Embodiment Construction

[0023] The specific implementation manner of the flexible device provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] The thickness and shape of each film layer in the drawings do not reflect the true scale of the flexible device, but are only intended to schematically illustrate the content of the present invention.

[0025] An embodiment of the present invention provides a flexible device, including: a flexible module, and a flexible support structure fixed on the surface of the flexible module for dispersing stress.

[0026] In the above-mentioned flexible device provided by the embodiment of the present invention, a flexible support structure for dispersing stress is fixed on the surface of the flexible module. During the use of the flexible device, the flexible support structure can absorb the point-like force or The linear force is dispersed into a relatively uniform planar force, and ...

Abstract

The invention discloses a flexible device. A flexible supporting device used for dispersing stress is fixed on the surface of a flexible module; the flexible supporting device can disperse dot force or linear force applied to the flexible device which is bent into uniform planar force during the use of the flexible device, meanwhile can reduce the stress applied to the flexible module, and avoid the problem of cracking of film layers due to local stress concentration on the flexible module. Moreover, the flexible device can be bent to obtain smaller bending radius in the condition of 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 50- 1500μm. [0003] The bonding force between the cathode and the light-emitting layer in the electroluminescent pixel component of the flexible module is van der Waals force, which is the weakest link compared to the bonding force between other film layers, and it is easy to occur during repeated bending. cracking.
