Problems solved by technology

However, the metal material itself is difficult to bend, and stress concentration problems often occur when bending, resulting in creases in the bending area of ​​the supporting part, and also prone to creases in other laminated layers of the flexible display module.
Furthermore, the display device made by using the flexible display module will also have poor display in the bending area, which will reduce the user experience.

Embodiment Construction

[0041] In order to explain the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and drawings. Similar components in the drawings are denoted by the same reference numerals. Those skilled in the art should understand that the content described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0042] It should be noted that "on", "formed on" and "disposed on" in this article can mean that one layer is directly formed or disposed on another layer, or can mean a A layer is formed indirectly or arranged on another layer, that is, there are other layers between the two layers. In this document, unless otherwise specified, the term "located on the same layer" means that two layers, parts, components, elements or parts can be formed by the same patterning process, and the two layers, parts, components, The elements or parts are generally form...

Abstract

The invention discloses a flexible display module, a flexible display device and a manufacturing method of the flexible display module. The flexible display module comprises a bending area and a non-bending area, and further comprises a flexible display panel and a supporting layer arranged on the side, away from a light emitting side, of the flexible display panel, wherein the supporting layer comprises an extensible part corresponding to the bending area, the first surface, close to the flexible display panel, of the extensible part is provided with a first extensible structure, and the second surface, away from the flexible display panel, of the extensible part is provided with a second extensible structure. According to the flexible display module provided by the invention, the stretchable first extensible structure and the stretchable second extensible structure are respectively arranged on the two opposite surfaces of the supporting layer corresponding to the bending area, so that when the supporting layer supports the flexible display panel, adaptive stretching can be achieved through the first extensible structure and the second extensible structure according to the direction and the size of received bending stress, and the problem of folding marks caused by stress concentration of a bending area can be avoided.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display module, a flexible display device and a manufacturing method. Background technique [0002] Folding screens are currently being pursued more and more all over the world in the display field. The flexible display module of the conventional folding screen is provided with a supporting member as the supporting base of the module, and the supporting member is mostly a flat metal material. However, the metal material itself is difficult to bend, and stress concentration problems often occur during bending, which causes creases in the bending area of ​​the supporting member, and also causes creases in other laminates of the flexible display module. Furthermore, a display device made of the flexible display module may also have poor display in the bending area, which reduces user experience. Summary of the invention [0003] In order to solve at least one of the ...
