Abstract
Description
Claims (4)
- 잔류자속제거용 버튼의 동작에 따라, 제어수단이 수동적 잔류자속제거의 실시를 인지하는 단계와; 수동적 잔류자속제거가 실시될 경우, 상기 제어수단의 제어에 따라 콘트라스트제어부 및 브라이트 제어부가 씨알티의 화면의 콘트라스트 및 브라이트를 조정하여, 상기 화면을 블랙의 상태로 만들어 주는 단계와; 상기 화면이 블랙상태로 만들어진 상태에서, 상기 씨알티의 잔류자속제거가 실시되는 단계와; 상기 잔류자속제거가 완료된 후, 상기 제어수단의 제어에 따라 콘트라스트 제어부 및 브라이트 제어부가 씨알티의 화면을 원래의 상태로 회복시키는 단계; 로 이루어진 것을 특징으로 하는 씨알티의 잔류자속 제거방법.
- 제1항에 있어서, 상기 제어수단은 상기 잔류자속제거용 버튼의 동작에 따라 충전 또는 방전되는 캐패시터의 전압레벨을 감지함으로써, 상기 수동적 잔류자속 제거가 실시됨을 인지하는 것을 특징으로 하는 씨알티의 잔류자속 제거방법.
- 제1항에 있어서, 상기 제어수단은 상기 잔류자속제거용 버튼의 동작에 따라 충전 또는 방전되는 캐패시터의 전압레벨을 감지함으로써, 상기 수동적 잔류자속제거가 완료되었음을 인지하는 것을 특징으로 하는 씨알티의 잔류자속 제거방법.
- 제1항에 있어서, 상기 수동적 잔류자속제거는 상기 씨알티가 켜진 상태에서 사용자가 잔류자속제거용 버튼을 누름으로써 실시되는 것을 특징으로 하는 씨알티의 잔류자속 제거방법.
