Abstract
본 발명에 따른 LCD의 자동 밝기 조절장치는 사용자가 동작상태를 인지하기 위한 표시부를 LCD를 사용하는 전자 제품에 있어서, 상기 전자 제품의 각 소자에 시간 정보를 제공하는 타이머부와, 상기 타이머부로부터 제공된 현재 시간과 기준 시간을 비교하여 상기 LCD의 밝기를 조절하도록 제어하는 제어부와, 상기 기준 시간을 다단계로 저장하고 상기 제어부의 제어에 따라 상기 현재 시간이 속하는 기준 시간에 저장된 상기 LCD의 밝기에 대한 정보를 출력하는 저장부와, 상기 제어부의 제어에 따라 상기 표시부의 밝기를 조절할 수 있는 구동신호를 출력하는 표시 구동부를 구비한다. 따라서, 본 발명은 전자 제품의 표시소자 사용되는 LCD의 밝기를 현재 시간에 따라 조절하므로 사용자의 눈의 피로를 절감시킬 수 있다.According to an aspect of the present invention, there is provided an apparatus for automatically adjusting brightness of an LCD, comprising: a timer for providing time information to each element of the electronic product, wherein the display unit for the user to recognize an operation state is an LCD; A control unit for controlling the brightness of the LCD by comparing the present time with a reference time, and storing the reference time in multiple stages and controlling the brightness of the LCD stored at the reference time to which the current time belongs under the control of the controller. And a storage unit for outputting information and a display driver for outputting a driving signal for adjusting the brightness of the display unit under the control of the controller. Accordingly, the present invention can reduce the eye fatigue of the user because the brightness of the LCD used for the display device of the electronic product is adjusted according to the current time.
