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.
