Abstract

A support structure for supporting a flexible display screen includes: a plurality of electromagnets and a controller electrically coupled to the plurality of electromagnets. Each electromagnet has a first surface and a second surface. The first surface is configured to be attached and secured to a flexible display screen so as to support the flexible display screen, and the second surface is at an acute angle to the first surface. When the flexible display screen is extended, the controller controls two adjacent electromagnets to repel each other. When the flexible display screen is bent, the controller controls two adjacent electromagnets to attract each other.

First claim

What is claimed is:

a plurality of electromagnets, each electromagnet having a first surface and a second surface, the first surface being configured to be attached and secured to the flexible display screen so as to support the flexible display screen, and the second surface being at an acute angle to the first surface;
a controller electrically coupled with the plurality of electromagnets, when the support structure is expanded, the controller being configured to control second surfaces of two adjacent electromagnets to be mutually repelled; when the support structure is bent, the controller being configured to control second surfaces of two adjacent electromagnets to be mutually attracted;
a flexible panel, the plurality of electromagnets being secured to the flexible panel;
a flexible back board, the flexible back board being arranged opposite to the flexible panel and defining a gap together with the flexible panel, and the plurality of electromagnets being located in the gap; and
a side board, the side board enclosing outer peripheral sides of the flexible panel and the flexible back board, and the side board sealing the gap.

2. The support structure according to claim 1 , wherein the electromagnet is tapered.

3. The support structure according to claim 1 , wherein each electromagnet has a first magnetic pole and a second magnetic pole arranged side by side on the flexible display screen.

4. The support structure according to claim 3 , wherein the first magnetic pole and the second magnetic pole of each electromagnet are arranged side by side along a length direction of the flexible display screen.

5. The support structure according to claim 1 , wherein the flexible panel is configured to be attached to the flexible display screen.

6. The support structure according to claim 1 , wherein the plurality of electromagnets are arranged in an array on the flexible panel.

7. The support structure according to claim 1 , wherein the flexible panel is an elastic memory board.

8. The support structure according to claim 1 , wherein the side board is a flexible board.

9. The support structure according to claim 1 , wherein a clearance is defined between the flexible back board and the electromagnet, and the clearance forms an airflow channel.

10. The support structure according to claim 1 , wherein each electromagnet further has a third surface arranged opposite to the first surface, and the third surface is attached to the flexible back board.

11. A flexible display screen module, comprising:
a flexible display screen;
a flexible panel having an outer surface and an inner surface arranged oppositely, the flexible display screen being attached to the outer surface;
a plurality of electromagnets secured to the inner surface, each electromagnet having a side surface, side surfaces of two adjacent electromagnets defining a clearance therebetween;
a controller electrically coupled with the plurality of electromagnets, when the flexible display screen is expanded, the controller being configured to control side surfaces of two adjacent electromagnets to be mutually repelled; when the flexible display screen is bent, the controller being configured to control side surfaces of two adjacent electromagnets to be mutually attracted;
a flexible back board spaced apart from the flexible panel, the inner surface being oriented towards the flexible back board; and
a side board enclosing outer peripheral sides of the flexible panel and the flexible back board to cooperatively define a cavity with the flexible panel and the flexible back board, the plurality of electromagnets being located in the cavity.

12. The flexible display screen module according to claim 11 , wherein each electromagnet has a top surface configured to support the flexible display screen, the top surface is attached to the inner surface, and top surfaces of two adjacent electromagnets are closely coupled.

13. The flexible display screen module according to claim 12 , wherein the side surface is at an acute angle to the top surface for each electromagnet.

14. The flexible display screen module according to claim 12 , the flexible panel is a rectangular board, the flexible back board is a rectangular board, and the flexible back board has the same size as the flexible panel.

15. A flexible display screen module, comprising:
a flexible display screen;
a plurality of electromagnets secured to the flexible display screen, each electromagnet having a first magnetic pole and a second magnetic pole arranged side by side on the flexible display screen;
a controller electrically coupled with the plurality of electromagnets, when the flexible display screen is expanded, the controller being configured to control the first magnetic pole of one electromagnet to approach to the first magnetic pole of another adjacent electromagnet, or to control the second magnetic pole of one electromagnet to approach to the second magnetic pole of another adjacent electromagnet; when the flexible display screen is bent, the controller being configured to control the first magnetic pole of one electromagnet to approach to the second magnetic pole of another adjacent electromagnet, or to control the second magnetic pole of one electromagnet to approach the first magnetic pole of another adjacent electromagnet; and
a flexible back hoard and a side board, the flexible back board is arranged opposite to a flexible panel and defines a gap together with the flexible panel, and the plurality of electromagnets are located in the gap, and the side hoard encloses outer peripheral sides of the flexible panel and the flexible back board and seals the gap.

16. The flexible display screen module according to claim 15 , wherein the flexible display screen is an organic electroluminescent display layer.
