Apple’s Foldable iPhone Could Feature Tougher Display Tech Than Samsung—Here’s Why That Matters

The tech world is buzzing with anticipation as Apple reportedly weighs a game-changing decision for its first foldable iPhone: using a more durable display protection solution that could leave Samsung’s Galaxy Z Fold in the dust. According to a bombshell report from The Elec, Apple is seriously considering transparent polyimide (PI) film as the protective layer for its ultra-thin glass cover—a move that could redefine durability standards in the foldable phone market.

The Material Showdown: PI vs. PET

Right now, Apple is evaluating transparent polyimide film against the more common polyethylene terephthalate (PET) film that Samsung uses across its foldable lineup. This isn’t just a minor spec bump—it’s a fundamental choice that could determine whether the iPhone Fold survives the real-world test of daily use.

The protective film sits directly on top of the ultra-thin glass, making it the layer users actually touch every single day. While ultra-thin glass offers superior visibility compared to plastic alternatives, it’s notoriously fragile and prone to shattering. That’s why this protective layer is absolutely crucial for both durability and user experience.

Industry insiders suggest that transparent PI film is currently the frontrunner for Apple’s foldable. This represents a clear differentiation strategy from competitors. Although more expensive than PET film, transparent PI offers significantly higher surface hardness and superior scratch resistance—potentially addressing one of the biggest complaints users have had with foldable devices since day one.

Why This Could Be Apple’s Secret Weapon

Let’s be real: foldable phones have had a rocky reputation when it comes to durability. The crease down the middle, the vulnerability to scratches, and the fear of screen damage have kept many potential buyers on the sidelines. Apple knows this, and they’re apparently ready to strike back with technology that could make the iPhone Fold the most durable foldable on the planet.

The higher surface hardness of transparent PI means it can better withstand the daily wear and tear that foldable phones endure. Think about it: keys in your pocket, accidental drops, constant folding and unfolding—all of these are potential screen killers. A tougher protective layer could be the difference between a phone that lasts two years versus one that starts showing wear after six months.

The Supply Chain Power Play

If Apple does go with transparent PI film, Kolon Industries is emerging as the likely supplier. This isn’t just any supplier—Kolon built the world’s first mass production line for this material and has been anticipating strong demand in the foldable market for years. Interestingly, the industry term “CPI” (colorless PI) is actually a Kolon Industries product name, showing just how dominant they are in this space.

Meanwhile, China’s Lens Technology will probably supply the ultra-thin glass itself and may handle the critical process of bonding the final protective film to the glass. When Apple previously considered PET film, Lens Technology reportedly proposed producing that material directly as well, showing they’re ready to adapt to whatever Apple chooses.

The Samsung Connection

Here’s where things get really interesting: Samsung actually used transparent PI film for its first Galaxy Fold in 2019 but switched to ultra-thin glass with PET film protection starting in 2020. This shift actually reduced demand for transparent PI film industry-wide, but Apple’s potential adoption could reverse that trend and make PI film the new gold standard for foldable displays.

Samsung’s decision to move away from PI film was controversial at the time, with some industry experts questioning whether it was the right move for durability. If Apple’s testing confirms that PI film offers superior protection, it could be seen as validation that Samsung made the wrong call.

Market Impact and Timeline

Apple’s final decision on the protective film material could come soon, as the company continues testing components for the foldable iPhone. The device, likely called iPhone Fold, is expected to launch in the second half of this year alongside iPhone 18 Pro models—a launch window that’s been confirmed by multiple reliable sources.

The timing is perfect for Apple to enter the foldable market with a technological advantage. Samsung has had years to refine its foldable technology, but Apple could leapfrog them with superior materials science. This is exactly the kind of bold move that Apple fans have come to expect from the company.

What This Means for You

If you’ve been waiting on the sidelines for a foldable iPhone, this durability upgrade could be the tipping point that makes you finally pull the trigger. A phone that can withstand daily use without showing wear would be a game-changer for the entire foldable category.

The choice between PI and PET film might seem technical, but it has real-world implications for how long your expensive new device will last and how good it will look after months or years of use. Apple’s reputation for quality means they’re unlikely to compromise on something as fundamental as display durability.

The Bigger Picture

This decision reflects Apple’s broader strategy of entering established markets and immediately setting new standards. Just as the iPhone revolutionized smartphones and the iPad transformed tablets, the iPhone Fold could establish new benchmarks for what foldable devices should be capable of.

The transparent PI film choice would signal that Apple is willing to invest in more expensive materials to deliver superior user experiences—a philosophy that has served them well throughout their history. It’s not about being first to market; it’s about being the best when you arrive.

The foldable iPhone revolution is coming, and it might just be tougher than anything Samsung has to offer. Stay tuned, because this is going to be one wild ride.
