ABSTRACT:
In a driving method of a plasma display device, a final voltage of a falling ramp voltage is set to a discharge firing voltage of all the discharge cells after applying a gradually rising ramp voltage during a reset period. A difference in voltage applied to an address electrode and to a scan electrode is set to be greater than the maximum discharge firing voltage in turn-on discharge cells in an address period. A bias voltage applied in a rising reset period, an address period, and a sustain period of subfields that express low grayscales is increased, and the address electrode is biased with a positive voltage in the sustain period. With this configuration, the problem of worsening the margins by loss of wall charges is solved since addressing is not influenced by the wall charges and performance of expressing low grayscales is increased.
