摘要: A plasma display panel (PDP) and a method for driving the PDP. An ON/OFF pattern of an externally-inputted image signal is checked to sense a sustained discharge occurring in discharge cells respectively corresponding to scan electrodes included in a particular one of multiple scan electrode groups over a predetermined time. A control operation is carried out in response to the sensing of the sustained discharge to allow a discharge to occur in discharge cells respectively corresponding to scan electrodes included in the scan electrode groups other than the particular scan electrode group.

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 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.

摘要: In a method of driving a discharge display panel, each subfield may include a first address period, a first display-sustain period, a second address period, and a second display-sustain period. In the first address period, a predetermined wall voltage may be generated in display cells selected from the display cells of the first display electrode-line pair group. In the first display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first display electrode-line pair group when the first address period has elapsed. In the second address period, a predetermined wall voltage may be generated in display cells selected from the display cells of the second display electrode-line pair group when the first display-sustain period has elapsed. In the second display-sustain period, display-sustain discharge may occur during a time proportional to a gray scale weight of each of the subfields in the selected display cells of the display cells of the first and second display electrode-line pair groups when the second address period has elapsed.

摘要: A PDP driving method. When a first sustain pulse is applied to a scan electrode during a sustain period, an address electrode is biased by a positive voltage, or the address electrode is biased. Therefore, when a large amount of wall charges are formed on the address and scan electrodes by address discharging during an address period, no main discharge is generated since a high potential of the address electrode is formed in the sustain period.
