Germany’s Schott has won in its competition against US’ Corning in supplying ultra-thin glasses (UTG) used in Samsung’s new foldable phones, TheElec has learned.

Schott is supplying all of the UTG mother glasses used by Samsung for its Galaxy Z Fold 3, as well as majority of the glasses used for Galaxy Z Flip 3, sources said.

Corning is supplying for only some of the volumes used in the Flip 3.

Samsung is using UTG mother glasses that are 30 micrometers thick for the two new foldable phones, which is the same spec as their predecessors.

Last year, Schott was the sole supplier of the mother glasses used for the cover glasses on the Galaxy Z Flip and Galaxy Z Fold 2.

Corning’s is being used less as it its offering its mother glasses at 50 micrometers thickness. This means they require an etching process to cut them down to 30 micrometers and processing of their surface afterwards, which increases cost.

Samsung was considering increasing the thickness of its UTG covers on its foldable panels to protect them from breaking and touch points of the S Pen.

This means Corning could later supply more glasses to the South Korean tech giant for future models.

Samsung Display has already developed a 60 micrometer thick UTG with a glass processing company.

It is also reviewing making the part of the glass that is folded thinner than the rest of the glass.

However, the firm will need to overcome the change in curvature caused by using thicker glasses.

Samsung has put in a spring in the S Pen that will accompany the Z Fold 3. The phone also has two digitizes, one for each side, with the middle placing reach the pen’s touch using software.
