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.
Claims24
An electrophoretic display comprising
- (a) electrophoretic cells filled with charged particles dispersed in a dielectric solvent;
- each said cell being positioned between a top electrode layer and a bottom electrode layer, said top electrode layer comprising at least one driving electrode positioned over more than one cell and said bottom electrode layer comprising at least one driving electrode positioned under more than one cell;
- and
- (b) at least one in-plane gating electrode.
