description 1. Field of the Invention An enhanced illumination system for a micro-display comprises an illuminator for a reflective display panel having a light source and a prism. The prism has a first substantially planar face proximate to the light source and to the display panel, so that light propagates from the light source into the prism through the first face and is redirected to the display panel through the first face. A second face of the prism is positioned opposite the light source so that light reflected from the display panel impinges on the second face and propagates to imaging optics. The illuminator may also include an auxiliary prism optically coupled to the second face of the first prism to correct for astigmatism of the reflected light from the display panel and a beam splitter between the first prism and the auxiliary prism.
