    Abstract: Electronic devices may be provided with display structures such as glass and polymer layers in a liquid crystal display. The glass layers may serve as substrates for components such as a color filter layer and thin-film transistor layer. The polymer layers may include films such as a polarizer film and other optical films. During fabrication of a display, the polymer layers and glass layers may be laminated to one another. Portions of the polymer layers may extend past the edges of the glass layers. Laser cutting techniques may be used to trim away excess portions of the polymer layer that do not overlap underlying portions of the glass layers. Laser cutting may involve application of an adjustable infrared laser beam.

    Abstract: A system may include one or more electronic devices. Fiber bundles may be provided to convey light. A fiber bundle may have a bend along its length. Fibers for the fiber bundle may be formed from polymer cores coated with polymer claddings. The fibers may have end faces coated with antireflection coatings. The antireflection coatings may be formed from amorphous fluoropolymer deposited from solution. The fluoropolymer may be applied to the end faces of the fibers by dipping, spraying, or by dispensing with a needle dispenser or other dispensing tool. An optical component such as a light-emitting device for a communications system, an illumination system, or a sensor system may provide infrared light that is guided through the fiber bundle.

    Abstract: A light pipe such as a fiber ribbon may be formed from fibers joined by binder such as extruded binder. The fiber ribbon or other light pipe may have bends. A light source may provide light to an input of a fiber ribbon that is guided by the fiber ribbon to a corresponding output. The output may be located in an interior portion of an electronic device or may be positioned so that light from the output exits the electronic device and illuminates external objects. The light source may have light-emitting devices on a substrate. The light-emitting devices may be vertical cavity surface-emitting laser diodes or other lasers and/or may be light-emitting diodes. Light-emitting devices may be arranged in discrete clusters corresponding to the locations of fiber cores in the fiber ribbon.

    Abstract: An electronic device may be provided with a display having substrate layers such as a color filter layer, thin-film transistor layer, or other display layers. An array of pixels may be formed from thin-film circuitry on a display layer. A color filter layer may be formed from an array of color filter elements on a display layer. The color filter elements may provide the array of pixels with the ability to display color images. In a liquid crystal display configuration, a liquid crystal layer may be interposed between the substrate layers. A ring of sealant may surround the liquid crystal layer and may be interposed between the substrate layers. The display may have a periphery. The substrate layers may be welded with a glass weld such as a laser glass weld or other weld on an edge surface of the substrate layers running along the periphery.

    Abstract: An electronic device configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. A support structure is positioned below the surface, and one or more haptic actuators are coupled to the support structure. In some examples, the support structure is shaped or configured to amplify a response to a haptic actuator. When a haptic actuator is actuated, the support structure deflects, which causes the surface to bend or deflect at a location that substantially corresponds to the location of the activated haptic actuator. In some examples, prior to providing haptic feedback, at least one haptic actuator is electrically pre-stressed to place the haptic actuator(s) in a pre-stressed state. When haptic feedback is to be provided, at least one haptic actuator transitions from the pre-stressed state to a haptic output state to produce one or more deflections in the surface. In other examples, a haptic structure incorporates a piezoelectric element that is shaped to reduce the overall cost of the haptic structure while still providing high actuation performance.
