摘要： A PDP driving method. No rising ramp voltage is applied to a scan electrode during a reset period. The final voltage of a falling ramp voltage is reduced to a voltage by which all the discharge cells can fire the discharge during the reset period. A difference between the voltage applied to the address electrode of the discharge cell to be selected and the voltage applied to the scan electrode is established to be greater than the maximum discharge firing voltage.

摘要： A panel capacitor is formed by a scan electrode and a sustain electrode. The voltage at the panel capacitor is reduced by turning on a transistor coupled between the scan electrode and the capacitor. As a result, the voltage within the panel capacitor exceeds the discharge firing voltage to discharge the panel capacitor. When the gate voltage of the transistor is reduced by an RC circuit, the transistor is turned off, and the scan electrode is floated. A discharge is then steeply quenched, and wall charges are finely controlled. Next, the above-noted operation is repeated by turning on the transistor.

摘要： A plasma display panel (PDP) and driving method that includes a floating reset process. A number of subfields are generated from input video signals, and subfield data for each subfield are output. A first voltage is applied to the first electrode according to sustain information to cause a discharge in a first discharge space, and the first electrode is floated during a period which corresponds to subfield data of a previous subfield. During this process, the floating time is controlled according to the number of addressed cells called for in previous subfield data.

摘要： A driving apparatus of a plasma display panel. In a scan electrode driving circuit, a drain of a first transistor is coupled to a scan electrode, and a driver of the first transistor is coupled to the gate and a source of the first transistor. During a reset period, the driver turns on the first transistor and reduces a voltage at a scan electrode and then turns off the first transistor so as to gradually reduce the voltage of the scan electrode by floating the scan electrode. Further, a selecting voltage may be applied to the scan electrode by turning on the first and second transistors during an address period. Thus, the transistor used during the reset period may be used in the address period.
