Patent ID: 8531509

Claim:
A stereoscopic viewing system comprising: a display device operable to: receive a video input; time division multiplex a presentation of left and right sub-frames of the video input; and transmit an infrared pulse having a timing corresponding to the presentation of the left and right sub-frames of the video input; and eyewear comprising an infrared detector and a pair of lenses, each lens comprising: a first filter operable to selectively transmit light polarized in a first direction from a light beam received from the presentation of the left and right sub-frames of the video input; a second filter operable to selectively transmit light polarized in a second direction from the light transmitted by the first filter; and a liquid crystal panel disposed between the first and second filters and operable to selectively change the polarization of the light transmitted by the first filter in response to a signal synchronized relative to a detection by the infrared detector of the infrared pulse transmitted by the display device; the liquid crystal panel comprising crystals that align from nonalignment during a rise response time in response to an applied voltage and return to nonalignment during a fall response time in response to removal of the applied voltage, the rise and fall response times being asymmetrical; wherein the first filter, second filter and liquid crystal panel of a first lens of the pair of lenses are relatively configured so that the first lens transmits light in response to the applied voltage and shutters light in response to removal of the applied voltage; and wherein the first filter, second filter and liquid crystal panel of a second lens of the pair of lenses are relatively configured so that the second lens shutters light in response to the applied voltage and transmits light in response to removal of the applied voltage.
