G, B (red, green, blue) lamp beads required by the best working voltage and current is not the same, so that the current will first go through the lamp beads and then to the IC cathode, the forward voltage drop will be reduced, the on-state internal resistance will become smaller.Ĭommon cathode power supply method, as mentioned above, is by the current first through the lamp beads, and then to the IC cathode, so that the forward voltage drop becomes smaller, the conductive internal resistance also becomes smaller. “Common Cathode”, refers to the common cathode power supply, in fact, is a led display energy-saving technology, refers to the use of common cathode way to power the led display, that is, the use of led beads R, G, B (red, green, blue) to separate the power supply, accurate respectively for R, G, B beads to allocate current voltage, due to R, G, B (red, green, blue). Only now, as the industry chain and technology products continue to mature and stabilize, and the cost decreases, it really makes the common cathode rgb led display into the public view. In fact, “common cathode” is not a brand-new technology, some of the industry’s screen enterprises in the early years of “common cathode technology indoor small pitch products” has been widely used in national key projects, and now with the industry chain and technology products continue to mature, stable, as well as cost reduction. LED display using common cathode technology, its energy-saving effect can reach 30% to 75%, greatly reducing the power consumption, and can save a lot of electricity expenses every year. Please contact to our support team at for any question related to shipping.Conventional common led display has been through the years, has constituted a stable industry chain, driving the application of led display, with the development of the economy, the market requirements for led display size is getting larger and larger, using conventional led display to splice the large screen will have a lot of power consumption, every year to pay a lot of electricity costs.
