摘要： Between a sustain circuit outputting a sustain pulse and a scan circuit (even) driving a Y electrode of an even display line, there is provided a first switch capable of making the Y electrode of the even display line be in a high impedance state, and between the sustain circuit and a scan circuit (odd) driving a Y electrode of an odd display line, there is provided a second switch capable of making the Y electrode of the odd display line be in the high impedance state. By first and second switches, the Y electrode of the even display line and the Y electrode of the odd display line can be independently controlled to be in the high impedance states, whereby discharge of the even display line can be restrained in a sustain period of an odd frame, while a discharge of the odd display line can be restrained in a sustain period of an even frame, thereby realizing an interlace drive without complicating a circuit configuration.

摘要： Sustain pulses are alternately applied to a pair of display electrodes of discharge cells provided in a plasma display panel (PDP) to generate a sustain discharge to display an image on the PDP. The sustain pulses include two-crests discharge voltage waveforms having a first maximum and second maximum values, in which discharges are generated twice in a half cycle. After applying a sustain pulse having a one-crest discharge voltage waveform to a pair of display electrodes, a predetermined number of sustain pulses of two-crests discharge voltage waveforms are consecutively applied. A time, from applying a second sustain pulse of a two-crests discharge voltage waveform to clamping a voltage of the second sustain pulse to the second maximum value, is made longer than a time, from applying a first sustain pulse of a two-crests discharge voltage waveform to clamping a voltage of the first sustain pulse to the second maximum value.

The method includes classifying a display ratio into plural group ranges, selecting a suitable display pulse waveform for each group range, detecting the display ratio of an object to be displayed in a real display, and plural types of display pulses having different waveforms are used differently in accordance with the result of the detection. The display ratio means a ratio of the number of cells to be lighted to the number of cells of the screen.
