Illumination system for a display device.

摘要

An illumination system for a display device (10) includes a plurality of lenslets (17,17a,27) which provide partially collimated light with respect to at least one axis (21,29) of the display. A light box (11) provides uncollimated light to the lenslets. The light box includes a reflector (13) having apertures (19,28) 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.
