Support structure for supporting flexible display screen, and flexible display screen module

A flexible display screen module, comprising:

• a flexible display screen;
• a first flexible board having a first outer surface and a first inner surface arranged oppositely, the flexible display screen being attached to the first outer surface;
• a second flexible board arranged opposite to the first flexible board and spaced apart from the first flexible board, the first inner surface being oriented towards the second flexible board;
• a side board enclosing outer peripheral sides of the first flexible board and the second flexible board to cooperatively define a cavity with the first flexible board and the second flexible board, the cavity being filled with an electro-rheological fluid;
• and
• a plurality of electromagnets secured to the first inner surface and located in the cavity, each electromagnet having a side surface, side surfaces of two adjacent electromagnets defining a clearance therebetween, and the side surfaces of two adjacent electromagnets being able to be attached to each other by a magnetic force to cause the first flexible board to roll up.

A flexible display screen module, comprising:

• a flexible display screen;
• a flexible board arranged opposite to the flexible display screen, the flexible board and the flexible display screen defining a gap therebetween, and the gap being filled with an electro-rheological fluid;
• a side board enclosing outer peripheral sides of the flexible display screen and the flexible board and sealing the gap;
• and
• a plurality of electromagnets secured to the flexible display screen and located in the gap, each electromagnet having a support surface attached to the flexible board and a side surface at an acute angle to the support surface, and side surfaces of adjacent electromagnets being able to be attached to each other by a magnetic force to cause the flexible board to roll up.
