Abstract (en)

[origin: WO2007071679A1] The method comprises, in addition to the sending periods, depolarization periods during which a predetermined depolarization voltage V<SUB>prog-pol</SUB>, which exhibits an opposite polarity to the opposite polarity to the voltage applied during the sending periods, is applied and maintained on the control terminal of said control circuits of the panel, and a depolarization reference voltage V<SUB>ref.P</SUB>, which is different from the sending reference voltage V<SUB>ref.E</SUB>, is applied to the reference electrodes (Y<SUB>R</SUB>) to which reference terminals (R') of the control circuits are connected. This method makes it possible to use conventional and economic means of column control.
