ABSTRACT:
A method for driving a matrix type of plasma display panel is capable of stably displaying an image in error-discharge free. The plasma display panel including a plurality of row electrodes extending parallel to each other, two adjacent ones of the row electrodes being paired, and a plurality of column electrodes extending perpendicularly to the row electrodes at a given intervals wherein a region in which, one pair of row electrodes and one column electrode are crossed and spaced with a distance to each other at an intersection corresponding to one pixel. The method includes the steps of: applying first resetting pulses to all of the row electrodes simultaneously to cause discharges between all of the pairs of row electrodes, each first resetting pulse including a pulse rise or pulse fall time longer than each duration of the sustain pulse for sustaining a discharge emission as a simultaneous resetting step; applying a second resetting pulse to one of the pair of row electrodes to cause discharge therebetween immediately after applying the first resetting pulse to the one of the pair of row electrodes; applying a scan pulse to every pair of row electrodes and simultaneously applying a pixel data pulse to every column electrode to write pixel data to the associated pixels in accordance with pixel data pulses applied; and applying a series of sustain pulses alternately to one of the row electrode pair and the other thereof to maintain sustain-discharge between the pair of row electrodes.
