Abstract
An illumination system for a display device includes a plurality of lenslets which provide partially collimated light with respect to at least one axis of the display. A light box provides uncollimated light to the lenslets. The light box includes a reflector having apertures which transmit light from the light box to the lenslets. The internal surfaces of the light box and the reflector are highly and diffusely reflective and a high percentage of the light reaches the lenslets.
