Abstract: An electronic device such as a wearable electronic device may have a band. The band may form a stand-alone device or a strap for a wristwatch unit or other device. Electrical components may be mounted on flexible printed circuit substrates. A substrate may be encapsulated by elastomeric polymer material or other material forming the band. The elastomeric polymer material may form cavities that receive the electrical components. Components such as light-emitting diodes may be mounted to the flexible printed circuit substrates so that the light-emitting diodes are located in the cavities. Reflective sidewalls in the cavities may reflect light from the light-emitting diodes outwardly through a thinned portion of the band. Light-diffusing material in the cavities may be formed from clear polymer with light-scattering particles.

Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed in a display panel having a single substrate or an array of display panel tiles. The display panel has inwardly facing display panel contacts that mate with corresponding outwardly facing interconnect substrate contacts on an interconnect substrate. The interconnect substrate may have areas with compound curvature that are overlapped by the display panel. To enhance flexibility of the interconnect substrate, the interconnect substrate may have flexibility enhancement openings and/or may be formed from a material with a low elastic modulus such as silicone or other elastomeric material.

Abstract: An electronic device such as a voice-controlled speaker device may have a housing characterized by a vertical longitudinal axis. A flexible substrate such as a flexible mesh substrate with component support regions coupled by flexible segments may be wrapped around the housing and the vertical axis. The housing may have surface regions with compound curvature. The flexible substrate may conform to the regions with compound curvature. A fabric spacer layer may be interposed between the flexible substrate and the housing. Electrical components such as input-output devices may be mounted to the component support regions. A display may be formed from an array of light-emitting devices that are mounted on respective component support regions. Light from the light-emitting devices may pass through the fabric spacer layer toward the housing and back out away from the housing. An outer fabric layer may cover the mesh.

Abstract: Flexible touch sensor panels can be implemented on a strap of a wearable device. A flexible touch sensor panel can provide an additional touch sensitive surface for a user to activate functions on the wearable device without covering a touch screen of the wearable device. In some examples, the flexible touch sensor panels can include electrode connectors configured to electrically couple touch electrodes of the flexible touch sensor panel. In some examples, the electrode connectors can have a serpentine routing pattern configured to allow the touch electrodes to move closer together or farther apart while maintaining electrical coupling between the touch electrodes. In some examples, the touch electrodes can have gaps configured to allow light to pass through the gaps. In some examples, an LED panel can be formed below or one or more waveguide layers can be formed above the flexible touch sensor panel.

Abstract: An electronic device such as a voice-controlled speaker device may have a cylindrical shape with upper and lower ends that have surface regions of compound curvature. The electronic device may have a display formed form an array of light-emitting devices such as light-emitting diodes. To provide the display with desired curvature (such as compound curvature), the display may be thermoformed. A flexible substrate for the display may be attached to a separate thermoplastic substrate. During a thermoforming process, the display may be heated such that the thermoplastic substrate softens into a pliable state. The display may then be molded into a desired shape. The display is then cooled to harden the thermoplastic substrate and secure the flexible substrate and light-emitting diodes in the desired shape. The thermoformed display may be stacked with additional functional layers such as a thermoformed touch-sensitive layer and/or a thermoformed lens layer.
