Title: Plasma display apparatus and driving method thereof

Abstract: The present invention relates to a plasma display apparatus and a driving method thereof in which an erroneous discharge, a misdischarge and an abnormal discharge are prevented, a darkroom contrast is increased, an operation margin is widen, and an influence of a lower substrate wall charge is reduced in a sustain discharge. The plasma display apparatus and its driving method is characterized in that when the plasma display panel has a second temperature higher than a first temperature, a period between the last sustain pulse generated during a sustain period of (n-1).sup.th sub-field ("n" is a positive integer) and an initialization signal generated during a reset period of n.sup.th sub-field is more lengthened than when it has the first temperature. The plasma display apparatus and its driving method is characterized in that a pre sustain pulse (PRESUSP) rising from a sustain bias voltage (Vzb) is applied to the second electrode in the sustain period.
