  • Publication number: 20050168799
    Abstract: A first electrophoretic medium comprises an electrically charged particle suspended in a suspending fluid, the particle having a polymeric shell having repeating units derived from at least one monomer the homopolymer of which is incompatible with the suspending fluid. A second, similar electrophoretic medium comprises a suspending fluid, and first and second types of electrically charged particle suspended in the suspending fluid, the two types of particle having differing optical characteristics but both having polymeric shells. The polymeric shells are arranged such that homoaggregation of the two types of particles is thermodynamically favored over heteroaggregation.

  • Publication number: 20050156340
    Abstract: Prior art processes for producing protein-based capsules (for example, capsules for use in electrophoretic media) tend to be wasteful because they produce many capsules outside the desired size range, which is typically about 20 to 50 ?m. Capsule size distribution and yields can be improved by either (a) emulsifying a water-immiscible phase in a preformed coacervate of the protein; or (b) using a limited coalescence process with colloidal alumina as the surface-active particulate material.

  • Publication number: 20050158674
    Abstract: This invention relates to a color silver halide photographic element comprising gelatin, a support bearing at least one dye image forming unit selected from a dye image forming unit comprising at least one red sensitive silver halide emulsion layer having associated therewith a dye-forming coupler, a dye image forming unit comprising at least one green sensitive silver halide emulsion layer having associated therewith a dye-forming coupler, and a dye image forming unit comprising at least one blue sensitive silver halide emulsion layer having associated therewith a dye-forming coupler; and a polymer represented by Formula 1.

  • Publication number: 20050151709
    Abstract: 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.

  • Publication number: 20050105159
    Abstract: An encapsulated electrophoretic display is produced by laminating an electrophoretic medium, comprising a plurality of discrete droplets (104) in a polymeric binder (106?), each droplet (104) comprising a plurality of electrophoretic particles dispersed in a suspending fluid, to a backplane (110) having at least one electrode at a temperature such that the polymeric binder (106?) flows and secures the electrophoretic medium to the backplane (110).
