It’ s the article of exploring the handheld device controlling the variable LED information board remotely with wireless signal. This technology display the information on the upper control truck high-end LED screen change through the use of mobile phones with Bluetooth module,. The controlling application is written by Java which runs on Android system to provide the feasibility of the scheme. This technology can also solve the problem for urban highway guidance screen when its cable is damaged The signal need no flow cost with less mistakes and it’s low power consumption. As well, it needs to be authenticated for pro-tecting used by others. This method is easy to control. The design is novel, reliable, accurate, green, energy saving and security.
