Abstract:
1. A display, comprising: a plurality of elements, each of said plurality of elements comprising multiple sectors, each of said multiple sectors having a different pigment thereon; a plurality of cavities in an elastomer medium, each of said plurality of cavities being arranged so as to constrain a motion of an associated one of the plurality of elements encapsulated therein; wherein each of the plurality of elements comprises a charge control agent selected so as to both reduce an influence of an electric charge established by said pigment and to increase an electric charge influence of said charge control agent relative thereto, wherein said increased electric charge influence of said charge control agent with respect to the electric charge established by said pigment is effective to control a monopole and a dipole charge effect of each of said plurality of elements so as to allow a precise translation of an element between walls of an associated cavity and to allow complete rotation of said element therein under an influence of an external electric field.
