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.

Abstract: A fabric-based item may include fabric such as woven fabric having insulating and conductive yarns or other strands of material. The conductive yarns may form signal paths. Electrical components can be embedded within pockets in the fabric. Each electrical component may have an electrical device such as a semiconductor die that is mounted on an interposer substrate. The electrical device may be a light-emitting diode, a sensor, an actuator, or other electrical device. The electrical device may have contacts that are soldered to contacts on the interposer. The interposer may have additional contacts that are soldered to the signal paths. The fabric may have portions that form transparent windows overlapping the electrical components or that have other desired attributes.

Abstract: An electronic device may have a flexible display such as an organic light-emitting diode display. A strain sensing resistor may be formed on a bent tail portion of the flexible display to gather strain measurements. Resistance measurement circuitry in a display driver integrated circuit may make resistance measurements on the strain sensing resistor and a temperature compensation resistor to measure strain. A crack detection line may be formed from an elongated pair of traces that are coupled at their ends to form a loop. The crack detection line may run along a peripheral edge of the flexible display. Crack detection circuitry may monitor the resistance of the crack detection line to detect cracks. The crack detection circuitry may include switches that adjust the length of the crack detection line and thereby allow resistances to be measured for different segments of the line.

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.

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 devices with flexible displays, multilayer adhesive stacks may be included. A multilayer adhesive may attach a flexible display panel to the display cover layer in an electronic device. Including multiple layers of adhesive in the adhesive stack (as opposed to a single layer) provides more degrees of freedom for the tuning and optimization of the properties of the adhesive stack. The multilayer adhesive stack therefore has better performance than if only a single layer of adhesive is used. The multilayer adhesive stack may include one or more layers of soft adhesive, hard adhesive, hard elastomer, hard polymer, and/or glass to optimize the mechanical and optical performance of the multilayer adhesive stack. Soft adhesive layers may be included to optimize lateral decoupling (e.g., during folding and unfolding) of the adhesive stack. Harder layers may be included to provide rigidity and prevent denting during impact events.

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.
