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： 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： A stable address discharge is generated to achieve a high quality of image display. For this purpose, a plasma display panel, a scan electrode driving circuit, and a partial light-emitting rate detecting circuit are provided. The scan electrode driving circuit performs an address operation by sequentially applying a scan pulse to scan electrodes in an address period. The partial light-emitting rate detecting circuit divides the display area of the plasma display panel into a plurality of regions, and detects a rate of the number of discharge cells to be lit with respect to the number of discharge cells, as a partial light-emitting rate, in each of the regions. The scan electrode driving circuit performs the address operation earlier on the regions having the higher light-emitting rates detected in the partial light-emitting rate detecting circuit in decreasing order of value.

摘要： Any of first and second sub-field configurations is selected. In the first sub-field configuration, a width of a write pulse of a sub-field with a lowest display luminance is not more than widths of write pulses of the other sub-fields. In the second sub-field configuration, the width of the write pulse of the sub-field with the lowest display luminance is larger than the widths of the write pulses of the other sub-fields. When the first sub-field configuration is selected, a voltage applied to a sustain electrode in a write period of the sub-field with the lowest display luminance is set higher than a voltage applied to the sustain electrode in write periods of the other sub-fields. When the second sub-field configuration is selected, the voltage applied to the sustain electrode in the write period of the sub-field with the lowest display luminance is set to be the same as the voltage applied to the sustain electrode in the write period of any of the other sub-fields.

摘要： One field period includes a plurality of subfields each having an initialization period in which a gradually descending sloping waveform voltage is applied to a scan electrode, a writing period in which a negative scan pulse voltage is applied to the scan electrode, and a sustain period. A sloping waveform voltage is generated by switching a minimum voltage in the sloping waveform voltage between a first voltage and a second voltage that has a lower voltage value than that of the first voltage. The ratio in one field period of a subfield in which an initialization is carried out by the sloping waveform voltage whose minimum voltage is the second voltage is increased when a temperature of the plasma display panel is determined to be low as compared with when the temperature is determined to be not low.
