Zhang Yujie1,Ma Liyun2,Zhang Heyan3(1.College of Electrical and Information Engineering,Shaan Xi University of Science and Technology,Xi'an 710021,China;2.Sinopec Zhongyuan oil field branch Natural Gas Purification Plant,Dazhou 636156,China)  
According to the characteristics of large LED module structure,comibining with the technology of CPLD,the dynamic scanning display of the LED display screen was realized.A LED-screen Display Control System based on ARM and FPGA was designed.Under the control of the core chip S3C2440 with the help of programmable logic device EP1C6,the control system accomplished the data store and update,cartoon processing,circulation showing etc.At the same time,the communication with the PC was accomplished by the Ethernet.This system can support texts,pictures and animation to display on 256 gray-scale full-color LED screen,meanwhile it can store more data,and the data can be transmitted without the restriction of distance.
