The principle of space-time division of the rotating LED display screen and the overall design scheme are briefly described. The functions and working principle of each part of the electronic circuit and the display section of the rotary display screen, which is designed by using FPGA, are mainly introduced. The signal is converted to light-emitting diode display process. Aimed at the high-speed rotation of the rotary display, the data transmission capacity is high and the speed is high, a display controller based on FPGA is designed. By using FPGA to control the display gray of the LEDs, 256 levels of rotary light-emitting diode display Grayscale display. The experimental results show that the rotary display made by the method can correctly display the transmitted information content, the system can save a large number of light-emitting diodes and has low cost and is a cheap and efficient new technology product.
