Problems solved by technology

[0003] However, due to the obvious cathode thickness difference between the light-transmitting area and the area outside the light-transmitting area, there is an obvious cathode step difference at the boundary of the light-transmitting area, resulting in obvious brightness unevenness at the boundary of the light-transmitting area, Reduced display panel brightness uniformity

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first display area and a second display area, the light transmittance of the first display area is larger than that of the second display area, in the first display area, and the display panel comprises pixel areas and light-transmitting areas located between the pixel areas. The display panel comprises: a light-emitting unit layer; an auxiliary layer comprising at least one auxiliary part, wherein the auxiliary part is located in the corresponding light-transmitting area; and a first electrode layer arranged on the light-emitting unit layer and the auxiliary layer. The auxiliary part comprises a platform part and an edge part located at the edge of the platform part, the first electrode layer covers the light-emitting unit layer and at least part of the edge part, and the thickness of the first electrode layer located on the edge part is smaller than that of the first electrode layer located on the light-emitting unit layer. The cathode segment difference at the boundary of the light-transmitting area is reduced, the phenomenon of uneven brightness at the boundary of the light-transmitting area is weakened, and the brightness uniformity of the display panel is improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] In the existing under-screen camera display technology (Camera Under Panel, CUP), the display panel includes a first display area for both display and shooting and a second display area only for display, in order to improve the shooting effect of the camera Generally, the cathode in the light-transmitting area in the first display area is removed to increase the light transmittance of the display panel in this area. [0003] However, due to the obvious cathode thickness difference between the light-transmitting area and the area outside the light-transmitting area, there is an obvious cathode step difference at the boundary of the light-transmitting area, resulting in obvious brightness unevenness at the boundary of the light-transmitting area, The brightness uniformity of the display panel is reduced.
