Reset pulse driving for reducing flicker in an electrophoretic display having intermediate optical states

摘要: The present invention relates to a novel driving scheme for an electrophoretic display providing accurate intermediate optical states. According the invention, level of remnant voltage across pixels are taken into account when display. Remnant is built up resetting pixel between consecutive image states, and reset states therefore chosen so as avoid generation excessive levels. can example be implemented using counter, counting number uses same state extreme state, or look-up-table in which history mapped determines used next based on history. In effect, threshold avoided.
