Problems solved by technology

[0003] Since the edges of OLED devices are easily invaded by water vapor and oxygen, it will cause phenomena such as electrode oxidation, poor chemical reaction of organic materials or black spots, which will reduce the service life of OLED devices.
In the existing packaging method, materials that can improve the ability of the OLED device to block water and oxygen are usually placed on the edge of the OLED device, but this will result in a larger frame of the OLED display panel

Abstract

The OLED display panel provided by the invention comprises a light emitting substrate and at least one group of encapsulation films arranged on the light emitting substrate. Wherein each group of theencapsulation films includes a first inorganic layer disposed on the light emitting substrate, the edge region of the first inorganic layer is provided with a retaining wall, the first inorganic layeris provided with an organic layer and the organic layer is blocked in the retaining wall, and the organic layer is provided with a second inorganic layer covering the first inorganic layer, the organic layer and the retaining wall; wherein the retaining wall is provided with a zigzag structure capable of improving the water-oxygen barrier performance of the OLED display panel. By installing a retaining wall with a zigzag structure on the OLED display panel, not only the ability of the OLED display panel to block water and oxygen can be improved, but also the frame of the OLED display panel can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, organic light-emitting diode), as a current-type light-emitting device, is widely used because of its advantages such as self-illumination, rich colors, fast response speed, wide viewing angle, light weight and flexible display. focus on. [0003] Since the edge of the OLED device is easily invaded by water vapor and oxygen, it will cause phenomena such as electrode oxidation, poor chemical reaction of organic materials, or black spots, thereby reducing the service life of the OLED device. In the existing packaging method, materials that can improve the ability of the OLED device to block water and oxygen are usually placed on the edge of the OLED device, but this will result in a larger frame of the OLED display panel. Contents of the invention [0004] An embodimen...
