Factors Affecting the Signal of LED Advertising Screens:

1、Electromagnetic Interference (EMI): Electromagnetic interference sources such as radios, televisions, lightning, electronic devices, etc., can emit electromagnetic radiation that affects the clarity and stability of the LED advertising screen signal.

2、Power Interference: Power issues like voltage fluctuations, unstable currents, power noise, etc., can lead to signal interference in LED advertising screens.

3、Signal Cable Interference: Incorrect wiring, damaged signal cables, excessively long cables, and improper connectors can all cause signal interference.

4、Wireless Signal Interference: Nearby wireless devices such as mobile phones, Wi-Fi routers, Bluetooth devices, etc., can interfere with the signal of LED advertising screens, especially in wireless communication frequency bands.

5、Electromagnetic Shielding: The lack of electromagnetic shielding around the LED advertising screen can make it susceptible to interference from the surrounding environment.

6、Signal Cable Quality: Poor-quality signal cables without shielding or improperly designed cables can introduce interference.

7、High-Current Equipment: Large current equipment running nearby, such as motors, solenoids, etc., can generate electromagnetic noise that affects the LED advertising screen signal.

8、Environmental Conditions: Extreme environmental conditions like severe weather, temperature variations, humidity, etc., can have a negative impact on the LED advertising screen signal.
