ABSTRACT:
Methods form multi-color electrophoretic displays. The method includes providing a solution containing microcapsules, wherein the microcapsules comprise a shell that is transparent and a display medium within the shell, wherein the display medium comprised of either (a) at least two sets of differently colored particles in a substantially clear fluid, or (b) at least one set of colored particles in a differently colored fluid. The method includes dispensing the solution onto a substrate, wherein a display layer of microcapsules is formed on the substrate. The method includes positioning a conductive substrate adjacent to the substrate, wherein the substrate is located between the display layer and the conductive substrate, wherein the conductive substrate applies an electric field to at least one microcapsule of the display layer, wherein the sets of particles of each microcapsule in the display layer are movable within the microcapsule by the electric field to be displayed.
