Patent ID: 7372434

Claim:
A method of driving a discharge display panel by which gray-scale display is performed on a discharge display panel, comprising: using time-division drive by including a plurality of subfields in a unit frame, wherein each of the subfields comprises: a first address period in which a predetermined wall voltage is generated in display cells selected from display cells of a first display electrode-line pair group; a first display-sustain period in which display-sustain discharge occurs 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; a second address period in which a predetermined wall voltage is generated in display cells selected from display cells of a second display electrode-line pair group when the first display-sustain period has elapsed; and a second display-sustain period in which display-sustain discharge occurs 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.
