Abstract
A backlight assembly uses one or more lighting elements and a light guide to provide backlight with a reduced number of lighting elements. The light guide is optically coupled with the one or more lighting elements and is configured to receive light at one or more locations, internally reflect the light at the extremities of the light guide, extract the light from the light guide, and radiate the light from a surface of the light guide to backlight an area.
