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.

摘要: A plasma display apparatus is disclosed. The plasma display apparatus includes a plasma display panel including a first electrode and a second electrode connected to a reference voltage source, a negative voltage controller that supplies a negative voltage output from a negative constant voltage source to the first electrode, a sustain driver, and a negative voltage blocking unit. The sustain driver supplies a sustain signal to the first electrode, and one terminal of the sustain driver is connected to one terminal of the negative voltage controller. The negative voltage blocking unit prevents the negative voltage from being supplied to the reference voltage source through the sustain driver while the negative voltage controller supplies the negative voltage to the first electrode.
