摘要： The present invention provides a method of driving a plasma display apparatus, which allows a high-luminance large-sized panel to have stable address discharge, with increase in power consumption suppressed. In the method, one field is divided into a plurality of subfields, each of which having an address period and a sustain period. A ramp voltage is applied to the scan electrodes in the end of the sustain period. The ramp voltage increases from a base potential toward a predetermined voltage, after reaching the predetermined voltage, the ramp voltage is maintained at the voltage for a predetermined period of time and decreases to the base potential. Besides, when the number of the sustain pulses is not greater than a predetermined threshold in a subfield, the predetermined period of time of an immediately after subfield is determined to be longer than the predetermined period of time of other subfields.

摘要： A stable address discharge is caused by preventing an increase in the scan pulse voltage (amplitude) necessary for causing a stable address discharge, and thereby achieves high image display quality. For this purpose, the following operations are performed. The image display area of a plasma display panel is divided into a plurality of regions. In each region, the rate of the number of discharge cells to be lit with respect to the number of all discharge cells in each region is detected, as a partial light-emitting rate of each region, and the partial light-emitting rate is detected in each subfield. The region having the maximum partial light-emitting rate is detected and set as a first region. The regions adjacent to the first region are set as second regions, and a predetermined offset value is added to the partial light-emitting rates of the second regions so as to provide corrected partial light-emitting rates. Magnitude comparison is performed between the partial light-emitting rates and corrected partial light-emitting rates, and the order of address operations on the respective regions is determined based on the result of the magnitude comparison.

摘要： A stable address discharge is caused by preventing an increase in the necessary scan pulse voltage (amplitude), and thereby achieves high image display quality. For this purpose, the image display area of a plasma display panel is divided into a plurality of regions, and a partial light-emitting rate is detected in each region. The partial light-emitting rate in a current subfield is set as a first partial light-emitting rate. The partial light-emitting rate used for magnitude comparison between the partial light-emitting rates in a subfield identical with the current subfield in a field immediately preceding the field to which the current subfield belongs to is set as a second partial light-emitting rate. The absolute value of the difference between the first partial light-emitting rate and the second partial light-emitting rate is calculated in each region. In the region where the value is equal to or larger than a light-emitting rate threshold value, the first partial light-emitting rate is used for the magnitude comparison between the partial light-emitting rates in the current subfield. In the region where the value is smaller than the light-emitting rate threshold value, the second partial light-emitting rate is used for the magnitude comparison between the partial light-emitting rates in the current subfield.
