Abstract:
1. An apparatus for viewing stereoscopic images comprising: a first passive viewing lens including a first polarization layer, the first polarization layer configured to permit light having a first polarization orientation to pass through the first polarization layer, the first passive viewing lens further including one or more first birefringence compensation layers, wherein the one or more first birefringence compensation layers are configured to compensate for decomposition of rays of light into ordinary rays and extraordinary rays as the rays of light pass through two or more liquid crystal display layers and a cooperating birefringence compensation layer of a stacked liquid crystal display, wherein a particular first birefringence compensation layer of the one or more first birefringence compensation layers is associated with the cooperating birefringence compensation layer of a particular liquid crystal display layer of the stacked liquid crystal display; and a second passive viewing lens including a second polarization layer, the second polarization layer configured to permit light having a second polarization orientation to pass through the second polarization layer, the second polarization orientation being different from the first polarization orientation, the second passive viewing lens further including one or more second birefringence compensation layers, wherein at least one of the one or more first birefringence compensation layers comprises at least one first uniaxial film having an optical axis parallel to the plane of the film, and wherein at least one of the one or more second birefringence compensation layers comprises at least one second uniaxial film having an optical axis perpendicular to the plane of the film.
