That is, when the second housing 200 is in the deployed position, the extension portion 250 of the second housing 200 fills the hollow region 600 beside the first housing 100 such that the first housing 100 is adjacent to the second housing 200. The two combined segments 310 and flexure segments 320 of the flexible display screen 300 are collectively supported. Under the support of the first housing 100 and the body portion 240 of the second housing 200 and the extension portion 250, the deformation of the flexure portion 320 of the flexible display screen 300 can be prevented from occurring to improve the flexible display screen 300. The flatness of the display surface can prevent the deflection segment 320 from being concavely deformed when the user touches the flexible display screen 300 when the touch interface is used. In this way, the development quality and touch comfort of the flexible display 300 can be improved.

In addition, as shown in FIG. 4, when the second housing 200 is in the deployed position, the third magnetic film 730 is attracted to the second magnetic film 720 on the extension portion 250 to force the flexural deformation of the flexure segment 320 temporarily.
