LED display is the LED module or in accordance with the actual needs of the size of the pixels arranged in a matrix assembly, together with the special show circuit, DC power supply, software led display control software, frameworks and outdoor decoration, constitute an LED display . What is LED? In certain semiconductor materials, PN junction led display price, the injected minority carriers and majority carrier recombination, when will the excess energy released in the form of light, which converts electrical energy directly into light. PN junction reverse voltage, minority carrier injection is difficult, it is not light. This use of injection electroluminescent diodes called the principle of making light-emitting diodes, known as LED. _ 金锐光 Wufeng led display screen provided by the electric _led Technology Co., Ltd.
