Currently mosaic screen widely used, more used video surveillance, dispatch centers, bars and entertainment industry, because the realization of large-screen LCD splicing LCD splicing technology is the result of splicing, and then through signal reception and signal processing for the screen display, but signal interference often occurs during the installation and use, this is why?
Shenzhen Nanor professional engineering staff for you to resolve the problem of signal interference mosaic screen:
1. What circumstances caused by signal interference?
There are signal interference caused by these types of situations: the power supply system caused; transmission line into the space radiation interference; video cable with shielded core wire short circuit caused by the failure; poor quality of the video transmission line; near the system strong interference sources.

2, troubleshoot and resolve interference
If during the investigation of the above, the power supply system cause, it is necessary for the system to use the LCD splicing screen or on-line UPS power supply clean power to basically be resolved.
If the space radiation interference introduced by the transmission line, then you need to understand the surrounding environment, as much as possible try to avoid or away from the radiation source, it can also be shielded front and center equipment, pipeline transmission line for steel pipe and well grounded.
If the video cable shielded core wire and short circuit, then this situation that happens more often in the BNC connectors, or other types of video connectors, so check joint look at the whole system is a bad situation.
If there is a strong source of interference near the system, we need to understand the surrounding system in order to determine if this is the case, to strengthen the shield of the camera, and the video cable pipes in the ground processing.
Nanor note: If the above conditions are not resolved, then please contact the manufacturer to resolve LCD screen splicing, formal manufacturers have technical staff support necessary even if you can arrange on-site inspection and maintenance, regular manufacturer's service must be guaranteed. Remember not secretly DIY users and open the LCD splicing screen, so as to avoid damage to the LCD panel mosaic screen, so it is in trouble.
