Samsung Galaxy Z Fold 7 Display Can Be Folded 500,000 Times, According to Testing
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.

Samsung shares jump on news of $16.5 bln Tesla chips deal
STORY: Samsung Electronics shares jumped Monday (July 28) on news of a big deal to make chips for Tesla. Elon Musk says his EV firm has signed a $16.5 billion contract for the supply of semiconductors. That should be a big boost for Samsung's loss-making contract chip-making business. Shares in the firm were up around 6% by early afternoon following the news. Musk said a new Samsung facility in the U.S. would be dedicated to production of the chips. That could refer to a planned plant in Taylor, Texas, which has faced delays amid the South Korean firm's struggles to win and retain big customers. Musk said the plant was conveniently located near his house, and he would personally inspect it to help accelerate progress. It's all very timely for Samsung, which has dropped behind competitors in the race to supply AI chips. Local rival SK Hynix and Taiwan giant TSMC are both seen to have streaked ahead. That has weighed heavily on Samsung's profits and share price.

Samsung to Make Tesla AI Chips in Multiyear Texas Deal
(Bloomberg) -- Samsung Electronics Co. will produce AI semiconductors for Tesla Inc. in a new $16.5 billion pact that marks a win for its underperforming foundry division. The High Costs of Trump's 'Big Beautiful' New Car Loan Deduction Can This Bridge Ease the Troubled US-Canadian Relationship? Trump Administration Sues NYC Over Sanctuary City Policy Budapest's Most Historic Site Gets a Controversial Rebuild South Korea's largest company announced on Monday that it secured the 22.8 trillion won chipmaking agreement, which will run through the end of 2033. The plan is for an upcoming plant in Taylor, Texas, to produce Tesla's next-generation AI6 chip, Tesla chief Elon Musk said on X, confirming a Bloomberg News report. Samsung's Seoul-traded shares rose 6.8%, to their highest since September, while its suppliers like Soulbrain Co. jumped as much as 16%. A Samsung spokesperson declined to comment, citing confidentiality terms in its contract. 'The strategic importance of this is hard to overstate,' Musk, 54, wrote on X. He described the value of the deal announced by Samsung as 'just the bare minimum. Actual output is likely to be several times higher.' The Tesla chief executive officer and X owner will walk the chip fabrication line himself and has been authorized by Samsung to assist in optimizing production, he said. The AI6 component will form the foundation of Tesla's self-driving hardware suite for cars in coming years. Samsung produces the current AI4 system, according to Musk. The contract win, the first after Executive Chairman Jay Y. Lee was cleared of all outstanding legal charges, comes as Samsung has been steadily losing ground in chip manufacturing. The company, which makes its own memory chips and also fabricates semiconductors on behalf of clients, has had difficulty bringing in enough orders to fully utilize its foundry capacity. It has postponed completion of construction and operational ramp-up of its new Texas fab to 2026. 'Their foundry business has been loss-making and struggling with under-utilization, so this will help a lot,' said Vey-Sern Ling, managing director at Union Bancaire Privee in Singapore. 'Tesla's business may also help them to attract other customers.' That's in contrast to leading chipmaker Taiwan Semiconductor Manufacturing Co., which still cannot meet all demand. TSMC held a dominant share of 67.6% of the global foundry market in the first quarter this year, according to Taipei-based TrendForce. Samsung's share slipped to 7.7% from 8.1% in the previous quarter. Samsung and TSMC are both on pace to deliver the next generation of semiconductor advancement — moving to 2-nanometer fabrication — and the new deal is seen as a signal of confidence for the company's upcoming fabrication technology. While the contract may represent a small share of foundry revenue annually, it holds greater value as a catalyst for technological refinement and innovation over the long run, according to Ryu Young-ho, an analyst at NH Investment & Securities Co. It also helps burnish Samsung's reputation as the strongest TSMC alternative at a time when Intel Corp. is struggling to win over investors skeptical about its long-term strategy and road map. What Bloomberg Intelligence Says Samsung Electronics' new contract to supply semiconductors implies a recovery in its foundry business' 2-nanometer generation chip production. The $16.5 billion contract spans 2025-33 and could boost Samsung's foundry sales by 10% annually, we calculate. — Masahiro Wakasugi and Takumi Okano Click here for the full research --With assistance from Seyoon Kim, Linda Lew, Abhishek Vishnoi and Vlad Savov.
