An electrophoretic display has a substantially two-dimensional arrangement of microcapsules each having therein an electrophoretic composition of a dielectric fluid and a suspension of particles that visually contrast with the dielectric liquid and also exhibit surface charges; a pair of electrodes, at least one of which is visually transparent, disposed on and covering opposite sides of the microcapsule arrangement; and means for creating a potential difference between the two electrodes, the potential difference causing the particles to migrate toward one of the electrodes. The display may be powered by one or more piezoelectric elements, which are also suitable for powering other types of nonemissive displays.

[ What is claimed is:] [1.] An electrophoretic display comprising:a. an arrangement of discrete microscopic containers, each container being no longer than 500 .mu.m along any dimension thereof;b. first and second electrodes disposed on and covering opposite sides of the arrangement, at least one of the electrodes being substantially visually transparent;c. means for creating a potential difference between the two electrodes; andd. within each container, a dielectric fluid and a suspension therein of particles exhibiting surface charges, the fluid and the particles contrasting visually, the potential difference causing the particles to migrate toward one of the electrodes.
