This paper discusses the development history and trend of LED display screen. It describes the composition of LED display screen system and the realization functions of each part. The key parameters which determines the performance of LED screen are listed and the model of LED screen size and specification selection is put forward. Then the key indicators and related factors that affect the selection results in this model are determined. At last,the impact on the benefits of LED screen when the key factor changes is analyzed,which provides a reference and comparison for intelligent system designers.
