In this embodiment, the boundary between the movable portion 250 and the first connecting portion 210 is determined by the boundary between the portion of the flexible display panel 200 that is freely bent and the portion of the flexible display panel that is not freely bent when the flexible display panel 200 is changed from the flat state to the folded state. The portion of the flexible display 200 that is freely bent refers to a portion that can be bent in a substantially arc-shaped curved surface during the folding process, and the portion that is not freely bent refers to a portion that is substantially planar during the folding process, or a portion that is substantially continuously bent in two or more planes. Optionally, the movable portion 250 is an area that is not acted by an external force during a process of changing the flexible display screen 200 from the flat state to the folded state, and the first connecting portion 210 and the second connecting portion 220 are areas that are acted by an external force during a process of changing the flexible display screen 200 from the flat state to the folded state. The two main bodies 130 are connected to the back 240 of the flexible display 200, and in this embodiment, the flexible display 200 is located inside the foldable device 100 to form a fold-in screen.
In this application, the movable portion 250 is a region where the flexible display 200 can freely move during the bending process. That is, during the bending process of the flexible display panel 200, the movable portion 250 is separated from the folding apparatus 100, so that the movable portion 250 can move freely. The movable portion 250 is connected to the two first connecting portions 210, the two first connecting portions 210 can be supported by the first supporting plate 110, and no movable region exists between the first connecting portion 210 and the second connecting portion 220, so that the occupation ratio of the movable portion 250 in the flexible display screen 200 is minimized, a larger portion of the flexible display screen 200 is effectively supported and stabilized in the bending process, and the service life of the flexible display screen 200 is prolonged. The end of the first connection portion 210 adjacent to the movable portion 250 is tangent to the end of the movable portion 250 adjacent to the first connection portion 210, so that the first connection portion 210 and the movable portion 250 can be smoothly bent in a transition manner, no fold is formed between the first connection portion 210 and the movable portion 2509, and the appearance performance of the electronic device 1000 is ensured.
