Kyocera tests sapphire against resistant glass on video, things look promising
A leaked testing video by Kyocera shows the Japanese electronics maker is deep into the development of sapphire crystal-covered smartphone displays. The company is known for its rugged smartphones, thus the technology for durable displays, which is being researched by Apple as well, could be the next milestone in its product evolution.

The video in question shows Kyocera testing sapphire crystal display coverings sized for smartphone screens against traditional resistant glass. As expected, sapphire pretty much obliterates the traditional panels in shock-testing, emerging unscathed from a round of heavy scratching followed by an impact test. Sapphire is known as the second hardest material in the world after diamond, it's extremely hard to scratch, and is rated as three times stronger than Gorilla Glass. It could pave the way for near-indestructible smartphone displays in the near future, which sounds like an exciting proposition.

At this point, it isn't clear whether Kyocera plans to become a sapphire manufacturer, or is sourcing sapphire coverings for its own smartphones.

Knowing apple if their not going make money from broken screen replacement anymore then I guess something else is easily gonna get spoilt on the new iPhone. On the iPhone 5 and 5s people buy more lightening cable. It easily gets spoilt and you find yourself buying charging cables over and over. Greedy as company, throughout my entire life of using Samsung phones I have never found myself buying a charging cable. It last throughout the phones lifespan.

They are comparing that with their own resistant glass. They should test it out against a proper resistant glass like gorilla glass...

Apple started the "Gorilla Glass on phones" trend. Do you really think they would replace it with something that costs them a lot more to make and use if their own internal testing had not shown sapphire to be superior?

1st- Marketing my could ad their device saying that they have a gemstone which lost just for diamonds(and moissanite) in hardness, a loooot of people would buy an iphone just to tell that to a friend... 2nd - Where have you read that "internal testing had not shown sapphire to be superior?"?

Last I heard, sapphire is about 100 times as energy intensive to manufacture as Gorilla Glass. I'll pass for now.
