Abstract
본 발명은 별도의 조정노브 없이 휘도 등 화면의 표시상태를 조절할 수 있는 표시장치의 회로를 제공한다.The present invention provides a circuit of a display device that can adjust a display state of a screen such as luminance without a separate adjusting knob.
본 발명에 의하면 사용자가 키보드를 통해 화면 표시 조절 지령을 입력하면 키보드 제어부가 이에따라 제어신호를 발생시킴으로써 액정패널이나 음극선관등 표시장치의 출력 레벨 등을 조절하게 된다.According to the present invention, when a user inputs a screen display control command through a keyboard, the keyboard controller generates a control signal accordingly to adjust an output level of a display device such as a liquid crystal panel or a cathode ray tube.
이에 따라 별도의 조절노브를 구비하지 않아도 되므로 케이싱의 구조 및 설계를 단순화 할 수 있고 제작코스트도 절감시킬 수 있어서, 특히 노트북형 PC 등 소형 휴대용 컴퓨터의 발전에 크게 기열할 수 있다.Accordingly, the structure and the design of the casing can be simplified and the manufacturing cost can be reduced since there is no need to provide a separate adjusting knob. In particular, the development of a small portable computer such as a notebook PC can be greatly improved.
