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: A force-sensitive device for electronic device. The force inputs may be detected by measuring changes in capacitance, as measured by surface flex of a device having a flexible touchable surface, causing flex at a compressible gap within the device. A capacitive sensor responsive to changes in distance across the compressible gap. The sensor can be positioned above or below, or within, a display element, and above or below, or within, a backlight unit. The device can respond to bending, twisting, or other deformation, to adjust those zero force measurements. The device can use measure of surface flux that appear at positions on the surface not directly the subject of applied force, such as when the user presses on a part of the frame or a surface without capacitive sensors.

Abstract: An electronic device may have a housing with portions that slide relative to each other. A display may be supported on a surface of the housing such as on a front face of the housing. The housing portions may slide between an unexpanded state in which the display has an unexpanded viewable area on the front face and an expanded state in which the display has an expanded viewable area on the front face that is greater than the unexpanded viewable area. The housing portions may have interior regions that contain electrical components. The display may be formed from a flexible display substrate. A portion of a flexible display may be stored in an interior region of the housing when the housing is in the unexpanded state. In the unexpanded state, the flexible display may have one or more bends and may double back on itself one or more times.

Abstract: An electronic device housing may include a display cover layer that overlaps an array of pixels. The cover layer or other portion of the housing may have an opening that forms an optical and audio port. Optical and audio components may be coupled to the port. A port cover may cover some or all of the port. The port cover may include one or more layers of mesh or other materials that allow light and sound to pass while blocking environmental contaminants. The optical components may include an ambient light sensor or other devices that receive light and/or may include devices that emit light. The audio components may include a microphone and/or a speaker. The optical component may emit or receive light that passes through the audio component. A structure in the interior of the housing may form a passageway coupled to the port through which sound and light passes.
