Red light-emitting diode wavelength typically Shandong full color 650 ~ 700nm, amber light emitting diode wavelength is generally 630 ~ 650 nm, the wavelength of orange light emitting diode is generally about Shandong 610 ~ 630 nm LED display full color Shandong Linyi color screen yellow light emitting diode wavelength is generally about 585 nm full-color, 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 Linyi full color, see Table 4-26, Table 4-27 and Table 4-28. White LED Shandong full color 1993 indoor full color, full color Linyi was Nichia Corporation in Japan Shandong LED display (Nichia Chemical) work Shuji Nakamura (Shuji Naka LED LED mura) Linyi LED display invention based on the wide gap semiconductor materials gallium nitride (GaN) and indium gallium nitride (InGaN) Linyi color screen has a commercial value of the blue LED, Linyi monochrome screen this type of 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.
