| Abstract: | 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. |
