wherein the first telescopic bracket and the plurality of second telescopic brackets drive the flexible screen to form a curved surface;
wherein each of the second telescopic brackets comprises a first assembly plate;
wherein each first assembly plate comprises a first main assembly board and a first rotating board rotatably arranging on the first main assembly board, the first main assembly board couples one side of the support board.

2. The flexible screen support device of claim 1 , wherein the first telescopic bracket couples a first driving unit, and each of the plurality of second telescopic brackets couples a second driving unit; wherein the first driving unit and each of the second driving unit comprises a driving motor, a screw rod coupling the driving motor, and a driving block sleeving on the screw rod; wherein the screw rod drives the driving block to expand and retract the first telescopic bracket and the second telescopic bracket.

3. The flexible screen support device of claim 2 , wherein the first driving unit and each second driving unit are piston cylinders; the first driving unit of the first telescopic bracket comprises a pushing rod of the cylinder and a coupling block coupling the pushing rod, and the second driving unit of the second telescopic bracket comprises a pushing rod of the cylinder and a flexible movable block coupling the pushing rod; wherein the flexible screen is support by the coupling block and the flexible movable block.

4. The flexible screen support device of claim 1 , wherein each of the second telescopic brackets comprises a second assembly plate, a first support rod comprising a first end and a second end, and a second support rod comprising a third end and a fourth end; wherein the first end and the fourth end slidably arrange on the first assembly plate, and the second end and the third end slidably arrange on the second assembly plate; wherein the first support rod and the second support rod couple each other in a cross way and rotate relative to each other.

5. The flexible screen support device of claim 1 , wherein each of the second telescopic brackets comprises a second assembly plate, a first support rod comprising a first end and a second end, and a second support rod comprising a third end and a fourth end; wherein the first end slidably arrange on one end of the first assembly plate, the second end rotates around a second axis pivotally penetrating the other end of the second assembly plate, the third end slidably arrange on one end of the second assembly plate and the forth end rotates around a first axis pivotally penetrating the other end of the first assembly plate; the first support rod and the second support rod couple each other in a cross way and rotate relative to each other.

6. The flexible screen support device of claim 1 , wherein each of the second telescopic brackets comprises a second assembly plate, a first support rod comprising a first end and a second end and a second support rod comprising a third end and a fourth end;
wherein a first rotating shaft and a first pushing member arrange on the first assembly plate;
wherein the first pushing member rotatably sleeves on the first rotating shaft and slides along a length direction of the first rotating shaft; wherein the first pushing member couples a driving block of a first driving unit and the first end of the first support rod; wherein the first pushing member drives the first support rod to slide along a length direction of the first assembly plate.

7. The flexible screen support device of claim 6 , wherein the first main assembly board and the first rotating board rotatably arranges on the first main assembly board through the first rotating shaft;
wherein the first end and the fourth end couples the first rotating board; wherein the first end of the first support rod coupling the first pushing member slidably moves on the first rotating board along an axial direction of the first rotating shaft.

8. The flexible screen support device of claim 6 , wherein the first rotating shaft arranges on the first main assembly board, and comprises a first section and a second section; wherein the first pushing member sleeves on the first section of the first rotating shaft; wherein a limiting area is defined on the first rotating board and the first section locates therein.

9. The flexible screen support device of claim 8 , wherein a torsion spring arranges on the first main assembly board, locates on the second section of the first rotating shaft, and abuts against the first main assembly board and the first rotating board.

10. The flexible screen support device of claim 6 , wherein the second assembly plate comprises a main coupling plate and a second rotating board rotatably installing on the main coupling plate through a second rotating shaft; wherein the second end and the third end couple the second rotating board.

11. The flexible screen support device of claim 10 , wherein a first sliding slot is defined on one end of the first rotating board, and a second sliding slot is defined on one end of the second rotating board; wherein the first end slidably receives in the first sliding slot, and the third end slidably receives in the second sliding slot.

12. The flexible screen support device of claim 6 , wherein center portion of the first support rod and center portion of the second support rod couple together by a shaft.

13. The flexible screen support device of claim 6 , wherein the driving block of the first driving unit comprises a coupling end in arc shape and the first pushing member comprises a coupling slot in arc shape; wherein the coupling end inserts into the coupling slot, and the first pushing member drives the driving block of the first driving unit to rotate around the first rotating shaft.

14. The flexible screen support device of claim 1 , wherein the first telescopic bracket comprises a third assembly plate, a fourth assembly plate, a third support rod and a fourth support rod; wherein two ends of the third support rod slidably arranges on one end of the third assembly plate and one end of the fourth assembly plate, respectively, and two ends of the fourth support rod slidably arranges on other end of the third assembly plate and other end of the fourth assembly plate, respectively; wherein the third support rod and the fourth support rod couple each other in a cross way and rotate relative to each other.
