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 illustrate the present invention more clearly, the present invention will be further described below with reference to the preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically 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" described herein may mean that one layer is directly formed or disposed on another layer, or may mean that a layer is formed directly on or disposed on another layer. A layer is formed or disposed indirectly on another layer, ie there are other layers in between. As used herein, unless otherwise specified, the term "on the same layer" means that two layers, parts, members, elements or sections may be formed by the same patterning process, and that the two...

Abstract

The invention discloses a flexible display module, a flexible display device and a manufacturing method. The flexible display module includes a bending area and a non-bending area; the flexible display module includes a flexible display panel and is disposed on a side of the flexible display panel away from the light output. The support layer on the side; the support layer includes an extensible part corresponding to the bending area, the extensible part is provided with a first extensible structure close to the first surface of the flexible display panel, and the extensible part is provided with a second surface away from the flexible display panel. Second malleable structure. In the flexible display module provided by the present invention, the first stretchable structure and the second stretchable structure are respectively provided on two opposite surfaces of the support layer corresponding to the bending area, so that the support layer can support the flexible display panel. At the same time, according to the direction and magnitude of the accepted bending stress, adaptive stretching can be achieved through the first extensible structure and the second extensible structure, which can avoid the crease problem caused by the stress concentration problem in the bending area. .

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] At present, folding screens are being pursued more and more by the world in the display field. The flexible display module of a conventional folding screen is provided with a support member as the support base of the module, and the support member is mostly a flat metal material. However, the metal material itself is difficult to bend, and during bending, stress concentration problems often occur, resulting in creases in the bending area of ​​the supporting components, and at the same time, other laminates of the flexible display module are prone to creases. Further, the display device made by using the flexible display module will also have poor display in the bending area, which reduces the user experience. SUMMARY OF THE INVENTION [0003] In order to sol...
