Abstract

In this paper, we present a methodology to characterize the colorimetric performance of a full-color electrophoretic display (EPD) with multiple pigment formation. We use the principal component analysis to formulate the composite hybrid color-mixing system by using a single eigen-spectral component for each sub-pixel channel. Proposed model was validated to predict the chromatic features with high accuracy (ΔE _{AVE_CIEDE2000} <;0.2) for both micro-cup type and micro-encapsulated type EPD samples. This study is effective to uncover the underlying physical features from only colorant-mixture information in a novel color system.
