배경
• 유일했던 CRT를 재치고 LCD를 비롯하여 LED, OELD등 여러 Display 장비들이 시장을 키워가 고 있다. • FPD의 과도기적 성향으로 인하여, 시장은 높은 화소, 큰 면적 등에 많은 관심을 가져왔으나, 현 재는 Displayer로써의 충분한 화소와 큰 면적까 지 발전되어, 앞으로 올바른 색감 및 화질이 대 두되어 그 성능을 평가할 것이다. • 따라서, 올바른 색감을 어떻게 찾을 것인지에 대 한 연구가 필요하며, 그에 따라 다음과 같은 방 법을 제시한다.

– Color in Monitor
• We can count 3 primary colors (RGB)
COLOR MATCHING SYSTEM
• Because we need a color matching System • CIE 1931 is Well-Known
