Abstract
An electro-optical display system for visually displaying a polarized spatially multiplexed image (SMI) of a 3-D object for use in stereoscopic viewing thereof with high image quality and resolution. In the illustrative embodiment, electro-optical display system comprises a liquid crystal display device and a micropolarization panel of electrically-passive construction. The liquid crystal display device has a display surface for visually displaying a composite pixel pattern representative of a spatially multiplexed image composed of first and second spatially modulated perspective images of the object, consisting of first and second pixel patterns. The micropolarization panel includes an optically transparent laminate portion and an optically transparent substrate portion which is in direct physical contact with the laminate portion. First and second optically transparent patterns are permanently formed in the optically transparent laminate portion. The first optically transparent pattern spatially corresponds to and is spatially aligned with the first pixel pattern displayed on the display surface so as to impart a first polarization state P.sub.1 to light emanating from the first pixel pattern and passing through the first optically transparent pattern. The second optically transparent pattern spatially corresponds to and is spatially aligned with the second pixel pattern displayed on the display surface so as to impart a second polarization state P.sub.2 to light emanating from the second pixel pattern and passing through the second optically transparent pattern.
