Abstract

An optical projection system (50) comprises a light source (12), a substantially planar optical element array (54) for receiving light emitted from the light source (12), and a display panel (58) for selectively outputting light from the optical element array. The optical element array (54) includes an optically transmissive substrate material and a plurality of optical micro-elements formed on at least one surface of the substrate material. The display panel (58) has a plurality of pixels for selectively outputting light output from the optical element array (54). The micro-elements can include micro-lenses, micro-prisms, micro-waveguides, or any suitable combination of the foregoing, configured to alter the characteristics of light emitted from the light source to create a desired illumination source.
