  LCD splicing screenThe application of LCD splicing screens has become popular in various industries in our daily lives. Now, we will analyze in detail some common problems and solutions we encounter in the daily use of LCD splicing screens. Signal interference is a common issue we often encounter during the installation and use of LCD splicing screens. Now, we will conduct a systematic analysis and troubleshooting of the common signal interference in LCD splicing screens: signal interference is mainly caused by the power supply of the power supply system; Space radiation interference introduced by transmission lines; Faults caused by short circuits or open circuits between the core wires of video cables and the shielding mesh; The quality of the video transmission line is poor; There are strong sources of interference near the system.

If it can be determined through investigation that signal interference is caused by the power supply of the power supply system, then we only need toLCD splicing screenThe entire system can be basically solved by using purified power supply or online UPS power supply. One solution to the spatial radiation interference introduced by transmission lines is to have an understanding of the surrounding environment when establishing the system and try to avoid or stay away from the radiation source as much as possible; Another method is to strengthen the shielding of the front-end and central equipment when it is impossible to avoid the radiation source, and to use steel pipes and good grounding for the transmission line pipelines.

The fault caused by short circuit or open circuit between the core wire and the shielding network of the video cable often occurs on BNC connectors or other types of video connectors. When this fault phenomenon occurs, the LCD splicing wall often does not have problems with all signals of the entire system, but only appears on the number of poor connectors. As long as these connectors are carefully checked one by one, they can be solved. There are strong sources of interference near the system. This can be judged through investigation and understanding.
