Filed: 2002-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a plasma display which securely performs erasure discharge and hardly cause misdischarge even when a discharge maintenance period is made short corresponding to higher definition. SOLUTION: The width PWc of a pulse Pc applied in the latter half of a discharge maintenance period is made wider than the width PWb of a pulse Pb except a pulse Pa which is applied first and in an erasure period, erasure discharge is carried out by using so-called narrow-width pulses. Consequently, the wall voltage of a discharge cell can be made higher than before at the end of the discharge maintenance period, so the erasure discharge is securely performed and misdischarge is hardly caused.
