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. A voltage is applied to the first electrode and the second electrode to establish a difference between the first electrode and the second electrode to be alternately a sixth voltage and a negative voltage of the sixth voltage, and therefore the cell is discharged.

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.

摘要： A plasma display panel. Delay circuits are added to a control terminal of a switch and a rising delay time is established to be different from a falling delay time in an address driving circuit so that voltages at adjacent address electrode may not be concurrently changed in the opposite directions. Accordingly, power consumption by the address driving circuit is minimized without a power recovery circuit.
