Abstract

The invention provides a display panel and a display device. The display panel comprises a display area. The display panel comprises a substrate base plate, a drive circuit layer and a display devicelayer which are laminated. The drive circuit layer is located between the substrate base plate and the display device layer. The display panel also comprises a plurality of pixel units. The pixel units are located in the display area. The display panel also comprises semiconductor photosensitive active layers. Orthographic projections of the semiconductor photosensitive active layers in the planewherein the display panel is are located between the orthographic projections of two adjacent pixel units in the plane wherein the display panel is. The semiconductor photosensitive active layers comprise first signal input ends, second signal input ends, first signal output ends and second signal output ends. The display panel realizes fingerprint identification according to current-voltage characteristics of the semiconductor photosensitive active layers. According to the display panel and the display device provided by the invention, a screen-to-body ratio is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Since fingerprints are inherent to each person, they are unique. With the development of technology, a variety of display devices with fingerprint identification functions and electronic devices including display devices, such as mobile phones, tablet computers, and smart wearable devices, have appeared on the market. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display devices with fingerprint identification function, the fingerprint identification module is often arranged in the non-display area of ​​the display panel, and the fingerprint identific...
