<p>A plasma display device is provided, which includes first, second, third and fourth sustaining electrodes, and a drive circuit which provides a sustain signal consisting of multiple pulses to each electrode. In one embodiment, 3 of the 4 sustain signals are in phase, with the fourth signal out of phase. In a second embodiment, the duty cycle of all signals is varied cyclically such that, for part of the cycle, the signals supplied to adjacent electrodes are in phase, but are out of phase for the remainder of the cycle.</p> |
