Abstract

The invention relates to a method for driving a display cell filled with an electrophoretic fluid comprising two types of charged particles carrying opposite charge polarities and of two contrast colors, wherein the two types of pigment particles are dispersed in a solvent of a color or in a solvent with non-charged or slightly charged colored particles dispersed therein. The method comprises driving said display cell to display the color of the solvent or the color of the non-charged or slightly charged colored particles by applying a driving voltage which is about 1 to about 20% of the full driving voltage.
