Abstract

The embodiment of the invention discloses a supporting plate and a display device. The supporting plate is characterized in that a plurality of through holes are formed in a first region (namely a bending region), and a plurality of first grooves which are distributed in a first surface of a supporting plate body at intervals and a plurality of second grooves which are distributed in a second surface of the supporting plate body at intervals are formed in the transition region; and a stress difference between the first region and the second region(the supporting region) can be reduced so that stress generated during bending is distributed more uniformly, the problem of stress concentration at the junction of the bending region and the supporting region in the prior art can be effectively solved, cracks are prevented from being generated at the joint of the bendingregion and the supporting region, and the supporting piece is effectively prevented from being broken. According to the scheme, the weight of the supporting plate can be reduced, the rigidity of the supporting plate is reduced, the bending capacity of the supporting plate is improved, and therefore the reliability of the supporting plate is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a support plate and a display device. Background technique [0002] The rise of folding display devices such as foldable mobile phones has enabled the rapid development of folding display technology. The foldable display device includes a flexible support plate and a foldable display panel, and the flexible support plate is used to support the foldable display panel to ensure the appearance of the foldable display device. [0003] Due to the through holes provided in the bending area of ​​the current flexible supporting plate, there is a risk of fracture of the flexible supporting plate at the boundary between the bending area and the supporting area due to stress concentration. Contents of the invention [0004] Embodiments of the present invention provide a support plate and a display device to solve the problem that the existing support plate is easy to break. [0005] A ...
