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.
