Foregoing invention is to use in interchange (AC) the plasma display panel driving waveform interval of ramp resetting (ramp reset) about resetting interval.(Reset) interval that resets is the interval of all unit of initialization plasma display.Initialization means that all wall electric charges that produce in the former discharge process provide the same terms, make it can regular picture in the unit (OFFcell) of discharge cell (ON cell) or not discharge.Influenced by discharge in these interval all unit (cell), therefore will suppress the generation of light as far as possible in order to improve contrast (contrast).In order to suppress the generation of light in (Reset) interval that resets, the most widely used method is to utilize the fuzzy discharge reduction of voltage ramp (voltageramp) (dark discharge reset) in exchanging (AC) plasma display.With the waveform among Fig. 1 is example, reset (reset) interval by " rising edge (set-up) interval " with " negative edge (set-down)? interval " form.Voltage ramp (voltage ramp) is negative in rising edge (Setup) interval is added on the Y electrode, and X electrode and Z electrode keep 0V.The negative down-ramp that adds on the Y electrode in negative edge (Set-down) interval, the negative Vs that adds of Z electrode, the negative 0V that adds of X electrode.
Above-mentioned former ramp resetting pulse is to utilize the drive waveforms of voltage rising/dropping characteristic slowly, all is used at each son (SF) usually.But because of each son keep pulse number average difference, wall state of charge of each son after the pulsed discharge is all inequality also unified in all sons to use former reset pulse even keep, and therefore causes unnecessary time loss amount to increase.
