Station, bank, supermarket and large public places of instant messaging and advertisement of the application of Chinese characters, LED display screen. In the energy crisis and information increasingly more important today, with low energy consumption, easy maintenance and update frequency of the Chinese character screen will be LED by the widespread application, it has very development prospects. In this paper, based on AT89C51 microcontroller 16 × 16LED scrolling display character design and the use of software in the simulation and realization of Proteus. Introduces the character LED display hardware design, assembly programming and debugging, Proteus software simulation and other aspects of physical production, the design of the screen is small, less hardware, the circuit structure is simple and easy to implement. Can help the fans understand the character of the lattice electronic display principle, understanding the basic structure of SCM, working principle and application of methods and technologies to improve knowledge and ability to use single chip. Keywords：microcontroller, LED dot matrix ,Proteus simulation. 目 录 要 I ABSTRACT II
