摘要： Stable address discharge is caused in a plasma display panel. For this purpose, the image display region of the panel is divided into a plurality of partial display regions, and scan electrodes in each partial display region are classified into two scan electrode groups based on the arranging sequence of the scan electrodes on the panel. The two scan electrode groups are a first scan electrode group including odd-numbered scan electrodes, and a second scan electrode group including even-numbered scan electrodes, In each partial display region in the address period, an overshoot address operation is performed. To the scan electrodes to which scan pulses are to be applied from the first time to a predetermined-number-th time in each scan electrode group, scan pulses are applied where the pulse cycle is set longer than that of the scan pulses to be applied to the other scan electrodes.

摘要： The plasma display apparatus suppresses addressing failure, enhancing stability of address discharge, and therefore, enhancing quality of display image on the panel. The present invention attains above through the followings: preparing display combination sets each of which having difference in number of combinations; determining whether or not magnitude of image signals, except for a predetermined color image signal, is greater than a threshold; and according to the determination above, selecting a set for the predetermined color image signal from the display combination sets. A display combination set used for the predetermined color image signal when the image signals except for the predetermined color image signal have magnitude not less than the threshold is smaller in number of combinations than that used for the predetermined color image signal when the image signals except for the predetermined color image signal have magnitude smaller than the threshold.

摘要： A scan electrode driving circuit performs an address operation by applying a scan pulse to scan electrodes in address periods. The partial light-emitting rate detecting circuit divides the plasma display panel display area into a plurality of regions, and detects a rate of the number of discharge cells to be lit with respect to the number of all the discharge cells in each region, as a partial light-emitting rate, in each subfield. The scan electrode driving circuit performs a first initializing operation in the initializing periods, and a second initializing operation in the address periods. The scan electrode driving circuit performs the address operation on the region having the highest partial light-emitting rate detected in the partial light-emitting rate detecting circuit, immediately after the first initializing operation, and on the region having the second highest partial light-emitting rate immediately after the second initializing operation.

摘要： An image display device includes a pair of sustain pulse generators for applying either a first sustain pulse or a second sustain pulse to the display electrodes. The first and second sustain pulses generate a sustain discharge twice and once, respectively, in discharge cells when the voltage applied between the display electrodes changes. The application of the first sustain pulse is performed by generating a first discharge by applying a voltage to one of the display electrodes using the clamp corresponding to the one of the display electrodes, and then generating a second discharge by applying a voltage to the other of the display electrodes using the clamp corresponding to the other of the display electrodes. The application of the second sustain pulse is performed by generating a first discharge by applying a voltage to each of the display electrodes using the clamps corresponding to each of the display electrodes.

摘要： A method for driving a plasma display panel including discharge cells at the intersections of data electrodes D1 to Dm and pairs of scan electrodes SC1 to SCn and sustain electrodes SU1 to SUn. One field period is composed of a plurality of subfields each including a writing period and a sustain period.

A voltage to be applied to sustain electrodes SU1 to SUn in the writing period of the subfield having the lowest display luminance of all the subfields is set higher than a voltage to be applied to sustain electrodes SU1 to SUn in the writing period of the subfields other than the subfield having the lowest display luminance.
