Claim of US Patent No. 10,893,622

1. A cover plate for a flexible display screen, wherein the cover plate comprises deformable regions and non-deformable regions spaced apart along a first direction, the deformable regions comprising memory metal connecting the non-deformable regions, a number of the non-deformable regions is not less than four; wherein, when the memory metal of the deformable regions is in a low temperature phase shape, the projections of the non-deformable regions at least partially overlaps in a direction perpendicular to the display screen; when the memory metal of the deformable regions is in a high temperature phase shape, the deformable regions and the non-deformable regions are on a same horizontal plane; wherein, the memory metal of the deformable regions comprising a diamond shape mesh structure, wherein at least one of the deformable regions is composed of two or more sub-deformation regions, and having gaps between the sub-deformation regions, wherein from the high temperature phase shape to the low temperature phase shape, the deformable regions bend 180 degrees clockwise or counter-clockwise, and each of the non-deformable regions is parallel with each other on a same direction.
