Mobile phone sapphire screen will be put into mass production within one year

From June 26th to 28th, 2013, the annual Asia Mobile Communications Expo (gsma2013) was held at the Shanghai New International Expo Center. As the “first show” of new products and technologies in the mobile phone industry, this exhibition attracted famous mobile phone manufacturers such as Lenovo, BBK vivo, Samsung, Sony and Huawei to display the latest mobile terminal products and cutting-edge technologies. At the same time, China Mobile, China Unicom, China Telecom's three major operators and visa, rovio, app lab, etc. all made their debut.

If it is in the category of mobile Internet terminals such as mobile phones or tablets, the second option that can compete with the Corning "gorilla" glass screen for some time, I think there may be only sapphire. If you are also plagued by scratches on your phone screen, be sure to focus on the next-hardest sapphire, which is second only to diamonds. It is likely to form a fierce competitive relationship with Corning Gorilla Glass in the next year or so. .

The two prerequisites for sapphire and Corning Gorilla Glass can be compared. One is cost and the other is capacity. These two aspects will make us see huge in the next year to a year and a half. Market competitiveness.

From the hardness level, according to the Mohs hardness coefficient, sapphire has a super hardness that is second only to diamond (diamond), which is a disadvantage of glass material at this point. In other words, if it is a mobile phone with a sapphire screen, even if the user does not attach any protective film, there is no need to worry about the fine scratches caused by fine sand, particles and the like.

Listening to the virtual, seeing is believing, we use a video to witness how high the hardness of sapphire is. The Apple iphone5 screen used for the demonstration has a custom-made sapphire protective layer. It can be seen that even if it is repeatedly "destroyed" with sharp stones, the sapphire layer is not damaged. In addition, including the grease and perspiration of the fingers and face, for sapphire, it is also only necessary to gently wipe.

It has just been mentioned that sapphire is not a new technology. It existed 100 years ago. The reason why it can be applied to mobile phones and other devices (such as vertu luxury mobile phones) is mainly because the cost is too high. And the yield is not high (bubble is easy to appear in the crystal). However, with the continuous advancement of technology, today's sapphire is very mature, and with the help of international advanced technology, it can fully guarantee the production capacity of the crystal. However, in order to promote the entire industry chain, it is also necessary to coordinate the cooperation between material suppliers and terminal manufacturers. This work is expected to be completed within a year or so.

The dielectric constant of sapphire is 30% higher than that of glass. In theory, it is more sensitive to touch screen. It is foreseeable that sapphire will definitely present the product in a short period of time, and the glass material will not be replaced, and the two will remain coexisting for a long time.
