Shandong white LED full color display in 1993, was in Linyi full color LED display, Shandong Japan Nichia Corporation (Nichia Chemical) work Shuji Nakamura (Shuji Naka LED LED mura) Linyi LED display invention based on wide bandgap The semiconductor material gallium nitride (GaN) and indium gallium nitride (InGaN) Linyi color screen has a commercial value of the blue LED, Linyi such LED monochrome screen 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 light led display wholesale, but the white LED is rarely made out of this. LED unidirectional continuity Shandong full color LED is turned on only in one direction (power) led color display, called the forward bias (positive bias), when current flows LED display, full color electronic and Linyi hole in the inner compound to emit monochromatic light, full color price is called electroluminescence effect, and the type of semiconductor material, the wavelength of light, with their use of color and the incorporation of elements related impurities. With high efficiency, long life, unbreakable, high switching speed, high reliability Linyi LED display less traditional sources of advantage. 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.
