摘要： A stable address discharge is generated to achieve a high quality of image display. For this purpose, a plasma display panel, a scan electrode driving circuit, and a partial light-emitting rate detecting circuit are provided. The scan electrode driving circuit performs an address operation by sequentially applying a scan pulse to scan electrodes in an address period. The partial light-emitting rate detecting circuit divides the display area of the plasma display panel into a plurality of regions, and detects a rate of the number of discharge cells to be lit with respect to the number of discharge cells, as a partial light-emitting rate, in each of the regions. The scan electrode driving circuit performs the address operation earlier on the regions having the higher light-emitting rates detected in the partial light-emitting rate detecting circuit in decreasing order of value.

摘要： In a setup period of a first SF, a first ramp waveform (L2) that drops from a first potential (Vsus) to a second potential (−Vad+Vset2) is applied to scan electrodes belonging to a first scan electrode group.
