I hear Gorilla Glass 3 is coming out.

[glen]

What is the scoop?

 

[zerogear]

Rumor is that next iPad/iPhone will be first to have it. Who knows?

Looks interesting.

But can it consistently survive a 4ft drop test on a concrete road? I never shoot metal marbles at my phone...

 

[Geekbabe]

I was impressed with the gorilla glass peeps at ces.. I'm eager to see the new glass in devices

 

[gmaster456]

I don't give a damn how far it can bend, I wanna know if it can survive a 4ft fall onto cement and not shatter.

please stop before you start. i am so sick of complaints about gorilla glass. it has been a godsend to cellphones and tablets. do you have any idea what it was like before the stuff came out?

gorilla glass is by far the best glass you can get. if you dont like it, make something better.

I don't see where he stated it was bad...

if you dropped your head 4ft onto concrete you wouldnt survive either.

 

[wirednuts]

he made an incredibly ignorant and dismissive comment that clearly shows his lack of understanding of the engineering and chemistry involved to make the best optical protection out there.

If you got stabbed you would bleed.

If you got stabbed you would bleed.

if you sat down you would be lower in altitude.

Butthurt much? I have nothing against the engineering that was made into Gorilla glass, better than nothing/before, but from a practical perspective there is plenty of need for improvement. Pretty sure they'll get there at some point.

Dude... He made a valid point. He's saying that these laboratory benchmarks are kind of irrelevant. Wouldn't you have preferred to see them intentionally drop phones on the ground at CES, as opposed to rolling a ball through a tube?

Also, did anyone else see a problem with this logic?
1. Ball rolls down a 10 degree incline, hits the glass.
2. Later, the lady raises it to a 30 degree impact and says it's 3 times the energy. Looks like Corning no good at the maths.

Actually, no.
Too many random variables in a drop to the ground.
Metal ball in a tube is repeatable and give a great relative sense of strength when comparing different glass.

I think there is a great deal of misunderstanding about what gorilla glass was designed to do. Its a tough scratch resistant surface that dos not hinder the optical output of the screen. It was never designed to be thrown at the floor or deflect bullets.

Remember how smartphone screens used to look after a year of use before gorilla glass for sure this is a great product

They need to have some sort of edge impact test. Thats the area that needs improving the most.

This as well.

No there isn't. You take a fixed piece of glass in a cage at a 30 degree angle.

You drop a flat weight on the edge from a premeasured distance. Voila, edge impact tests done easily and reproducible.

Basically all they have to do is make a cheap and tiny version of an impact test machine.
Can easily cook one up in about 30 minutes

Flat impact tests are usually not a good indicator for normal usage because phones rarely drop flat on the screen. They always tend to be at angle so the edge almost always takes most of the energy. All this chemical treatment to make it tougher from one direction and harder to resist scratches, REALLY screws with its edge impact cracking resistance. My GS3 got cracked when it fell down literally 2.5 feet onto pavement when I dropped with while taking it out of my pocket. The bezel is too thin to absorb the energy before it gets to the glass.


Straight on impact performance has already been good for a few years now. Now work on edge performance, the most common type of impact.

Also, 10 degrees vs 30 degrees is not 3 times more energy.

Gorilla glass does not shatter because they do not know how to test it but because reducing glasses brittleness is counter to what gorilla glass was aiming to achieve. To reduce scratches you need a very hard surface, the downside of this is that increased hardness also increases brittleness.

There are other types of glass which are far more robust when dropped, such as those made from soda-lime-silica. But the scratch resistant properties are far reduced.

Having both properties may currently be possible but I'm guessing it will not be at a price that consumers will accept. A better solution may be to do away with edge-to-edge glass screens. But like many, I love the look/feel of modern phones.

basically all of this
also the people at CES are not often engineers (in reference to the bad at maths comment)

Scratch resistance only affects very minor aspects of the screen, scratches are merely cosmetic.

Cracks can actually heavily affect the operation of the phone and heavily hinder enjoyment. Most consumers are perfectly happy putting scratch protectors on their screens. Crack resistance is much much more important, because unless you put a heavy duty case on, cracks are much more likely to happen.

Sure would, in some cases with a slight concussion. I have seen it in my teens hanging with insanely wild and crazy friends!

It goes a little deeper than that. Gorilla glass is "tough" because it is under compression at an atomic level. All glass does very well under compression but poorly under tension or shear forces. It's fallacious to say "it's harder so it's harder to scratch but shatters more easily".

I think you miss the 2nd point of market economies. Complaining is a signal to makers of profit potential.
