Driving Apparatus and Method for Plasma Display Panel

The present invention relates to a driving device and a driving method of a plasma display panel, on the present invention the scan electrode and the sustain electrode at the time when the sustain period starts the magnitude of the sustain pulse applied to the scan electrode and the sustain electrode during the sustain period by generating the sustain discharge stable by adjusting in accordance with the wall charge distribution, there is provided a driving device and a driving method of a plasma display panel that increases the driving efficiency. The drive device of a plasma display panel according to the present invention includes a number of other sub-fields the number of times of light emission divided into a reset period, an address period, the sustain period, an image by applying a predetermined pulse to a scan electrode, a sustain electrode, an address electrode in each interval according to the driving apparatus of the plasma display panel to represent the scan electrode and the sustain electrode wall charge distribution of the reverse polarity pulse amplitude is adjusted according to the on at the time when the sustain period starts during the sustain period is applied to the scan electrodes of alternately Article characterized in that it comprises a second driver for applying to the sustain electrodes a first driving unit and the scan electrode at the time when the sustain period starts, and the sustain electrode pulse of the opposite polarity is scaled in accordance with the wall charge distribution on the alternately to do. In addition, the method of driving the plasma display panel of the invention is divided into the reset period, a number of other sub-fields the number of emissions, the address period, the sustain period, an image by applying a predetermined pulse to a scan electrode, a sustain electrode, an address electrode in each interval the method for driving a plasma display panel for expressing, during the sustain period, the sustain period begins in a reverse polarity is scaled according to the scan electrode and the wall charge distribution of the sustain electrode at the time when pulses are in the scan electrode are alternately applied and the scan electrode, and of the opposite polarity is scaled in accordance with the wall charge distribution of the sustain pulses of the electrode at the time when the sustain period starts to alternately characterized in that applied to the sustain electrode.
