METHODS FOR DRIVING ELECTROPHORETIC DISPLAYS USING DIELECTROPHORETIC FORCES

摘要

A dielectrophoretic display is shifted from a low frequency closed state to a high frequency open state via a plurality of intermediate frequency states; the use of such multiple frequency steps reduces flicker during the transition. A second type of dielectrophoretic display has a light-transmissive electrode through which the dielectrophoretic medium can be viewed and a conductor connected to the light-transmissive electrode at several points to reduce voltage variations within the light-transmissive electrode.
