초록

평판 디스플레이는 얇고 가벼운 영상 표시 장치로 기존의 CRT를 대체하여 거의 모든 영역의 디스플레이에 사용되고 있으며, 액정 표시 장치, 플라즈마 표시 장치, 유기 발광 표시 장치 등이 있다. 이러한 디스플레이들이 현재 또는 미래의 경쟁력을 갖추려면 표시 장치의 특성에 맞는 고화질, 저소비 전력의 구동 기술을 확보해야 한다. 본 논문에서는 소형에서부터 대형에 이르기까지 널리 사용되는 TFT-LCD, 특히 LCD TV에서의 대한 고화질, 저소비 전력의 구동 기술에 대하여 살펴 보고, 향후 기술적 과제에 대하여 분석하고자 한다. 또한, 새로 부각되고 있는 AMOLED의 구동 방식에 대하여 살펴보고 기술적 과제에 대하여 논하고자 한다.

Abstract

Flat panel displays (FPDs) such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting diode (OLED) displays alternate cathode-ray tube (CRT) displays because of the thin and light form factor. For having competitive power in nowadays, these displays should have high image quality and low power consumption. In this paper, the driving technology with high image quality and low power consumption in LCD TV for small to large size panel will be analyzed and the technology issues will be discussed. Furthermore, the driving technologies and issues of upcoming future display, AMOLED display, will be discussed.
