ABSTRACT:
A display includes a substrate having front and rear sides and defining one or more optical paths. A light source corresponding to each optical path is associated with the rear side of the substrate. Light propagates from the light source to the front side of the substrate through the corresponding optical path. Offsetting the light source from the centerline of the optical path improves light diffusion by promoting light reflection off the sides of the optical path. Multiple light sources of different colors can be associated with each optical path to provide for variable color output from each optical path at the front side of the substrate.
