<p>PROBLEM TO BE SOLVED: To emit light for coordinate detection while suppressing a reduction in the contrast of a plasma display panel.SOLUTION: A plurality of sub-fields including a synchronization detection sub-field SFo generating synchronization detection discharge, a y-coordinate detection sub-field SFy generating y-coordinate detection discharge, and an x-coordinate detection sub-field SFx generating x-coordinate detection discharge constitute one field period, the synchronization detection sub-field SFo includes a write period Pw2 for applying a write pulse to a data electrode, applying a scanning pulse to a scan electrode, and generating write discharge, and a synchronization detection period Po alternately applying a synchronization detection pulse to the scan electrode and a sustaining electrode and generating the synchronization detection discharge. In the write period Pw2 of the synchronization detection sub-field SFo, the write discharge is generated by applying the write pulse only to the data electrode of each discharge cell including a phosphor layer of a predetermined color.</p> |
