PLASMA DISPLAY AND DRIVING METHOD OF DRIVING PLASMA DISPLAY PANEL |
摘要 |
A plasma display which can generate stabilized write discharge stably without raising a voltage required for generating the write discharge. The plasma display comprises a plasma display panel equipped with a plurality of discharge cells having a plurality of scan electrodes constituting a display electrode pair and a sustentation electrode, and a circuit for driving each electrode by providing, in one field period, a plurality of subfields each having an initialization period, a write period and a sustentation period. A period for holding both electrodes of the display electrode pair at a base potential is provided between the last sustentation pulse and the immediately preceding sustentation pulse in a sustentation period depending on the lighting rate of the discharge cell in that subfield. With a time lag provided dependent on the lighting rate of the discharge cell in that subfield after a voltage for generating the last sustentation discharge is applied to the display electrode pair, a voltage is applied to the display electrode pair such that the potential difference between the electrodes of the display electrode pair is reduced.
