Plasma display panel and driving method thereof

摘要

In a plasma display panel, a sustain discharge pulse voltage is applied to the scan or sustain electrodes while the address electrode is biased with a ground voltage, and a negative assistant pulse voltage is applied to an electrode that is not receiving the sustain discharge pulse. At least a part of a period for applying the negative assistant pulse is positioned prior to a period of applying the sustain discharge pulse. Discharge efficiency can be improved by applying the negative assistant voltage to the sustain electrode when the sustain discharge is applied to the scan electrode across a long discharge gap.
