The first Gan artificial 120 kg sapphire crystal in Nanchang "Optics Valley" come out, which marks the future of smart phone industry in Jiangxi Province, you can use the local made of sapphire touch screen. In addition, sapphire crystal LED lamp is also the key material production, the crystal production will further improve the industrial chain of LED lighting in Jiangxi, helping "Nanchang Optical Valley" building. "Apple's phone lens cap and home keys are supplied by us." Zhang Zhenzhi, chief engineer in charge of the project, introduced that their "sapphire crystal" will focus on the field of electronic applications such as smart phone panels in addition to targeting optical applications . As the core area of ​​"Nanchang Optical Valley", Nanchang High-tech Zone in the strengthening of silicon-based LED technology and application of research and development at the same time, vigorously the introduction of sapphire substrate LED chip manufacturing projects. According to Professor Zhang Mingfu from Harbin Institute of Technology who has been paying attention to this field for a long time, "sapphire crystal is the key material for making LED lamp. The 120kgs sapphire crystal we independently developed has broken through the numerous problems of unstable crystal growth quality and small size in the past. , Marking the sapphire crystal in Jiangxi have a large-scale production conditions. LED semiconductor lamp with energy saving and environmental protection function is the trend to replace incandescent lamp and fluorescent lamp. The development of the sapphire crystal, which means that the long-term constraints of the development of China's LED industry, "bottleneck" will be broken. According to reports, sapphire crystal is not only the key material for making LED lights, but also is an important window material used in infrared military installations, satellite space technology and high-intensity lasers. By the end of 2015, Jiangxi Province will formulate plans to build Nanchang into a national LED Optics Valley and build an LED industry chain research, manufacturing and application base with an international core competitiveness. By 2020, LED industry's main business income will exceed 100 billion yuan Yuan, accounting for 15% of the country, including silicon substrate LED technology revenue reached 50 billion yuan.
