    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.

    Abstract: In some aspects, mobile devices with foldable and rollable displays can use a sensor to detect vertical acceleration with respect to the ground to determine if the mobile device has been dropped. If the sensor detects that the mobile device has been dropped the foldable device can fold or retract at least partially to afford protection from the fragile display from striking the ground. Even folding the display to an angle less than 180 degrees can afford some protection because the mobile device can strike edges of the mobile device instead of the display itself. In various embodiments, a rollable device can retract the display if predetermined acceleration limits are exceeded.

    Abstract: A foldable electronic device may bend about a bend axis. A foldable display panel may be configured to bend along the bend axis as the foldable device is folded. A display cover layer may overlap the display panel. The display panel may have an array of pixels configured to display an image viewable through the display cover layer. The display cover layer may be formed from a layer of glass. A recess may be formed in the layer of glass that runs parallel to the bend axis and that overlaps the bend axis. The recess forms a flexible locally thinned portion in the glass that allows the display cover layer to bend. A rough surface texture and polymer coating may be provided in the recess. The recess may have shallowly sloping walls.
