Abstract
An electrophoretic medium comprises a fluid and at least one species of particles disposed, When a first addressing impulse is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.
