Abstract

The invention discloses a display panel and a display device. The display panel comprises a function additional area and a main display area surrounding the function additional area, and the display panel comprises a plurality of pixel rows, a plurality of auxiliary pixel driving circuits, a plurality of main pixel driving circuits and a multi-stage gate driving circuit; the multi-stage gate drive circuit is connected to the multiple auxiliary pixel drive circuits and the multiple main pixel drive circuits through the multiple scanning signal lines, and each stage of scanning signal lines comprises P main scanning signal lines and Q auxiliary scanning signal lines. According to the array substrate, the Z first auxiliary scanning signal lines in the Q auxiliary scanning signal lines are connected with the corresponding gate driving circuits, the other second auxiliary scanning signal lines are disconnected, and a connecting wire for connecting the two auxiliary scanning signal lines does not need to be arranged, so the phenomenon that the connecting wire and the pixel driving circuits are easily coupled is avoided.

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] When using the under-screen camera (Camera Under Panel, CUP) technology, in order to reduce the impact of the pixel drive circuit that drives the pixels in the CUP area to emit light on the CUP area, one pixel drive circuit will simultaneously drive multiple sub-pixels in the CUP area. At the junction of the main display area and the CUP area, at least two scanning signal lines are merged into one line through the connecting line and connected to the pixel driving circuit in the CUP area. Coupling between the connecting line and the pixel driving circuit is prone to occur , thus affecting the normal display. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device to solve the problem that at least two scanning signal lines of the existing di...
