Mini-LED has developed rapidly by virtue of its advantages in display industry, including low power consumption, stability, high resolution and display effect. In this paper, a video display system based on FPGA with multiple mini-LED displays is implemented. The system builds the circuit structure of multi-screen splicing display with FPGA and realizes the flexible splicing display of multiple Mini-LED displays, so that Mini-LED display can achieve the effect of flexible expansion of display size. Multiple video images stored in the SD card are read and segmented into parts corresponding to the number of display screens and then output to the spliced Mini-LED display screen for displaying. The main modules of the display system built by FPGA include: External storage data reading module, RAM cache module, data distribution and regulation module, RGB output module, MBI5759 module of the driver chip and infrared control module. The system is realized by using Xilinx FPGA development board and ISE development software. In addition, the corresponding PCB board is designed to connect FPGA and Mini-LED displays.
