The iPhone 13 leaves the factory without a film. The box only contains the phone, a USB-C to Lightning cable and information. The phone case, film and charging head need to be purchased by yourself.
The screen of a mobile phone is mainly composed of three parts: cover glass, touch module and display module.
When it comes to cover glass, Corning has to be mentioned. From the first generation iPhone to the iPhone 11, the iPhone used Gorilla Glass from Corning; while the iPhone 12 and 13 series used higher quality super ceramic panels.
The super ceramic crystal panel newly introduces nano-scale porcelain crystals that are harder than most metals, making them integrated with the glass. In addition, thanks to the flat rounded middle frame design and super ceramic crystal panel, the drop performance of the 12 and 13 series is four times that of ordinary glass.
There are also many differences in repairing broken mobile phone screens. Official after-sales service generally replaces the entire screen, while many third-party repairs only replace the outermost glass. Cover (not a super ceramic panel), so its anti-fall performance is far inferior to the original super ceramic panel or Gorilla Glass, which is why the screen has been broken only 0 and countless times.
There are more and more appearance designs of mobile phones, and the functionality and types of mobile phone films are becoming more and more abundant. In addition to the most common tempered film, there are also anti-peep film, anti-blue light film, frosted film, high-permeability film, hydrogel film, etc. The tempered film is not only anti-fall but also anti-scratch. When the tempered film is impacted, the tempered glass will absorb part of the kinetic energy by breaking itself, thereby reducing the impact on the screen; the tempered film can also prevent the mobile phone screen from being scratched by hard objects, sand, etc.
In addition, in most cases, when the phone is dropped, the probability of the corner touching the ground first is much higher. It may be said that wearing a protective case is also a more important way to protect the phone screen from shattering.
Anti-peep films, for example, have a certain effect. Through the patented optical technology of ultra-fine blinds, the information displayed on the screen is exclusively for users to read from the front. Anyone watching from both sides can only You can see a dark screen. However, the anti-peep film will greatly reduce the brightness of the mobile phone, and the power consumption of the mobile phone will also be significantly increased after the brightness is increased.
Mobile phone screen protectors are still an indispensable and important accessory for mobile phones. Anti-peep, frosted and other functions can be selected according to needs, but anti-blue light has no actual effect.
