ABSTRACT:
An edgelit illuminated display system has a transparent medium having first and second opposing surfaces and at least one edge operable with a light source for illuminating the first and second surfaces. A matrix of dots on each of the surfaces is arranged to allow interaction of light between the surfaces. The matrix of dots on at least one of the surfaces substantially covers the entire surface for providing an even increased illumination throughout the surface, wherein when a graphic image is supported over the surface the graphic image is evenly illuminated.
