摘要： In a method of driving an AC plasma display panel of the present invention, one field period is made of a plurality of sub-fields (SFs), each including an initializing period, writing period, and sustaining period, and a part of sustaining operation in the sustaining period in at least one of the plurality of SFs and a part of selective initializing operation in the initializing period in a SF following the at least one SF are performed at the same time. The method comprises making a pulse width of a top sustain pulse in one of the sustaining periods in the plurality of SFs different from that in another of the sustaining periods therein. This method limits the SFs in which any erroneous discharge occurs to lower order of SFs and can inhibit the brightness of the erroneous discharge.

摘要： A driving method of plasma display panels is disclosed. This method can suppress a dark belt occurring in displaying a video of a lower part of grayscale. One field includes plural sub-fields, and each one of the sub-fields has an addressing period during which a scan pulse is applied to the scan electrodes and a data pulse is applied to the data electrodes, and a sustaining period during which a sustain pulse is applied to the scan electrodes and the sustain electrodes. A time interval between a scan pulse applied lastly during the addressing period and a sustain pulse applied firstly during the sustaining period is defined as a last pulse-interval. The last pulse-interval of at least one sub-field of a lower part of grayscale, which lower part is darker than a predetermined level of the grayscale, is set longer than the last pulse-intervals of the other sub-fields.
