Which is the most powerful listed company that manufactures sapphire in China?

Recently, the demand for sapphire has surged, and the production capacity of companies such as Zhaoyuan and Jiajing in Taiwan Province Sapphire Factory has reached full capacity. At the same time, Zhaoyuan has started to raise prices for some customers, and plans to raise prices on a large scale in the near future, and listed companies in the domestic sapphire industry chain will also benefit from it. The reasons for the great increase in demand include the explosion of LED lighting demand, the emergence of new applications such as the rear lens protection glass of smart phones and the Home key fingerprint sensor. Sapphire will be applied to the screen protection cover of mobile phones in 20 14, and the market capacity will increase instantly by10 billion USD. In September of 20 13, Apple first applied sapphire to the Home key case of the iPhone 5s. Compared with the previous camera cover, the amount of sapphire has increased by ten times. Since then, Apple has signed a $578 million supply contract with an American manufacturer of sapphire crystal bars. The market predicts that the iPhone 6 launched by Apple in the third quarter of 20 14 is likely to use sapphire as the screen protector of the whole screen. Moreover, Apple may launch a large-size mobile phone, which will greatly increase the demand for sapphire. According to IHS forecast, the demand for sapphire by smart phones and other smart terminals will increase from 5% in 20 12 to 20% in 20 14.
