Supporting plate and folding display device

Abstract

The embodiment of the invention discloses a supporting plate and a folding display device. The supporting plate comprises at least one bending area and non-bending areas located on the two sides of the bending area; the bending area comprises two half-bending areas which are symmetrically bent along a bending axis; any half-bending area comprises an inner bending area and an outer bending area, wherein the inner bending area is located at one end far away from the non-bending area, the outer bending area is located at one end close to the non-bending area, and the bending direction of the outer bending area is opposite to that of the inner bending area; each half-bending area comprises a plurality of open pores which are distributed at intervals, the density of the open pores of the inner bending area is a first density, the density of the open pores of the outer bending area is a second density, and the first density is larger than the second density. According to the supporting plate and the folding display device provided by the embodiment of the invention, the risk of adhesive layer separation at the junction of the inner bending area and the outer bending area when the folding display device is bent can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a support plate and a folding display device. Background technique [0002] Foldable mobile phones are an important direction of mobile phone research and development at present. There are mainly two ways of folding mobile phones on the market: inward folding and outward folding. The inward folding method is favored by consumers because the screen is not easy to be damaged inside when it is bent. According to the final bending shape of the screen, the inner bending can be divided into wedge bending and water drop bending. The wedge-shaped mobile phone cannot be completely closed after folding, and there is a gap in the middle, while the water-drop-shaped folding mobile phone does not have this defect, and can be completely closed after folding, so the water-drop-shaped folding mobile phone is more popular among consumers. However, the drop-shaped folding mobile phone has an inn...
