摘要： A plasma display includes a plurality of scan electrodes. A scan voltage is sequentially supplied to the plurality of scan electrodes, and a non-scan voltage that is higher than the scan voltage is supplied to scan electrodes to which the scan voltage is supplied. The non-scan voltage is generated by dividing a voltage that is higher than the non-scan voltage and the scan voltage. Thus, a voltage source for supplying the non-scan voltage can be eliminated.

摘要： Positive and negative sustain discharge voltages of equal magnitude are alternately applied to a scan electrode while biasing the sustain electrode at 0 V during a sustain interval. The positive sustain discharge voltage is applied through the first end of the scan electrode, and the negative sustain discharge voltage is applied through the second end of the scan electrode. The present invention may remove a brightness variation which may occur toward a direction the scanning electrode extends.

摘要： In a plasma display panel driving method, a final voltage of a falling ramp voltage is reduced to a voltage for firing a discharge at all the discharge cells in a reset period. A difference between a voltage at an address electrode of a discharge cell to be selected and a voltage applied to a scan electrode is established to be greater than a maximum discharge firing voltage in an address period. A voltage greater than a sustain voltage is applied to the scan electrode so as to convert positive wall charges which can be formed on the scan electrode of a discharge cell which is not selected in the address period into negative wall charges.

摘要： A PDP driving method. A falling ramp voltage is applied to a scan electrode so as to reset a state of wall charges of a discharge cell during a reset period. In this instance, a sustain electrode is maintained at a high voltage during an initial period for applying the falling ramp voltage, and the voltage at the sustain electrode is reduced to a normal voltage at a latter part of the period for applying the falling ramp voltage. Accordingly, the voltage applied to an address electrode is reduced in an address period since an erased amount of the wall charges of the address electrode is reduced during the reset period.
