A scheme of color gamut measurement by color discrimination based on human eyes

Color gamut is an important parameter for display system. Wider gamut means that the system can display more colors. In this article, we designed an experiment to measure the color discrimination ability of human eyes in a certain range under different light sources such as LCD, LED, OLED and laser display, which has different center wavelength and spectrum-width. In our experiment, a Xenon lamp projector and a RGB laser projector were used to run the testing program. Eight volunteers` results showed that the gamut of RGB laser display is 49.48% larger than that of ordinary Xenon lamp display, and the standard deviation of the result was 8.7%.
