A design of biaxial-rotated RGB-LED spherical display based on FPGA is presented,which is based on the mathematical modeling with the application of vision persistence. Through the Verilog HDL programming of FP-GA,together with the design of peripherals such as LED driver, AD converter and infrared remote controller, the multiple modes of the system are successfully achieved. The combination of two control methods,which consists of remote control and manual adjustment,can improve the user’s experience. The design is valuable in practical as well as prospective application.
