Support structure for supporting flexible display screen, and flexible display screen module
A flexible screen support structure includes a first flexible board, a second flexible board, a side board, and a number of electromagnets. The second flexible board is arranged opposite to the first flexible board and defines a gap together with the first flexible board. The gap is filled with an electro-rheological fluid. The side board encloses outer peripheral sides of the first and second flexible boards and seals the gap. The electromagnets are secured to the first flexible board and located in the gap, each electromagnet has a support surface attached to the first flexible board and a side surface at an acute angle to the support surface, and the side surfaces of adjacent electromagnets are mutually attached by a magnetic force to cause the first flexible board to roll up. A flexible display screen module is also provided.
