Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A plasma display device includes a plasma display panel (PDP) and a driving method for driving the PDP. The PDP includes discharge cells that are formed by scan electrodes, sustain electrodes, and address electrodes. The driving method divides a frame of the plasma display panel into a plurality of subfields having respective weights in which gray scales are represented by a combination of the subfields. The plurality of subfields are divided into a first group and a second group. In an address period of a subfield of the first having a lowest weight subfield of the plurality of subfields, the method applies a scan voltage and an address voltage respectively to the scan electrode and the address electrode of a discharge cell to be selected from the discharge cells. The scan voltage is applied to the scan electrode and the scan electrode is floated.

Abstract: A display device for displaying pictures by sequentially performing an address period and a sustain period. The panel pixels are arranged into groups, and an address period and a sustain period are sequentially performed on the pixels of individual groups. While an address period is being performed on the pixels of a group, the pixels of other groups are idle. While a sustain period is being performed on the pixels of the group subsequent to the address period, a sustain period is selectively performed on the pixels of other groups that have already undergone an address period. Accordingly, a sustain discharge operation is performed within a short time after an address operation is performed on the pixels, so that a stable sustain discharge occurs even though narrow scan pulses and address pulses may be applied during the address operation. Also, the time required to address all pixels is reduced.

Abstract: 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.
