If a wireless signal transmitting base station exists, the wireless signal transmitting base station is hidden behind a display screen system screen body formed by a plurality of spliced display screen units, and a video signal is transmitted to the display screen system screen body. The wireless signal transmitting base station transmits complete video information to each display screen unit, and the display screen units intercept the specific range of the video information, namely the video information of the display range corresponding to the display screen units according to the positions of the display screen units and play the video information. In this way, each display screen unit has a complete video information copy, but each display screen unit only plays the video information of the associated location. At the moment, the display screen unit needs to know the coordinates of the display screen unit relative to the screen body and know the position information of the display screen unit, and the playing range can be accurately divided.
Based on including the utility model provides a signal transmission between the display screen unit can be realized to the display screen unit of transducer device to can know the positional information between the display screen unit screen. The display screen unit can know the position information of the display screen unit and can also know the conditions of the display screen units around the display screen unit (including the position information and the played video information content) so as to accurately play the video information content.
