METHOD OF DRIVING PLASMA DISPLAY DEVICE AND PLASMA DISPLAY DEVICE

WIPO Patent Application WO/2012/073516

A1

The present invention improves contrast and stably produces a write discharge in a plasma display device. In order to do that, during an initialization period an initialization operation is performed which is either a forced initialization operation that produces an initialization discharge in a discharge cell, or a selective initialization operation that selectively produces an initialization discharge in a discharge cell producing a write discharge in the last subfield. A specific cell initialization subfield which performs a forced initialization operation in one specific discharge cell and performs a selective initialization operation in other discharge cells, and a selective initialization subfield which performs a selective initialization operation in all the discharge cells, are provided within one field. During a selective initialization period, a descending gradient waveform voltage is applied to a scanning electrode and a positive voltage is applied to a data electrode. In the selective initialization subfield, the minimum voltage of the descending gradient waveform voltage is controlled on the basis of the load when the data electrode is driven which is calculated during the write period of the last subfield.
