The LED floor tile screen is a novel digital display device customized for the use environment of indoor exhibition hall, stage party and so on. Flexible modular design can realize various applications such as floor, ceiling, T stage and so on. Although the current LED floor tile screen can achieve similar effects by pre-designing the video, the scene of the performance is often full of uncertainty. It requires a dedicated staff to be responsible for the video playback and adjustment. To be timely and accurate, the interactive LED floor tile screen can solve this problem in a targeted manner.
The specially processed playback video source is first played by the special playback software in the computer controlled by the LED display, and DVI/HDMI signal output. It is connected to the main controller of the video signal processing through the signal line, and then connected to the signal distributor through the optical fiber or network cable, so as to distribute and display the complete picture. When the LED floor tile screen interacts with the audience, the position sensor on the display screen detects the interactive point of the interactive audience, and the positioning controller of the floor tile screen transmits the position coordinate information of this interactive point back to the LED display control computer. After the control computer receives the position coordinate information, the control software can send it back to the LED display control computer according to the received coordinate information. After the control computer receives the position coordinate information, the control software can call different program files and video files to play according to the received coordinate information, and the screen displayed on the LED floor tile screen will have corresponding real-time changes to achieve real-time interaction effect.
The first is the difference in control software. The traditional LED display screen is on the playback side, and only ordinary playback software is needed to play the video source without receiving other signals. The interactive LED floor tile screen is different. It not only needs to be able to play, but also to be able to receive the coordinate information of the interactive point's position returned from the display screen. After receiving the position coordinate information, the control software can call different program files and video files to play according to the received coordinate information. This is the same as when we play games on the computer. The LED display is like a computer monitor, the interactive audience is like a mouse, and the interactive point is like the position of the mouse. Clicking the mouse at a different location will call different programs.
The second is that the direction of data transmission is different. The data of the traditional LED display is mainly transmitted from the control end to the display end, which is basically one-way. The LED interactive induction floor tile screen increases the data return, which is a two-way transmission.
The third is the difference between the display end of the LED screen. The traditional LED display only plays a display role, while the interactive LED floor tile screen also needs to sense, collect and transmit the coordinate information of the interactive point of the interactive audience to locate the interactive point. It is the most important and critical part of the interactive LED display.
