Abstract: To meet the needs of small and medium businesses, a remote control project for LED text display screen with a low cost and easy content updates was designed in this paper. A MCU was used as processing core and GPRS/GSM communication standards were adopted in this system. The control commands and display data emitted from a phone were received by GPRS module mounted on the screen. The received data were then processed to control scan display of the LED screen. Remote update display contents on the LED screen were realized finally. After a period of practical use, the system operation is stable and reliable, and achieves design requirements.
