As leading device manufacturers unveil their latest models, many are making a shift to incorporate more advanced glass into their designs, and not just on the front as a protective cover glass. One place where more glass is appearing is on the back of new mobile consumer electronic devices. This trend is particularly exciting because glass offers benefits that other materials, like plastic and metal, just can’t offer.
"We are not only benefiting from adoption of our premium glasses, but also from more glass on each phone," said Wendell P. Weeks, chairman, chief executive officer and president of Corning. "Glass back penetration on smartphones doubled from 15% in 2017 to 30% in 2018 and we expect continued growth in 2019."
With glass on the back as well as the front, the newest smartphones are meeting aesthetic and design milestones, including more elegant form factors. But, they offer additional performance benefits. The superior physical and electromagnetic properties of glass make it particularly well-suited to enable new capabilities device makers are incorporating into their designs.
So what are the benefits of having an all-glass smartphone?
