The present invention relates to an outdoor display apparatus, which comprises: a display panel having division backlight modules which divide a display screen area to project light, and a liquid crystal display module which displays display information by means of the light projected by the division backlight modules; a luminous intensity sensor which detects the external luminous intensity; and a control module which controls the display panel such that display information received by means of a terminal communication unit may be displayed in the display panel, and controls such that the division backlight modules may be operated when the luminous intensity detected in the luminous intensity sensor is determined to be lower than a standard luminous intensity corresponding to the dark field condition. The outdoor display apparatus according to the present invention may adjust the driving condition of the division backlight modules during the late-night hours and according to surrounding information to extend the service life of the display panel. Furthermore, the present invention may be operated at low power to reduce electricity consumption.
본 발명은 옥외 디스플레이 장치에 관한 것으로서, 표시화면영역을 분할하여 광을 조사할 수 있도록 된 분할백라이트모듈들과, 분할 백라이트모듈들에 의해 조사된 광에 의해 표시정보를 표시하는 액정표시모듈을 구비하는 표시패널과, 외부 조도를 검출하는 조도센서와, 단말통신부를 통해 수신된 표시정보가 표시패널에 표시되게 표시패널을 제어하고, 조도센서에서 검출된 조도가 암시야 조건에 해당하는 기준조도 이하인 것으로 판단되면 분할 백라이트모듈이 가동되게 제어하는 제어모듈을 구비한다. 이러한 옥외 디스플레이 장치에 의하면, 심야시간대 및 주변 정보에 따라 분할 백라이트모듈의 구동 조건을 조정함으로써 표시패널의 사용수명을 연장할 수 있고, 저전력으로 구동할 수 있어 사용 전력을 절감할 수 있는 장점을 제공한다.
