R = (E-UF) / IF where E is the supply voltage, UF display Wholesale LED's forward voltage drop is led, Shandong full color LED IF the normal operating current. A core part of Linyi LED display light-emitting diode is a semiconductor wafer by a P-type and N-type semiconductor in between the P-type semiconductor and N-type semiconductor between a transition layer, called the PN junction. Shandong full color display in certain semiconductor materials, PN junction, Shandong full color injected minority carrier and majority carrier recombination, when will the excess energy released in the form of light, full color so converts electrical energy directly light energy. Linyi LED display PN junction reverse voltage, color screen minority carrier injection is difficult, it is not light. Shandong white LED luminous efficiency LED display, LED display Linyi in recent years has significantly improved, while the LED display, Shandong full color on the purchase price per thousand lumens, Linyi full color into the market because manufacturers competing influence, but decreased significantly. Linyi color screen, although more and more people use LED lighting for offices, furniture, decoration, Shandong Full Color prices even street signs use, but technically, the photoelectric conversion efficiency (effective illumination of the electricity consumption ratio) on the LED remains Linyi below the new fluorescent display manufacturers, the country's whereabouts after the development of civil Shandong full color display manufacturers. Bus led display, Liaocheng display, provided by the Thai macro photoelectric Linyi Wang Tai Electronics Co., Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) strong, credible, in Linyi display equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Hong Thai Optical into the brilliant and you work for a better future!
