Abstract

The invention discloses a display panel and a display device. The display panel includes a first display area and a second display area. The light transmittance of the first display area is greater than that of the second display area. In the first display area, The display panel includes a pixel area and a light-transmitting area located between the pixel areas. The display panel includes: a light-emitting unit layer; an auxiliary layer, including at least one auxiliary part, and the auxiliary part is located in the corresponding light-transmitting area; the first electrode layer is arranged in the on the light-emitting unit layer and the auxiliary layer; wherein, the auxiliary portion includes a platform portion and an edge portion located at the edge of the platform portion, the first electrode layer covers the light-emitting unit layer and at least part of the edge portion, and the thickness of the first electrode layer on the edge portion is less than The thickness of the first electrode layer on the light emitting unit layer. The invention ensures that the cathode step 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 reduced, and the brightness uniformity of the display panel is improved.

Description

technical field

[0001] The present invention relates to the field of display, 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 used for both display and shooting and a second display area only used for display, in order to improve the shooting effect of the camera , the cathode of the light-transmitting region in the first display region is usually removed to improve the light transmittance of the display panel in this region.

[0003] However, due to the obvious difference in cathode thickness between the light-transmitting area and the area other than 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. SUM...
