* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 디스플레이구동부 2 : 디스플레이부1: display driving unit 2: display unit

3 : 전원부 4 : 디스플레이전압감압부3: power supply unit 4: display voltage reducing unit

5 : 키입력부 6 : 키스캔부5: key input unit 6: kiss can unit

Claims (1)

키입력부(5)로 디스플레이 휘도조절 키신호가 입력될때 디스플레이구동부(1)에서 휘도조절 플래그를 세트시킴과 아울러 그리드신호의 출력시간을 최소 발광시간으로부터 최대 발광시간까지 소정시간간격으로 순차 증가시키면서 출력하고, 상기 키입력부(5)로 디스플레이 휘도조절 키신호가 다시 입력되면, 그때 그리드신호의 출력시간을 고정함과 아울러 상기 휘도조절 플래그를 리세트시킴을 특징으로 하는 디스플레이의 휘도제어방식.When the display luminance control key signal is input to the key input unit 5, the display driver 1 sets the luminance control flag and outputs the grid signal output time while sequentially increasing the output time of the grid signal from the minimum emission time to the maximum emission time. And when the display brightness control key signal is input again to the key input unit (5), the output time of the grid signal is fixed and the brightness control flag is reset. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
