“While sapphire is a very hard material and very scratch proof, there is one major problem with it that actually makes it questionable for use as a smartphone screen,” Tim Bajarin writes for Tech.pinions.
“While the surface is very scratch proof, it is much more breakable than Corning’s Gorilla Glass and even some soda lime glass that has special composites to make it tougher,” Bajarin writes. “Even worse, if there is even the tiniest flaw in a sapphire screen, it becomes even more fragile when it comes to being dropped or accidentally hit by any solid surface or object.”
“At a special event in Palo Alto last week, Corning announced its newest version of Gorilla Glass 5, which is by far the thinnest as well as strongest glass screen they have ever made,” Bajarin writes. “Gorilla Glass 5 is already shipping to vendors and will be in some smartphones by this fall. Corning’s commitment to creating even thinner glass with harder surfaces is significant. I believe Gorilla Glass 5 makes it unlikely a sapphire smartphone screen of any type will ever gain traction.”

MacDailyNews Take: Let’s all pause for a moment of silence at the Boule Graveyard.
And thank you, Steve Jobs, for Gorilla Glass. The existence of Gorilla Glass as a consumer product came about as a result of the original iPhone. During the development of the iPhone, Apple CEO Steve Jobs flew to Corning, New York to meet with Corning CEO Wendell Weeks.
Jobs said he wanted as much gorilla glass as Corning could make within six months. “We don’t have the capacity,” Weeks replied. “None of our plants make the glass now.”
“Don’t be afraid,” Jobs replied. This stunned Weeks, who was good-humored and confident but not used to Jobs’ reality distortion field. He tried to explain that a false sense of confidence would not overcome engineering challenges, but that was a premise that Jobs had repeatedly shown he didn’t accept. He stared at Weeks unblinking. “Yes, you can do it,” he said. “Get your mind around it. You can do it.” As Weeks retold this story, he shook his head in astonishment. “We did it in under six months,” he said. – Steve Jobs by Walter Isaacson
