Mobile terminal, screen control method, screen control device and storage medium

1. A mobile terminal, comprising:

a body including a front surface and a back surface;

a display screen including a first display region, a second display region, and a third display region connected sequentially, wherein the first display region is disposed on the front surface of the body, and the second display region is made of a flexible material; and

a first driving component disposed on the body and connected with a first slider through a first telescopic part;

wherein,

in a process that a state of the third display region is changed from an inward contraction state to an outward expansion state, the first driving component drives the first telescopic part to push the first slider outward, so the third display region is turned from the back surface of the body to the front surface of the body; and

in a process that the state of the third display region is changed from the outward expansion state to the inward contraction state, the first driving component drives the first telescopic part to pull the first slider inward, so that the third display region is folded from the front surface of the body to the back surface of the body.

2. The mobile terminal of claim 1 , wherein a bendable support part is provided under a back surface of the second display region.

3. The mobile terminal of claim 2 , wherein the bendable support part is one of silicone gel, thermoplastic polyurethanes (TPU) rubber, or a hinge.

4. The mobile terminal of claim 1 , wherein when the third display region is in the inward contraction state, a back surface of the third display region closely contacts with a first region on the back surface of the body.

5. The mobile terminal of claim 4 , wherein,

a first connection portion is disposed on the first region on the back surface of the body;

a second connection portion matched with the first connection portion is disposed on the back surface of the third display region; and

when the third display region is in the inward contraction state, a connection between the first connection portion and the second connection portion is formed.

6. The mobile terminal of claim 5 , wherein:

one of a snap connection or a magnetic connection is formed between the first connection portion and the second connection portion.

7. The mobile terminal of claim 4 , wherein the first region on the back surface of the body is provided with a camera.

8. The mobile terminal of claim 1 , wherein when the third display region is in the outward expansion state, an upper surface of the first slider is attached to a back surface of the second display region.

9. The mobile terminal of claim 1 , wherein a sliding groove is formed on an upper surface of the first slider, and a sliding part matched with the sliding groove is formed on a back surface of the first display region.

10. The mobile terminal of claim 1 , further comprising a limiting mechanism;

wherein the limiting mechanism limits a maximum displacement of the first slider in the process that the state of the third display region is changed from the inward contraction state to the outward expansion state.

11. The mobile terminal of claim 1 , wherein,

the display screen further comprises a fourth display region and a fifth display region, wherein the first display region, the fourth display region, and the fifth display region are sequentially connected, and the fourth display region and the second display region are respectively located on first and second sides of the first display region, and the fourth display region is made of the flexible material;

the mobile terminal further comprises a second driving component disposed on the body and connected with a second slider through a second telescopic part;

wherein,

in a process that a state of the fifth display region is changed from the inward contraction state to the outward expansion state, the second driving component drives the second telescopic part to push the second slider outward, so that the fifth display region is turned from the back surface of the body to the front surface of the body; and

in the process that the state of the fifth display region is changed from the outward expansion state to the inward contraction state, the second driving component drives the second telescopic part to pull the second slider inward, so that the fifth display region is folded from the front surface of the body to the back surface of the body.

12. A screen control method, applied to the mobile terminal of claim 1 , comprising:

receiving a screen expansion instruction; and

controlling the first driving component according to the screen expansion instruction, to drive the first telescopic part to push the first slider outward, so that the third display region is turned from the back surface of the body to the front surface of the body.

13. The method of claim 12 , further comprising:

receiving a screen contraction instruction; and

controlling the first driving component according to the screen contraction instruction, to drive the first telescopic part to pull the first slider inward, so that the third display region is folded from the front surface of the body to the back surface of the body.

14. A screen control device, applied to the mobile terminal of claim 1 , comprising:

a processor; and

a memory storing instructions executable by the processor;

wherein the processor is configured to:

receive a screen expansion instruction; and

control the first driving component according to the screen expansion instruction, to drive the first telescopic part to push the first slider outward, so that the third display region is turned from the back surface of the body to the front surface of the body.

15. The device of claim 14 , wherein the processor is further configured to:

receive a screen contraction instruction; and

control the first driving component according to the screen contraction instruction, to drive the first telescopic part to pull the first slider inward, so that the third display region is folded from the front surface of the body to the back surface of the body.
