"Common cathode"is actually an energy-saving technology for LED display.Due to the different working voltages and currents required by the R ,G,B (red,green,blue)lamp beads, the current in the common cathode power supply mode will first pass through the lamp beads and then to the IC cathode .Reduce the forward voltage drop,reduce the on-resistance,and achieve the purpose of energy saving.
