Abstract

흑백 디스플레이 장치에서는 조사 레벨이 증가 할 때 조사 부위의 광학적 중심을 일정하게 유지 하는것이 중요한 것으로 알려져 있다. 따라서, 임의의 픽셀 구성은 조사 부위의 광학적 중심을 유지할 필요성과 디스플레이의 픽셀을 구동시키기 위한 실제적인 조건간의 교환조건(trade off)을 포함한다.
풀 컬러 픽셀 디스플레이에서는 풀 컬러 구성과 흑백 픽셀 구성간의 차로 인해 부분적 또는 실제적으로 광학적 중심을 유지 해야 할 필요성이 저감될 수 있다. 따라서, 조사 부위의 광학적 중심을 유지하기 위한 저감된 필요성을 갖는 풀 컬러 디스플레이의 픽셀 구성(30)과 아울러 저감된 광학적 중심 필요성에 따라 풀 컬러 픽셀을 구성하는 방법이 기술되어 있다.
