Abstract
Field-sequential-color displays can have low power consumption and high spatial
resolution, but can suffer from annoying color breakup. Various approaches to suppress
color breakup have been presented in recent literature. However, a suitable color
breakup measure is necessary to compare the performances of those approaches, and is
also helpful for quick evaluation of algorithms and parameter settings. A perception
experiment was carried out to investigate the perceived color breakup with different
field color combinations, different light intensities, and different backgrounds. The
results indicate that the color difference and the relative contrast between fields have
a significant effect on the perceived color breakup, rather than the absolute luminance
value, which is different from existing metrics for color breakup visibility. Based on
this new insight, a computational metric for color breakup visibility is proposed and
discussed, which has a high correlation with the subjective scores (R<sup>2</sup>=0.945).
