    Abstract: An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. To facilitate bending about the bend axis without damage, the display may include a display cover layer with a flexible portion. The flexible portion of the display cover layer may be interposed between first and second rigid portions of the display cover layer. The display cover layer may also include a layer with self-healing properties. The layer of self-healing material may be formed across the entire display cover layer or may be formed only in the flexible region of the display cover layer. The display cover layer may include a layer of elastomer in the flexible region of the display cover layer for increased flexibility. Self-healing may be initiated or expedited by externally applied heat, light, electric current, or other type of external stimulus.

    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.

    IPC: H01L33/48

    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.

    Abstract: An electronic device may be provided with a display mounted in a housing. The display is flexible and bends around a bend axis as the housing is folded and unfolded. When the housing is in an unfolded configuration, the display lies flat in a plane and displays images for a user. When the housing is folded along the bend axis and placed into a folded configuration, a first portion of the display is covered by the housing and is hidden from view, whereas a protruding second portion of the display is uncovered by the housing and exposed for viewing. Control circuitry in the device may display notifications, icons, and other content on the exposed second portion.

    Abstract: An electronic device may have control circuitry coupled to input-output devices such as a display. A flexible input-output device may be formed from an elastomeric substrate layer. The substrate layer may have signal paths to which components are mounted. Openings may be formed in the elastomeric substrate layer between the signal paths to create a stretchable mesh-shaped substrate. The electrical components may each include an interposer having solder pads soldered to the elastomeric substrate. Electrical devices such as micro-light-emitting diodes may be soldered to the interposers. The electrical components may also include electrical devices such as sensors and actuators. A stretchable lighting unit may have a stretchable light guide illuminated by a stretchable light source.
