Problems solved by technology

At present, when the high-temperature and high-humidity reliability test is performed on the panel, the problem of black spots on the edge of the screen is prone to appear. The gas generated by the decomposition is easy to break through the surrounding film layer, making the outside water and oxygen invade the inside of the panel, causing the screen to fail, and black spots appear on the edge of the screen

Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate including a display area and a non-display area located at the periphery of the display area; a planarization layer located on the substrate, wherein a groove surrounds the display area on the corresponding planarization layer in the non-display area; an anode covering the upper surface of the planarization layer, wherein a through hole is formed in the anode and penetrates through the upper and lower surfaces of the anode. The display panel and the display device, while preventing an organic layer from overflowing, ensure that a screen body does not generate a black spot problem in a subsequent high-temperature and high-humidity reliability test, thereby improving the reliability of the panel and prolonging the service life 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] The organic light emitting diode (Organic Light Emitting Diode, OLED) display device has many advantages such as fast response speed, wide color gamut, and good flexibility, and is more and more widely used in the display field. At present, when the high-temperature and high-humidity reliability test is performed on the panel, the problem of black spots on the edge of the screen is prone to appear. The gas generated by the decomposition is easy to break through the surrounding film layer, making the outside water and oxygen invade the inside of the panel, causing the screen to fail, and black spots appear on the edge of the screen. Contents of the invention [0003] In order to solve the above problems, the present invention provides a display panel and a display device, which can ensure that black sp...
