Electronic device

1. An electronic device, comprising:

a body, comprising a first surface, a second surface, and a lateral surface, wherein the first surface and the second surface are opposite to each other, wherein the lateral surface is adjacent to the first surface and the second surface; and

a flexible display, comprising a first display portion and a second display portion that are integrated, wherein the flexible display is configured to move between a retracted state and a sliding-out state,

wherein, when the flexible display is in the retracted state, the first display portion covers the first surface and the lateral surface, and the second display portion is covers at least part of the second surface;

when the flexible display is moved from the retracted state to the sliding-out state, the first display portion slides along a direction where a free end thereof moves toward the lateral surface to expose a hidden region of the first surface;

wherein, when the flexible display is switched from the retracted state to the sliding-out state, the second display portion and the second surface are kept relatively static and

wherein the body comprises:

a main body, wherein the first surface and the second surface form the main body; and

a moving body, wherein the moving body is adjacent to the main body and has a lateral surface,

wherein, when the flexible display is in the retracted state, the moving body is adjacent to the main body; and when the flexible display is in the sliding-out state, the moving body is separated from the main body.

2. The electronic device of claim 1 , wherein a movement velocity of the moving body is matched with a sliding velocity of the first display portion to move the first display portion evenly with the moving body.

3. The electronic device of claim 1 , wherein the moving body has a cylindrical structure and the main body has a surface that is sunken inwards to form a cambered surface matched with the moving body, wherein the surface is facing the moving body.

4. The electronic device of claim 1 , wherein, when the flexible display is switched from the retracted state to the sliding-out state, the second display portion moves along a direction where a free end thereof is capable of moving away from the lateral surface.

5. The electronic device of claim 4 , wherein a movement distance of the first display portion is equal to a movement distance of the second display portion.

6. The electronic device of claim 1 , wherein a sliding direction of the flexible display is a length direction or width direction of the electronic device.

7. The electronic device of claim 1 , wherein at least one of following functional components is arranged in the hidden region: a camera, an ambient light sensor, a distance sensor, a dot matrix projector and a receiver.

8. The electronic device of claim 1 , further comprising:

a driving circuit, capable of driving the flexible display to move between the retracted state and the sliding-out state; and

a control circuit, coupled to the driving circuit to drive the driving circuit to move.

9. The electronic device of claim 1 , wherein a sliding direction of the flexible display is a length direction or width direction of the electronic device.

10. The electronic device of claim 1 , wherein a sliding direction of the flexible display is a length direction or width direction of the electronic device.

11. The electronic device of claim 2 , wherein a sliding direction of the flexible display is a length direction or width direction of the electronic device.

12. The electronic device of claim 3 , wherein a sliding direction of the flexible display is a length direction or width direction of the electronic device.

13. The electronic device of claim 1 , wherein at least one of following functional components is arranged in the hidden region: a camera, an ambient light sensor, a distance sensor, a dot matrix projector and a receiver.

14. The electronic device of claim 1 , wherein at least one of following functional components is arranged in the hidden region: a camera, an ambient light sensor, a distance sensor, a dot matrix projector and a receiver.

15. The electronic device of claim 2 , wherein at least one of following functional components is arranged in the hidden region: a camera, an ambient light sensor, a distance sensor, a dot matrix projector and a receiver.

16. The electronic device of claim 1 , further comprising:

a driving circuit, capable of driving the flexible display to switch between the retracted state and the sliding-out state; and

a control circuit, electrically connectable with the driving circuit to drive the driving circuit to move.

17. The electronic device of claim 1 , further comprising:

a driving circuit, capable of driving the flexible display to switch between the retracted state and the sliding-out state; and

a control circuit, electrically connectable with the driving circuit to drive the driving circuit to move.

18. The electronic device of claim 2 , further comprising:

a driving circuit, capable of driving the flexible display to move between the retracted state and the sliding-out state; and

a control circuit, coupled to the driving circuit to drive the driving circuit to move.
