A new high-speed drive method for the plasma display panel is proposed. In this method, the address period is inserted for the rest period of the sustain pulses and the printing pulse is applied on the entire panel at the same time overlapping with the sustain period. The ramp shaped printing pulse can be made with a simple drive circuit in this technology and the stable sustain discharge can be induced even by a narrow scan pulse in help of the space charge generated from the address discharge. From the experiments, it is ascertained that the priming pulse hardly influences the sustain discharge. Moreover, the voltage margin of the sustain discharge is almost constant though that of the address discharge broadens with narrowing the scan pulse width. And, if the time interval between the scan pulse and the sustain pulse is within 6㎲, the voltage margin of the address and the sustain discharges are unaffected though the applied position of the scan pulse is changed. High-speed driving with the address pulse of 0.7㎲ width was achieved and the address voltage margin of 20V and the sustain voltage margin of 10V were obtained.

본 연구에서는 새로 고안된 AND gate PDP의 AND gate를 구성하는 4개의 DC 방전셀에 대한 상호간의 영향을 방전특성 측면에서 규명하였다. 이 4개의 방전셀들의 방전개시 전압은 인접한 방전셀의 방전에서 발생하는 공간전하와 깊은 관련이 있다는 것을 알았다. 실험 결과 각 방전셀의 최적화된 방전 전압을 결정할 수 있었으며 PDP의 address 방전에 이용되는 floating 방전을 도와주는 priming 방전의 동작마진을 얻기가 어렵다는 것을 정석적으로 알 수 있었다. This research investigated the influence on the 4 cell of DC discharge on the side of the discharge characteristic. This DC discharge cells are that composes AND gate of AND gate PDP newly proposed. As for the discharge starting voltage of this discharge cell of 4 pieces, it has been understood that there is deeply a relation up to the space charge generated from the discharge of adjoining discharge cell through the experiment. The discharge voltages which had become each discharge cell optimizations from the experiment result were decided. Moreover, the width of the margin of two AND input voltages is wide and the AND function occurs clearly. However, it has been qualitatively understood that it is difficult enough to obtain the operation margin of the DC priming discharge used to address discharge of PDP.

This research concerns the ADS drive method of 3 electrodes AC PDP and is determined the minimum pulse width of the address and the sustain, which the steady sustain discharge without decreasing luminance can be obtained. From the experimental result, if the address pulse width became $1.5[{\mu}s]$ or more a effective address discharge with the operating margin of 35[V] was possible. And if the sustain pulses width became $2[{\mu}s]$ or more, a steady sustain discharge with the operation margin of 25[V] was possible. When this condition is applied to Full-HDTV class PDP with the in lines of horizontal scanning lines, 8 sub-fields and total 1420 sustain pulses can be used. 본 연구는 3 전극 교류구동형 PDP의 ADS구동방식에 관한 것으로 휘도의 저감이 없는 안정적인 표시방전이 가능한 최소의 어드레스와 표시방전 유지펄스의 폭을 도출하는 것이다. 실험결과로부터 어드레스 펄스폭이 $1.5[{\mu}s]$이 상만 되면 효과적인 어드레스 방전이 가능하였고 35[V] 어드레스 동작마진을 얻을 수 있었다. 또한, 표시방전 유지펄스의 폭이 $2[{\mu}s]$이상 되면 25[V]의 동작마진을 가지고 안정적인 표시방전의 유지가 가능하였다. 이 조건들을 수평 주사선수 1080라인의 Full-HDTV급 PDP에 적용할 경우 8개의 서브필드와 총 1420개의 표시방전 유지펄스를 사용할 수 있다.
