    摘要: An electrophoretic medium comprises a liquid and at least one particle disposed within the liquid and capable of moving therethrough on application of an electric field to the medium. The medium further comprises a free radical scavenger selected from the group consisting of (a) stable free radicals; and (b) polymeric free radical scavengers comprising a plurality of free radical scavenging groups attached to a polymeric chain. The medium is desirably encapsulated.

    摘要: An electrophoretic display comprises an electrophoretic medium having a plurality of charged particles suspended in a suspending fluid, and two electrodes disposed on opposed sides of the electrophoretic medium. At least one of the electrodes is light-transmissive and forming a viewing surface. The display has a closed optical state in which the charged particles are spread over substantially the entire viewing surface so that light cannot pass through the medium, and an open optical state in which the electrophoretic particles form chains extending between the electrodes so that light can pass through the electrophoretic medium. Insulating layers are disposed between the electrodes and the electrophoretic medium. Similarly electrophoretic displays are provided equipped with color filter arrays or reflectors.
