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 binder having a multiplicity of individual cavities therein that contain a display medium, and conductive substrates, at least one of the conductive substrates 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 in a dielectric fluid and has an electrical conductivity of about 10-11 to about 10-15 S/m.
