Abstract
40インチを超かる高精細AC-PDPの開発を行っている。一般にPDPの解像度を上げると維持電極幅が狭くなるため、輝度が減少する。輝度が減少しないように維持電極幅を広くすると隣接ラインのとの距離が狭まり、隣接ラインとの間で放電が生じ、維持電圧マージンが急激に減少する。我々は、この現象が維持電圧バルスの波形条件に強く依存していることを見出し、維持電圧パルスを制御することによって、隣接ラインとの誤放電を防いだ。
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.
