Substrate from the Chinese industrial development situation, at the National Semiconductor Lighting Project, 863 and other major projects with the support of China prepared red, green LED Tube with a substrate technology has made significant progress. Distribution in the enterprise, in Section gallium Britain, Kwok Shui electronics, in Kejia Shanghai Pu, China Electronics Technology Group Institute 46 companies have achieved the bulk supply of these products. LED substrate production of these enterprises have occupied the whole LED substrate production in China about 30%, in order to protect the Chinese basically independent of the type of substrate supply.

In 2010, for the used blue, white LED growth sapphire substrate, SiC substrate and GaN substrates by downstream LED Light backlight and LED lighting market, driven by rapid growth, GaN epitaxy / chip rapid expansion of production capacity, making the upper substrate short supply, pushing prices continue to rise. Although the domestic industry's performance of such substrates and yield is still low, the growth of such substrate materials is also more a lack of professionals, however, driven by higher industry profits in 2010, Chinese enterprises have started to intervene or that involved in the field of sapphire substrate, gradually expanded capital investment and technology transfer related to the key.Guiyang City, Guizhou Province Investment Industry Corporation (Guiyang workers to vote). Among them, the competition law in Tianjin, Qingdao Jiaxing Jing electricity, Audemars Piguet, Shenzhen and other companies have begun to supply Stone sapphire substrate, the four groups in 2008 is well-known manufacturers by the acquisition of Honeywell International in Canada, the sapphire substrate factories and related technologies into the sapphire substrate area. To further expand their territory, the establishment of Chongqing Silian Group sapphire substrate is the LED Bulbs base, as of the end of 2010 Silian Group sapphire substrate project is progressing well, the project one has entered the commissioning phase equipment, some capacity has been released. Yunnan aquamarine, optoelectronic and other enterprises HIT Ao Ruide boule growth of self-control techniques, the sapphire substrate has been achieved small-scale production. GCL optoelectronics, photovoltaic Eurasian Sapphire, Tiantonggufen in 2010 also began to enter the field of sapphire crystal rod and the substrate. Zhejiang optical crystal, optical Anrui SG Xi'an in 2011 is ready to commence the layout, Zhejiang Jiang Dongjing e "with an annual output of 7.5 million LED sapphire wafer technology projects," a volume production planned for late 2012. Overall, according to the downstream industry capacity expansion, at least the next three years sapphire substrate supply to remain tight in the Chinese sapphire industry starting in 2011 will quickly attract investment, expand production, industrial output value in the LED spotlight substrate will share expanded rapidly and exceeded the quaternary products.
