Shuttering eyewear for use with stereoscopic liquid crystal display
Abstract:
An active eyewear method and system for viewing stereoscopic images is provided. The eyewear comprises polarization altering elements, such as twisted nematics or super twisted nematics, configured to receive light energy and rotate the polarization of light energy passing therethrough, and linear polarizers having polarization axes oriented in substantially identical orientations orthogonal to the first axis of polarization. The linear polarizers receive light energy from the polarization altering elements. The method comprises transmitting light energy through a sheet polarizer having an first axis of polarization, receiving the light energy with two polarization altering elements, each polarization altering operating out of phase with the other and in synchrony with a video field rate associated with the transmitting, and passing the light energy through two linear polarizers having substantially identical axes of polarization orthogonal to the first axis of polarization.
