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： 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.

摘要： An initialization and driving method for a plasma display panel. When the plasma display panel is turned on, a voltage at a first electrode is increased from a first voltage to a second voltage, and a voltage at a second electrode is reduced from a fourth voltage to the fifth voltage for the purpose of forming wall charges in cells while a third voltage is applied to the second electrode.

摘要： In a plasma display, image data are mapped on N subfields, and the subfield with the greatest weight is determined from among the mapped subfields. When the subfield with the greatest weight is the Kth subfield (K>M), grayscales of the image data are expressed with the mapped data of the (K−M+1)th subfield to the Kth subfield, and the mapped data from the first subfield to the (K−M)th subfield may be ignored.
