Abstract
The control of a plasma display panel, successively comprises, at least for all the cells of a current line having to switch state for the next line: a connection of a terminal of application of an intermediary supply voltage to output terminals of column control stages corresponding to the junction points of first and second switches between two terminals of application of a supply voltage, to perform a precharge or a predischarge of the screen cells; a disconnection of said output terminals from this intermediary voltage; and a connection of each output terminal to a first or to a second power supply voltage by the turning-on of the first or second switch of the corresponding stage, according to a luminance reference value, delayed with respect to the disconnection of the corresponding output terminal from the terminal of application of the intermediary voltage.
