Problems solved by technology

[0003] Existing flexible display panels use flexible materials to prepare cover plates and substrates to make them bendable to a certain extent. However, after the adhesive layer is cured, the bendability of the flexible substrate 1 or the transparent flexible cover plate 2 is relatively poor. When the flexible display panel is bent too much, such as figure 2 as shown, figure 2 for figure 1 The schematic diagram of the structure of the flexible display panel when it is bent will cause the adhesive layer 3 to have the problem of peeling as shown in A and the problem of breaking as shown in B
From the above description, it can be seen that the adhesive layer part of the flexible display panel of the existing structure has poor bendability, which in turn leads to poor bendability of the flexible display panel.

Embodiment 1

[0042] As mentioned in the background art, the existing flexible display panel will cause the adhesive layer to peel off or break when it is bent, which makes the flexible display panel poor in bendability, and the flexible display panel is prone to damage when it is bent, which affects its use. life.

[0043] The inventors of the present invention have found that elastic components are installed in the adhesive layer of the flexible display panel to disperse and buffer the stress generated when the flexible display panel is bent, which can effectively improve the bendability of the flexible display panel and prevent it from being damaged when it is bent. The problem of peeling or breaking of the adhesive layer makes it not easy to be damaged when it is bent, ensuring its service life.

[0044] Based on the above research, this embodiment provides a flexible display panel, referring to image 3 , image 3 It is a schematic structural diagram of a flexible display panel when ...

Embodiment 2

[0051] For the implementation of the flexible display panel described in Embodiment 1, please refer to Figure 4 and Figure 5 , Figure 4 It is a schematic structural diagram of the frame area of ​​the flexible display panel provided by Embodiment 2 of the present invention, Figure 5 It is a top view of the frame area, and a plurality of elastic components 34 are arranged at equal intervals in the adhesive layer 33. Since the elastic components 34 are arranged at equal intervals, the layout is simple, which can make the production of the flexible display panel simple.

[0052] The implementation of the flexible display panel described in the first embodiment can also refer to Figure 6 and Figure 7 , Figure 6 It is a schematic structural diagram of a frame area of ​​another flexible display panel provided in Embodiment 2 of the present invention, Figure 7 for Figure 6 As shown in the top view of the frame area, in the adhesive layer 33 on each side of the frame area,...

Embodiment 3

[0055] Based on the above embodiments, this embodiment provides a flexible display panel, referring to Figure 8 , Figure 8 It is a structural schematic diagram of a flexible display panel provided by Embodiment 3 of the present invention. The elastic member 34 provided in the adhesive layer 33 of the flexible display panel is cylindrical, and the cylindrical elastic member 34 has a simple structure and a simple forming process.

[0056] In this embodiment, the diameter of the cylinder may be set to range from 200 μm to 400 μm, including endpoints. The cylinder density is 10%-30%, including the endpoint value, that is, the area of ​​the frame area occupied by all cylinders is 10%-30%.

[0057] The flexible display panel in this embodiment can be bent in two directions, on the one hand, it can be bent towards the direction of the flexible substrate 31 , and on the other hand, it can also be bent towards the direction of the transparent flexible cover plate 32 .

Abstract

The invention discloses a flexible display panel, a production method for the same, and a flexible display device. The flexible display panel comprises a flexible substrate and a transparent flexible cover plate which are oppositely arranged; the flexible display panel is provided with a display area and a border area surrounding the display area; a rubber layer is arranged in the border area, and used for bonding and fixing the flexible substrate and the transparent flexible cover plate; a plurality of elastic components are arranged in the rubber layer. The flexible display panel is good in bendability. The production method can be used for producing the flexible display panel with good bendability, and the flexible display device is produced by the flexible display panel and good in bendability.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a flexible display panel, a manufacturing method thereof, and a flexible display device. Background technique [0002] refer to figure 1 , figure 1 It is a structural schematic diagram of a common flexible display panel in the prior art. The flexible display panel includes: a flexible substrate 1 and a transparent flexible cover 2 disposed opposite to each other, and an adhesive layer 3 disposed in the frame area of ​​the flexible substrate 1 . Wherein, the adhesive layer 3 is used for bonding and fixing the flexible substrate 1 and the transparent flexible cover 2 , and is used for sealing and protecting the display device on the flexible substrate 1 . [0003] Existing flexible display panels use flexible materials to prepare cover plates and substrates to make them bendable to a certain extent. However, after the adhesive layer is cured, the bendabil...
