Anti-scratch and wear-resistant protection

With the continuous development of smart phones, in addition to the continuous improvement of mobile phone hardware, some details that we did not attach importance to previously have also undergone qualitative changes. For example, the glass of a mobile phone screen has never been concerned about it before. As long as a new mobile phone is handed, it can be directly affixed to the screen film. Now, not only is there a variety of reinforced glass, but more and more mobile phone manufacturers have begun to use sapphire glass screens. Today, let's talk about the phone's sapphire glass screen.

In fact, sapphire glass was not recently used in mobile phones. Before that, many mobile phones used sapphire glass, but instead of using a screen cover, it was a camera glass. For example, the familiar iPhone, its camera glass is Sapphire glass. In other devices, sapphire has also been widely used, and some high-end watch dial glass is made of sapphire glass.

Other luxury mobile phones are also made of sapphire glass. The most famous one is the Vertu phone. Vertu phones use not only sapphire glass, but also sapphire glass.

Sapphire glass is not what we commonly call sapphire. Sapphire glass is produced artificially. Sapphire is natural minerals. The main components of sapphire glass and sapphire are all aluminum oxide, but artificial production is much lower in value than natural, but it is still much more expensive than ordinary tempered glass.

The natural sapphire is blue, because a small amount of titanium and iron are mixed in the sapphire. In addition to the common blue, there are pink, yellow, and green. Synthetic sapphire glass will not have such a variety of colors. The synthesized sapphire crystal ingot will have a faint pink color, but after processing, the pink color will not be visible, and the finished sapphire glass screen will be transparent.

Therefore, the screen of the sapphire glass will not affect the normal display of the mobile phone, and the screen of the sapphire glass will perform better in transparency, which can make the touch of the mobile phone more sensitive.

In addition, everyone knows that sapphire glass is superior in hardness to ordinary tempered glass. Generally, the toughened glass has a hardness of 7, while the sapphire glass has a hardness of 9, which is second only to diamond. So if the mobile phone screen is sapphire glass, , then you do not need a film completely.

Sapphire glass has a lot of advantages for smart phones, so why do we not see a lot of mobile phones using sapphire glass? This is because the current production capacity of sapphire glass is far behind the production capacity of smart phones, and the cost of using sapphire glass is still relatively high. With the lower and lower prices of smart phones, the use of sapphire glass will inevitably increase the cost of mobile phones and increase the use of mobile phones. Price. However, with the advancement of technology, the future price of sapphire glass will increase, and the price will decline. The use of sapphire glass screens on smart phones is still promising.

At present, sapphire glass material is produced in a crystal growth furnace. The current production capacity is to produce 100 kilograms of crystal ingots in 18 days, and then the original sapphire ingot is cut into different sizes through processing, and processed into the final sapphire glass.

Before the iPhone 6 was released, there was news that the iPhone 6 will use a sapphire glass screen cover, but this is just rumors, in fact the iPhone 6 is still using tempered glass, if you do not film, then after a period of time will be found on the screen There will be small screen scratches.

Domestic mobile phone manufacturers are very interested in sapphire. At present, both vivo and Huawei have launched sapphire glass mobile phones, which are Huawei P7 sapphire and vivo X5 sapphire. Of course, the price is higher than the normal version. These are the sapphire glass. The cost increase. Because of the limited capacity of sapphire glass, the sapphire version of the mobile phone is currently limited. Of course, the experience brought by sapphire is certainly not the same as that of ordinary mobile phones. It does not need to be a film, and the touch experience will be better.

For most users, sapphire glass and ordinary tempered glass do not make any difference in the touch experience and display effect of mobile phones. More users still value the scratch-resistant effect of sapphire glass. Therefore, some accessory manufacturers have also launched sapphire glass. The screen film, this year's Digital World Asia Expo, Benks introduced a sapphire glass protective film, the thickness of the glass film is 0.3mm, has the characteristics of super scratch resistance, abrasion resistance, high transmittance, is the most high-end One of the mobile phone screen protection films, of course, the price is quite expensive, estimated price of 500 yuan.

At present, sapphire glass is still a luxury configuration on smart phones. It is not possible to imagine the popularity of tempered glass in the short term. Therefore, tempered glass is still the preferred choice for many smart phones for a period of time. With the increase in the production capacity of sapphire glass, the future We can also see more smartphones using sapphire glass.
