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.

Description

휴대폰의 백라이트 제어방법How to Control Backlight of Mobile Phone

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명의 백라이트 제어방법이 적용되는 휴대폰의 제어블럭도, 제4도는 본 발명의 다른 백라이트 제어방법이 적용되는 휴대폰의 제어블럭도.2 is a control block diagram of a mobile phone to which the backlight control method of the present invention is applied, and FIG. 4 is a control block diagram of a mobile phone to which another backlight control method of the present invention is applied.

Claims (2)

파워키이신호가 입력되면 일단 백라이트 구동전류를 정상적으로 공급하고, 시간이 경과됨에 따라 그 구동전류를 단계적으로 감소시키다가 소정시점에서 백라이트 구동전류를 완전히 차단시키고, 그 도중에 키이신호가 입력되면 다시 백라이트 구동전류를 정상적으로 공급하는 것을 특징으로 하는 휴대폰의 백라이트 제어방법.Once the power key signal is input, the backlight driving current is supplied normally, and the driving current is gradually reduced as time passes, and the backlight driving current is completely cut off at a predetermined time. Backlight control method for a mobile phone, characterized in that the current is supplied normally. 파워가 온되면 휴대폰 주위의 밝기를 체크하여 밝으면 엘씨디와 키이패드의 백라이트를 오프시키고, 어두우면 백라이트를 온시키고 임의의 시간동안 소정의 키이신호가 입력되는지를 확인하는 입력되지 않으면 백라이트를 오프시키고, 입력되면 초기상태로 복귀하는 제1단계와, 외부로 전화가 걸려올 때 주위의 밝기를 체크하여 어두우면 엘씨디와 키이패드의 백라이트를 온시키고, 밝으면 백라이트를 오프시킨 상태에서 톤신호를 출력하는 제2단계와, 전화를 걸거나 받을 때 엔드키이가 입력되면 지정된 시간에 관계없이 상기 백라이트를 오프시키는 제3단계로 이루어지는 것을 특징으로 하는 휴대폰의 백라이트 제어방법.When the power is turned on, the brightness around the phone is checked and the backlight of the LCD and keypad is turned off when it is bright, the backlight is turned on when it is dark, and the backlight is turned off when it is not input. When input, the first step to return to the initial state, and when the call to the outside checks the brightness of the surroundings, if it is dark to turn on the backlight of the LCD and the keypad, if it is bright outputs the tone signal with the backlight off And a third step of turning off the backlight regardless of a specified time when an end key is input when making or receiving a call. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임※ Note: The disclosure is based on the initial application.
