Apple’s iPhone 12 line comes with a new protective glass coating called Ceramic Shield. Ceramic Shield promises 4 times better shatter resistance than previous-generation iPhones, clear optical performance and scratch resistance is generally okay. In the past, iPhone screens were often not too prominent in terms of scratch resistance and shatter resistance. So this looks like a pretty important improvement.
So how exactly did Apple implement this new glass technology and what advantages and disadvantages does Apple have compared to other technologies on the market?
For those who do not know, Ceramic Shield is a new glass technology from Corning, the main manufacturer of Gorilla Glass screen protection.
To better understand this technology, Apple has made a pretty important suggestion, that is “ceramic crystal”.
Small ceramic nanocrystals are embedded in a glass matrix by a high-temperature crystallization production process. The interwoven structure of the crystals helps to deflect cracks.
Corning also strengthens glass through ion exchange (increasing the size of ions to create a stiffer structure) that helps the glass stick together more firmly even under strong impact and reduces the appearance of scratches.
According to Corning, “Ceramic Shield is harder than any smartphone glass today”. Meanwhile, Apple claims Ceramic Shield offers four times more drop resistance than previous iPhone models.
The main benefit of this type of glass is to minimize the risk of cracking, scratches, and increase hardness. However, ceramics often do not have as high a transparency as ordinary glass. In the past, ceramic glass has been used on the back of the Samsung Galaxy S10 Plus but it is rarely used as a protective glass for the screen as well for this reason.
However, thanks to the use of ceramic crystals smaller than the wavelength of light, the Ceramic Shield has a very high transparency, which is suitable for the screen protection of the iPhone 12.
So how is Ceramic Shield different from Gorilla Glass Victus?
The big difference between the Ceramic Shield and Victus is in the material. Victus is a reinforced alumino-silicate glass rather than a glass ceramic. Alumino-silicate glass is known for its low weight, high scratch resistance and extreme hardness. That makes it the ideal material for a smartphone screen protector.
These glasses are also resistant to high temperatures and chemical breakdown, though these properties are rarely seen on smartphones.
Victus is drop resistant up to 2 meters even on rough surfaces. Victus’s scratch resistance is also 2 times higher than Gorilla Glass 6 and 4 times more resistant to rival glasses. What’s impressive about Victus is that it possesses improved rigidity but no increase in thickness compared to previous generations.
Even Corning can’t share the difference in terms of specific strength and scratch resistance between the two.
However, Corning stressed that “Gorilla Victus is the toughest Gorilla Glass ever made by the company.” Galaxy Note 20 Ultra and Galaxy Fold 2 are both equipped with Victus glasses and it is likely that many smartphones released in 2021 will have these glasses.
Without direct comparison, it will be difficult to know which glasses can best resist drop. But whether your smartphone uses the latest Ceramic Shield or Gorilla Glass, it is increasingly resilient to the impressive impact and scratch resistance.
