Abstract
본 발명은 액정 표시 장치의 텔레비젼 수상기에 백 라이트의 전력소모가 큰 비중을 차지하므로 시청자 부재 시에는 백 라이트를 오프시킴으로써 액정 표시장치(Liquid Crystal Display)텔레비젼 수상기의 절전장치 및 방법에 관한 것으로서, 시청자의 존재 유무를 판별하는 위치 감지 센서; 상기 위치 감지 센서로부터 출력된 신호를 증폭하는 증폭기; 상기 증폭기로부터 출력된 아날로그 신호를 디지탈 신호로 변환시키는 아날로그 디지탈 변환기; 및 상기 아날로그 디지탈 변화기로 부터 출력된 신호를 입력받아, 백라이트 온/오프 신호를 출력시키는 마이크로 프로세서를 포함한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power-saving device and method for a liquid crystal display television receiver by turning off the backlight in the absence of the viewer because the power consumption of the backlight occupies a large portion in the television receiver of the liquid crystal display device. Position detection sensor for determining the presence or absence of a; An amplifier for amplifying the signal output from the position sensor; An analog digital converter for converting an analog signal output from the amplifier into a digital signal; And a microprocessor which receives a signal output from the analog digital transducer and outputs a backlight on / off signal.
따라서 상술한 바와 같이 본 발명에 따른 액정 표시장치 텔레비전 수상기의 백라이트 절전장치 및 방법은 시청자의 유무를 판별하여 시청자가 없으면 백라이트를 오프시킴으로써 전력소모가 큰 백라이트를 오프시켜 소비전력을 절약하는 효과를 갖는다.Therefore, as described above, the backlight power saving device and method of the liquid crystal display television receiver according to the present invention can determine whether the viewer is present and turn off the backlight when there is no viewer, thereby saving power consumption by turning off the backlight having a large power consumption. .
