A method for displaying an image with an electrophoretic display device that includes a multiplicity of individual reservoirs, each containing an electrophoretic display fluid, located between two conductive film substrates, at least one of which is transparent, includes appropriately applying an electric field and a magnetic force to a selected individual reservoir in a manner to cause either a first set of particles or a second set of particles of the display fluid to be displayed. The first set of particles exhibit a color different from and contrasting to a color of the second set of particles, and also preferably a different charging property. |
