Abstract
이 발명은 디지찰 색상신호 조정장치에 관한 것으로서, 그래픽 카드에서 출력되는 적색을 나타내는 디지탈 색상신호를 입력받아. 적색의 그레이 레벨을 원하는 만큼 감소시켜 출력하는 제1감산기와; 그래픽 카드에서 출력되는 녹색을 나타내는 디지탈 색상신호를 입력받아, 녹색의 그레이 레벨을 원하는 만큼 감소시켜 출력하는제2감산기와; 그래픽 카드에서 출력되는 청색을 나타내는 디지탈 색상신호를 입력받아, 청색의 그레이 레벨을 원하는 만큼 감소시켜 출력하는 제3감산기와; 상기 제1감산기, 제2감산기, 제3감산기의 출력신호와 제어 신호를 입력받아, 각 색의 밝기가 조정된 디지탈 색상신호를 액정표시장치 구동회로로 출력하는 인터페이스 집적회로로 구성되어, 디지탈 데이타인 적, 녹, 청의 색상신호를 제어하여 각 색의 밝기 정도를 조정함으로써 전체화면의 색상 조합이 자연색을 표현하도록 하며, 원하는 색상 표시가 가능하게 하는 디지탈 색상신호 조정장치에 관한 것이다.The present invention relates to a digital color signal adjusting device, which receives a digital color signal representing red output from a graphics card. A first subtractor which reduces and outputs a red gray level as desired; A second subtractor for receiving a digital color signal representing green output from the graphic card, and reducing and outputting the green gray level as desired; A third subtractor for receiving a digital color signal representing blue output from the graphics card and reducing and outputting a gray level of blue as desired; And an interface integrated circuit which receives the output signals and control signals of the first subtractor, the second subtractor, and the third subtractor, and outputs a digital color signal of which brightness of each color is adjusted to a liquid crystal display driving circuit. The present invention relates to a digital color signal adjusting device that controls the color signals of human, green, and blue to adjust the brightness level of each color so that the color combination of the entire screen expresses the natural color and enables the desired color display.
