E-paper has been approached as a “normal” display, and measurements are based on measurements as used for emissive displays, or at the very best reflective monochrome LCD. This may be adequate for grayscale e-paper displays, but as soon as color is added, these metrics are no longer suitable. This paper introduces a better way to evaluate color e-paper displays.
