Abstract
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.
