摘　　要：概述了中国下一代互联网示范工程运行演示中心大屏幕显示系统从建设到运行过程的技术要点。在设计方面,重点比较了液晶显示单元的背光源技术和显示墙控制器的关键技术指标,实现了良好的系统总体性能;在实施方面,采取了系统控制部分建立与互联网隔离的私有网络等措施,保障了系统安全;在运行方面,通过软件实现了显示内容与系统信道对应关系的简单管理,从而显著缩短了故障恢复时间,提高了显示内容部署的灵活性。This paper outlines the main technical points about the construction and operation of the large-screen display walls,which belongs to the CNGI Network Operation Center.In design,after comparing the key technical indexes of the LCD backlight technology and the display wall processors,a system with good overall performance is achieved.In implementation,by means of setting up a private network which is isolated from the Internet,security of the system is ensured.In operation,by means of the software and systems to simply manage the correspondence between the display contents and the system channel,the recovery time due to common failure has been significantly reduced and the flexibility of deploying the display contents has been increased.
