At the Apple iPhone 12 announcement event, a surprise-less rumor-was announced with the new technology "Ceramic Shield" used for the glass on the screen side.
This is a new technology installed in all four iPhone 12 series models (MUJI and mini, Pro and Pro Max), which makes the glass more durable against scratches and impacts. Apple's appeal states that it is "four times more durable against drops than the iPhone 11 generation."
The iPhone series was a model that relatively often sees the so-called "glass cracking" state, with the help of the structure that the touch panel reacts even if the surface glass breaks. It seems that generations will be less likely to carry such sadness.
For technical details, on the official page of the iPhone 12 series, he introduced that "nanoceramic crystals were injected into the glass surface on the screen side." Basically, the impression you get from words is the same, and it seems that you can recognize that fine ceramics protect you from scratches and impacts.
However, the technical point was how to maintain the transparency as screen glass because ceramic is not transparent.
Apple says, "By controlling the type of crystal and the degree of crystallization, we have developed a special formulation that maximizes the strength of the ceramic while maintaining high transparency."
Apple is proud of its uniqueness and impact resistance, saying, "It has never been used in any other smartphone, and it is stronger than the glass of any smartphone."
In addition, consideration is given to resistance to minute scratches that conflict with drop durability. It is clear that the technology "double ion exchange process" that enhances the scratch resistance of the glass, which was used only for the back glass in the conventional iPhone, has also been adopted for the screen side glass.
This technology claims to protect the glass from scratches, scratches and daily wear.
And in the iPhone 12 series, we also introduced ingenuity in the main body design to improve drop resistance. That is, the cover (exterior) and the edge of the body are at the same height.
In other words, the (so-called) 2.5D-processed surface glass that was characteristic of the conventional iPhone series has been abolished, and the exterior frame and glass surface have become flat.
By combining these ideas, we have achieved the nominal "4 times higher drop resistance of the main unit compared to the iPhone 11 generation". In addition, this value of 4 times is also the largest improvement rate in iPhone history in the impact resistance comparison with the previous year's model (measured internally by Apple).
At the recital, there was also a scene where the durability was appealed as "Oops Resistant" -in other words, "inadvertently protected" -in addition to waterproof and dustproof performance.
This consideration for impact resistance is a point that was emphasized in the iPhone 11 series (perhaps as if it overturned the public image of the iPhone so far), but in the iPhone 12 generation, this point is also We showed further consideration-and introduced it to all models in the series, not just the higher-end models-which is a great pleasure for users.
From this year, we can expect that the probability of seeing an "iPhone with a fluttering screen" will decrease.
