摘要： An electrophoretic display device includes a display layer of a multiplicity of individual microcapsules containing a display medium therein 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 includes one or more set of colored particles in a dielectric fluid and has an electric conductivity of about 10−11 to about 10−15 S/m. The microcapsules may be made by encapsulating the display medium in the wall forming material of the microcapsules, and for example a complex coacervation process may be used.

摘要： A display medium for an electrophoretic display device includes a liquid system, at least one thermally reversible gelling agent, and at least one set of particles exhibiting a color. Inclusion of the gelling agent enables an image formed in the display device at an elevated temperature of about or above the melting point of the gelling agent to be fixed in a gel state, e.g., at temperature of about or below a gel point of the gelling agent. The image thus has stability, even in the absence of an applied electrophoretic field.
