1. A display device comprising:

  • a system of pixels arranged in rows and columns, a line selection circuit coupled to the pixels via a system of row electrodes and which, during operation, selects rows of pixels by means of selection voltages applied to the rows of pixels via the row electrodes, and a circuit for presenting, via a system of column electrodes, column or data voltages to the pixels during row selection, characterized in that the line selection circuit selects in sequence consecutive rows of pixels within groups of at least two rows of pixels during operation and charges consecutive groups of pixels in the opposite sense, and wherein the line selection circuit applies a selection voltage to at least one row electrode or selection electrode at the beginning or the end of a group of rows during operation, which selection voltage differs from the other selection voltages applied within said group of rows.
