough to convert a part of fingerprint-reflected light to an electrical signal, the first electrode comprises a light-transmitting region, and the light-transmitting region transmits the fingerprint-reflected light which is converted by the photoelectric conversion layer (1022); and a light absorbing layer (103) which is arranged between the base substrate (101) and a layer where the photosensitive device (102) is located and absorbs the fingerprint-reflected light not converted by the photoelectric conversion layer (1022).
