Patent ID: 7868849

Claim:
A method for driving a plasma display panel, the plasma display panel including a plurality of scan electrodes, a plurality of address electrodes crossing the plurality of scan electrodes, and controller for driving the panel, the method comprising: dividing the plurality of address electrodes into a plurality of address electrode groups; applying a scan pulse to each of the plurality of scan electrodes in accordance with a scan sequence during an address period of a plurality of sub-fields; and applying a data pulse to each of the plurality of address electrode groups in association with a scan pulse, wherein a starting time point of the data pulse for at least one of the plurality of address electrode groups is different from that for the other address electrode groups during an address period of at least one of the sub-fields, wherein the width of the scan pulses applied to a predetermined number of the plurality of scan electrodes during an address period of at least one sub-field is greater than the width of the scan pulses applied to the remaining scan electrodes, wherein a starting time point of a scan pulse is offset from all of the starting time points of data pulses that are applied to the plurality of address electrode groups, wherein the width of the scan pulses applied to the predetermined number of the plurality of scan electrodes is gradually reduced from the first scan electrode, and wherein the difference between the widths of the scan pulses applied to the first scan electrode and an adjacent second scan electrode is the same as the difference between the widths of the scan pulses applied to the second scan electrode and an adjacent third scan electrode.
