Claim 13:
14. A folding display device, comprising:
a back frame assembly comprising at least one folding shaft and two back plates connected to both sides of the folding shaft;
a support plate disposed on the back frame assembly and comprising at least one bending area corresponding to the folding shaft, wherein the back frame assembly is arranged under the support plate, and the bending area has an extensible hollow structure;
a display panel disposed on the support plate and comprising at least one flexible display area, wherein the folding shaft and the bending area are both disposed corresponding to the flexible display area; and
a front frame assembly disposed above the display panel, wherein the front frame assembly comprises a first frame and a second frame, the first frame and the second frame are rotatably connected, and a connection between the first frame and the second frame corresponds to the bending area;
the extensible hollow structure comprising a solid part and a hollow part, wherein the solid part is connected to a non-bending area of the support plate, the solid part has the same geometrical shape as a plurality of strip-shaped solid bodies interwoven and connected with each other, and void enclosed by the solid part constitutes the hollow part;
wherein the bending area and the non-bending area are an integrated structure, the bending area and the non-bending area form a complete plane supporting the display panel;
wherein the solid part is a network structure, and the strip-shaped bodies are curved in shape;
wherein the hollow part comprises a plurality of first repeating units, and the first repeating units have arc-shaped edges;
wherein the first repeating unit comprises first arc-shaped edges and second arc-shaped edges connected to two adjacent first arc-shaped edges; and
wherein the first repeating unit comprises three of the first arc-shaped edges and three of the second arc-shaped edges connected to the first arc-shaped edges, the first arc-shaped edges form three ends of the first repeating unit, and the second arc-shaped edges form three sides of the first repeating unit.
