Abstract

A display device including: a flexible display panel including two fixing portions and a bendable portion between the fixing portions; a supporting component including two supporting portions arranged on surfaces of the fixing portions to support the flexible display panel along a X direction; at least one rotating shaft located between the supporting portions and arranged to correspond to the bendable portion; at least one sliding component including a first sliding member and a second sliding member that are slidably connected in the X direction, the first sliding member is connected to one supporting portion, the second sliding member is rotatably connected to the rotating shaft; at least one driving component including a first magnetic member and a second magnetic member, a magnetic force between the first and second magnetic members drive the first sliding member to move away from the rotating shaft.

First claim

What is claimed is:

1. A display device, comprising:
a flexible display panel comprising two fixing portions adjacent to each other and a bendable portion located between the two fixing portions;
a supporting component comprising two supporting portions, wherein the two supporting portions are arranged on surfaces of the two fixing portions respectively to support the flexible display panel along a X direction and a first supporting block is arranged on a side of a supporting portion away from a fixing portion;
at least one rotating shaft located between the two supporting portions and arranged to correspond to the bendable portion;
at least one sliding component comprising a first sliding member and a second sliding member slidably connected in the X direction, wherein the first sliding member is connected to one of the supporting portions, and the second sliding member is rotatably connected to the rotating shaft;
at least one driving component comprising a first magnetic member and a second magnetic member, wherein a magnetic force between the first magnetic member and the second magnetic member provides a driving force for the first sliding member to move along a direction away from the at least one rotating shaft.

2. The display device of claim 1 , wherein the display device has a folded state and a flat state, and in the flat state, the magnetic force between the first magnetic member and the second magnetic member provides the driving force for the first sliding member to move along the direction away from the at least one rotating shaft.

3. The display device of claim 2 , wherein magnetic properties of the first magnetic member and the second magnetic member are the same, and in the flat state, a distance between the first magnetic member and the second magnetic member is less than or equal to a first distance threshold, and a magnetic repulsion force between the first magnetic member and the second magnetic member provides the driving force for the first sliding member to move along the direction away from the at least one rotating shaft.

4. The display device of claim 3 , wherein in the flat state, the second magnetic member is located on a side of the first magnetic member facing the at least one rotating shaft.

5. The display device of claim 2 , wherein magnetic properties of the first magnetic member and the second magnetic member are different, and in the flat state, a distance between the first magnetic member and the second magnetic member is within a preset distance, and a magnetic attraction force between the first magnetic member and the second magnetic member provides the driving force for the first sliding member to move along the direction away from the at least one rotating shaft.

6. The display device of claim 5 , wherein in the flat state, the second magnetic member is located on a side of the first magnetic member away from the at least one rotating shaft.

7. The display device of claim 2 , wherein the first supporting block corresponds to a side of the fixing portion close to the bendable portion.

8. The display device of claim 7 , wherein a first buckle block is arranged on the second sliding member, and in the flat state, the first buckle block and the first supporting block are stacked in a thickness direction of the display device.

9. The display device of claim 8 , wherein the supporting component further comprises a supporting plate arranged on a side of the supporting portion and the rotating shaft away from the flexible display panel, wherein a second supporting block is arranged on the supporting plate, and the second supporting block is separated from the first supporting block along the thickness direction.

10. The display device of claim 9 , wherein a second buckle block is further arranged on the second sliding member, and in the flat state, the second buckle block and the second supporting block are stacked in the thickness direction.

11. The display device of claim 10 , wherein:
a first clamping groove is formed on a surface of one of the first supporting block and the first buckle block, and in the flat state, the first supporting block is affixed to the first buckle block via the first clamping groove.

12. The display device of claim 10 , wherein a second clamping groove is formed in a surface of one of the second supporting block and the second buckle block, and in the flat state, the second supporting block is affixed to the second buckle block via the second clamping groove.

13. The display device of claim 1 , wherein the at least one sliding component comprises two or more sliding components, wherein the two or more sliding components are separate from each other along a Y direction perpendicular to the X direction.

14. The display device of claim 13 , wherein the two or more sliding components are arranged on both sides of the at least one rotating shaft.

15. The display device of claim 14 , wherein the at least one rotating shaft comprises two rotating shafts, the two rotating shafts are arranged side by side in the X direction, and the second sliding members are respectively connected to the rotating shafts.

16. The display device of claim 14 , wherein the at least one rotating shaft comprises only one rotating shaft, the second sliding members arranged on both sides of the rotating shaft are staggered along the Y direction, and the two or more second sliding members are respectively connected to different positions of the rotating shaft.

17. The display device of claim 13 , wherein the at least one driving component comprises two or more driving components, each of the two or more driving component and each of the two or more sliding component are arranged in a one-to-one correspondence.

18. The display device of claim 1 , wherein a protective layer is arranged between the flexible display panel and the supporting component, and the supporting portions are connected to the fixing portions via the protective layer.

19. A mobile terminal comprising the display device of claim 1 .
