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
$(\Delta
{\rm E}_{{\rm AVE}\_{\rm CIEDE2000}} < 0.2)$
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.
