ABSTRACT:
In a method of driving a discharge display panel, each subfield may include a first address period, a first display-sustain period, a second address period, and a second display-sustain period. In the first address period, a predetermined wall voltage may be generated in display cells selected from the display cells of the first display electrode-line pair group. In the first display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first display electrode-line pair group when the first address period has elapsed. In the second address period, a predetermined wall voltage may be generated in display cells selected from the display cells of the second display electrode-line pair group when the first display-sustain period has elapsed. In the second display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first and second display electrode-line pair groups when the second address period has elapsed.
