OPTICAL FINGERPRINT IDENTIFICATION UNIT, DISPLAY PANEL, METHOD FOR MANUFACTURING OPTICAL FINGERPRINT IDENTIFICATION UNIT AND METHOD FOR IDENTIFYING FINGERPRINT

摘要

The present disclosure provides an optical fingerprint identification unit, a display panel, a method for manufacturing an optical fingerprint identification unit and a method for identifying a fingerprint. The optical fingerprint identification unit includes a substrate, and a light source, a photoluminescent layer and a light sensor above the substrate. The light source is configured to emit visible light. The photoluminescent layer is configured to receive the visible light reflected by a fingerprint and convert the received visible light into non-visible light. The light sensor is configured to detect the non-visible light.
