Abstract

The invention discloses a foldable flexible display device. The display device includes a flexible display screen, a deformation layer and a memory layer; the deformation layer is arranged on the surface of one side of the flexible display screen and includes a plurality of gear components, each gear component includes a first end, a second end and a side face, the first end faces the display screen, the second ends faces the memory layer, the side face is connected between the first end and the second end, and the first end of each gear component is fixed with the display screen; the memory layer is arranged on the side, away from the display screen, of the deformation layer and made from shape memory materials and can elongate or shorten according to voltage applied on the memory layer. By means of the device, the influence of length change of the film layers on the device when the device is bent can be reduced, and bulging does not occur.

Description

technical field [0001] The present invention relates to the technical field of flexible displays, and more particularly, to a foldable flexible display device. Background technique [0002] Existing foldable flexible display devices include flexible display screens, protective films, and supporting structures, among which, flexible display screens are usually divided into foldable areas and non-foldable areas, and a rigid support is usually provided in the non-foldable area of ​​the flexible display screen. However, there is no rigid support structure in the foldable area, which can be bent at will, so as to realize the foldability of the flexible display device. [0003] For a foldable flexible display device, when it is bent from a flat state to a folded state, or when unfolded from a folded state to a flat state, the film layer of the foldable flexible display device on the side of the concave side of the neutral plane is subject to compressive stress, which is located at...
