Abstract
We have been developing the technology for high definition AC plasma display panels over 40-inch diagonals. In general, when the resolution of the PDPs increases, the brightness decreases because the sustain electrodes breadth becomes narrow. When Using wide sustain electrodes in order to increase the brightness, a discharge toward the adjacent line's sustain electrodes occurs and the sustain voltage margin abruptly decreases. We have found that this phenomenon strongly depends on the waveform conditions of the sustain voltage pulses. We have restrained the discharge toward the adjacent line's sustain electrodes by controlling the waveform conditions of the sustain voltage pulses.
