Abstract

The present application discloses a display panel and a display device. The display panel includes a functional display area and a conventional display area. The display panel further includes a substrate, a light-emitting layer and a touch layer sequentially disposed on the substrate. The touch layer includes an opening disposed in the functional display area, a barrier portion disposed around the opening, and a touch portion located on a side of the barrier portion away from the opening; wherein at least a part of the barrier portion is disposed in the functional display area.

3 . The display panel according to claim 2 , wherein a minimum distance between each of the second metal grids and each of the second light-emitting pixels corresponding thereto is greater than a minimum distance between each of the first metal grids and each of the first light-emitting pixels corresponding thereto.

4 . The display panel according to claim 3 , wherein the minimum distance between each of the second metal grids and each of the second light-emitting pixels corresponding thereto is greater than a minimum distance between each of the second metal grids and each of the first light-emitting pixels corresponding thereto.

5 . The display panel according to claim 3 , wherein an area of the second light-emitting pixels of a first color is smaller than an area of the first light-emitting pixels of the first color, and the first color comprises any color of red, green, and blue.

6 . The display panel according to claim 2 , wherein the barrier portion is provided with at least two of the second metal grids in a direction away from a center of the opening.

7 . The display panel according to claim 2 , wherein a line width in the second metal grids is less than or equal to a line width in the first metal grids.

8 . The display panel according to claim 2 , wherein a part of the first metal grids is further disposed corresponding to the second light-emitting pixels and is not overlapped with the second light-emitting pixels corresponding thereto, and the second metal grids are disposed corresponding to the second light-emitting pixels and are not overlapped with the second light-emitting pixels corresponding thereto.

9 . The display panel according to claim 1 , wherein the functional display area comprises a euphotic display sub-area, and a transition sub-area between the euphotic display sub-area and the conventional display area;

at least part of the barrier portion is disposed in the transition sub-area.

10 . The display panel according to claim 9 , wherein the barrier portion is disposed outside the euphotic display sub-area.

11 . A display device, comprising a display panel and a camera assembly, wherein the display panel comprises a functional display area, and a conventional display area disposed around the functional display area, and the camera assembly is disposed on a side of the display panel and corresponding to the functional display area;

wherein the display panel further comprises:

a substrate;
