The second elastic member 32 may be a spring. Adjacent two folding supports 21 may be elastically connected by one or more second elastic members 32. In some embodiments, the connection 212 of the folding support 21 is elastically connected by the second elastic member 32. Alternatively, the second elastic member 32 may be disposed at an end of the connecting member 212 near the flexible display panel 1, may be disposed at an end of the connecting member 212 near the supporting member body 211, and may be disposed at a middle position of the connecting member 212, and in some embodiments, the second elastic member 32 is disposed at an end of the connecting member 212 near the flexible display panel 1.
In this embodiment, the bending control assembly 3 further includes a second control assembly, where the second control assembly includes a plurality of second elastic members 32, and the plurality of folding support members 21 are elastically connected by the second elastic members 32, and when the flexible display device is bent, the second elastic members 32 deform and expand by a corresponding distance to adapt to the bending of the bendable region by using the elastic performance of the second elastic members 32; in the flattening process of the flexible display device, the second elastic piece 32 recovers deformation, and under the action of deformation force, the cutting 311 can automatically and smoothly retract into the slot 210, so that the flattening efficiency and quality are improved.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
