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: PROBLEM TO BE SOLVED: To improve contrast in a plasma display apparatus.
SOLUTION: The plasma display apparatus executes display on the plasma display panel, by constituting one field among a plurality of sub-fields. Each sub-field includes an address period for generating address discharge for selecting a discharge cell caused to emit a light, and a maintaining period for generating maintaining discharge by means of the discharge cell selected during this address period. The apparatus includes at least one first field F1, in which an all-cell initializing pulse is generated in all the discharge cells at the heads of lines, at least one second field F2 in which the all-cell initializing pulse is generated in the sub-fields other than those at the heads of the lines; and at least one third field F3, in which the all-cell initializing pulse, is applied to where sub-fields do not exist.

Abstract: PROBLEM TO BE SOLVED: To improve product quality of a plasma display device by improving detection precision of an initial failure in a manufacturing process.
SOLUTION: A driving circuit has a normal driving mode and an aging driving mode. In the aging driving mode, a subfield number in 1 field period is made smaller than the subfield number in 1 field period in the normal driving mode, and a length of a writing period is made longer than the writing period in the normal driving mode. In the writing period, writing pulses are applied alternately to data electrodes, so that the data electrode to which the writing pulse is applied and the data electrode to which the writing pulse is not applied become mutually neighbored. The writing pulse is continuously applied to the data electrode to which the writing pulse is applied during the writing period, and during a maintenance period, the number of generated maintenance pulses is made smaller than that during the maintenance period of the normal driving mode.

Abstract: PROBLEM TO BE SOLVED: To improve a contrast of a plasma display panel.SOLUTION: The method for driving a plasma display panel includes: a first mode in which a display is performed by applying sustain pulses of the number according to a luminance weight of a plurality of sub-fields constituting one-field period; a second mode in which the one-field period is constituted of sub-fields less than those in the first mode and a display is performed by setting the number of sustain pulses that are applied in the one-field period, to be more than the number of the sustain pulses in the one-field period in the first mode; and a third mode in which a writing time of a non-lighting line in the second mode is shortened and a display is performed by setting the shortened time to the sustain time. When a lighting rate of the sub-fields is a prescribed value or less, the gradation of an image is a prescribed value or more, and the number of lighting lines of each sub-field is the set line number or less, the contrast of a PSDP panel can be improved by shifting from the first mode or the second mode to the third mode.
