Embodiment 1

[0082] The foldable support includes a metal layer, the metal layer has a bending area, the part of the metal layer located in the bending area has a plurality of depressions penetrating through the metal layer, air is contained in the depressions, and the side walls of the depressions are in contact with the metal layer The angle between the planes is 45 degrees (refer to image 3 ).

[0083] When attaching to the flexible display panel, the side of the foldable support with a smaller cross-sectional area of ​​the recessed part is arranged close to the flexible display panel.

Embodiment 2

[0085] The foldable support includes a metal layer, the metal layer has a bending area, the part of the metal layer located in the bending area has a plurality of depressions, the depth of the depressions is half the thickness of the metal layer, air is in the depressions, and the depressions The angle between the side wall of the part and the plane where the metal layer is located is 45 degrees (refer to figure 1 ).

[0086] When being attached to the flexible display panel, the side of the foldable support member not provided with the recessed portion is arranged close to the flexible display panel.

Embodiment 3

[0088] The foldable support includes a metal layer, the metal layer has a bending area, the part of the metal layer located in the bending area has a plurality of depressions penetrating through the metal layer, the side wall of the depression has a protruding structure, and the protruding structure is Axisymmetric, and there is air in the depression, the angle between a part of the side wall of the depression and the plane where the metal layer is located is 45 degrees, and the angle between the other part and the plane where the metal layer is located is 135 degrees (refer to Figure 6 ).

[0089] When attaching to the flexible display panel, one side of the foldable support member (such as the side where the angle between the side wall of the recessed part and the plane where the metal layer is located is 45 degrees) is arranged close to the flexible display panel.

Abstract

The invention discloses a foldable supporting piece and a preparation method and a display device. The foldable supporting piece comprises a metal layer, wherein the metal layer comprises a non-bending region and at least one bending region; the part, located in the bending region, of the metal layer has a plurality of concave parts; and at least one sidewall of the concave parts are not perpendicular to the plane where the metal layer is located. Therefore, the foldable supporting piece can provide a high plane support function for a flexible display panel, in particular to provide high support for the bending region of the flexible display panel, and the overall anti-extrusion capability of the flexible display panel is improved; and meanwhile, the bending performance of the foldable supporting part and the performance of flatness recovery after bending are effectively improved, the problem of peeling of the flexible display panel and the foldable supporting piece can be effectivelyimproved, and the problem of creasing of the foldable supporting piece can be solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a foldable support, a preparation method, and a display device. Background technique [0002] With the diversification of flexible display products, folding display products are popular among users due to their advantages of portability and large size. Folding display products are based on flexible materials, which can make folding display products achieve bending effects. Since the flexible substrate is prone to poor appearance such as creep and irregular curling in a high-temperature environment, it affects the realization of folding display and also affects the normal display of display products. Therefore, currently, a foldable support member is usually provided on the back of the flexible display panel to support the flexible display panel. [0003] However, current foldable supports still need to be improved. Contents of the invention [0004] At present, the ...
