Abstract

Many kinds of display technology such as LCD, OLED, quantum dot and laser display are developing rapidly. The final purpose of display technology is to achieve wider color gamut. Traditional method uses planar chromaticity diagram in CIEXYZ space to describe color gamut. This method did not use uniform color space and cannot deal with the situation of display systems with four or more primaries. In our previous work, we have already established a theory based on Macadam’s theory to calculate the stereoscopic color gamut for RGB laser display systems. In this letter, we extend this theory to display systems with four or more primaries. By using our algorithm, we calculate the stereoscopic color gamut of multi-primary display system. We set a four primary display system as an example. The center wavelength of the primary are set as 467nm, 520nm, 532nm and 630nm, white point is set as D₆₅(x=0.3127, y=0.3290), and color gamut has been calculated in CIELAB color space. Results show that when the ratio of the intensity of four primary is 1.0000：0.7490： 0.4316：1.5000, the largest gamut is obtained, whose value is 2.1030*10⁶. These results can be used in engineering to optimize the intensity of the primaries in four primaries display systems.
