    摘要: A plasma display apparatus, and more particularly, a driving method and improved structure of a plasma display apparatus are provided. A sustain signal that alternates between a positive polarity and a negative polarity is supplied to only one electrode. Therefore, it can facilitate the adoption of an integrated driving board. Furthermore, a voltage magnitude of a set-up signal supplying in any one of the remaining sub-fields other than a first sub-field of a frame is less than the voltage magnitude of the set-up signal supplying in the first sub-field. It is therefore possible to increase the contrast.
