AbstractLED screens have become a musthave for modern largescale sports venues and are indispensable equipment for major sports events. Therefore, the application and development of LED display in the field of sports are studied. The LED dot matrix is selected as the display system of the automatic track circle system of the sports track competition. By analyzing the display principle of the display screen pair code and Chinese characters applied in the sports field, an algorithm is proposed to develop the application of the display screen in the sports field for the sports field. The application display provides a reference for character and Chinese character display. The debugging result is consistent with the expected goal, and the number of displays and the number of additions and subtractions can be realized by keyboard operation, and the remaining number of laps of the athlete is correctly displayed.
