Summary: | An electrophoretic medium comprises a fluid and a plurality of electrically charged particles disposed in the fluid and capable of moving therethrough on application of an electrical field to the medium. Each of the charged particles has a polymer coating comprising a first group. A polymer is dispersed in the fluid, this polymer having a plurality of second groups capable of attracting the first groups on the particles so that the polymer in the fluid forms a complex with the electrophoretic particles. |
