Abstract
Description
US 2003/128174 A1은 상이한 원색들의 4개의 LED들을 포함하는 픽셀들을 갖는 매트릭스 디스플레이를 개시한다. 관련된 제어 알고리즘에서, LED들은 그들의 광출력이 3개의 주어진 타겟 값들을 만족시키는 한편 부가적으로 구동 명령들의 함수가 최소화되도록 구동된다. 최소화된 함수에 대한 예들로는 하나의 LED의 소모된 전력, 전류 또는 동작 시간이 있다.
WO 2006/109237 A는 적어도 4개의 주광원들에 대한 제어 명령들을 결정하기 위한 방법을 개시한다. 칼라 공간 내의 타겟 포인트에 대한 명령들은 광원들에 의해 발생될 수 있는 알려진 특성의 칼라 공간 내의 추가적인 포인트를 고려하여 획득될 수 있다.
US-A-6014457은 서로 다른 칼라 공간들간의 좌표 변환들이 실행되는 장치를 개시한다.
