[0050] With the development of the electronic industry, the demand for various super-large size display devices is increasing day by day, and the application in various scenes (such as large scenes such as studios, stages, conference rooms, hospitals and shopping malls) is also becoming more and more widespread. Therefore, spliced display devices are also paid more and more attention. The spliced display device can splice multiple display screens to form a super-large size spliced screen according to actual display needs to display a picture, and has the advantages of clear picture display, flexibility and the like.

[0051] However, in a super-large size splicing project, since the number of combined single screens is large, the cover plate area above the fan-out area in the display module is prone to being squeezed during assembly. Since the cover plate in this area has no support protection and is not stiff enough, the impact and squeezing resistance of this area is weak, and after being squeezed and deformed, display abnormalities will occur. Therefore, how to improve the impact resistance of the cover plate in the display module has become a problem to be solved at present.

[0052] Therefore, the present embodiment provides a flexible display module, and FIG. 1 shows a cross-sectional structure schematic diagram of a flexible display module according to an embodiment of the present disclosure.
