Abstract

An automatic dimming liquid crystal display for protection of eyesight is provided to protect the eyesight of a user by automatically controlling the illuminance of the backlight unit of the LCD panel. A sensor for detecting light level determines the quantity of light. A sensor for detecting light level is installed at the outside upper end of a monitor. According to the sensor value which an amplifier is outputted in the sensor for detecting light level, the extent of output is determined and the brightness of the backlight unit is controlled. An MCU circuit controls the received quantity of light. The ON/OFF function is added in the monitor operation UI so that the user use in case the automatic control apparatus of the user is unnecessary.

자동 밝기 조절 액정 모니터 {Automatic Brightness Control Circuit of LCD Monitor}Automatic Brightness Control Circuit of LCD Monitor

이하에서는 본 발명에 따른 자동 밝기 조절 LCD 모니터의 구성 및 상기 시스템에 사용되는 모니터 및 장치 구조에 대해서 첨부된 도면을 참조하여 설명한다.Hereinafter, a configuration of an automatic brightness control LCD monitor according to the present invention and a structure of a monitor and an apparatus used in the system will be described with reference to the accompanying drawings.

도 1은 본 고안의 실시예에 따른 LCD 모니터 자동밝기조절장치의 블록도이다. 1 is a block diagram of an LCD monitor automatic brightness control device according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 모니터의 외부 상단에 광량을 판단 할 수 있는 광량 센서를 장착하고, 상기 광량센서에서 출력된 센서값에 따라 출력의 값을 제어하는 MCU회로와 연결된다. As shown in FIG. 1, a light amount sensor capable of determining a light amount is mounted on an external upper end of the monitor, and connected to an MCU circuit for controlling an output value according to a sensor value output from the light amount sensor.

도 2는 본 발명의 실시예에 따른 LCD 모니터 자동밝기조절장치에 있어서, 사용자가 요구하는 서비스 제공 과정을 도시한 블록도이다. 2 is a block diagram showing a service providing process required by a user in the LCD monitor automatic brightness control device according to an embodiment of the present invention.

사용자가 자동조절장치가 불필요할 경우 선택적으로 사용할 수 있도록 모니터 작동 유저인터페이스에 온/오프 기능을 추가한다.Add an on / off function to the monitor-operated user interface for optional use by users if they do not require automatic controls.

본 발명은 광량 센서를 이용하여 수광부에서 수신되는 광량을 판단하여 소비자에게 주위환경에 알맞은 조도를 출력하여 시력보호를 가능하게 한 자동밝기조절 시스템이다. The present invention is an automatic brightness control system that enables the protection of eyesight by determining the amount of light received from the light receiving unit using the light amount sensor to output the illumination suitable to the surrounding environment.

종래의 모니터는 사용자가 직접 모니터에 장착된 각종 스위치를 통하여 밝기를 조절하였고 주위 환경변화에 따른 잦은 변경이 불편함을 초래하였다. In the conventional monitor, the user directly adjusts the brightness through various switches mounted on the monitor and causes frequent inconveniences due to changes in the surrounding environment.

그러나 상기 발명에는 사용자의 불편함없이 자동으로 밝기 조절이 가능하다. 예를 들어, 주위의 조도가 낮을 경우 모니터의 조도가 상대적으로 높을 경우 눈의 피로함이나 눈물이 나는 등의 안질환을 유발 할 수 있으나 이 발명은 주위 조도와 사용자간의 최적 밝기를 출력하기 때문에 눈의 피로감을 덜어주어 시력보호를 가능하게 한다. However, the present invention can automatically adjust the brightness without inconvenience. For example, when the ambient light is low, if the monitor light is relatively high, it may cause eye diseases such as eye fatigue or tearing, but the present invention outputs the optimal brightness between the ambient light and the user. Relieves fatigue and protects eyesight.

본 발명은 종래 기술의 문제점을 극복하기 위한 것으로서, 주된 목적은 주위 환경의 밝기조건에 따라 LCD패널의 백라이트 유닛의 조도를 자동으로 조절해주어 고객으로 하여금 시력을 보호할 수 있는 LCD 모니터의 밝기자동The present invention is to overcome the problems of the prior art, the main object is to automatically adjust the brightness of the backlight unit of the LCD panel according to the brightness conditions of the surrounding environment to automatically protect the user's eyesight brightness of the LCD monitor

조절장치를 제공하는 데 있다.To provide an adjusting device.

본 발명은 광량센서를 이용하여 광량을 계산하여 MCU에서 화면 밝기를 자동을 조절한다.The present invention calculates the amount of light using the light amount sensor to automatically adjust the screen brightness in the MCU.

주위의 조도가 낮을 경우 모니터의 조도가 상대적으로 높을 경우 눈의 피로함이나 눈물이 나는 등의 안질환을 유발 할 수 있으나 이 발명은 주위 조도와 사용자간의 최적 밝기를 출력하기 때문에 눈의 피로감을 덜어주어 시력보호를 가능하게 한다.Low ambient light may cause eye diseases such as eye fatigue or tears when the monitor's light intensity is relatively high, but this invention reduces eye strain because it outputs the optimal brightness between ambient light and the user. Enable vision protection.
