Abstract

The quantitative description of the size of a display gamut is crucial for designing the wide-gamut display of high saturation primaries. Three methods are proposed for the calculation of the number of discernible colors in a display gamut volume. The methods are demonstrated with a comparison of two mobile phone displays, one based on AMOLED technology and the other based on LCD technology. The AMOLED has 60-80% more discernible colors than the LCD display. Not only is the result relatively invariant to the computational method but it is also similar when the analysis is carried out in CIELAB space or CIECAM02 space.
