Interactive induction of the implementation principle of LED floor tile screen

　　After the special playback video source, first control the special playback software in the computer through the LED display screen, DVI/HDMI and other signal outputs, connect to the main controller of the video signal processing through the signal line; Signal distributor, allocate the LED display display to play the full screen.

　　When the full -color LED display interacts with the audience, the sensor sensor on the LED display detects the interactive point of the interactive audience. After controlling the computer, after the computer receives the position coordinate information, the control software can be transmitted to the LED display to control the computer according to the coordinate information they received, and call different program files and video files for playback. The picture has corresponding real -time changes to achieve the effect of real -time interaction.

　　It can be known from the necessary conditions and principles of interactive induction LED floor tile screens. Compared with the traditional LED display, it is mainly different:

　　The first is the difference in control software: the traditional LED display is on the playback end, only ordinary playback software is required, and the video source will be played without receiving other signals. The interactive LED display is different. He not only can play, but also can receive the interactive point position coordinate information transmitted by the display screen. After receiving the location coordinate information, the control software can call according to the receiving coordinate information. Different program files and video files are played. This is the same as that when we play games on the computer, the LED display is like a computer display. Interactive audiences are like mouses. Interactive points are like the position of the mouse. Click the mouse in different locations to call different programs.

　　The second is that the direction of the data transmission is different. The data of the traditional LED display is mainly transmitted from the control end to the display end. Basically, the interactive LED display increases the data return, which is a two -way transmission.

　　The third is the different display of the LED screen body. The traditional LED display only plays a display role. Interactive induction LED floor tile screen also needs to be sensing, collecting, and transmitting the interactive point coordinate information of the interactive point of interactive audiences to locate the interactive point. This is the most important part of the interactive LED display.
