Knowledge & Support

A Common Cathode LED Display is a type of LED screen that uses a unique power supply method where the positive (anode) terminals are separated, and all red, green, and blue LEDs share the same negative (cathode) connection.

This architecture allows for independent voltage and current control for each color channel, resulting in better energy efficiency and lower heat generation compared to traditional common anode designs.

Key Advantages of Common Cathode LED Technology

✅ Energy Efficiency: By supplying just the required voltage to each color, especially the red channel (which typically needs lower voltage), common cathode LEDs can reduce power consumption by up to 30–40%, making them a perfect choice for Low Power Consumption LED Screens and Energy Saving LED Displays.

✅ Less Heat, Longer Life: With reduced power loss, there is less heat generation, leading to longer component life and more stable operation—especially in outdoor LED screens and high-brightness LED walls.

✅ Better Color Accuracy: Independent control over RGB currents allows more precise color tuning, which enhances image quality in Indoor LED Displays, COB LED Displays, and Fine Pitch LED Screens.

✅ Improved Environmental Performance: Combined with technologies like Aluminum Module LED Screens, Solar-Powered LED Displays, and Lithium Battery-Powered LED Screens, common cathode systems support green energy solutions in digital signage.
