Samsung's latest foldable OLED sets new benchmark, proves durable in 500,000-fold test
South Korean smartphone giant Samsung seems to be leading in the foldable OLED display market. The company, on Wednesday, July 23, announced that its latest foldable OLED panel stays intact even after a 500,000-fold durability test. The OLED panel was tested by Bureau Veritas, a certification company. Samsung Displays raised its internal durability testing standard from 200,000 to 500,000 folds, which is two times more than their previous benchmark. The OLED panel used for this testing is built into the recently launched Samsung Galaxy Z Fold 7. This exceptional durability is made possible by the Samsung display's newly developed architecture that is shock resistant and is inspired by the core principles of bulletproof glass, which increases the lifespan of foldable devices. This test was conducted by Bureau Veritas, where they mentioned that over the span of 13 days at 25°C, the panel remained fully functional even after 500,000 folds. The lifespan of foldable smartphones is no longer limited by durability. 500,000 folds mean that the device could last about 10 years for those who, on average, fold 100 times a day and over six years for those folding more than 200 times per day. The company has opted for a titanium plate to support the display. They also added a new flattening structure to disperse shock uniformly throughout the panel. The titanium plate is more protective and has a smaller form factor than other materials because it is lighter and thinner while yet offering excellent strength. 'As foldable OLED enters its seventh year of commercialisation, we've achieved another meaningful breakthrough in both durability and design. This new panel not only builds consumer confidence in foldable OLED durability but also underscores the technological advantage that makes Samsung Display distinguished in the industry,' said Hojung Lee, executive vice president and head of the Mobile Display Product Planning Team at Samsung Display. As mentioned above, the new OLED panel is inspired by bulletproof glass. And, to build one, an individual would require several layers of reinforced glass and plastic sheets. The flexibility of the outer layer of glass absorbs a large portion of the impact energy when a bullet hits the surface, preventing penetration. This design concept is adopted in the OLED panel by applying a new high-elastic glue to every layer within its OLED screen and thickening its outermost UTG (Ultra Thin Glass) by 50%. Samsung Display implemented this idea, providing more than four times the recovery performance over the prior material. The panel's capacity to withstand external impact is greatly increased by these improvements.

Samsung Galaxy Z Fold 7 Display Can Be Folded 500,000 Times, According to Testing
Fold, fold and fold again. It doesn't matter how many times you fold the Galaxy Z Fold 7 open and closed -- it's highly unlikely to give out on you. Samsung Display (SDC) announced Tuesday that its latest foldable OLED panel "remained fully functional after a 500,000-fold durability test," more than doubling its previous benchmark of 200,000 folds. The company says this screen is the one you can find on Samsung's Galaxy Z Fold 7 phone. Bureau Veritas, a French leader in testing, inspection, and certification, tested the screen with 500,000 folds over a 13-day period at a temperature of 25°C (77°F). For those of you trying to wrap your head around the math, half a million folds translates to the average user folding their phone 100 times a day for 10 years, or prolific users doing 200 folds a day for 6 years. Samsung Display -- a separate company from Samsung itself -- says the durability results prove that "durability is no longer a limiting factor in the lifespan of foldable smartphones." "As foldable OLED enters its seventh year of commercialization, we've achieved another meaningful breakthrough in both durability and design," Hojung Lee, EVP at Samsung Display, said in a press release. "This new panel... builds consumer confidence in foldable OLED durability." Bulletproof glass technology has helped Samsung Display develop its creaseless screens. SDC borrowed from the concept and increased the thickness of its Ultra Thin Glass (UTG) -- the outermost glass on the screen -- by 50%. SDC also added high-elastic adhesive to each screen layer, thereby enhancing fold recovery performance by four times the previous design. CNET reported last week that Apple has tapped Samsung Display to manufacture screens for Apple's first foldable iPhone, set to launch in summer 2026. With the era foldable phones upon us, these are the best ones in 2025.
