Abstract
Techniques and mechanisms for providing illumination of a display. In an embodiment, a light guide includes a first portion to receive light, a second portion to output some or all of the light, and a third portion configured to propagate the light between the first portion and the second portion. The third portion forms a first deflection structure which adjoins, and extends between, respective surface regions of the first portion and the second portion. A light source is coupled to provide edgewise illumination of the light guide via the first portion. In another embodiment, the light propagates through the third portion and into a region, between two parallel planes, in which the second portion is located.
