Abstract:
An electro-optical display system for visually presenting a polarized spatially multiplexed image of a 3-D object for use in stereoscopic viewing thereof with high image quality and resolution, said electro-optical display system comprising:a liquid crystal display device of electrically-active construction, having an image formation surface for forming a composite pixel pattern representative of a spatially multiplexed image composed of first and second spatially modulated perspective images of said object, said first spatially modulated perspective image consisting of a first pixel pattern representative of a first perspective image of said object spatially modulated according to a first spatial modulation pattern, said second spatially modulated perspective image consisting of a second pixel pattern representative of a second perspective image of said object spatially modulated according to a second spatial modulation pattern, said second spatial modulation pattern being the logical compliment pattern of said first spatial modulation pattern; a micropolarization panel of electrically-passive construction affixed to said image formation surface of said liquid crystal display device, said micropolarization panel including an optically transparent laminate portion directly mounted to said image formation surface, an optically transparent substrate portion in direct physical contact with said optically transparent laminate portion, for providing support to said optically transparent laminate portion, and first and second optically transparent patterns permanently formed in said optically transparent laminate portion; said first optically transparent pattern spatially corresponding to and being spatially aligned with said first pixel pattern formed on said image formation surface so as to impart a first polarization state P1 to light emanating from said first pixel pattern and passing through said first optically transparent pattern; said second optically transparent pattern spatially corresponding to and being spatially aligned with said second pixel pattern formed on said image formation surface so as to impart a second polarization state P2 to light emanating from said second pixel pattern and passing through said second optically transparent pattern, said second polarization state P2 being different than said first polarization state P1; said first and second optically transparent patterns physically interfacing each other at surfaces disposed above and substantially perpendicular to said image formation surface; and wherein the polarized light emanating from said first and second optically transparent patterns forms a polarized spatially multiplexed image for use in stereoscopic viewing said 3-D object with high image quality and resolution.
