In the embodiment of the present application, the electromagnetic controller 510 (see fig. 8) controls the magnetism generating assembly 400 to control the magnetism generating assembly 400 to have magnetism or lose magnetism, so as to attract the supporting member 300, so that the supporting member 300 is attracted to the non-display surface of the flexible screen body 200, thereby achieving the effect of supporting the flexible screen body 200, and when the flexible screen body 200 is curled or wound, the supporting member 300 is separated from the non-display surface of the flexible screen body 200, so as to reduce the stress generated by the flexible screen body 200 when the flexible screen body 200 is curled or wound, thereby improving the service life of the flexible screen body 200. Specifically, in the embodiment of the present application, when the first board body 110 and the second board body 120 are far away from each other to the maximum distance or the maximum distance carried by the flexible screen body 200, the electromagnetic controller 510 automatically controls the magnetism generating assembly 400 to generate magnetism, so that the supporting member 300 is attracted to the non-display surface of the flexible screen body 200; or when the first board body 110 is far away from the second board body 120 and the maximum distance is not reached, the electromagnetic controller 510 may be manually activated by the user to control the magnetic force generating assembly 400 to be attracted to the non-display surface of the flexible screen body 200.

In the embodiment of the present application, the magnetism generating assembly 400 includes an electromagnetic shielding film 410 and a magnetic film 420, which are stacked, wherein the electromagnetic shielding film 410 is disposed between the magnetic film 420 and the non-display surface of the flexible screen body 200; the electromagnetic shielding film 410 is electrically connected to the electromagnetic controller 510, a path between the electromagnetic controller 510 and the electromagnetic shielding film 410 is disconnected when the first board body 110 is away from the rear electromagnetic controller 510 with respect to the second board body 120, and a path between the electromagnetic controller 510 and the electromagnetic shielding film 410 is connected when the first board body 110 is close to the rear electromagnetic controller 120 with respect to the second board body 120.
