Abstract
A front-lit display, having a ridged transparent film thereon. The ridges on the film bend glancing light rays down into the display. The light rays are reflected by a reflector below the display, pass back through the display, and exit the film in a direction substantially normal to the display. Thus, the ridged film enhances the brightness of the display for a given light source.
