<P>PROBLEM TO BE SOLVED: To provide an LED display device and stereoscopic glasses which enable an observer in a wide area to observe an image in a stereoscopic view. <P>SOLUTION: The LED display device shifts the light emitting wavelengths of LEDs by changing the driving currents from first currents to second currents, and displays an image for a right eye and an image for a left eye with different light emitting wavelengths. The stereoscopic glasses use a filter which makes either first wavelengths before the light emitting wavelengths are shifted or second wavelengths after the light emitting wavelengths have been shifted transmit therethrough as a light control member for the right eye or the left eye. <P>COPYRIGHT: (C)2012,JPO&INPIT |
