摘要： The present invention aims to improve a low gradation expression ability by reducing the brightness of the 1st gradation level to about 1.05 cd/m2 of the intermediate brightness between the 0th gradation level and the 2nd gradation level at the time of driving a PDP. During a sustain erase period (P13) of a subfield (SF1) with the smallest brightness weight among a plurality of subfields (SF), a positive voltage (Vbk) that is smaller than a voltage (Vsus) applied during a sustain period (P23) of other SFs is applied to scan electrodes. Also, during the sustain erase period (P13) of SF1, a positive voltage (Vda) is applied to address electrodes or a positive voltage (Vda) is applied to the address electrodes during at least one period of a voltage rising period (T11) of an all-cell reset period (P11).

摘要： A method of driving a plasma display panel having display electrode pairs each one of which pairs is formed of a scan electrode and a sustain electrode. A priming electrode is placed in every other spaces between the display electrode pairs and in parallel with the display electrode pairs.

During the respective addressing periods, scan pulse voltage Va is applied to odd-number scan electrodes or even-number scan electrodes while priming pulse voltage Vp is applied, prior to the application of the scan pulse voltage, to a priming electrode adjacent to the scan electrode to which scan pulse voltage Va is to be applied, in order to generate a priming discharge between the priming electrodes and the data electrodes.

摘要： Barrier ribs are disposed on a back substrate so as to separate main discharge cells formed of a display electrode pair and a data electrode which face each other and priming discharge cells formed of a clearance between two adjacent scan electrodes. The top parts of the barrier ribs are formed so as to abut on a front substrate.

In an even-numbered line writing time period, scan pulse Va is sequentially applied to even-numbered scan electrode SCp+1 and voltage Vq is applied to odd-numbered scan electrode SCp to cause priming discharge between scan electrode SCp and even-numbered scan electrode SCp+1.
