Abstract: An electrophoretic display apparatus includes an array of cells each comprising first and second electrodes and a plurality of electrophoretic particles disposed between the electrodes, wherein the particles are dispersed in a host fluid and are multistable in positions between the electrodes; and drive circuitry in electrical communication with each of the electrodes. The drive electronics are configured to transition addressed cells of the array from a first optical state to a second optical state with a plurality of successive write signals.
