Abstract

A plurality of thin film transistors (TFTs) and a plurality of photo detectors (PDs) are disposed inside a display component. The plurality of PDs convert detected light into electrical signals. The plurality of PDs and the plurality of TFTs are disposed on two opposite inner side surfaces of a same layer of the display component. Projections of the plurality of PDs and the plurality of TFTs on a first plane are alternately distributed, and the first plane is a plane on which the layer at which the plurality of PDs and the plurality of TFT layers are disposed is located. Fingerprint recognition accuracy can be improved by configuring a display screen including the display component provided in the embodiments of this application. In addition, PDs of different quantities are flexibly arranged, to ensure that a large region of the display screen can be used for fingerprint recognition.
