摘要： An electrophoretic medium has walls defining a microcavity containing an internal phase. This internal phase comprises electrophoretic particles suspended in a suspending fluid and capable of moving therethrough upon application of an electric field to the electrophoretic medium. The average height of the microcavity differs by not more than about 5 μm from the saturated particle thickness of the electrophoretic particle divided by the volume fraction of the electrophoretic particles in the internal phase.

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.

摘要： Electro-optic displays contain a plurality of types of electro-optic media within a single layer. One form of display has separate areas which undergo different color changes so that the display can blink the same image in different colors. A second form of display has areas which switch at different rates so that images can appear transiently. A third form of display has a medium comprising multiple types of electro-optic elements having differing color states and switching speeds to allow display of a wide color gamut.

摘要： The image stability of electrophoretic media, comprising a plurality of particles disposed in a fluid and capable of moving through the fluid upon application of an electric field to the medium, can be improved by including in the fluid either a polystyrene or an aggregating diblock copolymer which forms micelle-like structures in the fluid, the diblock copolymer having a first block soluble in the fluid and a second block not swellable by the fluid. In variable transmission electrophoretic media, haze can be reduced by using as the fluid a mixture of a partially hydrogenated aromatic hydrocarbon and a terpene.

摘要： The performance of electro-wetting displays can be improved by: (a) providing a concealment member (112) which conceals the moving fluid (108) when that fluid (108) is confined to a small area; (b) using the moving fluid to cover one or more sections of a filter or reflector having differently-colored sections; (c) moving the moving fluid between the rear surface and a side surface of a microcell; (d) using as a substrate for a moving fluid a substrate resistant to wetting by the fluid but pierced by multiple conductive vias capped with a material wetted by the fluid; and (e) coloring the moving fluid with pigments or nanoparticles.
