Realize the interactive LED floor tile principle block diagram: After special processing of the playback video source, firstly through the LED display to control the special playback software in the computer to play, DVI / HDMI and other signal output, through the signal line to the main controller of the video signal processing Then connect to the signal distributor through fiber or network cable, and the distribution shows the full screen. When the LED floor screen interacts with the audience, the position sensor on the display sensor detects the interaction point of the interactive viewer, and the position controller of the floor tile screen transmits the position coordinate information of the interaction point to the LED display control computer to control After the computer receives the position coordinate information, the control software can transmit back to the LED display control computer according to the received coordinate information, and after the control computer receives the position coordinate information, the control software can call according to the received coordinate information. Different program files and video files are played, and the screen displayed by the LED interactive floor screen has a corresponding real-time change, achieving the effect of real-time interaction.

Second, from the realization of the necessary conditions and principles of LED interactive sensing of the brick screen, it can be known that compared with the traditional LED floor tile screen, there are three main differences:

The first is the difference in control software. The traditional LED display screen only needs ordinary playing software on the playing end, and the video source can be played out without receiving other signals. The interactive LED floor tile screen is different. He not only needs to be able to play, but also can receive the coordinate information of the interactive point position returned from the display terminal. After receiving the position coordinate information, the control software can call according to the received coordinate information. Different program files and video files are played. This is the same as when we play games on a computer. The LED display is like a computer monitor. The interactive audience is like a mouse. The interaction point is like the position of the mouse. When you click the mouse in different positions, different programs are called.

The second is that the direction of data transmission is different. The data of the traditional LED display screen is mainly transmitted from the control end to the display end, which is basically one-way, and the LED interactive sensing floor tile screen increases the data return, which belongs to two-way transmission.

The third is the difference of the display end of the LED screen. The traditional LED display only plays the role of display. The interactive LED floor screen also needs to sense, collect and transmit the coordinate information of the interactive point of the interactive viewer, and locate the interactive point. This is the most important and most important part of the interactive LED display.
