Electrophoretic display mediums, devices and methods of displaying images with such devices

摘要

Provided is an electrophoretic display device, comprising a display layer comprised of a multiplicity of individual microcapsules (45) containing a display medium therein and conductive substrates (10,20), at least one of the conductive substrates (10,20) being transparent, wherein the display layer is located in between the conductive substrates, and wherein the display medium comprises one or more set of colored particles (74) in a dielectric fluid (73) and has an electrical conductivity of about 10-11 to about 10-15 S/m.
Furtheremore, there is provided a method of forming such an electrophoretic display device and the individual microcapsules (45) and their walls.
