Claims (1)

LCD구동부를 내장하는 마이컴을 이용하여 LCD의 밝기를 조정하는 방법에 있어서, 프로그램 키 및 LCD밝기조정 모드키가 순차적으로 입력될시 LCD밝기 조정모드로 동작하는 과정과, 상기LCD밝기 조정모드에서 밝기 등급을 나타내는 숫자키 입력시 숫자키에 해당하는 LCD밝기 조정대이타를 출력포트로 인가하는 과정과, 상기LCD밝기 조정데이타 출력후 프로그램키 입력시 상기LCD밝기 조정모드를 해제하는 과정으로 이루어져 상기 LCD밝기 조정데이타에 따른 전압을 생성하여 상기 LCD구동부로 인가함으로서 LCD의 밝기를 자동적으로 수행할 수 있도록 동작함을 특징으로 하는 방법.In the method of adjusting the brightness of the LCD by using a microcomputer with a built-in LCD driver, the process of operating in the LCD brightness adjustment mode when the program key and the LCD brightness adjustment mode key is sequentially input, and the brightness in the LCD brightness adjustment mode The LCD brightness adjustment process includes applying an LCD brightness adjustment table corresponding to the numeric keys to an output port when a numeric key indicating a grade is input, and releasing the LCD brightness adjustment mode when a program key is input after outputting the LCD brightness adjustment data. And generating a voltage according to the adjustment data and applying the voltage to the LCD driver to automatically perform brightness of the LCD. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
