“Common cathode” refers to the common cathode power supply method. 

In fact, it is a kind of LED display energy-saving technology.

 It refers to the common cathode method to power the LED display,

 that is, the R, G, B (red, green, and blue) is supplied separately, 

and the current and voltage are accurately allocated to the R, G,

 and B lamp beads, because the R, G, B (red, green, and blue) lamp beads need the best working voltage and The currents are not the same,

 so that the current passes through the lamp beads and then to the negative electrode of the IC, 

the forward voltage drop will be reduced, and the internal resistance of the conduction will be reduced.

Using common-cathode technology, the newest and best technology for energy saving displays, 

at least 40% less of power consumption, save your costs!

960*960mm universal die casting cabinet for outdoor door display, easy to change different modules.

Power current much lower than regular outdoor display, drastically reduce heat of the modules inside and surface,

 temperature of the screen is much lower. LED is much stable and failure rate is greatly reduce.

Color consistency is much better even after years of displaying.
