DIGITAL DISPLAY SYSTEM

摘要

A digital display system is provided to control a display device and a lighting device at the same time in online, thereby maximizing the effect of the lighting device when it is shiny afternoon or when an image is not outputted. A digital display system comprises a main server(100), a relay computer(200), a display device(400), and a lighting device(600). The main server includes an input unit(110) and a transmitting unit(120). The input unit is connected to the relay computer by the wire/wireless Internet to input a command signal necessary for the control of the display device and the lighting device. The transmitting unit transmits the input command signal to the relay computer. The relay computer includes a data storage unit(210) and a control unit(220). The data storage unit stores digital multimedia data. The control unit controls the display device and the lighting device according to the command signal of the main server. An LVDS(Low Voltage Differential Signaling) converter converts a DVI(Digital Visual Interface) signal outputted from the relay computer into an LVDS signal. A light control adaptor(500) receives a light control signal outputted from the relay computer to control the lighting device. The lighting device is connected to the light control adaptor in parallel.
