Abstract: The present disclosure relates to systems and methods to control brightness and color output in foldable displays (12). A foldable electronic display (12) may, when folded, include a first part (62) in a first plane and a second part (64) in a second plane different from the first plane. A brightness or color setting of the first part (62) may be controlled independently of a brightness or color setting of the second part (64). The first part (62) and the second part (64) may be foldable at a folding angle (270) with respect to one another. The processing circuitry may provide image data to the foldable electronic display (12) that varies based at least in part on the folding angle (270).

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.

Abstract: An item may have a flexible support structure and may include a flexible component. The flexible component may have electrical components mounted on component mounting regions in a flexible circuit substrate. The component mounting regions may be interconnected by serpentine interconnect paths or other flexible interconnect paths. The flexible circuit substrate and component mounting regions may extend along a longitudinal axis of the flexible component or may form a two-dimensional array. Two-dimensional mesh-shaped flexible circuit substrates may be used in forming displays. The mesh-shaped flexible circuit substrates may be auxetic substrates that widen when stretched (e.g., structures with a negative Poisson's ratio that become thicker perpendicular to applied force when stretched) and that therefore reduce image distortion. Temporary tethers may help hold flexible circuit substrates together until intentionally broken following assembly of a flexible component into the flexible support structure.

Abstract: A foldable display device may have housing portions coupled by a hinge. The hinge may have a series of interconnected links. The links may be formed from interdigitated fingers in a friction clutch. The fingers or other portions of the links may be provided with crescent-shaped slots that receive pins. During folding of the device, the pins may slide along the crescent-shaped slots, thereby ensuring that adjacent links rotate relative to each other about a rotation axis that lies outside of the hinge and within a flexible display panel. Links may also be formed from link members with curved mating bearing surfaces that slide relative to each other as adjacent links are rotated relative to each other. A housing rotation synchronization mechanism may be formed using a set of gears that extends between the first and second housing portions.
