Abstract
For three-dimensional viewing of television and movies, in the format wherein left-eye and right-eye images are presented alternately on the screen, a pair of 3-D viewing glasses have correspondingly alternating on/off left and right lenses. The lenses each contain liquid crystal material which varies from a nearly totally obscured state by scattering, to nearly 100% transmission, as controlled by a signal from the television or movie projector. In this way, in instances when the left-eye image is presented on the screen, the left-eye lens is 'ON' so that the viewer sees the image with his left eye, and when the right-eye image is presented on the screen, the right-eye lens is 'ON' to enable the viewer to see that image with his right eye. The two images on the screen are taken from different photographic angles, and the images alternate at a sufficient frequency for the viewer to perceive that both images are occurring at once, and he sees them as a composite three-dimensional image.
