Patent abstract
The present invention is directed to a driving method, in particular a three dimensional driving scheme for electrophoretic display devices. The method comprises applying a driving step in each of at least two electric fields to drive two types of pigment particles of different colors laterally and/or vertically for separately adjusting the grayscale and/or colors of the display. The present driving method has the advantage that the brightness and color intensity of the images may be separately tuned.
