Abstract

본 발명은 디스플레이 장치에 대한 것으로서, 전자 방해(EMI)에 의한 주파수 간섭을 줄일 수 있는 디스플레이 장치의 전원 공급 장치 및 그 방법에 대하여 개시한다. 본 발명의 실시예에 따른 디스플레이 장치의 전원 공급 장치는 디스플레이 장치의 신호처리부와 램프로 전원을 공급하기 위한 장치로서, AC 전원을 전달받는 AC 입력부; 상기 AC 전원을 DC 전원으로 변환하는 기능을 수행하고, 상기 신호처리부로 전원을 공급하는 컨버터부; 상기 DC 전원을 AC 전원으로 변환하는 기능을 수행하고, 상기 램프로 전원을 공급하는 인버터부; 및 상기 컨버터부, 인버터부 및 신호처리부의 메인 IC와 피드백 회로를 형성하는 마이컴;이 포함되고, 상기 컨버터부와 인버터부에는 각 회로의 동작으로 발생하는 노이즈 주파수를 펄스 형태의 신호로 변환하기 위한 DC 필터부가 구비되고, 상기 마이컴은 상기 DC 필터부로부터 출력되는 펄스 신호들의 분석결과를 이용하여, 상기 컨버터부 및 인버터부로 출력하는 제어신호를 달리 설정하는 것을 특징으로 한다.
