Problems solved by technology

[0003] Existing flexible display devices mostly use a single-roller curling method to accommodate the flexible display screen. If the bending radius is small or the diameter of the roller is small, the flexible display screen is prone to damage due to excessive local stress.
[0004] Therefore, the existing flexible display device has the technical problem that the flexible display screen is easily damaged when it is curled, and needs to be improved.

Abstract

The invention provides a flexible display device, which comprises a shell, a roller group, a supporting layer and a flexible display screen. The shell is cylinder-shaped, a containing cavity is formedinside the shell, and an opening is formed on the lateral side of the shell. The roller group is arranged inside the containing cavity, and comprises a first roller and a second roller and a connecting part for connecting the first roller and the second roller. The axis of the first roller and the second roller is parallel to the axis of the shell. The supporting layer winds the first roller andthe second roller, and the winding direction of the supporting layer on the first roller is opposite to the winding direction of the supporting layer on the second roller. The supporting layer extendsout of the shell from an opening. The flexible display screen is arranged on the supporting layer. The winding direction of the flexible display screen on the first roller is opposite to the windingdirection of the flexible display screen on the second roller. With the stress cancelled out, the stress failure risk of the flexible display screen is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display device. Background technique [0002] Flexible display screens have the advantages of good bending resistance and are increasingly favored by the market. [0003] Existing flexible display devices mostly use a single-roller curling method to accommodate the flexible display screen. If the bending radius is small or the diameter of the roller is small, the flexible display screen is prone to damage due to excessive local stress. [0004] Therefore, the existing flexible display device has the technical problem that the flexible display screen is easily damaged when it is rolled, which needs to be improved. Contents of the invention [0005] The invention provides a flexible display device to alleviate the technical problem that the flexible display screen in the existing flexible display device is easily damaged when it is rolled. [0006] In order ...
