This abstract first appeared for US patent application 20250015103 titled 'PATTERN RECOGNITION SUBSTRATE AND DISPLAY DEVICE
Original Abstract Submitted
a pattern recognition substrate and a display device are disclosed, the pattern recognition substrate includes: a base substrate; a photosensitive device arranged on the base substrate and including a first electrode, a photoelectric conversion layer and a second electrode that are stacked, where the photoelectric conversion layer includes an i-type semiconductor layer with a thickness enough to convert a part of fingerprint-reflected light to an electrical signal, the first electrode includes a light-transmitting region transmitting the fingerprint-reflected light which is converted by the photoelectric conversion layer; and a light absorbing layer arranged between the base substrate and a layer where the photosensitive device is located to absorb the fingerprint-reflected light not converted by the photoelectric conversion layer.
