Abstract:
A display system comprising:a reflective display having a plurality of pixels, each of which in an active mode is responsive to on-axis light that is generally perpendicular to the surface of the display for reflecting the on-axis light to generate an image;a light source positioned off-axis with respect to the display;an illumination system with a single beam splitter for directing light to the display, the illumination system having a prism with a first surface for reflecting light from the light source to a beam splitter surface, the beam splitter surface reflecting light from the first prism surface to the reflective display so that the light is generally perpendicular to the surface of the display to generate an image and the beam splitter passing therethrough light reflected from the display;a lens disposed between the prism and the display to minimize chromatic aberrations; andan imaging optical system receiving light passed through the beam splitter from the display for providing an enlarged virtual image.
