Apple’s Foldable iPhone May Use Dual-Layer Glass to Hide the Screen Crease

Apple’s first foldable iPhone could take a very different approach to one of the biggest problems in foldable devices: the visible screen crease. According to a new supply chain leak, Apple is developing a dual-layer glass design that separates the display from the hinge, potentially reducing wear and making the crease far less noticeable.

If accurate, this could be one of the key innovations that sets Apple’s foldable apart from existing devices.

A New Approach to Foldable Displays

Current foldable phones typically place the display directly over the hinge, which is where the most physical stress occurs. Over time, this pressure can create a visible crease and affect durability.

Apple’s reported solution is to physically separate the display layer from the hinge mechanism.

The design uses a glass “sandwich” structure, where the OLED display sits between protective layers rather than directly on top of the hinge. By creating this buffer, Apple can reduce stress on the display during folding and unfolding.

This approach could help maintain a smoother screen surface over time while improving overall durability.

Targeting a Nearly Invisible Crease

Previous reports suggested Apple is aiming for a crease depth of less than 0.15 millimeters, which would be significantly less noticeable than current foldable devices.

The dual-layer glass structure would make that goal more achievable. By minimizing the direct impact of the hinge on the display, Apple can better control how the screen bends and recovers.

The leak also mentions self-healing glass and a “traceless” hinge, indicating Apple is exploring materials that can recover from minor deformations and reduce visible wear.

Advanced Materials and Engineering

The foldable iPhone is expected to feature a liquid metal hinge, a material known for its strength and resistance to fatigue. This could allow Apple to build a thinner device without sacrificing durability.

These engineering choices highlight how Apple is focusing heavily on long-term reliability—an area where many foldable devices still struggle.

A Larger, iPad-Style Experience

When unfolded, the device is rumored to feature a 7.8-inch internal display with a wider aspect ratio designed for multitasking and media consumption.

Apple is expected to pair this with an iPad-style interface, allowing users to run apps side by side and take advantage of the larger screen.

The outer display is rumored to be smaller, around 5.3 inches, providing a more compact experience when the device is closed.

Touch ID Instead of Face ID

To keep the device thin and make room for a larger battery, Apple may remove the internal components required for Face ID.

Instead, the company is expected to bring back Touch ID, integrated into the side power button. This would simplify the internal design while still offering secure authentication.

A Premium Device With a Premium Price

All of these advanced materials and engineering solutions come at a cost.

The foldable iPhone is expected to launch in late 2026, likely alongside the iPhone 18 Pro lineup, and could become the most expensive iPhone Apple has ever released.

With its combination of new display technology, improved durability, and a hybrid iPhone-iPad experience, Apple appears to be aiming for a product that justifies its premium positioning.

Final Thoughts

Apple isn’t just entering the foldable market—it’s trying to solve its biggest flaws.

By redesigning how the display interacts with the hinge, the company may finally address the crease issue that has defined foldable devices so far. If successful, this approach could make Apple’s first foldable iPhone feel more refined, durable, and closer to a traditional smartphone experience than anything currently available.
