Patent abstract

An electrophoretic medium comprises a plurality of one or more types of particles suspended in a suspending fluid. The particles include at least one electrically charged, electrophoretically mobile particle capable of translating through the suspending fluid upon application of an electric field to the medium and at least one magnetic particle. A magnet is disposed adjacent the electrophoretic medium to introduce a threshold resistance to magnetic particle movement.
