Image display system

An image display system comprising:

• a red laser light source configured to emit red laser light;
• a green laser light source configured to emit green laser light having a relatively high y value in the CIE xy color space chromaticity diagram;
• a blue laser light source configured to emit blue laser light;
• a spatial light modulator configured to modulate the red, green and blue laser light emitted from the respective laser light sources in a time sharing manner according to a video signal;
• and
• a controller configured to control lighting of each laser light source during at least one lighting interval included in each video frame and to control an operation of the spatial light modulator;
• wherein the controller is configured to light the green and red laser light sources in this order in each frame, and
• wherein each frame consists of an odd number of lighting intervals, and a polarity pattern of the spatial light modulator is reversed from one frame to another.
