초록

현재 Fringe-field switching(FFS) 액정 모드는 고화질 및 고정세 액정 디스플레이에 주로 적용되고 있다. 본 총설에서는 FFS모드의 어떠한 동작원리가 기존에 다른 액정모드 보다 왜 우수한 전기광학 특성을 갖는지에 대한 상세 한 설명과 더불어 FFS모드의 역사적 발전 현황, 기술의 현 주 이슈 및 향후 발전방향을 기술한다.

Abstract

Recently, the fringe-field switching (FFS) mode in liquid crystal displays has been used mainly for high image quality andhigh-resolution liquid crystal displays (LCDs). In this review paper, the fundamental switching principle of the FFS mode, withits excellence over other LC modes in electro-optic performance, will be described. In addition, the development history, presenttechnical issues, and future of the FFS LCD will be discussed.
