Abstract
An image display system stereoscopically reproduces a visual scene and includes an image display unit with a pair of LCD panels each starting its operation in response to a start pulse received every vertical field of an input video signal; a source of input video signals representing right and left stereoscopic video images every field; a circuit for generating right and left start pulses, which are mutually in an opposite-phase relationship, in synchronism with the arrival of the right and left video images; and a driver for driving the pair of LCD panels by the right and left start pulses. The image display unit is shaped into a virtual viewer incorporated in a ski-goggle type frame which is adapted to be worn on a user's head. The video images displayed on the two LCD panels are refreshed alternately to obtain a flickerless image without the necessity of employing any particular circuit or terminal.
