Textured cover assemblies for electronic devices are disclosed. The textured cover assemblies may be placed over a display and may provide anti-glare and anti-reflection properties to the electronic device.

Textured cover assemblies for display applications

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.

Electronic device with camera status indicator

An electronic device includes a housing, a speaker, control circuitry, a plurality of light-emitting components configured to emit light through an upper housing wall or other housing structure. A lens diffuser layer having lenses overlapping respective light-emitting components, a textured diffuser layer formed from textured coatings on a substrate, and a volume diffuser layer having light-scattering structures in a polymer layer might be included to project light from the light-emitting components. A light-guiding portion of the lens diffuser layer may guide light to a circular peripheral edge to form an illuminated ring visible through the upper housing wall.

Electronic device with diffusively illuminated housing portions

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.
