Apple is pushing deeper into foldable phone development, and the focus is clear. You get a screen that does not show an obvious crease. To reach that goal, Apple is now testing a new type of ultra-thin flexible glass that aims to fix one of the biggest problems with foldable displays.
This new material uses uneven thickness across the panel. The glass stays thinner around the fold so it bends more easily. Other areas remain thicker to keep the display rigid and durable. The idea is simple. Spread the stress instead of forcing it into one line where a crease usually forms.
According to Digital Chat Station, Apple is actively evaluating this glass design for its book-style foldable iPhone. The leaker says Apple wants a screen that looks “visually crease-free” during normal use. That phrase matters because most foldables today still show a visible line, even when the display is on.
Apple Is Testing
Apple’s current testing phase does not signal a delay. Instead, it suggests the company is validating risky parts while core hardware decisions stay locked. This stage often focuses on long-term durability, production yield, and real-world stress testing.
The report explains that Apple may already have improved ultra-thin glass ready as a backup. Testing flexible glass now likely helps Apple confirm whether this new approach meets its internal quality targets. Chinese display makers are also evaluating similar solutions, which points to growing confidence across the supply chain.
Foldable iPhone
The foldable iPhone is expected to use a book-style design. Reports point to a roughly 5.3 to 5.5-inch outer screen and a 7.8-inch inner display. Apple also plans to use liquid metal hinges to support the push toward a nearly invisible crease.
Pricing will be high. Estimates place it between $2,000 and $2,500. If Apple succeeds, you get its most expensive iPhone yet, built around one clear promise: a folding screen that looks smooth, flat, and finished.
