本論文提出在電漿顯示器每一個子圖場的維持時段中，利用斜緩維持波形以及在寫入電極上加入輔助電壓方波的方法，提升電漿顯示器發光效率的新驅動波形。斜緩維持波形的特徵為其電壓上升時間較傳統波形增加了三倍左右,其有助於降低氣體放電時的空間電壓差和累積足量的壁電荷以維持腔體中氣體放電作用得以連續產生的效果。在高維持頻率的情況下，當斜緩維持波形電壓值仍低時，在寫入電極上加入輔助電壓方波產生一次“先期放電”。此“先期放電”不但清除了部份的壁電荷還增加空間中帶電荷粒子數量並使得其後產生的維持放電可於較低電壓時開始。當氣體放電於較低電壓的情況下，電子溫度較低並可以提高發光要率。在高維持頻率下，利用此新的驅動波形可以較傳統波形提升百分之二十八的發光效率。

In this thesis, an evolutional waveform in sustain period by combining the ramp-type sustain pulse with the auxiliary pulse on address electrode is proposed to improve the luminous efficiency in plasma display panel. The ramp-type sustain waveform is featured with the longer rise-time than the conventional waveform and it is a compromise to let gas discharge with lower cell voltage but still helps accumulate enough wall charges to sustain discharge sequence in cells. For high sustain frequency, adding an auxiliary pulse on address electrode in the early stage of ramp-type sustain pulse to induce a pre-discharge. The pre-discharge not only eliminates partial wall charges but also increases density of priming particles which help the coplanar-type discharge start at a lower cell voltage. The increase of luminous efficiency is a result of the decreased cell voltage and electron temperature in discharge. For high sustain frequency, a total of 28 % improvement in luminous efficiency has been achieved by the new waveform while comparing with the conventional sustain waveform.
