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.

摘要： An address period is shortened while degradation of image display quality of a plasma display apparatus is suppressed. For this purpose, in a driving method for a plasma display apparatus including a plasma display panel with a plurality of discharge cells having a scan electrode, a sustain electrode, and a data electrode, and a driver circuit, the following operation is performed. The driver circuit forms one field period by a subfield that displays an interlace signal as an image signal thinned out every one line and a subfield that displays oblique line interpolated data generated by interpolating oblique lines detected by an image signal. In the subfield displaying an image signal, the driver circuit performs two-line simultaneous address operation with application of a scan pulse simultaneously to two adjacent scan electrodes so as to generate an address discharge in a discharge cell.
