Introduction

As a visual carrier of signal information, the splicing display system is used for on-site broadcast/live broadcast, emergency dispatch, on-site command, The control command center or display terminal for security monitoring and other tasks is developed in terms of ensuring the safety of large-scale events and improving the efficiency of dispatching and commanding. Play an irreplaceable role. On the one hand, according to the application requirements of different scenarios, it is widely used in the control command center and display terminal of large-scale activities. DLP and LED splicing display systems are used all over; on the other hand, with the rapid development of informatization, large-scale events often need to The signal information is quickly and effectively analyzed and visualized, which puts forward more information on the overall functional performance of the splicing display system. Claim. GA/T 1084-2013 only regulates LCD color monitors, and the scope of standard application and technical indicators are too limited. To the standard Revised, adjusted and improved the existing relevant technical index system, and expanded the scope of application of splicing walls for large-scale events to adapt to the market reality. User needs and future development trends. General specification for splicing display system for large-scale events

1 Scope

This standard specifies general requirements such as the system composition, technical requirements, test methods and inspection rules of the spliced display system for large-scale events. This standard applies to the design, manufacture, inspection and installation of spliced display systems composed of LCD, LED, DLP, etc. used in large-scale events. Installation, other scenes and other types of splicing display systems can be used as reference.
