White LED Shandong full color led display 1993 Shandong Linyi full color was Nichia Corporation in Japan Shandong LED display (Nichia Chemical) work Shuji Nakamura (Shuji Naka LED LED mura) Linyi LED display invented based on a wide bandgap semiconductor material gallium nitride (GaN) and indium gallium nitride (InGaN) Linyi color screen has a commercial value of the blue LED display, monochrome screen such Linyi LED in the late 1990s are widely used full color display manufacturers. Theoretically blue LED combined with the original red LED and green LED can produce white, but white LED is rarely made out of this. Voltage controlled light-emitting diode LED (light emitting diode) LED (Light Emitting Diode) Shandong full color ordinary light-emitting diode is a current-controlled device bus led display, the use of an appropriate current limiting resistor required in series resistance. Linyi LED display voltage controlled light-emitting diode (BTV) is a light-emitting diode and current limiting resistor integrated production as a whole, when Shandong LED display can be directly used and connected across the power supply. So that ordinary red light emitting diode voltage can work as YX503URC, YX304URC, YX503BRC voltage type LED light-emitting diode, the engineering and technical staff to provide greater choice in 3 volts -10 volts. led display, Yasuhiro photovoltaic (certified), Yantai display by Linyi Wang Tai Electronics Co., Ltd. Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) is a leader in Linyi, a display device, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In Hong Thai Optical leadership with the staff warmly welcome all inquiries negotiations to create the Thai macro photoelectric a better future.
