Abstract :
The reason for wider color gamut of laser display systems rests on RGB laser lights whose color coordinates very approach the locus of gamut chart, which means the most saturated colors. A novel, practical and simplest method to reduce the laser speckle is developed. A laser digital cinema projector (LDCP) is manufactured for the first time in the world. The LDCP enjoys all benefits of 166% NTSC expanded color gamut, beyond 9 024 ANSI lumens light output, a minimum sequential contrast ratio of 2595:1, 2048 X 1080 display resolution, etc.
