Color Electronic Paper with Front Light

Abstract

The color electronic paper (CEP) can be realized by printing color inks on a black/white electrophoretic display. However, the overall lightness will be significantly reduced. A good solution to this issue is to equip it with a front light panel to enhance the overall brightness and colorfulness. This paper presents a color reproduction system for this new CEP. Comprehensive approaches to color gamut estimation, best front light selection, and gamut mapping for various front light settings are presented.
