Abstract

본 발명은 텔레비젼이나 비디오 카세트 레코더와 같은 일반적인 가정용 전기 기기의 조명상태를 표시해주는 형광 표시판의 밝기를 사용자의 기호에 맞게 개별적으로 조절할 수 있는 형광표시판의 밝기 조절회로 및 그 방법에 관한 것인 바, 그특징적인 구성으로는 형광표시판의 밝기 조절모드를 설정하거나 해제하기 위한 밝기 조정키와 밝고 어두움의 증/감을 선택하기 위한 증가키 및 감소키를 구비한 키입력수단과, 화면 표시장치에 광량을 공급하기 위한 형광표시판과, 형광표시판의 현재 밝고 어두움 정도를 온 스크린 디스플레이(이하는 OSD라 칭함)로 표시할 수 있도록 처리하는 OSD처리수단과, 상기 OSD처리수단의 출력신호를 화면상으로 나타내기 위한 화면 표시수단과, 상기 키입력수단을 스캔하여 형광표시판의 밝기 조절모드를 설정하거나 해제하고 형광표시판의 밝고 어두움 정도를 조절하면서 그 조절상태를 OSD로 화면상에 표시하도록 제어하는 주제어수단으로 구성함에 있으며, 또한 밝기 조정키가 설정되는가를 체크하여 밝기 조정모드를 설정하는제 1단계와, 상기 제 1단계에서 설정된 밝기 조정모드에서 밝기 증가키가 입력되면 형광표시판을 밝게 조정하면서 그 조정상태를 OSD로 화면에 표시하는 제 2단계와, 상기 제 1단계에서 설정된 밝기 조정모드에서 밝기 감소키가 입력되면 형광표시판을 어둡게 조정하면서 그 조정상태를 OSD로 화면에 표시하는 제 3단계와, 상기 제 1단계에서 설정된 밝기 조정모드에서 밝기 조정키가 다시 입력되거나 일정한 시간이 지나도록 아무런 키입력이 없으면 밝기 조정모드를 해제한 후 정상모드로 복귀하는 제 4단계로 이루어짐에 있다.The present invention relates to a brightness control circuit and a method of adjusting the brightness of the fluorescent display panel to display the lighting state of a general household electrical equipment such as a television or video cassette recorder individually according to the user's taste, Its characteristic configuration includes key input means including a brightness adjusting key for setting or releasing a brightness adjusting mode of the fluorescent display panel, and an increasing key and decreasing key for selecting increase / decrease of bright and dark, and the amount of light in the screen display device. An on-screen display (OSD) processing means for displaying a fluorescent display panel for supplying, an on-screen display (hereinafter referred to as OSD), and an output signal of the OSD processing means on a screen; Screen display means, and the key input means to scan or set the brightness control mode of the fluorescent display panel. And the main control means for controlling the brightness and darkness of the fluorescent display panel to display the adjustment state on the screen using the OSD. Also, the first step of setting the brightness adjustment mode by checking whether the brightness adjustment key is set and When the brightness increase key is input in the brightness adjustment mode set in the first step, the second step of displaying the adjustment state on the screen by OSD while brightly adjusting the fluorescent display panel and decreasing the brightness in the brightness adjustment mode set in the first step When the key is pressed, the fluorescent display panel is darkly adjusted and the adjustment state is displayed on the screen by the OSD. In the brightness adjustment mode set in the first step, the brightness adjustment key is input again or any key input is made to pass. If not, the fourth step is to return to the normal mode after canceling the brightness adjustment mode.
