More and more places in shopping malls, railway stations, docks, subway stations and a variety of work window LED dot matrix display graphics and characters. LED industry has bee a fastgrowing emerging industry, a huge market space and broad prospects. With the rapid development of the information industry, LED display has been widely used as an important means of dissemination of information, content and services aim to promote the need for indoor and outdoor public places, such as indoor and outdoor advertising in public places, the airport station visitors guide bus stop vehicles, securities and banking information display, restaurants offer information beans shown, highway variable information boards, stadiums the games, building lighting, traffic lights, landscape lighting. Clearly, LED display has bee an important symbol of the city lighting, modern information society. Monolithic is an integrated circuit chip, is the use of ultralargescale integrated circuit technology with the data processing capabilities of the CPU random access memory RAM, readonly memory ROM, and a variety of I / O port and interrupt system, the timer / timer other functions (which may also include the display drive circuit, the pulse width modulation circuit, the analog multiplexer circuit of the a / D converter, etc.) are integrated into a small piece of silicon is formed on the puter system. The Monolithic is widely used in the field of intelligent management and process control, instrumentation, home appliances, medical equipment, aerospace, specialized equipment. This article is based on singlechip LED scrolling the English display design, just a simple application of singlechip, it can achieve a variety of functions displayed. Briefly introduced the principle of English through the Monolithic to control the LED display shows, as well as hardware circuit and software design, and I hope to help the majority of electronics enthusiasts display principle of English, understanding the basic structure of the Monolithic, working principle and application methods, and improve the Monolithic abi
