Abstract:
The present disclosure provides a display panel and a display device. The display panel includes: a plurality of light-emitting devices; a plurality of fingerprint recognition sensors; a plurality of pixel driving circuits each corresponding to one of the plurality of light-emitting devices; and a light-emitting scan driving circuit for controlling whether or not the plurality of light-emitting devices emit light. The light-emitting scan driving circuit is used to output a first pulse signal to a corresponding pixel driving circuit during a fingerprint recognition time phase, and to output a second pulse signal to a corresponding pixel driving circuit during a non-fingerprint recognition time phase. A period of the first pulse signal is different from a period of the second pulse signal.
