Abstract
A folding display device includes a display panel and a support plate configured to support the display panel. The display panel includes a flexible display area. A bending area corresponding to the flexible display area is provided on the support plate, and an extensible hollow structure is provided in the bending area. By providing the hollow structure, deformability and extensibility of the bending area are improved, and a risk of peeling or cracking between layers of the display device is reduced.
Claims14
A folding display device, comprising:
- a display panel comprising at least one flexible display area;
- a support plate disposed below the display panel and configured to support the display panel, wherein the support plate comprises at least one bending area and a non-bending area, wherein the at least one bending area is corresponding to the flexible display area, and the bending area has an extensible hollow structure;
- and
- a back frame assembly arranged under the support plate, wherein the back frame assembly comprises at least one folding shaft and two back plates connected to both sides of the folding shaft, and the folding shaft is disposed corresponding to the bending area;
- 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 extensible hollow structure comprises a solid part and a hollow part, and the solid part is connected to the non-bending area;
- wherein the solid part is a network structure, and void enclosed by the solid part constitutes the hollow part;
- wherein the solid part has the same geometrical shape as a plurality of strip-shaped solid bodies interwoven and connected with each other, 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.
