SEOUL — Apple has approved Samsung Display to begin mass production of foldable OLED modules for its first foldable iPhone, according to The Elec, the South Korean trade publication, which cited industry sources. The approval clears the last major hurdle before the panels ship, and Samsung Display has already brought part of its Vietnam factory’s back-end production lines into use for the task.
The first batch of roughly 3 million panels is scheduled for delivery this year, according to the report. The module mass-production certification is the formal gate that panel suppliers must pass before becoming official vendors: auditors check final assembly quality, product performance and the stability of mass production, and the stakes are high because a failure at this stage can delay an entire product line.
The yield requirement tells the story of how demanding the process is. Apple asked for a yield of at least 70% on the foldable modules, and Samsung Display passed with a yield above 80%, according to the sources. Foldable panels are among the most difficult components in consumer electronics: the flexible OLED must bend millions of times without cracking, and the hinge area concentrates stress that flat screens never experience.
The deal makes Samsung Display the exclusive supplier of OLED panels for Apple’s first foldable phone. The two companies have signed a three-year exclusivity agreement, under which Apple will not purchase foldable OLED panels from other suppliers, and this year’s shipments are expected to be about 3 million units. The back-end processing will be handled at Samsung Display’s Vietnam facility, part of a supply chain that spans the border between the two countries’ electronics industries.
The exclusivity is a significant win for Samsung Display, which has long supplied a large share of Apple’s iPhone screens but has competed with LG Display and BOE for orders. A three-year exclusive on the industry’s most anticipated new form factor gives Samsung Display a stable revenue line and a strong negotiating position for the panels that follow, analysts said. For Apple, the deal trades supplier diversity for a guarantee of quality at a moment when the foldable launch can afford no defects.
Apple is entering the foldable market late. Samsung Electronics has sold foldable phones since 2019, and its Galaxy Z series has gone through five generations of refinement; Huawei, Oppo and Google have all shipped foldables in the years since. The late entry is a deliberate choice, people familiar with Apple’s product planning have said, reflecting the company’s preference for entering categories only when the technology meets its standards. The certification process with Samsung Display, with its 70% yield floor, is consistent with that approach.
The supply arrangement carries a strategic wrinkle. Samsung Display is part of the same corporate family as Samsung Electronics, Apple’s most important rival in the phone market, and the two companies have a long history of competing while cooperating: Samsung has supplied Apple with screens, memory and batteries for years even as their phone businesses battle for the same customers. The foldable deal extends that pattern into the next product cycle, and neither company appears to have blinked at the arrangement.
The financial stakes are substantial. A foldable iPhone is expected to carry a price well above the standard models, and the display is the single most expensive component in the device. Analysts estimate the foldable panel alone could cost several times as much as a conventional iPhone screen, which would make the three-year contract one of the most valuable display agreements in the industry’s history if the product sells in the volumes Apple expects.
The market reaction in Korea was muted, in part because the news arrived amid the worst week for Korean stocks in years. But supply chain analysts read the certification as a signal that the foldable iPhone is on schedule, and that Apple’s suppliers have passed the hardest tests in the qualification process. The 3 million units planned for this year represent a cautious start, the analysts noted, consistent with a product line that will be refined in subsequent generations.
The bigger question is what comes after the first foldable. Apple’s roadmap is reported to include multiple foldable devices, and the three-year exclusivity with Samsung Display suggests the first generation will be followed by others on a predictable cadence. For the display industry, that would mean years of capacity devoted to foldable panels, and a race among suppliers to qualify for the second source position that Apple is likely to open once volumes justify it.
For now, the certification is the fact that matters. Samsung Display has passed the gate, its Vietnam lines are running, and the first foldable iPhones are scheduled to ship before the end of the year. The longest-running rumor in the phone industry is about to become a product, and the company that will supply its most important part is the same company that has supplied Apple’s screens for decades.
