Abstract

표시창을 갖는 장치에 관한 것으로, 특히 주변의 밝기에 따라 표시창의 밝기를 자동으로 조절하는 표시창 밝기 자동조절회로에 관한 것이다.The present invention relates to a device having a display window, and more particularly, to an automatic display window brightness adjusting circuit for automatically adjusting the brightness of the display window according to the surrounding brightness.

주변의 밝기가 수시로 변화되는 장소에서 주변의 밝기에 따라 사용자가 상기 표시창의 밝기를 수동으로 조절하여야 하는 문제를 해결하기 위해 주변의 밝기를 감지하여 그 빛의 세기에 비례하는 전압으로 변환출력하는 광전변환과정과, 상기 광전변환과정에서 변환 출력된 전압을 디지탈신호로 변환출력하는 신호변환과정과, 상기 신호변환과정에서 디지탈변환된 신호를 분석하여 주변의 밝기 상태를 판별한후 표시제어전압을 조절하는 전압 조절과정과, 상기 전압 조절과정에서 조절된 표시제어전압으로 데이타의 상태를 표시하는 표시과정으로 이루어져 주변의 밝기 변화에 따라 자동으로 표시창의 밝기를 조절한다.In order to solve the problem of the user having to manually adjust the brightness of the display window according to the surrounding brightness in a place where the brightness of the surroundings changes frequently, the photoelectric sensor detects the surrounding brightness and converts it into a voltage proportional to the intensity of the light. A signal conversion process of converting and outputting the voltage converted and output in the photoelectric conversion process into a digital signal, and analyzing the signal digitally converted in the signal conversion process to determine the brightness condition of the surroundings and then adjusting the display control voltage. And a display process of displaying the state of the data by the display control voltage adjusted in the voltage adjustment process, and automatically adjusts the brightness of the display window according to the change in the brightness of the surroundings.
