Design and Implementation of Super-long LED Panel Under Complex Electromagnetic Environment

A realization scheme of the super-long LED panel under the complex electromagnetic environment is presented.The system control card with LPC2220FBD144 chip is as the core,P10 module is selected in display unit.A new power supply topology design of LED panel module is used.The dynamic characteristics of super-long LED panel is fully considered in system hardware design and installation,as well as the EMC under complex electromagnetic environment.Experiments prove that the system is stable,its indicators of dynamic characteristics,electromagnetic interference and so on meet the design requirements,and cost-effective.
