LUMINANCE INHANCEMENT OPTICAL SUBSTRATE WITH ANTI-INTERFERENCE-FRINGE STRUCTURE

摘要

PURPOSE: An improved luminance optical substrate with an anti-interference-fringe structure reduce an interference-fringe in low price. CONSTITUTION: An optical substrate having unevenness comprises: a substrate; an light input side(52) on one side of the substrate; a uneven light output side(54) on the backside of the substrate; and prisms which are arranged in parallel with the light output side.
