Abstract: The demand of new design of large-scale display wall system is increasing，it challenged by requirements such as extra high resolution and frequency.This paper introduces innovative design techniques by stating and analyzing the existing technologies，these new techniques meet the requirements such as extra high resolution and frequency while retaining the performance of general display wall system.This paper states key technologies of large-scale display wall system，which are the technologies of structure of main/subordinate processors and fast encoding/decoding，meanwhile，introduces the idea of implementing single logic screen.The feasibility and stability of this solution is proven by lots of successful installations and uses of this system project.This system solution also has broad application and development prospect.
