Embodiment 1

[0054] This embodiment aims at that when the existing flexible display device is bent, the hardened sealant often makes it difficult to bend, and even in the process of bending, the hardened sealant is damaged due to greater stress, thus affecting the In order to solve the problem of product reliability, a frame sealant and its preparation method are provided. The frame sealant has excellent bending properties and can effectively relieve the stress on the frame of the flexible display panel when it is bent, thereby avoiding the failure of the flexible display panel when it is folded. Or defects occur during the bending process, thereby ensuring that the sealant in the flexible display panel is damaged.

[0055] The flexible frame tape includes at least a base material and adhesive layers symmetrically arranged on both sides of the base material, wherein the base material is an elastomer material, and the adhesive layer is formed of a material including an elastomer material and...

Embodiment 2

[0084] This embodiment provides a display panel, the display panel includes a flexible display module, and the flexible display module is packaged with the sealant in Embodiment 1. The frame sealant can effectively relieve the stress on the frame of the flexible display device when it is bent, and while realizing the flexible display, it also has a better packaging effect and can ensure its performance when being folded or bent.

[0085] Wherein, the flexible display module here may be an LCD display device or an OLED display device.

[0086] In the flexible display panel of this embodiment, if figure 2 As shown in the cross-sectional view of the concave-convex structure shown, both sides of the flexible display panel are respectively provided with a flexible cover 12 (Cover Film) and a middle frame 14, the flexible cover 12 is used to protect the display module 11, and the middle frame 14 is used to support The display module 11, the flexible cover 12 and the middle frame 1...

Abstract

The invention belongs to the field of display technology, and particularly relates to a frame sealing adhesive, a preparation method thereof, a display panel and a preparation method thereof. The frame sealing adhesive comprises a substrate and an adhesive layer arranged on at least one side of the substrate, wherein the substrate is a first elastomer material; the adhesive layer comprises a second elastomer material and a crosslinking agent. Both the substrate and the adhesive layer of the frame sealing adhesive are made of elastomer materials, and the adhesive layer also contains the crosslinking agent to adjust the storage modulus of the adhesive layer, so that the frame sealing adhesive has high bending performance at the same time, can bear larger stress, and has higher viscosity to ensure that the frame sealing adhesive does not come apart when the display panel is folded. Thus, damage of the frame sealing adhesive during folding or bending of a flexible display panel can be avoided, and high packaging performance is ensured.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a frame sealing glue and a preparation method thereof, a display panel and a preparation method thereof. Background technique [0002] Currently, commonly used flat panel display devices include LCD (Liquid Crystal Display: Liquid Crystal Display) and OLED (Organic Light-Emitting Diode: Organic Light-Emitting Diode) display devices. [0003] Existing OLED display devices and LCD display devices both include a plurality of film layers or material layers, and a frame sealant is used as an adhesive member at the frame position. The main component of the frame sealant is resin, which is divided into two basic types: heat curing type and light curing type, which are compressed by heating and pressure and then hardened to achieve the sealing effect. For example, currently, in the process of manufacturing LCD display devices, the array substrate and the color filter substr...
