Abstract:
A light pipe includes a light input end and a diffractive structure. The diffractive structure includes elongated formations having diffractive properties for coupling light out from the light pipe to provide backlighting of a flat-panel display. The elongated formations are curved, the curvature being dependent on the location of a light source at the light input end.
