LED luminous efficiency (that is, external quantum efficiency) is within the LED quantum efficiency and the escape rate decision. Today, LED internal quantum efficiency is as high as 90%, but due to the escape rate is low, and therefore enhance the external quantum efficiency of LED light effect become a bottleneck. In order to break the bottleneck restricting the development of the industry, many innovative solutions have been proposed led display prices, while the theory has been verified, most of which have entered the test phase, and some have been successful full color led display, and for the final industry has laid a solid foundation. 8. The back of the box protection class up to IP65. (Optional) 9. support more high-end IC can improve the display of grayscale and refresh rate, and to ensure that after prolonged use of the display brightness can meet the demand. (Optional) 10. Large angle design, up and down about 120 degrees. (Optional) Maintenance 11. The front design, no maintenance channel, effectively reduce the screen thickness. (Optional) 12. 10,000 of brightness designed to meet the needs of most high-end users. (Optional) 13. a fully automated production process, improve the reliability and stability of the product. 14. The materials used sophisticated indoor led display, ensure high temperature, low temperature, high humidity environments. 15. Before the factory strictly controls the quality, subject to aging, waterproof, vibration and other rigorous testing to ensure the factory zero failure rate. led display _ Gao Jin photoelectric _led display provided by Jinan Gao Jin Optoelectronics Technology Co., Ltd. led display _ Gao Jin photoelectric _led display is Jinan Gao Jin Optoelectronics Technology Co., Ltd.
