Claim 0:
1. A backplate for a display device, the display device comprising a bending region, and the backplate comprising: a supporting region, a bonding region disposed adjacent to the supporting region and configured to bond to the bending region of the display device, and the bonding region comprising: cutouts that are grooves;
wherein when the bending region and the bonding region are bent, squeezing stress is applied to the bending region receives, and the cutouts contract inwardly to reduce the squeezing stress applied to the bending region;
wherein a depth of one of the cutouts of the bonding region near the support region is greater than a depth of another of the cutouts of the bonding region away from the support region;
wherein the cutouts are divided into two cutout sets arranged symmetrically relative to the support region, each of the cutout sets has some of the cutouts, and the depths of the cutouts in each of the cutout sets gradually decrease from a side of the cutout set adjacent to the support region to another side of the cutout set away from the support region.
