20120154357 | METHOD FOR DRIVING A GAS ELECTRIC DISCHARGE DEVICE - A method for driving a plasma display panel having at least three electrodes. The method includes applying a first pulse having a voltage changing with time in a positive direction and a second pulse having a voltage changing with time in a negative direction to a second main electrode in an address preparation period. The method also includes applying a scan pulse to the second main electrode in an address period. The method also includes at least one of the first and second pulses in the address preparation period has a stepwise waveform whose voltage rise or fall stepwise. | 06-21-2012 |
20090251444 | Method for driving a gas electric discharge device - A method for driving a plasma display panel having at least first electrodes and second electrodes which cause discharge in cells is provided. The method includes applying a first pulse and a second pulse to the second electrode in an address preparation period. The method also includes applying a scan pulse to the second pulse to the second electrode in an address period. The method includes the first pulse having a voltage changing with time in a positive direction and the second pulse having a voltage changing with time in a negative direction and the scan pulse having a negative voltage which is lower than the attained voltage of the second pulse. | 10-08-2009 |
