A second ramp waveform dropping from a third potential (Vi3) to a fourth potential (Vi4) is applied to the plurality of scan electrodes (SC) in the second half period following the first half period, and a fourth ramp waveform dropping from a seventh potential (Ve) to an eighth potential (Vi6, Vi6′) is applied to the plurality of sustain electrodes (SU) in a period, which is shorter than the second half period, within the second half period. Then, a peak value of the third ramp waveform and a peak value of the fourth ramp waveform are changed based on a state of a plasma display panel.

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： In displaying a predetermined image on a plasma display panel, occurrence of an initializing bright point can be suppressed to reduce the maximum voltage in an all-cell initializing operation, light emission in the all-cell initializing operation is suppressed to reduce the black luminance, and the contrast is sharpened. In driving the plasma display panel, one field period includes a plurality of subfields having a setup period for causing initializing discharge in discharge cells, an address period, and a sustain period. One field period includes at least one subfield for applying ramp waveform voltage increasing in the setup period to the scan electrodes. The maximum voltage of the ramp waveform voltage can be varied. When a predetermined image establishing a previously determined condition is displayed, the ramp waveform voltage is generated whose maximum voltage is smaller than when an image other than the predetermined image is displayed, and a positive voltage is applied to the data electrodes at least while the ramp waveform voltage having the smaller maximum voltage is applied to the scan electrodes.

摘要： An image display method for allowing an image display device having a large number of pixels arrayed in a planar form to perform an image display by forming one field period from plural sub-fields for which luminance weights to be displayed are determined, and choosing plural luminances among displayable luminances as luminances for display by combining the luminance weights of the sub-fields, so that the respective pixels are controlled not to emit light or to emit light in each sub-field correspondingly to the luminances for display to be displayed. At least one threshold value is set, and when a pixel is allowed to emit light at a luminance for display at or higher than a first threshold value, which is the smallest threshold value, the pixel is controlled not to emit light constantly or to emit light constantly in a sub-field having the smallest luminance weight.

摘要： Disclosed here is a method for driving a plasma display panel and a plasma display device capable of providing image display with a high contrast ratio and excellent quality by stabilizing an address discharge. According to the method, which is the method for driving a plasma display panel in which discharge cells are formed at intersections of scan electrodes, sustain electrodes and data electrodes, the field—that contains at least one sub-field having the all-cell initializing operation—and the field—that is formed of sub-fields having the selective-cell initializing operation only—are set at a ratio of 1:N (where, N takes an integer of 1 or greater). At the same time, at least in one sub-field of the field having the selective-cell initializing operation only, the scan-pulse width employed for the selective-cell initializing field is determined longer than the scan-pulse width employed for the field containing the all-cell initializing operation.
