Abstract: A brightness modulation system for a plasma display panel device in which one picture element is made up of a plurality of discharge cells, the brightness levels of the plurality of discharge cells are made different from each other by impression of voltages of different phases or repetitive frequencies and the discharge cells are selectively combined, thereby to achieve a display composed of a plurality of graded tones.
