Recently as new digital media like High Definition Television (HDTV) have been made popularization. However In case of image quality characteristics of AC PDP, the problem especially raised is 'image sticking' phenomenon, the phenomenon that the previously displayed pattern still remains after the image in realizing high picture quality. In this paper, Image sticking Phenomena observed in AC PDP are defined and classified, these effects are analyzed as luminance, color purity through chromaticity diagram and firing voltage state using light waveform.

본 논문에서는 저가형 PDP 구동 회로를 위한 새로운 단일 스위치 에너지 회수 회로를 제안한다. 제안한 회로는 기존의 에너지 회수 회로가 주스위치 외에 별도로 4개의 스위치가 더 필요한 데 비해 하나의 스위치만을 사용함으로써, 그 구조가 간단하여 작고 가벼우며 저가로 구현 가능하다. 또한 이 회로는 우수한 에너지 회수 성능을 보이며 패널전압을 충분히 충, 방전시킴으로써 모든 주스위치들이 영전압 스위칭하도록 하고 낮은 EMI 특성을 갖는다. 본 논문에서는 제안한 회로의 동작 원리, 설계 방법 그리고 실험 결과를 제시한다. 제안한회로는 PDP TV의 저가격화에 도움이 되리라 기대된다.

Television News has significant impact on the information analysis of viewers by delivering world news to anonymous individuals everyday. We need to pay more attention to resolution considering the fact that even slight facial expression and the dress of TV anchor can be noticed by viewers in the high definition age, called HD TV, by radical changes in broadcasting situation. As a result, the beauty of expression that lighting technology has is extremely important in the high definition age. In news broadcast, as a phenomenon according to this change in trend, people have been looking for change in order to break with traditional TV news production by adopting DLP(Digital Lighting Processing) or LED(Light Emitting Diode). This effort has contributed to creating proper picture quality appropriate for HD TV. Nowadays Digital imaging is creating new trend in TV news production method from traditional analog-based lighting environment thanks to the development of IT(Information Technology) and digitalized lighting equipment. This change has led to building of HD studio and appropriate sets and lighting system. There are film set and projector which projects image on the screen and PDP, LCD, and DLP which has been used widely in recent years and LED which is often used as background in news program as examples, which has appeared since 1990s with HD TV. In this article, I analyzed the KBS News 9 lnce 1990s with in order to research the influence of television image component on the alyzed the KBS of TV article, I. I wille uggest the category of TV anchor image formulation in delivering information by means of lnce 1990s with based on the analysis result.
