Abstract
본 발명은 휴대폰의 백라이트 전원을 제어하는 기술에 관한 것으로, 종래의 백라이트 제어에 있어서는 파워가 온된 후 계속적으로 백라이트용 발광소자를 정상적으로 구동시켜 불필요하게 전력을 낭비하게 되는 문제점이 있었는 바, 본 발명은 이를 해결하기 위하여 사용자가 휴대폰의 파워를 온시킨 상태에서 아무런 키이신호도 입력하지 않을 경우 단계적으로 백라이트용 전류를 감소시키거나, 주위의 밝기를 감지하여 백라이트를 온, 오프시킴으로써 1회의 충전으로 보다 오랫동안 휴대폰을 사용할 수 있게 되는 것이다.The present invention relates to a technology for controlling a backlight power supply of a mobile phone. In the conventional backlight control, there is a problem in that unnecessary power is wasted by continuously driving a backlight light emitting device after power is turned on. To solve this problem, if the user does not input any key signal while the mobile phone is turned on, the current for the backlight is gradually reduced or the backlight is turned on and off by sensing the surrounding brightness for a long time with one charge. You will be able to use your mobile phone.
