Abstract

A flexible display device includes a display panel and a plurality of curving-restricting structures. The display panel has a display surface and a bottom surface opposite thereto. The display surface has a visible region and an outer region surrounding the visible region. The curving-restricting structures may be disposed on at least one of the outer region of the display surface and the bottom surface of the display panel. Each curving-restricting structure has a top surface and at least a slanted side wall. The top surfaces of adjacent curving-restricting structures are spaced with each other, and the slanted side walls of adjacent curving-restricting structures face each other. When the flexible display device are curved to a predetermined extent, adjacent curving-restricting structures may resist against with each other to prevent the display panel from being unduly curved to be damaged, and thus a use reliability of the flexible display device is improved.

Claims (22)

1. A flexible display device, comprising:

a display panel has a display surface and a bottom surface opposite thereto, the display surface has a visible region and an outer region surrounding thereto, the display panel comprises a plurality of driver chips disposed in the outer region; and

a plurality of first curving-restricting structures disposed in the outer region, wherein each first curving-restricting structure covering corresponding one of the driver chips has a first top surface and at least a first slanted side wall, the first top surface of the adjacent first curving-restricting structures are separated to each other and the first slanted side walls thereof face to each other.

2. The flexible display device as recited in claim 1 , wherein the first curving-restricting structures are tapers.

3. The flexible display device as recited in claim 2 , wherein the first curving-restricting structures are triangular tapers, cones or polygonal tapers.

4. The flexible display device as recited in claim 3 , wherein the first curving-restricting structures are trapezoid tapers.

5. The flexible display device as recited in claim 2 , wherein a plurality of cross areas of each first curving-restricting structures parallel the display surface are growing smaller fromward the display surface.

6. The flexible display device as recited in claim 1 , wherein the first curving-restricting structures are formed integrally.

7. The flexible display device as recited in claim 1 , further comprising a plurality of second curving-restricting structures respectively corresponding to one of the first curving-restricting structures and disposed on the bottom surface, each second curving-restricting structure has a second top surface and at least a second slanted side wall, the second top surface of the adjacent second curving-restricting structures are separated to each other and the second slanted side walls thereof face to each other.

8. The flexible display device as recited in claim 7 , wherein the second curving-restricting structures are tapers.

9. The flexible display device as recited in claim 8 , wherein the second curving-restricting structures are triangular tapers, cones or polygonal tapers.

10. The flexible display device as recited in claim 9 , wherein the second curving-restricting structures are trapezoid tapers.

11. The flexible display device as recited in claim 8 , wherein a plurality of cross areas of each second curving-restricting structures parallel the bottom surface are growing smaller fromward the bottom surface.

12. The flexible display device as recited in claim 7 , wherein the second curving-restricting structures are formed integrally.

13. A flexible display device, comprising:

a display panel has a display surface and a bottom surface opposite thereto, the display surface has a visible region and an outer region surrounding thereto, the display panel comprises a plurality of driver chips disposed in the outer region; and

a plurality of curving-restricting structures disposed on the bottom surface and corresponded to the driver chips one on one, wherein each curving-restricting structure has a top surface and at least a slanted side wall, the top surface of the adjacent curving-restricting structures are separated to each other and the slanted side walls thereof face to each other.

14. The flexible display device as recited in claim 13 , wherein the curving-restricting structures are tapers.

15. The flexible display device as recited in claim 14 , wherein the curving-restricting structures are triangular tapers, cones or polygonal tapers.

16. The flexible display device as recited in claim 15 , wherein the curving-restricting structures are trapezoid tapers.

17. The flexible display device as recited in claim 14 , wherein a plurality of cross areas of each curving-restricting structures parallel the bottom surface are growing smaller fromward the bottom surface.

18. The flexible display device as recited in claim 13 , wherein the curving-restricting structures are formed integrally.
