Problems solved by technology

[0003] However, since the area of ​​the display panel corresponding to the under-screen functional device needs to have both display and light transmission performance, the device structure or film layer structure of the display area corresponding to the functional device is different from the normal display area, which may easily lead to the failure of the functional device. The brightness attenuation difference between the corresponding display area and the normal display area at the side view angle is relatively large, which causes the problem that the boundary between the display area corresponding to the functional device and the normal display area of ​​the display panel is relatively obvious at the side view angle, making the display panel in the Display uniformity is poor at side view angles

Abstract

The invention discloses a display panel and a display device, relates to the technical field of display, and can balance the brightness attenuation of a display area corresponding to a functional device of an existing display panel and a normal display area at a side view angle and improve the display uniformity of the display panel at the side view angle. The display panel comprises a substrate, the substrate comprises a first display area and a second display area at least partially surrounding the first display area, and the light transmittance of the first display area is larger than that of the second display area; the plurality of first sub-pixels comprise a plurality of first pixel circuits and a plurality of first light-emitting elements, and the plurality of first light-emitting elements are located in the first display area; the plurality of second sub-pixels comprise a plurality of second pixel circuits and a plurality of second light-emitting elements, and the plurality of second pixel circuits and the plurality of second light-emitting elements are located in the second display area; the color filter film is at least located in the first display area, and the color filter film comprises a plurality of filter units; and the dimming structures are positioned between the adjacent filtering units.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, the application of under-screen functional devices is becoming more and more extensive. For example, setting the front camera as the under-screen camera does not require cutting and digging holes in the display panel, which can avoid setting the camera position to occupy the display area and reduce the screen size. proportion. [0003] However, since the area of ​​the display panel corresponding to the functional device under the screen needs to have both display and light transmission properties, the device structure or film layer structure of the display area corresponding to the functional device is different from the normal display area, which may easily lead to functional devices. The brightness attenuation difference between the corresponding disp...
