Abstract
A rotating element for use in an electric paper system in which the rotating element may be either substantially cylindrical or substantially spherical in shape and comprises at least three portions. Each portion has an associated optical modulation characteristic and the optical modulation characteristics of at least one portion are different from the optical modulation characteristics of at least one other portion. One of the portions is capable of being permanently magnetized. The rotating element also has an anisotropy for providing an electrical dipole moment. The electrical dipole moment renders the element electrically responsive such that when the rotating element is rotatably disposed in an electric field while the electrical dipole moment of the rotating element is provided, the rotating element tends to rotate to an orientation in which the electrical dipole moment aligns with the field.
