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： 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.

摘要： In a plasma display apparatus, contrast is enhanced and a stable address discharge is caused. For this purpose, one of a forced initializing operation and a selective initializing operation is performed in initializing periods. A specified-cell initializing subfield and a selective initializing subfield are set in one field. In the specified-cell initializing subfield, the forced initializing operation is performed on specified discharge cells and the selective initializing operation is performed on the other discharge cells. In the selective initializing subfield, the selective initializing operation is performed on all the discharge cells. In the selective initializing period, a down-ramp waveform voltage is applied to the scan electrodes and a positive voltage is applied to the data electrodes. In the selective initializing subfield, based on the load calculated in the address period of the immediately preceding subfield, the minimum voltage of the down-ramp waveform voltage is controlled.

摘要： Image display quality in the plasma display apparatus can be enhanced by allowing a stable address operation. For this purpose, the plasma display apparatus includes a scan electrode driver circuit. The scan electrode driver circuit generates driving voltages to be used in a subfield method and applies the driving voltages to scan electrodes. At the end of each sustain period, the scan electrode driver circuit performs the following operation. The scan electrodes are applied with a first ramp waveform voltage that rises from a base electric potential to a first electric potential. Subsequently, the electric potential of the scan electrodes is set to a second electric potential equal to or lower than the first electric potential. Subsequently, the scan electrodes are applied with a second ramp waveform voltage that rises from the second electric potential to a third electric potential higher than the first electric potential.

摘要： Sharp contrast is achieved while the driving time in displaying a 3D image on a plasma display panel is shorted. For this purpose, an all-cell initializing subfield for applying up-ramp waveform voltage and down-ramp waveform voltage to a scan electrode in the initializing period is set as the first subfield of one field. The plasma display panel is driven by one of 3D drive and 2D drive. A gradient of at least one of the up-ramp waveform voltage and the down-ramp waveform voltage in the all-cell initializing period during the 3D drive is set to be steeper than a gradient of the one waveform voltage in the all-cell initializing period during the 2D drive. A shutter opening/closing timing signal is generated so that both of a right-eye timing signal and a left-eye timing signal are in the OFF state in the all-cell initializing period during the 3D drive.
