摘要
大型拼接显示系统的设计需求越来越大,超高分辨率、刷新率等要求面临挑战。通过对现有技术的介绍和分析,提出了创新的设计方法,在保持一般拼接显示系统的性能基础上满足用户对超高分辨率、刷新率等要求。阐述了大型拼接显示系统设计的关键技术,即主从处理器技术和快速压缩解压技术,并提出了实现单一逻辑屏的概念。通过该系统工程的大量成功安装使用,证明了该设计方案的可行性和稳定性。该系统方案还具有较大的应用发展前景。
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.
