Embodiment Construction

[0030] Currently, such as figure 1 As shown, for a display panel with a hole 01 in the display area A, the hole-digging process on the display panel will directly expose the vapor-deposited film on the entire surface, and external water vapor will enter through the hole and oxidize the vapor-deposited film. To prevent water vapor from entering, usually multiple ring-shaped trenches 02 are set around the external control, which can directly isolate the vapor deposition film naturally during the vapor deposition process to prevent water vapor from intruding. But like figure 1 As shown, when the vapor deposition film layer is not completely blocked at a certain part of an annular groove, water vapor will invade the oxidation vapor deposition film along the uninterrupted point 021. When there are uninterrupted at different positions of multiple annular grooves at the same time When it is clicked, water vapor will invade layer by layer along the direction parallel to the boundary of ...

Abstract

The invention relates to the technical field of display, and discloses a display panel and a display device. The display panel comprises a substrate, an evaporation film layer arranged on one side ofthe substrate and a packaging layer arranged on the side of the evaporation film layer deviating from the substrate. The display panel comprises a display area and a first non-display area. The display area at least semi-surrounds the first non-display area. The first non-display area comprises a through hole and a partition structure positioned between the through hole and the display area. The partition structure is arranged between the surface of the side of the substrate away from the evaporation film layer and the evaporation film layer. The partition structure includes a plurality of annular partition grooves surrounding the through hole and at least one radial partition groove extending toward the through hole between at least two adjacent annular partition grooves. The groove portsof the annular partition grooves and the radial partition grooves facing the evaporation film layer. The radial partition grooves between the two adjacent annular partition grooves in the display panel can prevent water vapor from invading the evaporation film layer layer by layer in the direction parallel to the through hole boundary so as to improve the reliability of the display panel.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, in order to maximize the screen occupancy of the display panel, a camera is sometimes provided in the display area of ​​the display panel, and this structure requires a hole for placing the camera in the display area of ​​the display panel. For organic electroluminescent film that needs to be vapor-deposited on the entire surface, the digging process on the display panel will cause the side of the vapor-deposited film on the entire surface to be directly exposed to the outside, and water vapor will enter the oxidized vapor-deposition film from the digging hole. Lead to package failure. Summary of the invention [0003] The present invention provides a display panel and a display device. The display panel is used to solve the problem that water vapor invades the vapor-deposited film layer by layer ...
