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.

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： A method for driving a display panel to produce an efficient sustain discharge is provided. In one embodiment, the display panel includes a plurality of scanning electrodes that are driven by a sustain discharge signal. A corresponding plurality of common electrode groups is driven individually by different sustain discharge signals. Sustain discharge is performed by alternately applying high level sustain pulses to each the plurality of scanning electrodes and each the plurality of common electrode groups. Sustain pulses with a high level are applied sequentially to each the plurality of common electrode groups in time intervals between the sustain pulses with the high level applied to the plurality of scanning electrodes. Therefore, it is possible to maintain a duty rate of a sustain discharge signal near 50% while reducing a peak value of currents generated upon sustain discharge driving, thereby achieving stable sustain discharge.

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.
