Patent ID: 8138993

Claim:
A method for controlling a plasma display panel, comprising: performing a precharge or a predischarge of at least all cells of a current line that have to switch state for a next line by connecting an intermediate supply terminal that applies an intermediary supply voltage to output terminals of column control stages corresponding to junction points of first and second switches between first and second supply voltage terminals that apply first and second supply voltages, respectively, the intermediary supply voltage maintaining a voltage between the first and second supply voltages; disconnecting said output terminals from the intermediate supply terminal; and connecting each output terminal to the first or to the second power supply voltage by turning on the first or second switch of a corresponding stage of the column control stages, according to an addressing reference value, wherein, during the precharge or the predischarge, said act of connecting each output terminal to the first or to the second power supply voltage is delayed at the intermediary supply voltage with respect to the act of disconnecting the output terminal from the intermediate supply terminal.
