Constantly innovation and development, not only the display of the display or shape, the corresponding control system, mode of operation, etc. are also increasingly intelligent development. Control system, from the earlier synchronization control system, to the asynchronous control system in recent years, and then to the current remote control, mobile wireless control, etc., LED display control method changes more easily; maintenance mode from the maintenance, to Before the maintenance, and now some companies are launched before the intelligent maintenance - can be controlled with the software, no longer artificially violent demolition, convenient maintenance, but also to protect the screen body. In addition, the past, LED display screen for outdoor large-screen display, away from the viewing crowd, and thus its functional requirements are only show the main. But with the use of LED display more and more widely, and the rapid development of intelligent technology around the world, LED display interactive performance needs have become a matter of course. As the LED tiles screen, in order to achieve better choreography effect, people, screen interactive performance is also necessary, LED sensor tiles screen also came into being.
