Problems solved by technology

[0003] The flexible display device includes a flexible display screen and a supporting layer for supporting the flexible display screen. For a flexible display device with a rolled shape, the flexible display device usually needs to be wound more than three times. After winding, the flexible display screen is different. The stress distribution at the position is uneven, so there may be cases of screen damage caused by stress concentration in some areas

Abstract

The embodiment of the invention provides a supporting structure for supporting a flexible display screen and a flexible display device, and relates to the technical field of display. When the flexible display device is curled, uniform distribution of stress of the flexible display screen is guaranteed, meanwhile, a supporting layer is prevented from being broken, and the flatness of the flexible display screen is improved. The supporting structure comprises a flexible supporting layer, and the flexible supporting layer comprises a first supporting layer and a second supporting layer; the first supporting layer comprises a first surface and a second surface which are oppositely arranged, and the first surface is the surface, facing the flexible display screen, in the first supporting layer; the second supporting layer is located on one side of the second surface of the first supporting layer, the second supporting layer comprises a plurality of supporting parts arranged at intervals, the supporting parts comprise the first supporting parts and the second supporting parts, and the direction, pointing to the second supporting parts, of the first supporting parts is the curling direction of the flexible display screen; and the film thickness of the first supporting part is larger than that of the second supporting part in the direction perpendicular to the plane where the first supporting layer is located.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a support structure for supporting a flexible display screen and a flexible display device. 【Background technique】 [0002] Flexible display technology is an important development direction of current display technology. Flexible display devices have the characteristics of bendability, ultra-thin, low power consumption and portability, and are widely used in various electronic products. [0003] The flexible display device includes a flexible display screen and a supporting layer for supporting the flexible display screen. For a flexible display device with a rolled shape, the flexible display device usually needs to be wound more than three times. After winding, the flexible display screen is different. The stress distribution at the position is not uniform, so there may be cases of screen damage caused by stress concentration in some areas. 【Content of invention】 [0004]...
