Abstract:
An electronic device may have a display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The backlight structures may include a light guide plate that distributes light across the display layers. A light source such as a light-emitting diode light source may be used to provide light to the light guide plate. In one suitable embodiment, a light guide structure having a bend may be coupled between the light source and the light guide plate and may be used to guide the light from the light source to the light guide plate via total internal reflection. In another suitable embodiment, the light-emitting diodes may be mounted on a flexible printed circuit that is curled into a spring element. The flexible printed circuit may be used to bias the light-emitting diodes against the edge of the light guide plate.
Abstract:
An electronic device may have a hollow display cover structure. The hollow display cover structure may be formed from a structure having an inner surface. The structure may be an elongated member having a longitudinal axis. A material such as sapphire, other crystalline materials, or other transparent materials may be used in forming the hollow display cover structure. A flexible display layer such as an organic light-emitting diode display layer or other flexible display structure may be wrapped around the longitudinal axis to cover the interior surface of the hollow display cover structure. The electronic device may have a touch sensor, accelerometer, gyroscope, and other sensors for gathering input such as user input. The electronic device may use one or more sensors to gather information on rotational motion of the device and can display content on the flexible display layer accordingly.
Abstract:
An electronic device may be provided with a housing in which display structures are mounted. Additional input-output devices such as a track pad may also be mounted in the housing. These input-output devices may include components such as touch sensors and force sensors for gathering input from a user. The display structures may include a display such as a flexible organic light-emitting diode display or a liquid crystal display that can present visual information to the user. To provide the user with tactile output, an output device such as a display or track pad may be provided with electroactive polymer structures, electromagnetic actuators, and other tactile output devices. The tactile output devices may provide protrusions, indentations, selectively stiffened and softened areas, and other tactile output for a user.
Abstract:
An electronic device may include a display. The display may be an organic light-emitting diode display. The organic light-emitting diode display may have a substrate layer, a layer of organic light-emitting diode structures, and a layer of sealant. Vias may be formed in the substrate layer by laser drilling. The vias may be filled with metal using electroplating or other metal deposition techniques. The vias may be connected to contacts on the rear surface of the display. Components such as flexible printed circuits, integrated circuits, connectors, and other circuitry may be mounted to the contacts on the rear surface of the display.
