Abstract
본 발명은 화면 사이즈의 변화에 따라 자동적으로 화면 밝기가 조절되게 한 모니터의 화면 밝기 자동조절 회로에 관한 것으로, 수평 사이즈 변동 출력을 내보내는 수평출력부(4), 수직사이즈 변동 출력을 내보내는 수직출력부(5), 수평, 수직 출력부(4)(5)의 출력 파형을 임피던스 분리하고 DC 전압으로 변경시켜 출력시키는 밝기 조절부(6) 밝기 조절부의 출력, 즉 수평, 수직 화면 사이즈의 변동에 따라 입력되는 영상증폭율을 변화시키는 증폭부(1), 증폭부의 주파수를 보정하는 주파수 보정부(3)를 구비하여 이루어진다.The present invention relates to an automatic screen brightness adjustment circuit of a monitor that automatically adjusts screen brightness according to a change in screen size. The present invention relates to a horizontal output unit 4 for outputting a horizontal size variation output and a vertical output unit for outputting a vertical size variation output. (5), the brightness control unit for separating the output waveform of the horizontal, vertical output unit (4) (5) by impedance separation and changing to DC voltage (6) the output of the brightness control unit, that is, in accordance with the change in the horizontal, vertical screen size And an amplifying section 1 for changing the input image amplification ratio and a frequency correcting section 3 for correcting the frequency of the amplifying section.
