Abstract: A subfield lighting rate measuring unit detects a lighting rate for each subfield, and a subfield processor controls a scan driver and a sustain driver so that a recovery time of each sustain pulse, a resonance time of LC resonance and a sustain period become longer as the detected lighting rate for each subfield becomes smaller.

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.

Abstract: A method for driving a plasma display panel including discharge cells formed at the intersections of the scan electrodes, maintaining electrodes, and data electrodes. One field consists of a plurality of sub fields, each having an initialization period, a write period, and a maintaining period. The maintaining period of at least one sub field has a first maintaining period during which the maintaining pulse has a first rise time and a second maintaining period during which the maintaining pulse has a second rise time shorter than the first rise time. The second maintaining period includes at least the final period of the maintaining period.
