Abstract: A system for illuminating a reflective display or other material from a planar front device and a method of manufacture thereof. The system includes a light guide plate that conducts light from an edge light source across the face of a reflective display. Micro lenses are formed on the inner or outer surface of the light guide and direct the light conducted in the light guide toward the display. A stepped index layer is formed on the surface of light guide plate containing the micro lenses. The stepped index layer has an index of refraction lower than an index of refraction of the light guide plate to assist in the total internal reflection of light injected into the light guide plate. A top layer protective coat or touch screen can be laminated to the outside of the light guide plate.

Abstract: A computing device comprises a platform and an audio receiver component. The audio receiver component is provided on a front side of the platform and is oriented to emit sound out of the front of the housing. A gap volume adjacent to the audio receiver is defined by the front side of the platform and the front façade of the housing. The gap volume supports audio output from the audio receiver component. A first air channel is defined by a combination of (i) a through-hole in the platform at the gap volume, and (ii) an opening in a back façade of the housing.
