The display crease has been a sticking point on Samsung’s folding Galaxy phones for years, but the company recently showed off a new tech that seems to fix it. According to a new report, a key part of that is a second layer of ultra-thin glass.
At CES 2026 earlier this month, Samsung showed off a new foldable display tech that it called “Advanced Crease-less.” The new panel was quickly removed, but not before the world saw just how big of a difference it made in the display crease compared to the tech currently being used in the Galaxy Z Fold 7, and it sounds like there’s a chance this debuts as soon as the Galaxy Z Fold 8 (or maybe even in Apple’s foldable iPhone).
But how did Samsung pull it off?
One leak revealed that Samsung is “weakening” the backplate by introducing perforated holes that allow the backplate to flex and distribute the stress of the folding action across the entire display, rather than concentrating it at the center as the current design does.

Dealsite, a Korean publication, is adding on that explanation. Samsung will, apparently, indeed be using “a laser drilling process to the backplate” to “disperse stress,” but the new tech may also involve a secondary sheet of ultra-thin glass (UTG).
Samsung currently has ultra-thin glass underneath a plastic protective layer on devices such as the Galaxy Z Fold 7, with the display underneath the glass, and the backplate behind that. To further protect against “wrinkles” in the display, the company is apparently also looking to use a second layer of ultra-thin glass on top of the backplate.
It’s unclear if this second layer was a part of the panel Samsung showed off in Las Vegas earlier this month, but it certainly sounds like an interesting solution. The addition of ultra-thin glass on Samsung foldables made a difference in the uniformity of the display compared to the first generation, so it stands to reason that this new structure could bring further improvements.
