<P>PROBLEM TO BE SOLVED: To provide a method of driving a plasma display panel by which stable address discharge can be performed even if maintenance tape transport board for driving a maintaining electrode is omitted. <P>SOLUTION: A reset operation, address operation and maintaining discharge operation are performed by applying a driving waveform to a scan electrode in the state that the maintaining electrode is biased to a grounding electrode. As a result, the driving board for driving the maintaining electrode can be omitted. If the maintaining electrode is biased to the grounding voltage, a low voltage is applied to the scan electrode in a reset period and therefore the potential by wall charge of the scan electrode turns higher than the potential by the wall charge of an address electrode. In this case, when a rising waveform is applied in the reset period, a strong discharge takes place in some cases between the address electrode and the scan electrode and consequently, the address electrode is biased to the specified voltage and a plurality of the scan electrodes are divided to a plurality of groups, and the scan pulses of different voltages are applied to the scan electrodes in the address periods by each of the respective groups. As a result, the stable address discharge can be generated in the address period. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
