AI Technical Summary

Technical Problem

The existing OLED display panels have poor performance, mainly because the touch electrode blocks the photosensitive opening, which causes the photosensitive device to be unable to receive enough light, affecting the accuracy of fingerprint recognition and distance detection.

Method used

The touch trace is provided on the positive projection of the substrate so that it surrounds the photosensitive opening without closing, thereby not completely blocking the light, increasing the viewing angle of the photosensitive opening, so that the photosensitive device can receive more ambient light.

Benefits of technology

By increasing the viewing angle of the photosensitive opening, the detection accuracy and sensitivity of the photosensitive device are improved, and the performance and user experience of the display panel are improved.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a display substrate and a touch layer which are arranged in a stacked mode. The display substrate comprises a plurality of photosensitive openings; the touch layer comprises a plurality of touch wires, and the orthographic projection of the touch wires on the substrate surrounds the orthographic projection of the photosensitive opening on the substrate in a non-closed manner. According to the technical scheme, the use performance of the display panel is improved.
