ABSTRACT:
A method for driving a plasma display panel is provided in which a wall voltage at an interelectrode between a display electrode and an address electrode is controlled without increasing contrast in preparation for addressing, so that reliability of addressing is improved. As an operation of initialization for controlling the wall voltage of a cell within a screen as a preparation for the addressing, a first blunt wave application is performed for generating discharge only in a previous non-lighted cell that was not lighted in a previous display, and a second blunt wave application is performed for generating discharge in each of the previous non-lighted cell and a previous lighted cell that was lighted in the previous display.
