FLAT PANEL DISPLAY LIGHTING SYSTEM

摘要

A flat panel display lighting system is disclosed wherein a thin, flat light guide (11) has two spaced major surfaces (13, 14) with light introduced into one edge of the guide. Light is extracted from the light guide by the first facets (18) in a plurality of parallel microgrooves (17) 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 (19). A liquid crystal display (12) is placed adjacent to the light guide to be backlit or frontlit.
