Embodiment 1

[0043] see figure 2 and image 3 The cover structure of the flexible display module provided in this embodiment is used to cover the surface of the flexible display module. On the one hand, it can provide protection for the flexible display module; Provide users with a good touch feel. The cover plate structure includes an organic cover plate layer 10 and a flexible glass layer 11 that are attached together. Specifically, the material of the organic cover layer 10 is generally polyimide (PI), and may also be polyethylene terephthalate (PET) or other organic materials. In this embodiment, the thickness of the organic cover layer 10 is 60-90 microns. The flexible glass layer 11 is bendable glass, generally ultra-thin glass (UTG). An adhesive layer 12 is generally arranged between the organic cover layer 10 and the flexible glass layer 11, and the adhesive layer 12 bonds the organic cover layer 10 and the flexible glass layer 11 together; the material of the adhesive layer 1...

Embodiment 2

[0054] Same as the above-mentioned embodiment 1, in this embodiment, the cover plate structure of the flexible display module also includes the attached organic cover plate layer 10 and the flexible glass layer 11; and the flexible glass layer 11 also includes the first part 111 and the second part 112 , the thickness of the first part 111 is greater than the thickness of the second part 112 .

[0055] Such as Figure 6 and Figure 7 As shown, in this embodiment, the side of the flexible glass layer 11 facing the organic cover layer 10 is planar and parallel to the organic cover layer 10 . The portion of the first portion 111 of the flexible glass layer 11 that is thicker than the second portion 112 protrudes from the side of the flexible glass layer 11 facing away from the organic cover layer 10 .

[0056] In this embodiment, the thickness of the first part 111 of the flexible glass layer 11 is greater than the thickness of the second part 112. Therefore, the same as the ab...

Embodiment 3

[0061] Same as the first embodiment above, in this embodiment, the cover structure of the flexible display module also includes an organic cover layer 10 and a flexible glass layer 11 that are bonded together.

[0062] Different from the above-mentioned embodiment 1 and embodiment 2, in this embodiment, as Figure 8 and Figure 9 As shown, the flexible glass layer 11 is only disposed on the area of ​​the cover structure corresponding to the non-bending area of ​​the flexible display module. In other words, no flexible glass layer 11 is provided in the bendable area.

[0063] In order to fill the gap in the area where the flexible glass layer 11 is not provided in the above-mentioned bendable area, a filling layer arranged on the same layer as the flexible glass layer 11 is provided in the area of ​​the cover structure corresponding to the bendable area of ​​the flexible display module 14 , the filling layer 14 can enable other layer structures on both sides of the flexible g...

Abstract

The invention relates to a cover plate structure of a flexible display module, the flexible display module and flexible display equipment. The cover plate structure of the flexible display module comprises an organic cover plate layer and a flexible glass layer which are attached to each other, the flexible glass layer is provided with a first part and a second part, the first part is located in an area, corresponding to a bendable area of the flexible display module, on the cover plate structure, and the second part is located in an area, corresponding to a non-bending area of the flexible display module, on the cover plate structure; the first part of the flexible glass layer is thicker than the second part; or the flexible glass layer is only arranged in the area, corresponding to the non-bending area of the flexible display module, of the cover plate structure. According to the scheme, the overall resilience force of the flexible display module can be reduced when the flexible display module is bent, and attachment between the layers of structures can be better maintained. In addition, the dislocation amount of the edge of the supporting layer when the flexible display module is bent can be reduced, and therefore the probability that a Pad bending area of the flexible display module is damaged in a jacking mode is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cover structure of a flexible display module, a flexible display module and a flexible display device. Background technique [0002] The organic light emitting diode display (Organic Light Emitting Display, OLED) screen can also have a certain degree of flexibility and adaptability. Based on this feature, the OLED display screen can be prepared as a flexible display module, which is applied to different forms of folding and curling. Products such as folding mobile phones and various wearable devices such as watches and bracelets. [0003] figure 1 It is a structural schematic diagram of an existing flexible display module. Such as figure 1 As shown, the flexible display module includes polyimide layer (PI) 1 , ultra-thin glass (UTG) 2 , polarizer 3 , display screen 4 , back film 5 , and support layer 6 . Among them, the polyimide layer 1 and the ultra-thin glass 2 are comb...
