In line with the story, simply six weeks earlier than the unique iPhone was launched, CEO Steve Jobs acquired upset that the plastic display screen of the prototype machine he was utilizing had been scratched. A final minute change subsequently noticed Apple change to glass.
And never simply any glass, however Gorilla Glass. This chemically strengthened glass was created by Corning and has since grow to be a staple within the smartphone market. Let’s first have a look at a little bit of historical past earlier than we get to the period of smartphones.
Corning acquired its begin within the mid-Nineteenth century, manufacturing lenses for railroad sign lights and later automotive headlights. He made the glass for Thomas Edison’s gentle bulb. In 1915, she created Pyrex kitchen utensils. Then, within the Nineteen Sixties, he started making home windows for NASA spacecraft, together with the House Shuttle. Quick ahead to 2006 and we come to the fateful assembly between Apple and Corning.
Plastic screens had been the norm again then, however Apple cares an excessive amount of about aesthetics to let a tool get scratched. Greater than that, the iPhone was a touchscreen telephone, the display screen was the whole lot and it needed to be protected.
This was additionally true for different smartphones as they transitioned from keyboards and keypads to touchscreens. The primary iPhones used Gorilla Glass, as did the T-Cell G1, the very first Android telephone.

Contact telephones operating nearly each working system on earth have additionally adopted Corning’s glass. From the small Samsung Corby to the mighty i8910 Omnia HD. From the elegant LG KM900 Enviornment to the distinctive LG BL40 New Chocolate.
It was additionally on the Nokia X6 (now that the Finns had been transferring away from resistive contact), in addition to the Motorola Droid/Milestsone, the rugged Sonim XP3.20 Quest and even the LG GD910 watch telephone (we’ll discuss wearables later ). And people are only a few of the telephones from 2009.

In 2010, about 20% of cell telephones had been geared up with Gorilla Glass, or some 200 million units. In 2012, the sequel was introduced – sheets of Gorilla Glass 2 might be 20% thinner whereas remaining simply as sturdy.
GG2 was utilized by the likes of the Galaxy S III and the camera-turned-Galaxy Digicam GC100 telephone. Samsung has additionally used it on its Home windows Cellphone handset, the Ativ S, as has HTC on the creatively named Home windows Cellphone 8X.

By now Nokia had grow to be a fan of glass and it featured on the Lumia 920. Different influential telephones to make use of GG2 embrace the Oppo Discover 5 and LG Optimus G. Glass was even appropriate for 3D screens as seen. sees on the Optimus 3D Max. .

Gorilla Glass 3 arrived in 2013, a very new formulation. It was extra scratch resistant and the scratches it acquired had been much less noticeable due to one thing Corning referred to as “Native Harm Resistance”.
To exhibit this at MWC, Corning dropped a 135g metal ball onto a bit of regular and GG3 glass. The conventional glass cracked, so it was changed with aluminum foil. Dropping the ball once more left a dent within the aluminum, however Gorilla Glass 3 survived unscathed.
Sequels for some acquainted faces used GG3. Samsung’s Galaxy S4, Note3 and S4 zoom, for instance. The inexpensive Moto G, its high-end sibling Moto X (each made by Google-owned Motorola) and the LG Nexus 5.

There was additionally the Nokia Lumia 1020 and the large Lumia 1320 with its 6″ display screen (keep in mind it was 16:9 again then, this factor was 85.9mm vast and 164.2mm tall excessive).

Gorilla Glass 3 was one of the profitable formulations for Corning and it’s nonetheless used to today, listed here are some fashionable units. The Pixel 6a makes use of it for its show. The Asus ROG Cellphone 6 Professional makes use of it for its again. Apparently, the Motorola Edge 30 Professional makes use of GG3 for the entrance and GG5 for the rear. It’s nonetheless utilized by a rugged Sonim telephone and the Ulefone Energy Armor 14 Professional.

We have not talked about Apple shortly, what occurred? With the iPhone 5 in 2012, the corporate stopped utilizing the “Gorilla Glass” model identify and began calling it “ion-strengthened glass.” It was nonetheless a Corning product.
Cupertino really tried to get away from the glass round this level. He was working with GT Superior, an organization that made sapphire crystal shows for the Apple Watch. These had been additionally used to guard the Contact ID digital camera and fingerprint readers. However Apple needed greater sheets, which might cowl the display screen of iPhones. Sadly, the GT Superior went bankrupt making an attempt to develop the expertise to make it potential. Sapphire crystal has been used on some telephones, however none have the gross sales quantity of iPhones. It is largely a watch factor.
It is a good transition to Gorilla Glass SR+, a 2016 glass designed particularly for wearables. It supplied higher harm resistance and decreased display screen glare in comparison with “various luxurious cowl supplies”.
Then in 2018 got here Gorilla Glass DX and DX+, enhanced glasses for wearables. In line with Corning, it decreased glare by 75%, which improved display screen distinction by 50%. This was important for smartwatches, which solely had tiny batteries to energy their screens. The distinction between the DX and the DX+ was that the plus mannequin was tougher.
A couple of years later, Corning reintroduced Gorilla Glass DX and DX+ as safety for digital camera lenses. Scratch resistance and improved optical efficiency are simply as essential for cameras as they’re for watches. DX and DX+ let in 98% of sunshine whereas lowering glare (which may trigger reflections in photographs).
Corning’s newest formulations are Gorilla Glass Victus and Victus+ (it stopped with the numbered variations after 6). Based mostly on official checks, a smartphone with Victus glass on the entrance can survive a 2m (6.5ft) drop onto concrete and nonetheless have a useful display screen. It additionally boasted of superior scratch resistance in comparison with earlier generations.
Victus and Victus+ are actually the norm for flagships – the Samsung Galaxy S22 Extremely, Asus Zenfone 9, Google Pixel 6 Professional, Xiaomi 12S Extremely, Sony Xperia 1 IV, Galaxy Xcover 6 Professional, OnePlus 10 Professional, Oppo Discover X5 Professional and plenty of others others.

Corning additionally made Gorilla Glass for tablets and even laptops. The corporate has a protracted historical past of creating glass for bigger screens like TVs (although it isn’t marketed as “Gorilla Glass”).
Corning’s subsequent problem is foldable telephones – some use “ultra-thin glass” (UTG), which is one-third the thickness of a human hair. It is so skinny it may possibly bend, not like what glass usually does. However making it sturdy sufficient for a whole lot of day by day folding and unfolding cycles is not any small feat. Nonetheless, it is an essential subject to deal with as foldables are seen by some as the way forward for smartphones.
In 2020, Corning’s Gorilla Glass was featured on 8 billion units created by greater than 45 OEMs. It was a smash hit, contemplating the unique GG was unexpectedly assembled, developed in simply 4 months. It has gone by many iterations and enhancements and the rationale it was wanted within the first place has not gone away.
