Abstract:
1. A method of driving a plasma display panel, in which a plurality of first and second electrodes are provided, adjacent to each other, a plurality of third electrodes are provided to cross the first and second electrodes, and discharge cells defined by areas in which the electrodes cross mutually are arranged in a form of matrix, the method of driving having at least a reset period and an address period, wherein in the address period, a negative polarity scan pulse whose voltage is lower than a negative reference potential is applied to the second electrode, the negative reference potential being a non-selected potential, and a potential of the negative polarity scan pulse being a selected potential, and, the method of driving comprising: applying a first pulse to the second electrodes in a reset period, an applied voltage of the first pulse varying with time until reaching a first positive potential, and applying a second pulse to the second electrodes in the reset period after the first pulse is applied, an applied voltage of the second pulse varying with time until reaching a negative potential, wherein the second pulse is applied after the first pulse has fallen to a predetermined potential and the second pulse reaches a potential higher than the selected potential, which is applied to a selected second electrode being selected by the negative polarity scan pulse among the second electrodes in the address period, but lower than the non-selected potential, which is applied to the second electrodes other than the selected second electrode in the address period.
