PURPOSE: A wireless driver for stereoscopic image spectacles is provided to simultaneously see a stereoscopic image by a plurality of wire/wireless users by automatically changing an image by an interlaced scanning method. CONSTITUTION: A modulation frequency generator(202) frequency-modulates an LCD shutter drive signal of stereoscopic image spectacles from a signal input monitor(118). An infrared ray transmitter modulates a vertical sync signal divided by a vertical sync signal divider(116) to an infrared ray sync signal. A high frequency transmitter(220) modulates the vertical sync signal to a high frequency sync signal according to a modulation frequency from the modulation frequency generator(202). Infrared ray stereoscopic image spectacles(218) receives an infrared signal from an infrared ray generator(210) and drive left and right LCD shutters. High frequency stereoscopic image spectacles(226) receive the high frequency sync signal from the high frequency transmitter(220) and drive the left and right LCD shutters. A voltage regulator(106) supplies necessary powers to each part.
