    Abstract: An electronic device may have input-output devices such as buttons formed from capacitive touch sensor electrodes. A transparent layer may be provided with opaque masking structures having a symbol-shaped opening aligned with a capacitive touch sensor electrode for a button or other input device. The symbol-shaped opening may be adjacent to the electrode and may be illuminated with light from a lighting system. The lighting system may include a light guide plate. The light guide plate may have edges that are oriented at non-zero angle with respect to each other. Light-emitting diodes of different colors may emit light into the edges. The light may be extracted from the light guide plate using bumps in a light extraction region. Light may be collimated using ribs formed on an opposing side of the light guide plate.

    Abstract: A rigid flex printed circuit board (PCB), method of manufacture, and display system incorporating the same are described. In an embodiment, a rigid flex PCB includes a flexible area extending from an adjacent routing area that is thicker than the flexible area. A flexible inner core spans the flexible area and the adjacent routing area. Outer stack-up layers are on the flexible inner core in the adjacent routing area. A cavity is formed in the outer stack-up layers in the routing area and exposes the flexible inner core. In an embodiment, a display system including such a circuit board may include an electronic component mounted on the flexible inner core within the cavity, and a distal end of the flexible area is bonded to a display panel.

    Abstract: An electronic device housing may have upper and lower portions that are attached with a hinge. At least one portion of the housing may have a rear planar surface and peripheral sidewalls having edges. A display module may be mounted in the housing. The display module may have glass layers such as a color filter glass layer and a thin-film transistor substrate. The color filter glass layer may serve as the outermost glass layer in the display module. The edges of the display module may be aligned with the edges of the peripheral housing sidewalls to create the appearance of a borderless display for the electronic device. The display module may be provided with an opening that allows a camera or other electronic components to receive light. Traces may be provided on the underside of the thin-film transistor substrate to serve as signal paths for the electrical components.

    Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a backlight unit. The backlight unit may include an array of light-emitting diodes and a light reflector that helps reflect light from the light-emitting diodes through the pixel array. A color conversion layer may be used to convert light from the light-emitting diodes from blue light to white light. A microlens array layer formed over the color conversion layer may spread the light from the color conversion layer to homogenize the light. To ensure light is emitted from the backlight with a uniform color, the microlens array layer may have different transmittance portions. A central portion of the microlens array layer may transmit more light and reflect less light than an edge portion of the microlens array layer.

    Abstract: A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light through the display. Light-emitting diodes may emit light into the light guide. A reflector that is overlapped by the light guide may help reflect light upwards through an array of pixels. The backlight unit may have a chassis that receives the reflector, light guide, light-emitting diodes, and optical films such as diffusers and prism films. Optical and mechanical features in the backlight unit may enhance color and intensity uniformity for the backlight illumination and may help enhance durability.

    Abstract: A backlight unit may include a turning film that receives light from a light guide layer. The turning film may have a plurality of elongated protrusions that extend across the turning film. Each protrusion may have a concave surface. The concave surface may be a curved surface that curves inward towards the interior of the turning film. Light from the light guide layer may pass through the turning film and be reflected towards a viewer by the concave surfaces of the protrusions. In a liquid crystal display, the turning film may be interposed between the light guide layer and a lower polarizer. In certain embodiments, the turning film may be the only optical layer interposed between the light guide layer and the lower polarizer. In other embodiments, the turning layer and a diffuser layer may be the only optical layers interposed between the light guide layer and the lower polarizer.
