Abstract:
1. A driving method for a plasma display apparatus having address electrodes, scan electrodes and common electrodes forming display cells and display one field of image by using a plurality of subfields, the driving method comprising: applying a reset pulse to adjust charges in the cells in a reset period; applying an address pulse to an address electrode and a scan pulse to a scan electrode in a cell to be lit during a sustain period in accordance with display data to generate an address discharge in an address period; applying sustain pulses to the scan electrodes and the common electrodes, alternately, to generate a sustain discharge in sustain period, wherein the address pulse is always applied to the address electrode in at least one specific subfield of the plurality of subfields for turning ON the specific subfield when the display data does not show a black image, the specific subfield has a least luminance weight among the plurality of subfields, the specific subfield does not have the reset period, and the subfield subsequent to the specific subfield having the reset period; and wherein a plurality of the specific subfields are provided, and the plurality of the specific subfields are arranged as a first subfield and a second subfield.
