Abstract
Set forth is a method of forming an electrophoretic display device that includes locating a multiplicity of individual reservoirs containing a display fluid between conductive substrates, at least one of which is transparent, to form a device, wherein the display fluid comprises at least two sets of particles in a liquid medium, the at least two sets of particles exhibiting a different color, and charging each of the sets of particles to have a different charge via application of an electric field to the device. This field induced charging of the sets of differently colored particles enables low conductivity particles with superior electrophoretic mobility to be achieved.
