Abstract
본 발명은 셀룰라 폰에 관한 것으로 셀룰라 폰이 사용되는 장소의 밝기 조건에 따라 키패드부 및 LCD의 백라이팅 밝기를 자동조절하여 배터리의 사용시간을 연장하여 양질의 통화감도를 제공하며 주변환경의 밝기에 따라 사용자의 요구에 적합하게 백 라이팅의 밝기를 설정하여 사용에 편리성을 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cellular phone, which automatically adjusts backlighting brightness of a keypad unit and an LCD according to brightness conditions of a place where a cellular phone is used, It provides convenient use by setting the brightness of the backlight to suit the needs of the user.
본 발명은 키입력수단으로 부터 인가되는 키 신호가 백라팅 기준을 설정하는 신호이면 그 값을 저장하는 제1단계와, 셀룰라 폰 사용은 위해 인가되는 키 신호를 감지하면 주변환경을 밝기를 검출 한 후 설정된 기준값과 비교판단하는 2단계와 측정된 밝기가 기준값 이상이면 백 라이팅 오프 또는설정된 광도로 백 라이팅 한후 소정시간의 경과에 따라 백 라이팅을 오프하는 3단계 및 측정된 밝기가 기준값이하이면 설정된 광도로 백라이팅하는 제4단계를 포함한다.The method comprising the steps of: storing a value of a key signal applied from a key input unit if the key signal is a signal for setting a backlit reference; detecting a brightness of a surrounding environment when detecting a key signal applied to use the cellular phone; And if the measured brightness is equal to or greater than the reference value, the backlighting is turned off or the backlighting is turned off according to the lapse of the predetermined time after the set brightness, and if the measured brightness is less than the reference value, And a fourth step of backlighting.
것을 특징으로 한다..
