ABSTRACT:
An apparatus comprises a display panel having a back side and a front side. A mirrored surface receives sunlight and reflects the sunlight towards a lens system. The lens system focuses the reflected sunlight and directs the focused light towards the back side of the display panel to provide backlighting for the display panel. The backlighting enables the front side of the display panel to be viewed with improved contrast. Preferably, the display panel is of the liquid crystal display (LCD) type, and the mirrored surface is parabolic in shape.
