Abstract:
1. A method for forming a multi-color electrophoretic display, the method comprising: providing a solution containing microcapsules dispersed in a liquid, wherein the microcapsules comprise: dispensing the solution onto a substrate, with a water absorbent layer on an opposite side of the substrate from a side of the substrate onto which the solution is dispensed, wherein a display layer of microcapsules is formed on the substrate, and wherein the water absorbent layer absorbs the liquid of the solution dispensed onto the substrate; subsequently removing the water absorbent layer with the absorbed liquid; 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, and wherein the sets of particles of each microcapsule in the display layer are movable within the microcapsule by the electric field so as to be displayed.
