Plasma display apparatus and driving method thereof

摘要

A plasma display apparatus comprises a scan electrode and a sustain electrode; a data electrode for intersecting the scan electrode and the sustain electrode; and a pulse controller arranged to apply respective pulses having opposite polarities to the scan electrode and the sustain electrode respectively during a reset period, and to apply respective negative sustain pulses to the scan electrode and the sustain electrode respectively during a sustain period, wherein the distance between the scan electrode and the sustain electrode is longer than that between the sustain electrode and the data electrode. Therefore, a surface discharge mode can be used even when applying negative pulses to the sustain electrode in a reset period. The size and cost of a plasma display apparatus can be reduced by applying a negative pulse of the same magnitude as a sustain voltage without the need to provide a separate negative voltage source.
