Abstract

1465701 Electro-phoretic suspension; controlling light PLESSEY CO Ltd 17 Oct 1974 [22 Nov 1973] 54325/73 Headings G2F and G2H An electro-phoretic suspension, which is used in a display device, comprises a dispersion in a suspension medium of particles each including a body of an inactive organic compound at least partially surrounded by a dielectric, the body being such as to effect a density match between the medium and the particles. The bodies may contain lightreflective cores or be impregnated with fluorescent dye. Core materials which may be used are listed. Preferably the bodies are of poly (acrylonitrile), polyethylene or poly (trimethylpentene) and the dielectric is TiO 2 , SiO 2 , Al 2 O 3 or hydrous forms of these oxides.
