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

Abstract

The embodiment of the invention provides a display panel, a preparation method thereof, and a display device, and relates to the technical field of display. A resin adhesive layer can be prevented from being stripped from a substrate when the display panel is bent. The display panel comprises a substrate, and an OLED device and an encapsulation layer which are successively disposed on the substrate, wherein the encapsulation layer at least comprises a resin adhesive layer disposed on a side of the OLED device. The display panel further comprises at least one a first fixing member, wherein thefirst fixing member includes a fixing portion, and the fixing portion includes a first portion and a second portion. The substrate includes a first groove at a side close to the OLED device. The firstportion is embedded in the first groove, and the second portion is completely embedded in the resin adhesive layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Since the Organic Light-Emitting Diode (OLED) display panel has a high color gamut and can realize ultra-thin and flexible display, it has gradually received widespread attention. In particular, curved flexible OLED display panels are favored by many consumers because of their unique functions and excellent user experience. [0003] The OLED display panel includes an OLED device, which is easily corroded by water vapor and oxygen. The light-emitting functional layer and electrode layer in the OLED device are very easy to react with water and oxygen, resulting in the failure of the OLED device. Therefore, the OLED device needs to be packaged in order to Extend the service life of OLED devices. [0004] In the prior art, OLED devices are usually packaged with resin adhesive mater...
