Abstract: A foldable electronic device may have a foldable housing. The foldable housing may be configured to bend about a bend axis. First and second portions of the housing that rotate relative to each other may be coupled by a hinge that is aligned with the bend axis. A foldable display may be coupled to the foldable housing and may be configured to bend along the bend axis as the foldable housing is folded. The display may have an array of pixels supported by a metal layer. The pixels may be interposed between a display cover layer and the metal layer. The foldable housing may have a support layer. To help support the display for bending about the bend axis while preventing damage to the display when the display is contacted by an external object, a spring layer may be interposed between the metal layer and the support layer.

Abstract: An electronic device has a foldable display. First and second portions of an electronic device housing for the device may be joined using hinge structures. A flexible display may overlap the first housing portion, the hinge structures, and the second housing portion. A layer such as a layer of sheet metal may be used in supporting the display and may overlap the hinge structures. The hinge structures may include gear teeth, belts, and/or other movement synchronization structures. The hinge structures may include members that move relative to each other during bending. The moving members may include bars and links with opposing curved bearing surfaces. Stop surfaces may prevent excessive rotation of the bars and links with respect to each other. The links may rotate about pivot points that lie within the thickness of the display without the hinge structure living within the thickness of the display.
