Abstract: Crosstalk between adjacent discharge cells is reduced for a stable sustain discharge. A plasma display panel has scan electrodes and sustain electrodes arranged so that the positions of the corresponding scan electrode and sustain electrode are alternately interchanged in each display electrode pair, and image signal processing circuit converts an image signal into image data indicating light emission and no light emission in each discharge cell in each subfield. The image signal processing circuit generates the image data so that a combination of image data is avoided. One of two adjacent discharge cells having side-by-side scan electrodes is lit and the other of the discharge cells is unlit in one subfield of a plurality of subfields forming one field, and the one of the discharge cells is unlit and the other of the discharge cells is lit in a subfield after the one subfield in the same field.

Abstract: One field period includes a plurality of subfields each having (i) an initialization period in which a gradually descending sloping waveform voltage is applied to a scan electrode, (ii) a writing period in which a negative scan pulse voltage is applied to the scan electrode, and (iii) 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. A number of subfields, in which an initialization is carried out by the sloping waveform voltage having the minimum voltage as the second voltage, is increased when a temperature of a plasma display panel is determined to be low as compared with when the temperature is determined to be not low.

Abstract: Crosstalk is reduced to provide a high quality of image display when displaying a stereoscopic image on a plasma display panel. For this purpose, there is provided a method for driving a plasma display apparatus which displays the image on the plasma display panel, by alternately repeating a field for right-eye displaying an image signal for right-eye and a field for left-eye displaying an image signal for left-eye. The method is such that, in a first field and a temporally consecutive second field, for a discharge cell where a gradation displayed in the occurring-temporally-later second field is not larger than a predetermined comparison value, when displaying a gradation not smaller than a predetermined threshold in the occurring-temporally-earlier first field, image data are set where address operation is prohibited in a last subfield of the first field.

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.

The first subfield of the second subfield group has a luminance weight smaller than that of the last subfield of the first subfield group. When a gradation having a level greater than a gradation threshold is displayed, the first subfield of the second subfield group has no light emission.
