A method to design the optimal four-primary color gamut for reproducing maximum input encoded color was presented. Based on the maximum color gamut volume (CGV) intersection requirement, the high-fidelity color reproduction can be achieved. A four-primary-LED backlight module which offers the flexibility to design different CGV was constructed as a platform for verifying the different algorithms. Two major encoding color gamuts, "sRGB" and "real surface color gamut," are the evaluation targets. Calculations are performed under two commonly-adopted criteria, maximum white point luminance and maximum CGV, and the proposed one, maximum intersectional CGV, respectively. Result shows the proposed method is demonstrated to reproduce maximum input color gamut, it can display more vivid image when apply to the large input encoding signal.
