    摘要: The invention relates to methods and materials for controlling stability and color intensity in an electrophoretic display element. Filler particles in the electrophoretic display element, serves as a medium that the electrophoretic particles must travel through during switching between optical states of the display. The filler particles provide improved control over the color intensity of the electrophoretic display element. In addition, the filler particles create resistance to the migration of the electrophoretic particles, thereby improving the bistability of the electrophoretic displays and inhibiting settling of the electrophoretic particles. Also, migration resistance provided by the filler particles can enable threshold addressing of an electrophoretic display.

    摘要: A coating of an encapsulated electrophoretic medium is formed on a substrate (106) by dispersing in a fluid (104) a plurality of electrophoretic capsules (102), contacting at least a portion of a substrate (106) with the fluid (104); and applying a potential difference between at least a part of the portion of the substrate (106) contacting the fluid (104) and a counter-electrode (110) in electrical contact with the fluid (104), thereby causing capsules (102) to be deposited upon at least part of the portion of the substrate (106) contacting the fluid (102). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps. Alternatively, patterned coatings of capsules may be formed by applying a fluid form of an electrophoretic medium to a substrate, and applying a temporally varying voltage between an electrode and the substrate. The process may be repeated to allow for deposition of full color displays.
