Abstract

A novel priming discharge technique in which the ramp shaped priming pulse is superposed on the sustain period so that the entire plasma display panel (PDP) is discharged at the same time with a single drive circuit is proposed. From the experimental results, it is ascertained that the priming discharge is ignited only in a pixel in which sustain discharge does not occur and it has been understood that the priming pulse hardly influences the sustain discharge. Moreover, high-speed driving with address pulse widths of 0.7[${\mu}s$] was achieved and a wide address voltage margin of 40[V] was obtained by using the drive method applied the proposed priming discharge technique. In these results, full-HDTV PDP with 1080 horizontal scanning lines can be driven without decreasing the brightness and the possibility of the commercializing is also high because this technology is designed for using the commercialized driver IC.

램프(ramp) 파형의 프라이밍 펄스를 표시방전 유지기간에 중첩시켜 인가함으로써, 단일 구동회로를 사용하여 플라즈마 디스플레이 패널(PDP)의 전체를 동시에 방전시킬 수 있는 새로운 프라이밍(priming) 방전기술을 고안하였다. 실험결과로부터 표시방전이 없는 화소에만 프라이밍 방전이 일어남을 확인하였으며 표시방전은 프라이밍 펄스의 영향을 거의 받지 않는다는 것을 알았다. 또한 제안된 프라이밍 방전 기술을 적용한 구동방식을 사용하여 0.7 [${\mu}s$]의 어드레스 펄스폭을 가지는 고속 구동을 실현하였고 40[V]의 넓은 어드레스 전압 범위를 얻었다. 이 결과는 1080개의 수평주사선수를 가지는 full-HDTV PDP를 밝기의 감소 없이 구동할 수 있으며 이 기술은 상용의 구동IC를 사용할 수 있도록 설계되었으므로 상용화 가능성도 높다.
