According to the complexity of the hardware design and the validation problem of display control without models in large and medium LED cube system, the LED cube virtual simulation model and its universal drive component model are proposed and designed using the principle of parallel projection and the modeling technology of Proteus software. The models are built by the example of 3D8 cube, and the driving timing and character pattern display are also simulated and verified. Based on the modeling method, 3D16, 3D32 and 3D64 LED cubes and driving components are designed, and the display effect of Chinese characters and point cloud models are also verified. The results show that the modeling method can reflect the operating principle of the software and the hardware for the LED cube system, as well as providing a pseudo-three-dimensional virtual visualization method for the LED cube’s design and verification. The results can provide a modeling method for the diversified show and expansion of the large and medium LED cube, and the proposed method can be used for engineering application design of three-dimensional display.
