Claims (2)
- 색좌표가 서로 다른 제1 광원, 제2 광원 및 제3 광원의 광원셀이 다수 개로 이루어진 전광판;
상기 광원셀의 각각의 광원에 전원을 공급하기 위한 전원부;
상기 하나의 광원셀에 전원을 공급하는 한 주기(T)에 대해 색좌표 시비율에 따라 전원을 제1시간(t1)에 제1 광원에 공급하고 제2시간(t2)에 제2 광원에 공급하며 제3시간(t3)에 제3 광원에 공급하도록 제어하며, 상기 한 주기(T)가 일정 시간 동안 반복되도록 제어하는 제어부;
상기 하나의 광원셀을 이루는 제1 광원과 제2 광원 및 제3 광원에 전원을 공급하는 상기 제1 시간(t1)과 상기 제2 시간(t2) 및 상기 제3 시간(t3)에 대한 색좌표 시비율에 대해, 외부로부터 입력되는 문자나 숫자, 기호, 이미지, 동영상을 포함하는 멀티미디어 데이터에 따라 자동으로 설정하는 색좌표 시비율 설정부;
를 포함하는 엘이디 광원 색좌표 조절 장치.
- 제 1 항에 있어서,
상기 멀티미디어 데이터를 통신망을 통해 수신하기 위한 통신부를 더 포함하고,
상기 색좌표 시비율 설정부는 상기 통신부를 통해 수신된 멀티미디어 데이터에 따라, 상기 다수 개의 광원셀에서 각각의 광원이 발광되므로 상기 전광판에 표출되는 내용이 상기 멀티미디어 데이터를 이루도록 색좌표 시비율을 자동으로 설정하는 것을 특징으로 하는 엘이디 광원 색좌표 조절 장치.
