The foldable electronic device further comprises folding means for carrying the flexible display screen, which generally consist of two housings and a rotating mechanism connected between the housings. The two shells are folded or unfolded relatively through deformation of the rotating mechanism, and the flexible display screen is driven to be folded or unfolded. In the folding or unfolding process of the traditional folding device, two or three shielding plates are usually arranged on the surface of the folding device, which is away from the flexible display screen, so as to shield internal parts of the folding device, and the appearance effect of the unfolded electronic equipment is ensured.
