<p>The screen includes n line electrodes (10) and m intersecting column electrodes (8), n control circuits (26i) for successively driving the n line electrodes, with n and m integers >/= 2, the control circuit of the line electrode Li, with i an integer such that 1</=i</=n, including means for applying a selection potential (VLs) to the line electrode Li for a first selection time, then a discharge potential (Vd) for at least a part of a second time for selection of at least one other line electrode (Li+1) and to set the line electrode Li to high impedence outside the first selection time and the said part of the second selection time, control circuits (24) for simultaneously applying potentials appropriate for display of information on the line Li simultaneously on the m column electrodes during the first selection time. <IMAGE></p> |
