Electro-fluidic displays (EFDs) are one of the most promising reflective displays due to their full color and video speed. Colored EFD oil, normally formulated by dissolving soluble organic dyes in non-polar solvent, dominates the color, electro-optical behavior and reliability performance of electro-fluidic display devices. In this paper, novel perylene-based organic dyes for electro-fluidic displays, which can cover yellow, orange, red, magenta and cyan colors, were synthesized. The absorbance, electro-optical and light stability properties were tested; the results showed that the perylene-based organic dyes are especially suitable for EFDs.
