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

Embodiments of the present invention provide a support structure for supporting a flexible display and a flexible display device, which relate to the field of display technology. When the flexible display device is curled, while ensuring the uniform distribution of the stress of the flexible display, it not only prevents the support layer from breaking, Also improve the flatness of the flexible display. The support structure includes a flexible support layer, the flexible support layer includes a first support layer and a second support layer; the first support layer includes a first surface and a second surface oppositely arranged, and the first surface is the first surface of the first support layer facing the flexible display screen. The surface; the second support layer is located on one side of the second surface of the first support layer, the second support layer includes a plurality of support portions arranged at intervals, the support portion includes a first support portion and a second support portion, and the first support portion The direction pointing to the second supporting part is the rolling direction of the flexible display; in the direction perpendicular to the plane where the first supporting layer is located, the film thickness of the first supporting part is greater than that of the second supporting part.

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]...
