Patent ID: 11417140

Abstract:
A display panel and a display device are provided. The display panel includes a display area, at least a part of which is reused as a fingerprint recognition area, and a plurality of fingerprint recognition pixels located in the fingerprint recognition area. The display area includes light-emitting sub-pixels, a substrate, a driving circuit layer, and a pixel definition layer having openings for defining light exiting areas of the light-emitting sub-pixel. The fingerprint recognition pixel includes an ultrasonic fingerprint sensor and a reading control circuit located in the driving circuit layer, and the ultrasonic fingerprint sensor includes a first electrode, an ultrasonic material layer, and a second electrode, which are arranged sequentially from the substrate to the driving circuit layer. The first electrode is electrically connected to the reading control circuit, and the ultrasonic material layer is on a side of the pixel definition layer facing away from the substrate.
