After years of development, the traditional common-anode LED display has formed a stable industrial chain, however, there are also disadvantages of excessive screen temperature and high power consumption. As a result, a new technology - common cathode circuit design is emerging in the LED display industry, it has attracted great attention in the market because it can achieve energy saving of 50%.

1. What is the common-cathode LED display?

"Common-cathode" means the common cathode supplying power method, it is also an energy-saving technology of LED display.

Considering the optimal operating voltage and current required by the R, G, B led lamps are different, so the R, G, B of LED lamps are separated for supplying power in the common-cathode design, means different current voltages are accurately allocated to the R, G, B led lamps respectively, the current can be supplied to the led lamps first and then to the negative electrode of ICs, and the forward voltage drop will be reduced, therefore, the on-resistance becomes smaller.

2. What is the difference between common-cathode and common-anode LED display?

*Different supplying power methods

*Different voltages

3. What is the advantage of common-cathode LED display?

* Precise supplying power to ensure energy saving.

Based on the different photoelectric characteristics of LED R, G, B and working with intelligent ICs, the power consumption is 30% lower than common products.

*More bright colors.

The common cathode technology precisely controls the different voltage, which not only reduces the power consumption, but also reduces the heat of led display, and LED display has no wavelength shift under continuous operation to stabilize the bright colors!

* Longer working lifetime.

The low heat effectively reduces the LED damage rate, improves the stability and reliability of entire display system and prolongs the lifespan.

4. M-Shine common-cathode product: Rock Plus Series

*50% less heat than common screen, no need cooling fans.

*Bevel 45 degree designed for led cube, right angle or curved shape installation.

*Light weight 28kg/sqm. Power & signal all in 1 cable, more convenient for maintenance.

*The back of module is completely enclosed, high waterproof level IP67.

From the analysis of current development situation, the common-cathode energy-saving LED display will not increase much cost than tranditional type, also save more cost of power consumption when it works, it will definitely be respected in the market.
