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： 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： It is an object to provide a driving method of a plasma display panel, whereby a dark contrast can be improved while suppressing an erroneous discharge. In a resetting step in a first unit display period, while a first reset pulse having a predetermined peak electric potential is applied to one of first row electrodes of row electrode pairs formed in the PDP, a second reset pulse having a peak electric potential smaller than that of the first reset pulse is applied to the other of the first row electrodes. In the resetting step in a second unit display period subsequent to the first unit display period, a second reset pulse is applied to each of the one and the other of the first row electrodes.
