PLASMA DISPLAY DEVICE AND METHOD FOR DRIVING PLASMA DISPLAY PANEL |
摘要 |
<p>In a plasma display device and a method for driving a plasma display panel, fluctuation of emission luminance of a discharge cell is reduced and display quality of an image is improved. The plasma display device is provided with a plasma display panel having a plurality of scanning electrodes and sustaining electrodes which configure a display electrode pair. The plasma display device is also provided with a sustaining pulse generating circuit, which has a plurality of subfields having an initializing period, a writing period and a sustaining period in one field period, and generates three kinds of sustaining pulses, i.e., a first sustaining pulse to be reference, a second sustaining pulse whose start-up is sharper than that of the first sustaining pulse and that of a third sustaining pulse, and the third sustaining pulse whose trailing edge is sharper than that of the first sustaining pulse and that of the second sustaining pulse, by periodically switching the pulses. In a sustaining period of at least one subfield in one field period, the third sustaining pulse is applied to one electrode of the electrode pair, then just after the application, the second sustaining pulse is applied to the other electrode of the display electrode pair.</p> |
