Abstract
본 발명은 백라이트 밝기가 주위 환경의 밝기 정도에 따라 자동으로 조절되도록 하기에 적합한 백라이트 밝기 자동 조절 장치에 관한 것으로, 종래에는 백라이트가 일정 광도를 유지할 경우 주변 밝기에 따라 상대적으로 액정 디스플레이의 화상 선명도가 다르게 되기 때문에 결국, 주변 밝기가 다르게 될 때마다 휘도 조절부를 제어하여 백라이트의 밝기를 직접 조절해야하는 불편함이 있었으나, 본 발명에서는 광센서부(120)의 주변 밝기 센싱에 따라 백라이트(150)의 밝기가 자동으로 조절되므로서 사용자는 어떠한 환경에서도 항상 액정 디스플레이를 최적의 휘도 상태로 사용할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically adjusting backlight brightness, which is suitable for automatically adjusting backlight brightness according to the degree of brightness of the surrounding environment. In the end, the brightness of the backlight 150 is changed according to the ambient light sensing of the optical sensor unit 120. Is automatically adjusted so that the user can always use the liquid crystal display at the optimum brightness in any environment.
