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 a printed circuit board, a plurality of light-emitting diodes mounted on the printed circuit board, at least one light spreading layer formed over the printed circuit board that spreads light received from the plurality of light-emitting diodes, a partially reflective layer formed over the at least one light spreading layer, a color conversion layer formed over the partially reflective layer, a collimating layer formed over the color conversion layer, a brightness enhancement film formed over the collimating layer, and a diffuser formed over the brightness enhancement film. The at least one light spreading layer may include two light spreading layers with elongated protrusions that are rotated relative to each other.

Abstract: An electronic device may have a camera. The camera may capture still and moving images. A camera status indicator may be included in the electronic device. The camera status indicator may emit light to indicate when the camera is in use capturing video or other images. The camera status indicator may have multiple light-emitting devices such as light-emitting diodes or lasers. The light-emitting devices may have different colors. Clear encapsulant may cover the light-emitting devices. A white polymer wall or other light recycling structure may run along an outer peripheral edge of the encapsulant. A light diffusing coating layer may coat an outer surface of the clear encapsulant. Light reflections from the status indicator may be reduced in captured images.

Abstract: An electronic device may have electrical components mounted in an interior region of the electronic device. A housing may surround the interior region and may separate the interior region from an exterior region that surrounds the electronic device. Arrays of recesses may be formed on opposing inner and outer sides of the housing. The arrays may be laterally offset from each other along the housing. The recesses on the inner and outer sides of the housing may meet at passageways within the housing. During operation of the electronic device, air may flow through the inner recesses, the passageways, and the outer recesses to cool electrical components within the interior region. Lighting may be provided for the housing. Light-emitting devices such as light-emitting diodes may be received within cavities in the housing. Light guiding structures, diffusers, reflectors, and other structures may be used to help adjust illumination from the light-emitting devices.

Abstract: Privacy control can be provided for displays that output content for users within an enclosed space. Display systems can include sensors that detect an external illuminance of an external environment outside the enclosed space. Based on the external illuminance and the brightness output by the display, the display system can control one or more of a variety of operating parameters to enhance privacy for the user within the enclosed space. For example, the display can be controlled with a reduced brightness when the external illuminance is low. By further example, windows separating the enclosed space from the external environment can be provided with an ability to adjust a transmissivity thereof and thereby reduce transmission of light from the display to the external environment. By further example, the display can be operated to change or omit certain content that has a relatively high privacy threshold.

Abstract: An electronic device may have a display with an array of pixels configured to display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. A set of the pixels may overlap the ambient light sensor so that ambient light measurements may be made on ambient light passing through the set of pixels. Control circuitry in the electronic device may control light transmission through the set of pixels so that different light transmission levels can be used in different ambient light conditions. Directional light measurements may be made by moving transparent pixels dynamically across the surface of the display overlapping the light sensor and/or by using pixelated light modulators to vary the angle of light rays measured by the ambient light sensor.

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 direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.
