In the exemplary embodiment, the winding assembly 5 has the function of winding and storing, and can wind and store a part or all of the flexible display screen 3, such that the flexible display screen 3 is pulled out when the second housing 1 slides out of the first housing 2, and the flexible display screen 3 is stored when the second housing 1 slides into the first housing 2.

In an exemplary embodiment, the rigid support strip 401 at least has a first surface located at a side of the rigid support strip close to the rolling portion and fixedly connected with the rolling portion, such that the support structure 4 can be pulled out or stored by the winding assembly following the flexible display screen. When the support structure 4 includes at least two rigid support strips 401, the first surfaces of the adjacent rigid support strips forms a support surface 402 that provides a support force for the flexible display screen.

In an exemplary embodiment, the first surface is planar to provide uniform support force for the flexible display screen.

As shown in FIG. 5 and FIG. 6, a rigid support strip 401 also has a second surface located at a side of the rigid support strip 401 close to the second housing 1 and slidably connected with the outer surface of the second housing 1, such that the support structure can slide into or out of the first housing following the second housing.
