Best answer

The color of the LED display power cord usually follows certain standards to represent the positive and negative poles. 

In most cases, the color of the power cord is consistent with the positive and negative pole identification in the electronic components for easy installation and maintenance.

The following is a detailed introduction to the color representation of the LED display power cord:

Power cord color identification

Positive: Red is usually used to represent the positive pole, and sometimes VCC (+) is also used to mark it. Red is a widely recognized positive pole identification color in the electronics industry, which clearly indicates the positive flow direction of the power supply.

Negative: The negative pole is usually represented by black, and sometimes GND (-) is also used to mark it. Black, as the identification color of the negative pole, forms a sharp contrast with red, which helps to avoid wiring errors.

Other possible color identification

Although red and black are the most common power cord color identifications, other colors may be used to indicate the positive and negative poles in some special cases. 

However, these non-standard colors are not common in the power cord of LED displays. 

If you do encounter a non-standard color power cord, it is recommended to refer to the product manual or consult the manufacturer for accurate wiring information.

Wiring precautions

1. Accurately identify the color: Before wiring, be sure to accurately identify the color of the power cord to ensure the correct connection of the positive and negative poles.

2. Follow the wiring specifications: Follow the wiring specifications provided by the product manual or the manufacturer to ensure the firmness and safety of the wiring.

3. Use professional tools: During the wiring process, professional wire strippers, wire crimpers and other tools should be used to ensure the quality and reliability of the wiring.

4. Check the wiring: After the wiring is completed, carefully check whether the wiring is firm and correct, and whether there are safety hazards such as short circuits.

Conclusion

In summary, the positive pole of the LED display power cord is usually indicated by red, and the negative pole is indicated by black. 

This is a standard color identification widely recognized in the electronics industry, which helps to ensure the correct connection of the power cord and the normal operation of the LED display. 

During the wiring process, be sure to follow the relevant specifications and precautions to ensure the quality and safety of the wiring.
