A gyricon sheet includes a binder containing rotating elements, wherein the binder is swollen with dielectric fluids so as to have cavities larger than the rotating elements around each of the rotating elements, the cavities filled with the dielectric fluids, and wherein the dielectric fluids comprise a mixture of at least two liquids having different binder swelling capabilities. By selection of the mixture of dielectric liquids, the extent of swelling of the gyricon sheet can be precisely controlled, enabling the gyricon sheet to exhibit a high level of display brightness.
