Abstract:
A method of driving a plasma display panel, which is a mixed scan-sustain-type plasma display panel for displaying a desired image by carrying out each of set-up discharge, set-up discharge erase, write discharge, sustain discharge, and sustain discharge erase for each scan line of an AC type plasma display panel that is made up of a plurality of display cells arranged in a lattice; said method comprising:carrying out said write discharge to said display cells, selectively, by both sequentially applying scan pulses to scan electrodes of said scan lines and applying data pulses to prescribed data electrodes; and carrying out said set-up discharge by applying a first set-up discharge pulse, that is a gradually rising pulse of polarity opposite to said scan pulse, to scan electrodes of the next scan line to be scanned; and applying a second set-up discharge pulse, that is a rectangular pulse of lower absolute voltage value than said scan pulse, and moreover, of the same polarity as said scan pulse, to the sustain electrodes of the next scan line to be scanned; wherein an absolute value of the potential difference between a potential of said second set-up discharge pulse and a potential of said data pulse is lower than a discharge threshold voltage between a sustain electrode and a data electrode.
