Display panel, manufacturing method thereof, and display device

Abstract

Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device, which relate to the field of display technology and can prevent the resin adhesive layer from being peeled off from the substrate when the display panel is bent. A display panel, comprising a substrate, an OLED device sequentially disposed on the substrate, and an encapsulation layer, the encapsulation layer comprising a resin glue layer disposed at least on the side of the OLED device; the display panel also includes at least one The first fixing part, the first fixing part includes a fixing part, the fixing part includes a first part and a second part; the side of the substrate close to the OLED device includes a first groove, and the first part is embedded in the OLED device. In the first groove, the second part is completely embedded in the resin adhesive layer.

Description

Technical field [0001] The present invention relates to the field of display, and more particularly to a display panel and a preparation method thereof, a display device. Background technique [0002] Due to the organic Light-Emitting Diode, referred to as an OLED display panel, ultra-thin and flexible display can be achieved, which has gradually received extensive attention. In particular, the flexible OLED display panel of the surface is favored by many consumers because of its unique function and excellent user experience. [0003] The OLED display panel includes an OLED device, which is easily eroded by water vapor and oxygen, and the luminescent functional layer and the electrode layer in the OLED device can be easily reacted with oxytic oxygen, resulting in failure of the OLED device, and therefore, it is necessary to package the OLED device. Extend the service life of the OLED device. [0004] In the prior art, the resin rubber material is usually encapsulated by the OLED ...

AI Technical Summary

Problems solved by technology

[0005] However, since the materials currently used for the substrate of the OLED display panel are usually glass, polyimide (Polyimide, PI for short), etc., the adhesion between the resin adhesive material and glass, PI, etc. has certain limitations, such as figure 1 As shown, in the process of cutting, handling, and assembling the OLED display panel in the later stage, it is easy to bend the layers in the OLED display panel (for example, the substrate 10, the OLED device 11, and the encapsulation layer 12), thereby causing the encapsulation layer The resin adhesive in 12 is peeled off from the substrate 10, water vapor and oxygen enter the OLED device 11, affecting the life of the OLED device 11
