29.2: Power‐Saving: A New Advantage of Multi‐Primary Color Displays Derived by Numerical Analysis

Abstract In this paper, we present the advantages of Multi‐Primary Color (MPC) display devices compared to the conventional display devices with three (red, green, and blue) primary colors. Not only do we review the well‐known advantages such as wide color gamut and wide viewing angles but also introduce the examples of numerical computation for the purposes of the luminance reproduction. According to the results, we also estimate the potentials of power‐saving for RGB, RGB + Yellow, and RGB + White systems. It is shown that MPC systems are much superior to RGB‐based systems in terms of power‐saving. Not only does RGB + Yellow system widens color gamut but also reduces power consumption by 20% with respect to RGB‐based systems.
