LED unidirectional continuity Shandong full color LED is turned on only in one direction (power), called the forward bias (positive bias), when the current flows, Linyi full color electrons and holes in the inner compound and emit monochromatic light, full color price effect is called electroluminescence full color manufacturer, and the type of semiconductor material wavelength of the 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. Red light-emitting diode wavelength is generally 650 ~ 700nm Shandong full color hotel full color, amber light emitting diode wavelength is generally 630 ~ 650 nm Jiangsu full-color, orange light emitting diode wavelength is generally about Shandong LED display 610 ~ 630 nm, Linyi color screen yellow LED wavelength is generally about 585 nm, Linyi LED display green LED wavelength is generally 555 ~ 570 nm. Hotels full color commonly made ordinary monochromatic LEDs have BT (factory standard model) series, FG (Ministry of standard model) series and 2EF series, Table 4-26, Table 4-27 and Table 4-28. Jiangsu full-color, Yasuhiro photovoltaic (certified), Zibo Linyi full color provided by the Thai-Hong Electronics Co., 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.
