ABSTRACT:
A flat panel display lighting system is disclosed wherein a thin, flat light guide has two spaced major surfaces with light introduced into one edge of the guide. Light is extracted from the light guide by the first facets in a plurality of parallel microgrooves disposed to intersect and transmit the light introduced into the light guide and reflected away from the major surface by reflection from second microgroove facets. A liquid crystal display is placed adjacent to the light guide to be backlit or frontlit.
