Claim 0:
1. A supporting plate configured to support a flexible display panel, wherein the supporting plate has at least one bending region and non-bending regions located on two sides of the bending region, the bending region comprises two semi-bending regions bent symmetrically along a bending axis, wherein any of the semi-bending regions comprises:
an internal bending region located on an end away from the non-bending regions; and
an outer bending region located on an end close to the non-bending regions and having a bending direction opposite to the internal bending region;
wherein the semi-bending regions comprise a plurality of openings spaced apart, a distribution density of the openings in the internal bending region is a first distribution density, and a distribution density of the openings in the outer bending region is a second distribution density;
wherein the first distribution density is greater than the second distribution density; and
wherein the outer bending region comprises a first sub-externally bending region away from the non-bending regions and a second sub-externally bending region close to the non-bending regions, and the openings on the outer bending region are all located in the first sub-externally bending region, the first lengths of the openings of the semi-bending regions are gradually decreased from the internal bending region to the transition region and are gradually increased from the transition region to the first sub-externally bending region, a bending radius of curvature of the semi-bending regions is gradually increased from the internal bending region to the transition region and is gradually decreased from the transition region to the first sub-externally bending region.
