Patent ID: 8581969

Claim:
A system, comprising: logic providing content for display, the content including a first subset of frames targeted to a first eye of a user and a second subset of frames targeted to a second eye of the user; a polarized filter; a liquid crystal; and a projector receiving the content from the logic and projecting both the first subset of frames and the second subset of frames of the content through the polarized filter and the liquid crystal for stereoscopic viewing of the content by the user with passive glasses; wherein the polarized filter and liquid crystal are controlled such that the polarized filter and the liquid crystal are in a first orientation when a frame of the first subset of frames of the content is projected through the polarized filter and the liquid crystal, and the polarized filter and the liquid crystal are in a second orientation when a frame of the second subset of frames of the content is projected through the polarized filter and the liquid crystal; wherein the system is operable such that controlling of the polarized filter and the liquid crystal is such that the polarized filter is in a first position when the frame of the first subset of frames of the content is projected through the polarized filter and the liquid crystal, and the polarized filter is in a second position at 90 degrees to the first position when the frame of the second subset of frames of the content is projected through the polarized filter and the liquid crystal.
