Abstract

An electrophoretic display comprising at least one in-plane gating electrode. The gating electrode(s) provide a gating effect, which raises the effective threshold voltage to prevent the undesired movement of the charged particles in the cells. The design of the invention can be manufactured using low cost materials by efficient processes.
