The common cathode power supply method is a technical solution based on the improvement of the common anode structure to save energy used by the LED display. It refers to the “Common Cathode” method to drive the LED display and accurately distribute the current to the R, G, and B chips.
The voltage and current first pass through the lamp beads and then to the negative electrode of the IC, reducing the forward voltage drop, and the internal resistance of the conduction becomes smaller, saving energy and reducing the power consumption and responding more efficiently.
