In addition, since a length difference is generated between the side surface of the flexible display 300 and the side surface of the housing assembly 400 during the switching process between the folded and unfolded states of the foldable electronic device 10, the length difference can be changed by the elastic connection of the flexible display 300.

The elastic tension between the second end 320 and the second support plate 220 is obtained by providing an elastic member 340 between the second end 320 of the flexible display 300 and the second support plate 220. In one embodiment, the elastic member 340 is a strip, and may be an elongated member made of steel, for example. Both ends of the elastic member 340 are connected to the second end 320, and the middle portion of the elastic member 340 is connected to the second support plate 220. For example, a fixing post 350 may be provided on the second support plate 220 for positioning the elastic member 340. Specifically, the middle of the elastic member 340 may be disposed on one side of the fixed column 350, and both ends of the elastic member 340 are connected to the second end 320 of the flexible display 300 and pull the elastic member 340 from the flexible display 300 toward the other side of the fixed column 350, so that the elastic member 340 is elastically deformed when the electronic device is switched between the folded state and the unfolded state. Meanwhile, the flexible display 300 is under tension, so that the flexible display 300 does not collapse or sag.
