Abstract: A backlight apparatus comprised of a light pipe with one or more light input ends, a top surface, a bottom surface, opposing side, a non imaging optic collimator and scatter inducing elements. The non imaging optic collimator causes the light rays entering into the light pipe to be directed towards the far end relative to the light input end in a specified angular distribution. Pluralities of scatter induced elements (SIE) are introduced in the body of the light pipe between the applicable light input end and the corresponding far end. Individual scatter induced elements may be formed in any geometry, and may be grouped or separated such that there exists a variation of SIE each individually or as grouped, possessing discrete geometries.
