ABSTRACT:
A driving method and a driver circuit for improving the definition of display image on a plasma display device. In an initial state in an addressing discharge period, a scanning electrode is applied with a scanning base pulse at a first power supply potential. This suppresses a weak erroneous discharge between a scanning base pulse and a display data pulse. Next, the scanning electrode is applied with a scanning pulse. After the scanning pulse has been applied, the scanning electrode is applied with the scanning base pulse at a second power supply potential. In this way, the level of the scanning base pulse applied to the scanning electrode after the end of the application of the scanning pulse in the addressing discharge period is lower than the level of the scanning base pulse applied to the scanning electrode before the application of the scanning pulse. This ensures a potential difference between the scanning electrode and the sustain electrode, and facilitates the formation of a wall charge required for a sustain discharge in the next discharge sustain period.
