    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.

    摘要翻译： PDP驱动方法。 当在维持期间中向扫描电极施加第一维持脉冲时，寻址电极被正电压偏置，或寻址电极偏置。 因此，在寻址期间通过寻址放电在地址和扫描电极上形成大量的壁电荷时，由于在维持期间形成了寻址电极的高电位，所以不会产生主放电。

    摘要： A method for dividing a frame into a plurality of subfields, and driving them on a plasma display panel having a plurality of first electrodes and second electrodes formed in parallel on a first substrate, and a plurality of third electrodes formed on a second substrate and extending over the first and second electrodes. A first voltage and a second voltage are applied to the first electrode and the second electrode of the discharge cell to be selected from among the discharge cells during an address period of a first subfield with the minimum weight from among the subfields, such that the difference between the first voltage and the second voltage is less than a discharge firing voltage.

    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 method for driving a panel includes classifying cells on the panel into a plurality of cell groups and performing an addressing and a sustain discharge on cells included in each of the cell groups using address electrodes, scan electrodes, and common electrodes on the panel; dividing a frame period into a plurality of subfields, allocating different gray scales to the plurality of subfields, respectively, and selectively driving the subfields to represent gradation of visible brightness of the cells on the panel; and sequentially performing an address period and a sustain period on the cell groups in at least one subfield. After the address period is performed on cells included in a cell group, the sustain period is performed on the cells included in the cell group. After the sustain period is completed on one cell group, the address period is performed on another cell group. While the sustain period is performed on one cell group, the sustain period may be selectively performed on other cell groups on which the address period has been performed. Bias voltages applied to the common electrodes while the address period is sequentially performed on the cell groups are different among the cell groups.

    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.
