Display panel and display device

Abstract

The invention discloses a display panel and a display device, a pixel driving circuit of the display panel comprises a first type pixel driving circuit located in a second display area, the first typepixel driving circuit comprises a first pixel driving circuit, the light-emitting elements comprise a first light-emitting element located in the high-light-transmittance area, the first light-emitting element is electrically connected with the first pixel driving circuit through an anode signal line arranged on the substrate, a coupling structure is also arranged on the substrate base plate, each pixel driving circuit comprises a driving transistor and a connecting wire electrically connected with a grid electrode of the driving transistor, in the first direction, the connecting line of eachfirst type pixel driving circuit and the anode signal line and / or the coupling structure have / has a first overlapping region, and the sum of the areas of the first overlapping regions corresponding to the first type pixel driving circuits is within a first preset range. According to the embodiment of the invention, the display uniformity of the display panel can be improved, and the display effect of the display panel is further improved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel and a display device. Background technique [0002] With the development of display technology, display devices are gradually progressing from narrow bezels to borderless visual effects to increase the screen-to-body ratio of the display device. The optical sensor modules of the display device with a high screen-to-body ratio, such as cameras and infrared sensors etc., will be arranged in its display area, and in order to make the area where the optical sensor module is installed have a higher light transmittance, the pixel density in the area where the optical sensor module is installed is usually reduced. [0003] At present, how to ensure the display uniformity of the display device under the premise of further increasing the light transmission area of ​​the optical sensor module installation area has become an urgent technical problem to be solv...
