PLASMA DISPLAY PANEL DRIVING APPARATUS, DRIVING METHOD AND PLASMA DISPLAY DEVICE

摘要

A two-phase driving operation is performed at least in a subfield exhibiting the maximum brightness weight by applying to a plurality of first scan electrodes a first ramp waveform falling from a first potential to a second potential during an initialization interval; also applying to a plurality of second scan electrodes a second ramp waveform falling from a third potential higher than the first potential to a fourth potential higher than the second potential during the initialization interval; sequentially applying scan pulses to the plurality of first scan electrodes during a write interval; and thereafter sequentially applying scan pulses to the plurality of second scan electrodes. The application of the two-phase driving operation can prevent discharge failures from occurring in the write discharges.
