FPGA-based LED Display Technology

The paper introduces a LED display based on FPGA hardware circuit and VHDL language to function multiple-character scrolling display. The hardware is composed of power supply circuit, FPGA core board and LED dot-matrix driver module; the Intel® Quartus® Prime Design Software is used to edit the download configuration document by programming with VHDL language, compilation, synthesis and optimization. The test proves that the the content "Electromechanical sichuan agriculture and information technology " displayed by the LED display is artistic and right.
