Patent ID: 7580008

Claim:
A method of driving a plasma display panel (PDP), comprising: providing the PDP that comprises address electrodes, first electrodes and second electrodes intersecting the address electrodes, gray-scale levels being represented by combinations of sub-fields that include combinations of first type sub-fields and second type sub-fields, each sub-field comprising a reset period, an address period, and a sustain-discharge period; applying a rising ramp-shaped pulse to the first electrodes during each reset period, the rising ramp-shaped pulse starting from a reset start voltage; applying a falling ramp-shaped pulse to the first electrodes during each reset period after the application of the rising ramp-shaped pulse, the falling ramp-shaped pulse starting at the reset start voltage, a reset start voltage of the first type sub-field being lower than the reset start voltage of the second type sub-field; applying address data to the address electrodes during each address period while applying a scan pulse sequentially to the first electrodes causing an address discharge to occur in selected discharge cells, the scan pulse being between a scan high voltage and a scan low voltage; and applying a pulse of a sustain voltage alternately to the first electrodes and the second electrodes during each sustain-discharge period causing a sustain discharge to occur in the selected discharge cells.
