Abstract
An image display system comprises red, green and blue laser light sources, a spatial light modulator that modulates the laser light of different colors in a time sharing manner and a controller that controls the operation of the laser light sources and the spatial light modulator. The green and red laser light sources are lit in this order in each frame. The green color is diminished due to the response delay of the spatial light modulator, but the green laser light produced by the green laser light source has a relatively large color phase shift from the standard green color so that the shortage of green color cancels the color phase shift of the generated green color so that the color phase shift of the displayed intermediate color can be minimized.
