Methods to Assess the Relative Number of Discernible Colors for Displays

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.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
