LED full color display is a new type of indoor and outdoor large-sized electronic media, with size, good environmental adaptability, high brightness, dynamic play and so on. With the further improvement of LED cost-effective, it can be widely used in advertising, stage, signs, traffic facilities, public places. LED as a new light-emitting device, luminous characters led module installation, with a proven energy-saving features. However, the large number of LED lamps component of LED full color display application has huge energy consumption; the same time, a large number of LED modules constitute LED display, advertising light box led modules, and LED module is composed of several internal switching power supply, Henan led modules, such a large number of conventional switching power supply (without PFC correction) generate harmonic distortion can easily contaminate the public grid; therefore, electromagnetic compatibility and low power design LED display technology is an important development direction.
