The present invention is directed to methods of passively driving an electrophoretic display. The electrophoretic fluid comprises three types of particles wherein two types particles are charged pigment particles having opposite charge polarities and contrasting colors. The third type of particle is larger in diameter than the first and second types of particles, and is less charged than the first and second types of particles, i.e., the third particle type is substantially uncharged. The electrophoretic medium is driven with two sets of electrodes, each set comprising a number of addressable electrodes.
A method for driving a passive matrix electrophoretic display between colored states, the passive-matrix electrophoretic display including a first set of electrodes on a viewing side of an electrophoretic medium and a second set of electrodes on a non-viewing side of the electrophoretic medium, wherein the electrophoretic medium includes first, second, and third types of particles, the first type of particles being oppositely-charged and differently-colored than the second type of particles, and the third type of particles being less charged and larger in diameter than the first and second types of particles, the method comprising:
