PLASMA DISPLAY DEVICE |
摘要 |
<p>In a plasma display device, a lighting rate is calculated from a video signal input in a plasma display device, and an output current of DC-DC converter (140), which is the same as a discharge current in a sustain period corresponding to the lighting rate, is synchronized with a generation timing of discharge current. With such a configuration, even if discharge current in the sustain period of each subfield is rapidly changed, a sustain pulse voltage can be kept constant.</p> |
