Abstract
When a discharge start voltage takes a normal value under the normal temperature, priming discharge starts at a time t. In this case, at a time tthat is later than the time tby a predetermined time t, a sustain driver control signal Ssudis raised to put a sustain electrode into the floating state to stop the priming discharge. When the discharge start voltage takes a higher value than usual under the high temperature, the priming discharge starts at a time t. In this case, at a time tthat is later than the time tby the predetermined time t, the sustain driver control signal Ssudis lowered to put the sustain electrode into the floating state to stop the priming discharge. With such a configuration, provided is a plasma display device capable of implementing excellent and stable display quality while maintaining constant, even if a discharge start voltage varies, the charge state in display cells after a priming period, and a drive method for such a plasma display device.
