Abstract

A flexible display screen electronic apparatus and a control system thereof are provided. The flexible display screen electronic apparatus includes: an apparatus body, and a flexible display screen and a second roller which are disposed on the apparatus body. The flexible display screen includes a first end and a second end opposite to the first end, the first end is disposed on the apparatus body, the second end is fixed on a second roller, and the flexible display screen is configured to be windable around the second roller; and display surface area between the second end and the first end is variable. The flexible display screen electronic apparatus can change the size of the display screen flexibly as required to meet different demands of users.

First claim

What is claimed is:

1. A flexible display screen electronic apparatus, comprising: an apparatus body, a flexible display screen, a first roller, a second roller, a first displacement sensor and a second displacement sensor,
wherein the apparatus body comprises an upper frame, a lower frame opposite to the upper frame, a first side frame, and a second side frame opposite to the first side frame in a first direction;
the flexible display screen comprises a first end and a second end opposite to the first end;
the first roller is mounted on the first side frame, and the second roller is detachably mounted on the second side frame;
the first end is fixed on the first roller, the second end is fixed on the second roller, and the flexible display screen is configured to be windable around the first roller and the second roller, and a display surface area between the second end and the first end is configured to be variable;
the first displacement sensor is disposed on an end of the first roller, the second displacement sensor is disposed on an end of the second roller, and both the end of the first roller and the end of the second roller are closer to the lower frame compared with the upper frame; and
the second side frame is provided at a side of the flexible display screen in a direction perpendicular to the flexible display screen electronic apparatus in a case that the second roller is detached from the second side frame.

2. The flexible display screen electronic apparatus of claim 1 , wherein the apparatus body is further provided with a length-adjusting switch configured to control a length-adjusting state of the flexible display screen.

3. The flexible display screen electronic apparatus of claim 1 , wherein the second roller is mounted on the apparatus body through at least one second fastening section which is configured to be able to stretch out/draw back, and the flexible display screen electronic apparatus further comprises a second switch configured to control a stretching out/drawing back state of the second fastening section; and
the second switch is disposed on a side of the second roller toward a display side of the flexible display screen.

4. The flexible display screen electronic apparatus of claim 1 , wherein two opposite ends of the second roller are respectively provided with one second fastening section which is configured to be able to stretch out/draw back, and stretching out/drawing back states of two second fastening sections which are configured to be able to stretch out/draw back are controlled by a same second switch.

5. The flexible display screen electronic apparatus of claim 1 , wherein the first roller is further provided with a first switch configured to control a rotation of the first roller; and
the first switch is disposed on a side of the first side frame away from the second side frame in the first direction.

6. The flexible display screen electronic apparatus of claim 1 , further comprising a supporting section provided on a back of the flexible display screen.

7. The flexible display screen electronic apparatus of claim 6 , wherein the supporting section comprises a supporting strip formed of a metal or a polymer material.

8. A control system for the flexible display screen electronic apparatus of claim 1 , comprising:
a first obtaining unit configured to obtain the display surface area of the flexible display screen;
a second obtaining unit configured to obtain image data;
a processing unit configured to process the image data obtained by the second obtaining unit according to the display surface area of the flexible display screen obtained by the first obtaining unit; and
a display unit configured to display an image according to a processed result of the processing unit.

9. The flexible display screen electronic apparatus of claim 1 , wherein
a minimum value of a length of a display region of the electronic apparatus along the first direction is equal to a distance between adjacent sides of the first side frame and the second side frame.

10. The flexible display screen electronic apparatus of claim 1 , wherein
the second roller is configured to be located at a side of the second side frame far away from the first side frame in a the case that the second roller is detached from the second side frame.

11. The flexible display screen electronic apparatus of claim 1 , wherein a distance between the second displacement sensor and the first side frame is configured to be variable.

12. The flexible display screen electronic apparatus of claim 5 , wherein the first roller is provided with a spring leaf and the first switch controls the rotation of the first roller through the spring leaf to implement spreading and winding of the flexible display screen.

13. A flexible display screen electronic apparatus, comprising:
an apparatus body, a flexible display screen, a first roller, a second roller, a first displacement sensor and a second displacement sensor,
wherein the apparatus body comprises an upper frame, a lower frame opposite to the upper frame, a first side frame, and a second side frame opposite to the first side frame in a first direction;
the upper frame at least comprises a first upper frame, which acts as a length-unadjustable frame, and a second upper frame, which acts as a length-unadjustable frame and can be at least partially accommodated by the first upper frame;
the flexible display screen comprises a first end and a second end opposite to the first end;
the first roller is mounted on the first side frame, and the second roller is detachably mounted on the second side frame;
the first end is fixed on the first roller, the second end is fixed on the second roller, and the flexible display screen is configured to be windable around the first roller and the second roller, and a display surface area between the second end and the first end is configured to be variable; and
the first displacement sensor is disposed on an end of the first roller, the second displacement sensor is disposed on an end of the second roller, and both the end of the first roller and the end of the second roller are closer to the lower frame compared with the upper frame.

14. The flexible display screen electronic apparatus of claim 13 , wherein
the lower frame at least comprises a first lower frame;
the first upper frame and the first lower frame are opposite to each other in a second direction, which is perpendicular to the first direction; and
a minimum size of a display region of the electronic apparatus along the second direction is equal to a distance between adjacent sides of the first upper frame and the second upper frame.

15. The flexible display screen electronic apparatus of claim 13 , wherein
a size of the first upper frame along the second direction is larger than a size of the second upper frame along a second direction, which is perpendicular to the first direction.
