It should be noted that the folding manner of the electronic device 20 is not limited to the horizontal folding manner and the vertical folding manner, and may be any other folding manner with any angle.

As shown in fig. 1, the electronic device 20 may further include a foldable Display screen such as a foldable Display screen 400, and the foldable Display screen 400 may be a flexible OLED (Organic Light Emitting Diode) Display screen, a flexible Liquid Crystal Display (LCD), or other types of foldable Display screens. The foldable display 400 is used to display a picture. Foldable display screen 400 may be a regular shape, such as a rectangular parallelepiped, a rounded rectangle, or foldable display screen 400 may be an irregular shape.

When the first housing 210 and the second housing 220 are in the closed state, the foldable display 400 may be outside the first housing 210 and the second housing 220, or may be hidden inside the first housing 210 and the second housing 220.

In some embodiments, the electronic device 20 may include two foldable display screens, one foldable display screen 400 is disposed on one side of the first housing and the second housing, and the other foldable display screen 400 is disposed on the other side of the first housing and the second housing, that is, two foldable display screens are disposed on two opposite sides of the electronic device, and the two foldable display screens are disposed opposite to each other, in which case the electronic device may be a bi-directional foldable electronic device.
