The relative position of the moving end and the crimp shaft 20 may be changed. The winding shaft 20 may be rotated to wind the flexible display panel 10.
The support plate 30 can be rolled or unfolded, and at least part of the support plate is attached to the back surface B of the flexible display panel 10 when the flexible display panel 10 is in an unfolded state; the winding shaft 20 is rotatably coupled to the first end 310 of the support plate 30 to support the flexible display panel 10; the flexible display panel 10 is slidable with respect to the support plate 30. The support plate 30 is made of a crimpable material so as to be crimpable or unfoldable. The support plate 30 can maintain an unfolded flat state after being unfolded, thereby providing support for the flexible display panel 10. The flexible display panel 10 can slide on the support plate 30 so that the flexible display panel 10 and the support plate 30 can be separately rolled. That is, the support plate 30 may be curled after the flexible display panel 10 is curled. Thus, in the rolled state, the flexible display panel 10 does not need to be sandwiched between two layers of the support plates 30, and the light exit surface of the flexible display panel 10 does not need to contact the bottom surface of the support plates 30.
The unfolding method of the flexible display device comprises the following steps: the support plate 30 is firstly unfolded, then the user pulls the flexible display panel 10 to unfold the flexible display panel 10 on the support plate 30, and the back surface B of the unfolded flexible display panel 10 is attached to the support plate 30. The method for curling the flexible display device comprises the following steps: first, the winding shaft 20 rotates to wind the flexible display panel 10, and after the winding is completed, the supporting plate 30 is wound.

The second magnetic material includes, but is not limited to: iron, steel, nickel, cobalt or manganese, etc. The second electromagnet has magnetism when being electrified, and can attract the second magnetic material for fixing the movable end 120 of the flexible display panel 10; the second electromagnet loses its magnetic property when the power is turned off, and the second magnetic material at the movable end 120 of the flexible display panel 10 can be released.
The back surface of the flexible display panel 10 may be provided with one second magnetic material or a plurality of second magnetic materials at intervals. A second electromagnet or a plurality of second electromagnets may be disposed at intervals on the corresponding support plate 30. When the flexible display panel 10 is fully unfolded, the second magnetic material is located right above the second electromagnet. When the flexible display panel 10 is fully or partially unfolded, the second electromagnet is energized to attract and fix the second magnetic material, so that the flexible display panel 10 is attracted and fixed to the supporting plate 30 to keep the flexible display panel 10 flat. Specifically, in the process of flattening the flexible display panel 10, when the position of the flexible display panel 10 does not change any more within a certain time, the second electromagnet is powered on to attract and fix the second magnetic material. Or after the flexible display panel 10 is completely flattened, the second electromagnet is powered on to attract and fix the second magnetic material. When the flexible display panel 10 is to be rolled, the second electromagnet is de-energized to release the second magnetic material, so that the flexible display panel 10 can slide with respect to the support plate 30. Further, when the flexible display panel 10 is to be rolled, the magnetism of the second electromagnet may be turned down, so that the flexible display panel 10 may slide relative to the supporting plate 30 while being attracted by the supporting plate 30, so that it may be kept flat during the rolling process.
