We studied the effect of self-erase discharge on the luminous efficacy of ac PDPs. We observed through discharge current analysis to confirm that the selferase discharge occurred mainly between sustain cathode and address electrode, which have an influence on the luminous efficacy. The amount and timing of the self-erase discharge was varied to observe its effect on the luminous efficacy. It has been found that the luminous efficacy could be improved by the self-erase discharge when it is adjusted to occur right before the main discharge in the small gap structure. In the long gap structure, on the contrary, the luminous efficacy could be increased when the self-erase discharge is suppressed. Also, various waveforms to control self-erase discharge are suggested and tested in the panel experiments.

Period which does an electric condition of panel in reset in the driving method of PDP is reset period. This research experimentally analyzed the priming discharge characteristic of reset period. The amount of wall charge and the accumulation time accumulated by priming discharge are unrelated to width of priming pulse. And, self-erase discharge has the relation in the amount of wall charge by priming discharge. Then, it relates also to space charge generated by priming discharge. Moreover, space charge which helps self-erase discharge exists to about 22$mutextrm{s}$ after generating priming discharge. And, it is suitable within 12$mutextrm{s}$ of priming pulse width for efficient reset.

본 연구에서는 mP의 ADS 구동방식에서 초기화기간의 프라이밍 방전 특성에 대하여 실험적인 해석을 하였다. 방전에 의해 축적되는 벽전하의 총량과 벽전하가 축적되는 시간은 프라이밍 펄스의 폭과 무관하다. 또한 과잉 벽전하에 의한 자기소거 방전은 프라이밍 방전에 의한 벽전하량과 관계가 있으며 또한 프라이밍 방전에 의해 생성되는 공간전하와도 관계가 있다. 실험결과 프라이밍 펄스 폭은 8[$\mu\textrm{s}$], 전압은 163[V] 정도가 최적이다. 그리고 자기소거방전을 돕는 공간전하는 파라이밍 방전이 발생한 직후로부터 약 16[$\mu\textrm{s}$] 동안 존재한다. 그러므로 효과적인 초기화 과정을 위한 프라이밍 펄스의 폭은 16[$\mu\textrm{s}$] 이내가 적당하다.
