Tech InDepth: How does Gorilla Glass hold your smartphone show protected?
Corning’s Gorilla Glass has been round for years now, going by means of a number of variations to guard a few of the hottest smartphones at present. The most recent within the sequence is Gorilla Glass Victus 2 which launched earlier this week. Whereas the know-how is synonymous with show safety, simply how a lot will we really find out about Gorilla Glass, its numerous variations and the way it really works? In at present’s version of Tech InDepth, we take a look at how Gorilla Glass really works and perceive what goes into making Gorilla Glass Victus 2 so robust.
What’s Gorilla Glass?
The display is an important side of most fashionable smartphones, performing as the first enter and output element for many duties. It’s crucial that it stays clear, practical and damage-free for long-term utilization. However how do you make glass, some of the fragile supplies round us, robust? That is precisely the place Corning and its Gorilla Glass is available in.
The Gorilla Glass sequence contains a layer of toughened glass that sits above the digitiser on a smartphone display. It protects the parts beneath from injury primarily from drops and scratches. By staying freed from cracks and scratches, the glass layer additionally ensures good visibility for the person and a clean contact expertise whereas utilizing the telephone.
How is it made?
Earlier than we get into Gorilla Glass, we have to perceive the idea of toughened glass. Toughened Glass is a sort of glass that has been part of most telephones and different handheld units for years now. Not like regular glass which may crack simply, toughened glass makes use of chemical compounds to make the bonds between its stable molecules even stronger, making the fabric far more resilient to wreck.
Utilizing a course of known as Ion Trade, glass with Sodium ions embedded in it’s dipped into a shower of liquid potassium salt. The Potassium ions displace the Sodium ions when the tub is heated to temperatures of round 400 levels Celsius. Nevertheless, the newly embedded Potassium ions are additionally bigger than the Sodium ions.
This offers the molecular construction of the fabric a type of inner rigidity, with the bigger potassium ions now pushing in opposition to one another within the restricted area, making the molecular bonding of the construction a lot more durable than earlier than.
From there, Corning has made its Gorilla Glass harder over a number of variations through the years. Whereas the ion trade fundamentals stay the identical, what modifications is how deep the method is carried out on the glass. With Gorilla Glass Victus, Corning started giving the glass sheets a second ion bathtub, displacing extra Sodium ions with Potassium ions, strengthening the glass extra. Moreover, Corning additionally makes use of stronger glass in comparison with the early Gorilla Glass years. Nevertheless, what tech goes into this glass is a well-kept commerce secret that’s key to Corning’s enterprise.
Gorilla Glass Victus 2: What’s new?
Victus 2 is an enchancment over the unique Gorilla Glass Victus commonplace which was introduced again in 2020. The principle enchancment with Victus 2 is the safety the glass presents in opposition to drops.
Corning has used new, improved strategies to make the glass stronger, and has additionally up to date their testing parameters, now utilizing rougher surfaces to mimic real-life drop surfaces like concrete or asphalt, and in addition utilizing heavier pucks to simulate at present’s heavier telephones.
Is Gorilla Glass the one toughened glass on the market?
Properly, no. Whereas Gorilla Glass is without doubt one of the main protecting glass producers within the enterprise, there are different names you will have come throughout like Dragontail Glass or the extra well-liked, Sapphire Glass which is used on many high-end wearables at present just like the flagship Apple Watch sequence variants.
Sapphire Glass makes use of a unique chemical course of to make triangular-placed aluminium oxide molecules, that are stronger in opposition to scratches. However it is usually far more costly to provide in comparison with Gorilla Glass. As per experiences, Sapphire is about ten occasions costlier to provide in comparison with Gorilla Glass.
