Plasma display device and plasma-display-panel driving method

摘要

In a plasma-display-panel driving method, a field period is divided into a plurality of sub fields, each of which has an address period for allowing discharge cells to selectively generate an address discharge and a sustain period for allowing the discharge cells having generated the address discharge to generate a sustain discharge by a number of times corresponding to a brightness weight. In the sustain period, a period for setting display electrode pairs to the base potential is disposed between the sustain pulse for causing the final sustain discharge in the sustain period and the previous sustain pulse. An accumulated time measuring circuit measures an accumulated time of the time when the plasma display panel is electrified, and the period for setting display electrode pairs to the base potential is changed depending on the accumulated time measured by the accumulated time measuring circuit.
