Design of LED Display Control System Based on AT89C52 Single Chip puter
Abstract—This paper introduces display design processabout hardware and software based on AT89C52 single puter. We use a simple external circuit to controlthe display screen, which size is 32 × 192. The display screenalso can display the size of the six 32 × 32 dot matrix Chinese characters by a dynamic scan mode, and can be divided into two small display screen, which can display twenty-four Chinese characters whose size is 16×16. We can modify the code to change the content of the display,subtitles can achieve scrolling function and the scroll speed can be adjusted according to requirements, subtitles can also achieve pause function. The Chinese character code stored in external data memory, the capacity of data memory is expanded according to the requirements of Chinese characters we want to show. This display screen has advantages of small volume, few hardware and simple circuit structure.

I. INTRODUCTION
LED display has e an important symbol of the city lighting, modernization and information society with continuous improvement and beautification of people's living environment [6]. LED lights can be seen in the large shopping malls, railway station, docks, underground station, a variety of management window and so on. LED business has e a fast-growing new industry, a huge market space and bright prospects [9]. The text, pictures, animation and video are displayed by LED’s light, and content can be changed. ponents are the display devices of the modular structure, and which usually consists of a display module, control system and power system. The display module is constituted by the lattice structure which consists of LED, and is responsible for light-emi
