Abstract: The plasma display device has a sustain pulse generating circuit for generating sustain pulses in a sustain period. The sustain pulse generating circuit generates at least two kinds of sustain pulses of different rising gradients in the sustain period, generates a predetermined number of sustain pulse whose rising gradient becomes steeper to the latter half in at least one-side electrode in the sustain period after first two sustain pulses and except an erasing pulse, and continuously generates the sustain pulses while the rising gradient of the sustain pulses is varied in response to the light emitting rate of the plasma display panel in the sustain period.

Abstract: Provided is a plasma display panel driving method by which display qualities of an image is improved by estimating the highest possible temperature and the lowest possible temperature of a panel based on a temperature detected by a temperature sensor and by performing suitable drive. A plasma display device is also provided. The method has at least three drive modes having different sub-field configurations, i.e., low temperature drive mode, room temperature drive mode and high temperature drive mode. The highest possible temperature and the lowest possible temperature of the panel are estimated from the temperature detected by the temperature sensor, the panel temperature status is judged from the highest possible temperature or the lowest possible temperature, and the panel is driven by switching the mode to a suitable drive mode, corresponding to the temperature status of the panel.
