Abstract: In order to solve the problems of the large volume of realtime data acquisition and transmission of the synchronous LED display control system , the technology of DVI interface and gigabit Ethernet was applied. And the signal bandwidth needs were put forward by calculating and analyzing . The design for the system with FPGA as the core part, DVI interface of vedio card as data sources was presented and highspeed gigabit Ethernet technology was used for realtime display data transmission, finally the practical test results were given. Results show that the module of control system meet the synchronous LED realtime digital pixel information transmission requirements.
Key words: synchronous LED display; field programmable gate array(FPGA); digital visual interface(DVI); gigabit ethernet
