Abstract
Because the trichromatic coordinates of the laser display devices used in the wide gamut and are greatly different from the exiting television (TV) signals. Therefore when the TV signals is input to drive the laser display device, color distortion and color deviation may occur to influence the subjective experience. In order to solve this problem, it is necessary to input signals under a certain rule to expand the small color gamut to the large color gamut for the laser display devices. The gamut expansion mapping method is studied to show better color performance for human perception based on laser display device.
