Apple’s first foldable, widely expected to launch as the iPhone Ultra in September, depends entirely on Samsung Display being able to manufacture foldable OLED panels at scale and according to a new report, that hurdle has just been cleared. Samsung Display has reportedly received approval to begin production after achieving over 80% manufacturing yield, a critical threshold that determines whether mass production is commercially viable.
This follows an earlier April report confirming Apple selected Samsung Display as the exclusive supplier for the device’s foldable OLED panels, no surprise given Samsung’s years of foldable display experience powering its own Galaxy Z Fold lineup. What’s new is the manufacturing reality behind that decision. Samsung Display’s facility in Vietnam has already begun operations, and Apple has reportedly requested an initial batch of 3 million OLED panels for this year, a number that suggests genuine confidence in a September timeline rather than a tentative trial run.
The display technology itself has apparently changed since earlier leaks. Initial reports suggested Apple would use Samsung’s M14 display stack, but the latest information points to the newer M16 luminescent material instead. The M16 stack reportedly delivers higher brightness, improved color reproduction, better power efficiency, and a longer operational lifespan compared to its predecessor, meaningful upgrades for a foldable display that needs to withstand hundreds of thousands of fold cycles over its lifetime. The panels also reportedly incorporate Color Filter on Encapsulation (CoE) technology, a manufacturing approach that typically improves color accuracy while reducing panel thickness exactly the kind of refinement a foldable needs given how much internal space the folding mechanism itself consumes.
For context, achieving 80%+ yield on foldable OLED production is genuinely difficult. Samsung itself struggled with yield rates in the early generations of its own Galaxy Fold lineup before stabilizing.
An exclusive supplier, a working factory, an upgraded display stack, and millions of panels already on order this is no longer rumor-stage speculation. The iPhone Ultra’s foldable screen is being built right now.
