Traditional LED display is of great power consumption, especially the outdoor advertising screen, which is incompatible with the carbon reduction requirements. Therefore, LED display products with common cathode power supply technology appeared, such as COB. The advantage of common cathode technology is lower power consumption and energy saving, making the light-emitting diode more stable and achieving a longer lifespan. So that's why the picture is ultra-high-definition,
stable and has no split screen.
