Abstract: Disclosed are novel reflective films having symmetrical reflection characteristics on the upper and lower surfaces thereof. Preferably, such films are made from cholesteric liquid crystal (CLC) material, wherein the pitch of the helices of the liquid crystal molecules therein varies along the thickness dimension (i.e. transverse to the surface) of the film. Depending on the final spiral structure of the materials utilized, the CLC circularly polarizing film materials reflect either left-handed or right-handed circularly polarized light. In a first illustrative embodiment, the CLC film has a laminated construction in order that both the upper and lower surfaces thereof have substantially the same reflection characteristics over its tuned reflection band. In second illustrative embodiment, the CLC film has a laminated construction in order that both the upper and lower surfaces thereof have substantially the same reflection characteristics over its broadband reflection band.

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. The electro-optical display system comprises a liquid crystal display device and a micropolarization panel of electrically-passive construction, laminated thereto. The liquid crystal display device visually displays a composite pixel pattern representative of a spatially multiplexed image composed of first and second spatially modulated perspective images of the object. The polarized light passing through first and second optically transparent patterns in the micropolarization panel form a polarized SMI which can be used to stereoscopically view the 3-D object with high image quality and resolution, by viewing the same through an electrically-passive pair of polarizing eyeglasses.
