A crease-free foldable display has been the defining unsolved problem of the smartphone industry for six years — and for the first time, there’s credible hardware evidence that Apple and Samsung may have cracked it. At CES 2026, Samsung Display showcased a foldable OLED panel described as having “no crease at all” compared to the Galaxy Z Fold 7, which still shows crease visibility at certain angles. That demo didn’t just raise eyebrows. It potentially unlocked Apple’s long-delayed entry into the foldable market.
TL;DR: Samsung Display’s CES 2026 demo showed a foldable panel with no visible crease, enabled by a laser-drilled metal plate from South Korean supplier Fine M-Tec. The same component is reportedly headed to both the Galaxy Z Fold 8 and the iPhone Fold, with Apple’s device targeting a mid-September 2026 launch alongside the iPhone 18 series.
Why the crease-free foldable display problem is so hard to solve
The crease in every foldable phone on the market isn’t a design oversight — it’s a physics problem. When a display folds repeatedly, the plastic polyimide substrate experiences differential stress across the bend, causing permanent deformation in multiple layers including encapsulation, touch sensors, and polarizers. The result is that ridge you can see and sometimes feel, no matter how many times manufacturers refine their hinges.
Samsung has iterated through six Galaxy Z Fold generations, introducing ultrathin glass (UTG) and progressively refined display stacks, yet the crease has persisted. Google’s Pixel Fold has it. The Motorola Razr has it. Every foldable phone shipping today has it. One YouTuber described a crease-free design as “the Shangri-La that every phone manufacturer has been chasing, but nobody has solved”. That framing is accurate — until now, it remained aspirational.
The laser-drilled metal plate that could finally fix it
The key component enabling a crease-free foldable display is a laser-drilled metal plate developed by Fine M-Tec, a South Korean supplier. The plate disperses bending stress across the fold rather than concentrating it, which is what causes the permanent deformation in conventional designs. It’s a materials engineering solution to what was previously treated as a geometry problem.
Critically, this isn’t a prototype component exclusive to a concept device. The same laser-drilled plate is reportedly being used in both the Galaxy Z Fold 8 and the iPhone Fold. That means the technology is entering mass production in parallel across two of the most anticipated foldable devices of 2026. Samsung Display’s CES demo showed the panel delivering “seamless text across the fold” from any viewing angle — a claim that, if it holds up in production units, would represent a genuine step change from anything currently available.
Is the crease-free foldable display actually why people avoid foldables?
Not everyone is convinced the crease is the real barrier to foldable adoption. One reviewer who has used Samsung Fold devices since 2019 put it bluntly: “I don’t care about the crease… normal people aren’t buying these things. And the crease is not why”. That’s a fair challenge. Foldables remain a niche category, and the reasons — high prices, software immaturity, device thickness, durability concerns — extend well beyond display aesthetics.
But Apple’s calculus is different. Apple has famously refused to enter the foldable market until the crease problem is solved. That’s not just a design preference — it’s a brand protection decision. Apple doesn’t launch products that look unfinished. If the iPhone Fold ships with a visible crease, it becomes a punchline. If it ships without one, it becomes the benchmark every Android foldable gets measured against. The stakes are asymmetric in a way they simply aren’t for Samsung, which has been willing to ship iterative improvements across multiple generations.
What the iPhone Fold is expected to look like
Based on current leaks, the iPhone Fold is shaping up as a distinct design philosophy compared to Samsung’s approach. The inner screen is expected to measure 7.8 inches with a 4:3 aspect ratio when open — squatter and wider than Samsung’s taller, narrower Fold format. That proportioning aligns more closely with an iPad than a stretched Android phone, which suggests Apple is building the device around iPad-style productivity rather than trying to replicate a conventional phone experience on a bigger canvas.
iOS 27 is expected to bring side-by-side multitasking features that take advantage of the larger unfolded screen. On the production timeline, display panels from Samsung are slated for mass production in May 2026, with full device mass production following in July 2026. A mid-September 2026 launch alongside the iPhone 18 series remains the target, though no pricing has been confirmed.
How does the iPhone Fold compare to the Galaxy Z Fold 8?
The Galaxy Z Fold 8 and iPhone Fold share the same Fine M-Tec laser-drilled plate, meaning both devices should theoretically benefit from the same crease-reduction technology. The Galaxy Z Fold 8 is expected to launch in summer 2026, giving Samsung a window of a few months before Apple’s September target. That head start matters — Samsung will get to define what “crease-free” means in practice, and Apple will either validate or surpass that benchmark when the iPhone Fold arrives.
Will the iPhone Fold actually launch without any crease?
The CES 2026 demo from Samsung Display showed a panel with no visible crease, but demo conditions and production reality don’t always match. Long-term durability of the laser-drilled plate under real-world folding cycles remains unproven. The display looked compelling at a trade show booth — whether it holds up after 100,000 folds in daily use is a question that only shipping hardware can answer.
When is the iPhone Fold expected to launch?
The iPhone Fold is expected to launch in mid-September 2026, alongside the iPhone 18 series, based on current leaks. Display panel mass production is slated for May 2026, with full device mass production targeted for July 2026. No official announcement or pricing has been confirmed by Apple.
The crease-free foldable display isn’t just a spec upgrade — it’s the condition Apple set for entering this market at all. If Fine M-Tec’s laser-drilled plate delivers in production what Samsung Display demonstrated at CES 2026, Apple won’t just be joining the foldable race. It’ll be restarting it from a higher baseline than any competitor has reached. Every foldable that ships with a visible crease after the iPhone Fold launches will have a harder time justifying its existence. That’s the real story here — not just what Apple is building, but what it will make everyone else look like by comparison.
