Patent ID: 8232960

Claim:
A method of displaying electrophoretic particles, comprising: configuring an electrophoretic display for directed spreading of electrophoretic particles across a number of substantially planar display electrodes by: controlling planar spreading of the electrophoretic particles in an electrophoretic pixel with an electrical field between an in-plane storage electrode and an in-plane activation electrode; and connecting the in-plane activation electrode to an in-plane display electrode, which extends across a first area in the electrophoretic pixel adjacent to a display aperture having a second area that is substantially coextensive with the first area; wherein the in-plane storage electrode and the in-plane activation electrode are positioned substantially coplanar with and at substantially opposite ends of the in-plane display electrode in an x-y plane and wherein the second area of the display aperture is positioned in a substantially z axis relative to the x-y plane of the in-plane display electrode.
