METHOD FOR DRIVING PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE

摘要

In order to stabilize a writing discharge in a plasma display device and to heighten image display quality by heightening contrast, a discharge cell for performing a forced initialization operation in the initialization period of a subfield immediately following a weak-discharge-sustaining subfield applies a first upwardly inclined waveform voltage to a scanning electrode during the sustain period of a weak-discharge-sustaining subfield and then applies a voltage at which no discharge occurs to the scanning electrode. In a discharge cell for performing a selective initialization operation in the initialization period of a subfield immediately following a weak-discharge-sustaining subfield, a second upwardly inclined wavelength voltage is applied to the scanning electrode after the first upwardly inclined wavelength voltage is generated in the sustain period of the weak-discharge-sustaining subfield.
