Abstract (en)

[origin: WO2014184373A1] At least one of the two rectangular conducting planes, P1, provided to apply a voltage at the terminals of each of the pixels of a matrix, is powered by two adjacent edges b3 and b4 from individual voltage sources Sv1 to sv6 and Sh1 to Sh6 distributed along each of the edges. The voltage sources have different voltage values, preferably but not necessarily varying in an increasing monotonic manner between a low value Vh1 and Vv1 on the side of junction J between the two edges b3 and b4 and a high value Vh6 and Vv6 on the other side of each of the edges. The two edges b3 and b4 by which the conducting plane is mainly powered are cut to form electrical contact points that are locally insulated from each other and spaced apart at regular intervals, each being powered by an individual respective source of voltage. The other conducting plane can be powered in the same way.
