No one is very happy with the screens of the foldable smartphones that have recently been released: they all use plastic. Of course, glass screens and protective layers such as the Gorilla Glass cannot be folded, so smartphone manufacturers are always looking into other materials.
However, things might soon change (and they have to, if the foldable phone wants to secure its place in the industry): according to ET News, Samsung is planning to use ultra-thin glass as cover for the screen of its future foldable smartphone.
This upcoming device will not be a successor to the Galaxy Fold and will have a clamshell design instead but even this piece of information is still in the air: allegedly, the company is not yet deadset on a particular design.
According to ET News, Samsung is already hard at work to manufacture this foldable display and is even working side by side with a firm called Dowoo Insys, which is responsible for producing the ultra-thin glass.
Of course, it comes along with a high-production cost and we can expect the smartphones who will feature this type of ultra-thin glass to come with a hefty price tag.
“Although Samsung had looked into many different UTG manufacturers, Dowoo Insys clearly has the best technical skills when it comes to UTG,” an industry manufacturer told the publication. “Its technical skills are four to five years ahead of its competitors.”
How is this ultra-thin glass achieved though?
Well, the publication says that the glass goes through an extra tampering process that improves its strength. Other than that, nothing much is known about it, as it is considered a trade secret.
