Abstract:
1. A plasma display apparatus, comprising: a plasma display panel having a scan electrode and a sustain electrode, and an address electrode formed to intersect with the scan electrode and the sustain electrode; and a driving unit for providing a voltage difference between the scan electrode and the sustain electrode during an address period of at least one subfield of a frame to be larger than a voltage difference between the scan electrode and the sustain electrode during the address period in another subfield of the frame, wherein the another subfield is provided right after the at least one subfield in time, and wherein the driving unit controls the at least one subfield so as to exclude a sustain period in the at least one subfield or to exclude a sustain waveform during any sustain period of the at least one subfield, and the another subfield so as to include a sustain waveform during a sustain period of the another subfield, wherein the at least one subfield comprises a low gray level subfield having a lowest gray weight value among first, second and third low gray level subfields of the frame, and the at least one subfield and the another subfield is included in the same frame.
