emulsions tend to settle in parallel plate

An improvement is disclosed, which tends to retard the settling in parallel plate

electrophoretic displays. With reference to the drawing, the improved cell 10 consists of parallel plates 11 separated by spacers 12, The parallel plate cell

configuration has a single layered array of spherical, nonconductive particles 13 adhering to either or both of the plates/electrodes lie These spherical, nonconductive particles 13 are insoluble in the solvents and have a diameter equal

to the cell space width between the parallel plates/electrodes lie The space between the spherical, nonconductive particles 13 contains the electrophoretic emulsion (dye 14 and pigment 15). This configuration allows the emulsion (dye 14

and pigment 15) to be contained in the "pocket.~like"areas within the display. Any local pigment settling could be overcome by regenerating the cell 10 with an applied field, Contrast density would not be impaired to any great degree, and the display would acquire a halftone appearance,
