Abstract
본 논문에서는 저가형 CSTN-LCD(Color Super-Twisted Nematic Liquid Crystal Display)에 사용하는 동영상 프로세서를 제안한다. 제안된 프로세서는 SFP(SubFrame Pattern) 기법을 적용하여 계조 확장을 할 뿐 아니라 플리커(flicker)현상을 제거하였고 BFI(Black Field Insertion) 기법을 적용하여 액정의 응답시간을 보상하였다. 그리고 화질 향상을 위한 에지 강조 기법과 보간기법을 적용하였다. 하드웨어 구조는 FPGA 프로토타입 보드를 사용하여 검증하였다. 제안된 동영상 프로세서는 PDA(Personal Digital Assistants), 모바일 폰과 PMP(Portable Multimedia Player) 등에 사용되어 질 수 있다.
In this paper, we proposed a motion picture processor for using low-cost color super twisted nematic liquid crystal display(CSTN-LCD). The proposed processor apply a new driving scheme using SFP (Subgroup Frame Pattern), so we extends gray scale and eliminates flicker phenomenon. In addition, we apply the BFI (Black Field Insertion) to the design compensated for response time of a LC (Liquid Crystal). We use an edge enhancement and interpolation method to improve image quality of motion picture. The hardware architecture of proposed processor has been implemented and verified on a prototype FPGA board. The proposed method can be used in the display devices such as PDA(Personal Digital Assistants), mobile phone, and PMP(Portable Multimedia Player).
