example 1

[0035] Such as Figure 1a and Figure 1b As shown, in this example, the glue structure 03 is fixed at one or more places between the flexible module 01 and the flexible support structure 02, that is, the glue structure 03 does not completely connect the surfaces of the flexible module 01 and the flexible support structure 02 They are fixed together so as to ensure that the flexible module 01 and the flexible support structure 02 can slide relative to each other when the flexible device is bent.

[0036] In practice, the location of the glue structure 03 in this example can be anywhere between the flexible module 01 and the flexible support structure 02, and the location of the glue structure 03 can be one place or multiple places. Preferably, if Figure 1a and Figure 1b As shown, the glue structure 03 is only fixed at one of the flexible modules 01 and the flexible support structure 02, for example, as Figure 1a and Figure 1b As shown, it is fixed at the edge position of ...

example 2

[0046] Such as Figure 4a and Figure 4b As shown, in this example, the glue structure 03 fills the entire area between the flexible module 01 and the flexible support structure 02; In order to enable the flexible module 01 and the flexible support structure 02 to slide relative to each other when the flexible device is bent, the adhesive structure 03 needs to be elastically deformed when the flexible device is bent. Therefore, the adhesive structure 03 should be selected with a very low elastic modulus. The adhesive material is used to ensure that it can undergo elastic deformation. Specifically, the elastic modulus of the adhesive structure is 80pa-500Mpa.

[0047] In the above two examples, there are two kinds of adhesives that can not only fix the flexible module 01 and the flexible support structure 02 to each other, but also enable the flexible module 01 and the flexible support structure 02 to slide relative to each other when the flexible device is bent. The implemen...

Abstract

The invention discloses a flexible device, comprising: a flexible module, a flexible supporting structure opposite to the flexible module, and fixing the flexible module and the flexible supporting structure to each other and making the flexible module and the flexible A glue structure in which the supporting structure slides relative to each other. Through the adhesive structure, while the flexible module and the flexible support structure are fixed to each other, there is room for relative movement between the two when the flexible device is bent. Therefore, the flexible module and the flexible support structure are connected through the adhesive structure. When the structure is integrated into a complete machine, the flexible module and the flexible supporting structure are relatively independent, and the position of the neutral layer in the flexible module will not be changed, thus reducing the cracking between the film layers in the flexible module during the bending process possibility, and the flexible device can be bent to a lower bending radius with the same thickness of the flexible module.

Description

technical field [0001] The present invention relates to the technical field of flexible display, in particular to a flexible device. Background technique [0002] At present, flexible modules that can be bent or folded have been developed. The flexible module is a multi-layer structure. For example, a flexible display panel designed based on an electroluminescent structure generally includes a laminated back film, a pixel control circuit, Electroluminescent pixel components, water and oxygen barrier layer (BF), circular polarizer (C-POL), touch component (Touch), and protective cover (HC) and other film layers, usually the overall thickness of the module is 200- 600 μm. [0003] When the flexible module and the supporting and fixing mechanical structure are integrated into a complete machine, the mechanical structure and the flexible module are all attached and fixed together, which is equivalent to indirectly increasing the thickness of the overall flexible module and chan...
