Researchers at the University of Cincinnati and Sun Chemical (both in Cincinnati, OH) have developed a lithographically fabricated electrofluidic display that uses visually brilliant color pigments and reaches a reflectivity value of 55percent with future potential to reach 85percent. The new technique differs from electronic-paper (e-paper) displays that use oils, dyes, or interference effects--such as electrowetting (see www.laserfocusworld.com/articles/302460), electrophoretic (see www.laserfocusworld.com/articles/348055), cholesteric liquid-crystal, or microelectro-mechanical systems (MEMS) interference-based displays (see www.laserfocusworld. com/articles/279829)--to achieve high-reflectivity (typically 50percent) color.
