Abstract:
1. A method of driving a plasma display panel comprising a first electrode, a second electrode, and discharge cells defined by the first electrode and the second electrode, the method comprising: gradually increasing a voltage of the first electrode from a first voltage to a second voltage in a reset period of a first subfield; gradually decreasing the voltage of the first electrode from a third voltage to a fourth voltage in the reset period of the first subfield; selecting a first turn-on cell among the discharge cells in an address period of the first subfield; gradually increasing the voltage of the first electrode from a fifth voltage to a sixth voltage at a first slope to discharge the first turn-on cell in a sustain period of the first subfield, a magnitude of the sixth voltage being less than a magnitude of the second voltage; and decreasing the voltage of the first electrode from the sixth voltage to the fifth voltage at a second slope after increasing the voltage of the first electrode from the fifth voltage to the sixth voltage, an absolute value of the second slope being greater than that of the first slope.
