Abstract
본 발명은 투사형 화상 표시 장치에 사용되는 픽셀 보정 데이타 로딩장치에 관한 것으로, A/D 변환부(100), 픽셀 보정부(200), PROM(300), 데이타 로딩 신호 발생부(300), 프레임 메모리(400)를 포함하고 구성되어, 초기구동시 3,58MHz 신호를 사용하여 어드레스 버스를 제공하므로 PROM 의 데이타를 프레임 메모리에 원활하게 제공할 수 있고, 픽셀 보정 데이타를 프레임 메모리에 저장하여 로딩시키므로 제어라인수가 줄어들어 신호 제어가 간단해지며, SRAM 대신 프레임 메모리를 사용하므로 제작 단가를 절감시킬 수 있는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pixel correction data loading device used in a projection image display device, and includes an A / D converter 100, a pixel correction unit 200, a PROM 300, a data loading signal generator 300, a frame Since the memory 400 includes and is configured to provide an address bus using a 3,58 MHz signal during initial operation, the data of the PROM can be smoothly provided to the frame memory, and the pixel correction data is stored and loaded into the frame memory. Signal control is simplified by reducing the number of control lines, and the use of frame memory instead of SRAM can reduce manufacturing costs.
