Problems solved by technology

[0003] However, in the design of the camera under the OLED screen, since it is necessary to open a mounting hole for the camera in the screen, it will cause water vapor to easily enter the pixel area of ​​​​the OLED device from the mounting hole area, which will lead to a decline in the luminous performance of the OLED device, or even not working problem

Abstract

The invention relates to a display panel and a display device. The display panel comprises a substrate, a light-emitting structure layer and a packaging structure layer, wherein the substrate comprises an opening area, a spacing area and a display area, the opening area and the display area are spaced apart by the spacing area, and the opening area isused for mounting a camera; the light-emittingstructure layer is arranged on the substrate; the side, deviating from the substrate, of the light-emitting structure layer protrudes to form at least two circles of dams arranged at intervals, the atleast one circle of dam is located on the display area and surrounds the edge of the interval area, the at least one circle of dam is located on the opening area and surrounds the edge of the openingarea, the side, away from the substrate, of the light-emitting structure layer is sunken to form at least one groove, and the groove is located on the interval area and surrounds the opening area; and the packaging structure layer is arranged on the light-emitting structure layer. Thus, the water-oxygen blocking capability at the edge of the opening area can be enhanced, the path of water-oxygenpermeating from the opening area to the display area is prolonged, the production yield of the display panel is further improved, and the service life is prolonged.

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] As consumers' demand for screen-to-body ratio increases, under-screen camera-type OLED display panels have become one of the mainstream design solutions in the field of OLED display panels. [0003] However, in the design of the camera under the OLED screen, since a mounting hole for setting the camera needs to be opened in the screen, it will cause the water vapor to easily enter the pixel area of ​​the OLED device from the mounting hole area, thereby causing the luminous performance of the OLED device to decrease, and even Not working problem. [Content of the invention] [0004] The purpose of the present application is to provide a display panel and a display device to prevent water vapor from penetrating from the camera mounting hole area to the pixel area, thereby improving production ...
