Patent ID: 7286102

Claim:
A method for driving a plasma display panel that includes an upper plate provided with a plurality of electrode pairs each having a first and a second electrode, a lower plate provided with a third electrode crossing the electrode pairs, and a cell arranged in a matrix at each intersection part of the electrodes, comprising: applying an initialization signal to the first and second electrodes to initialize cells, the initialization signal has at least one rising part where a voltage rises and at least one sustain part where the voltage is sustained; applying a scan signal to any one of the first and second electrodes, and data to the third electrode to select the cells; and alternately applying sustain signals to the first and second electrodes to carry out a display for the selected cells; and applying a pre-erase signal to any one of the first and second electrodes after applying the scan signal to any one of the first and second electrodes, and data to the third electrode and before applying the sustain signals to the first and second electrodes, wherein the pre-erase signal is a ramp waveform, the voltage level of which increases with a rising slope.
