Corning introduces Gorilla Glass SR+ for wearables

The future of wearable technology is vast, and companies know this. That’s why we are seeing more and more wearable-specific components: Qualcomm introduced its very first wearable chipset earlier this year, and now Corning is following suit. The all new Gorilla Glass SR+ is designed with smartwatches in mind, focusing on scratch-resistance and optical transmission.

Corning first announced “Project Phire” back in 2015: it was an attempt to create a material for wearable technology that would combine the best features of its very own Gorilla Glass and sapphire. And Gorilla Glass SR+ is the result of this research. It boasts the durability of Gorilla Glass and (almost) the scratch-resistance of sapphire all the while being extremely thin and transparent.

Combining sapphire and technology isn’t a novel concept at all. Back in 2014, we saw the launch of the Kyocera Brigadier, rocking a 4.5-inch Sapphire Shield screen. Apple’s iPhones have had a sapphire home button for quite some time now. And the high-end Apple Watch comes with sapphire protection over its screen.

Sapphire is, in fact, remarkably hard, which makes it almost as scratch-resistant as diamond. Why isn’t everyone using sapphire then, especially companies like Samsung and Apple? Well, there are a few factors that suggest sapphire alone cannot be the answer.

First is availability (or the lack thereof): Apple was rumored to bring sapphire protection to the iPhone 6, but that did not happen, and it’s most likely to have been due to production issues. No company can deliver large enough quantities of the material to meet the demands of companies like Apple and Samsung. But there is a more practical reason too: sapphire’s optical transmission is poor. Its sheer thickness and high reflective index mean things aren’t as bright and visible as they can be.

That’s precisely why Corning was so set on finding a balance – something that would be thin, clear, durable, and scratch-resistant all at the same time. According to Corning’s figures, the all new Gorilla Glass SR+ is much more scratch-resistant than GG4 or GG5. In fact, it’s almost as scratch-resistant as sapphire itself. However, it’s at the same time almost as efficient in optical transmission as GG4 and GG5. Its thinness – which is comparable to GG4 and GG5 – plays a big role in it.

According to Corning’s figures, the all new Gorilla Glass SR+ is much more scratch-resistant than GG4 or GG5. In fact, it’s almost as scratch-resistant as sapphire itself.

It’s unclear whether Gorilla Glass SR+ actually has sapphire in it, but one thing is for sure: smartwatches are about to become stronger with even more scratch-resistance. Gorilla Glass SR+ is set to hit the market later this year, which means we could see it in the upcoming Gear S3 or Apple Watch 2.

Corning Unveils Corning® Gorilla® Glass SR+, Designed to Overcome the Unique Challenges of Wearable Devices

CORNING, N.Y. | Corning Incorporated | August 30, 2016

Breakthrough glass composite delivers an unparalleled combination of toughness, scratch resistance and optical clarity for today’s wearable devices

Corning Incorporated (NYSE: GLW) today announced its groundbreaking innovation – Corning® Gorilla® Glass SR+. Specifically designed for wearable devices, this new glass composite significantly reduces visible scratches while delivering the toughness, optical clarity and touch sensitivity that make Gorilla Glass famous.

With rigorous daily activity, consumers put their wearable devices to the test, leaving them exposed to damage. To overcome the challenges facing the screens on these devices, Corning scientists developed a new glass composite engineered to better endure the bumps, knocks and scrapes wearables encounter while maintaining the optical clarity and touch sensitivity required for on-the-go connectivity.

In a league of its own

In lab tests, Corning Gorilla Glass SR+ demonstrated superior scratch resistance approaching that of alternative luxury cover materials, while delivering up to 70 percent better damage resistance against impacts and 25 percent better surface reflection than those alternative materials. Such step improvements in optical performance enable longer battery life and improved outdoor readability.

“In early 2015, Corning launched Project Phire with the goal of engineering glass-based solutions with the scratch resistance approaching luxury cover materials, combined with the superior damage resistance of Gorilla Glass,” said Scott Forester, director, innovation products, Corning Gorilla Glass. “Corning Gorilla Glass SR+ delivers a superior combination of properties that is not available in any other material today – it is in a class of its own.”

Leveraging its strengths in glass science and fusion manufacturing, Corning leads the cover glass industry it created nearly 10 years ago. Corning Gorilla Glass has been used on more than 4.5 billion devices worldwide, including more than 1,800 product models across 40 major brands. With the introduction of Corning Gorilla Glass SR+, the one company that has been innovating with glass for 165 years offers manufacturers of wearable devices a clear alternative to luxury cover materials.

Corning Gorilla Glass SR+ is commercially available and is expected to be on product models from leading global brands later this year.
