Samsung Galaxy Z Fold 7’s display is rated to withstand 500,000 folds

Samsung said the display it used for the Galaxy Z Fold 7 can be folded over twice as many times as the display used for the previous iterations of the model. The foldable OLED panel “remained fully functional” after certification company Bureau Veritas put it through a durability test, wherein it was folded 500,000 times over 13 days. That means if a user folds their phone roughly 100 times a day, the display could last for over 10 years. In its announcement, Samsung said that “durability is no longer a limiting factor in the lifespan of foldable smartphones.”

The company took cues from bulletproof glass to create a shock-proof design for the new foldable OLED panel. It increased the thickness of the display’s outermost glass by 50 percent and applied high-elastic adhesive to every layer of the panel so that it can better absorb external impact. The new display can also distribute shock more evenly across its surface, and Samsung used titanium plate as support for the whole structure to make it stronger than before. In addition, by using more advanced materials and redesigning the panel layer, the company was able to achieve a thinner profile so that the device looks and feels like any regular handset now.

Previous versions of the Galaxy Z Fold, from the first through the sixth, were only rated for 200,000 folds. And when CNET tested the first Z Fold itself by using a machine that opened and folded it for hours, it only lasted 119,380 folds despite supposedly being able to withstand 200,000. If the Galaxy Z Fold 7 can get anywhere near the 500,000 folds it can supposedly handle, most users don’t have to worry about their screens snapping in two before they change phones.
