Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, a light-emitting function layer arranged on the array substrate and a packaging layer covering the light-emitting function layer on the array substrate, and the array substrate is provided with at least one first partition groove in the periphery of an open hole; the first partition groove is configured to at least enable the inorganic packaging layer to be disconnected at the first partition groove; according to the display panel and the display device, cracks of the inorganic packaging layer from the packaging layer can be prevented from extending to the display area of the display panel, so that failure of a light emitting device in the display area can be prevented, and the reliability and the stability of the display panel are improved.

Description

Technical field[0001]The present invention relates to the field of display, in particular a display panel and a display device.Background technique[0002]The LED device has the advantages of light weight, wide viewing angle, fast response time, low temperature and luminous efficiency, so that the industry has always been regarded as the next generation of new display technology, especially OLED, in the display industry, especially OLED. It is a huge advantage of the OLED display panel.[0003]In order to improve the screen of the OLED panel, panel manufacturers have successively launched Liu Haiping, water dripping screen, and beautiful tips. However, the shaped cutting portions of such panels are concentrated on the edge of the panel display area, and thus the flexibility of the screen camera, infrared sensor, and earpiece cannot be realized. In view of this, it is necessary to develop a new type of panel that enables a screen camera, an infrared sensor, and an editor.[0004]figure 1 F...
