Have mosaics, dead phenomenon: Mosaic refers to the color of modular units appears on the display effect is uneven, lit or normally black small four-square, both modules necrosis, mainly used for the display The connector quality, but off. Always referring to the dead appear on the screen or normally black single point, how good or bad from the die to determine the dead point. Have mosaics, dead phenomenon: refers to the color mosaic of modular units appears on the display effect is uneven led display repair, lit or normally black small four-square, both modules necrosis, mainly due to connectors used for the display quality, but off. Always referring to the dead appear on the screen or normally black single point led display, how much good or bad from the die to determine the dead point. Red A1GaAsLED compared with GaAsP-GaP LED, has a higher luminous efficiency led display manufacturers, low transparent substrate (TS) A1GaAs LED (640nm) of the luminous efficiency is close to 10lm / w, than red GaAsP-GaP LED 10 times . InGaAlP LED provides high brightness of color and GaAsP-GaP LED same include: green-yellow (560nm), yellow light green (570nm), yellow (585nm), light yellow (590nm), orange (605nm), light red (625nm Crimson (640nm). Comparison with other luminous efficiency of the LED structure and incandescent light transparent substrate A1GaInP LED, InGaAlP LED absorbing substrate (AS) of the luminous efficiency of 101m / w, transparent substrate (TS) of 201m / w, at 590 than GaAsP-GaP LED's luminous efficiency of the wavelength range -626nm 10-20 times higher; in the wavelength range 560-570 of the higher than GaAsP-GaP LED 2-4 times as high brightness InGaN LED provides the blue. shade and green light, the blue wavelength range of 450-480nm, blue green 500nm, green 520nm; its luminous efficiency is 3-151m / w high brightness LED's luminous efficiency more than the incandescent band filter. lamp, incandescent lamp can replace the power 1w or less, and can replace incandescent lamps with LED arrays 150w power within. For many applications, the use of filters to get all incandescent red, orange, green and blue, and with super you can get the same high-brightness LED color .AlGaInP materials and materials of high brightness InGaN LED plurality (red, blue, green) ultra-high brightness LED chips together, without filters can get a variety of colors .. full color led display, 金锐光 electricity (certified), led by the Yichang 金锐光 Display Technology Co., Ltd. Yichang 金锐光 Technology Co., Ltd. (www.ycjrgd.com/) Hubei Yichang, electronics, Electrical project co-leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In 金锐光 power leadership with the staff warmly welcome all inquiries negotiations to create 金锐光 electricity a better future.
