Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a plurality of pixel driving circuits and a light shielding layer. Each pixel driving circuit comprises a plurality of transistors, and the orthographic projection of an active layer of each transistor on the substrate and the orthographic projection of a first electrode layer on the substrate have an overlapping part. The light shielding layer is arranged in a transition display area of the display panel and located between the substrate and the active layer of each transistor of the pixel driving circuit, and the orthographic projection of the light shielding part on the substrate covers the orthographic projections of the overlapping parts on the substrate, so that the light shielding layer can effectively shield infrared light emitted by an emission sensor of an optical sensing unit, the interference effect of the infrared light on a transistor device arranged in the transition display area is avoided, and the flicker phenomenon of a camera area under the screen is prevented.

Description

Technical field [0001] The present invention relates to display technology, and particularly relates to a display panel and a display device. Background technique [0002] TOF (Time of Flight, TOF) is the use of optical technology to measure the time of flight distance, has been widely used in areas such as smart phones face recognition, 3D structure compared to the light, it has a detection distance, simple structure advantage. [0003] The way to realize screen camera (Camera Under Panel, CUP) technology is mounted TOF technology transmitting and receiving ends respectively TOF camera placed below the region of the lower two panel camera. However, TOF camera is an infrared laser light source generates an infrared transmitter and receiver to obtain depth information, in practical applications, the infrared light emitted by the transmitter TOF camera be provided over the transistor devices interfere with the camera, so that the screen the lower region of the screen flickers camer...
