Abstract
A three dimensional viewing system for use with a VCR for the three-dimensional viewing of an image having right-eye and left-eye subimages in alternating sequence reproduced by the VCR wherein the VCR generates a switching pulse which is in synchronization with the alternating sequence. The three dimensional system comprises a pair of three-dimensional viewing glasses having a pair of lenses made of a liquid crystal material through which the right-eye subimage and the left-eye subimage are viewed by regulating the on/off states of the lenses; a pulse generator for generating a driving pulse adapted to activate the liquid crystal material; and a mixing circuit for multiplexing the switching pulse and the driving pulse to produce an on/off driving signal divided into a first and a second driving signals that are 180 degrees out of phase with each other wherein each of the first and the second driving signals is used to regulate the on/off states of the lenses.
