The first electrophoretic medium comprises electrically charged particles (700) suspended in a suspension fluid, wherein the particles (700) comprise repeating units derived from one or more monomers, wherein the homopolymer of the monomers is non-compatible with the suspension fluid Has a polymeric shell. The second, pseudo-electrophoretic medium comprises a suspension fluid, first electrically charged first and second type particles suspended in a suspension fluid, the two types of particles having different optical characteristics, but both polymeric shells . The polymeric shell is arranged such that homologous aggregation of the two types of particles is thermodynamically more advantageous than heterogeneous aggregation. |
