Oppo recently debuted the Oppo Find N6 foldable with a crease that is almost negligible in daily use. It’s not completely invisible, but it’s subtle enough that many users barely notice it while scrolling or watching videos. Even Apple is rumored to use a similar display technology in its first foldable, which could launch this September.
However, the Cupertino giant appears to be even more serious about making this display the best it can be.

Apple iPhone Fold will use multiple layers of protective layers between the display
According to supply chain reports shared by tipster Digital Chat Station, Apple’s foldable display could use a dual-layer glass structure built from UTG (Ultra Thin Glass) and UFG materials.
In simple terms, this means the screen may consist of multiple glass layers rather than a single thin sheet. The display panel itself would sit between these layers instead of being placed directly against the hinge mechanism.

This design could help solve one of the biggest problems with foldables: durability. When a foldable phone bends thousands of times during its lifetime, the pressure around the hinge can gradually create a visible crease in the middle of the screen. By separating the display layer from the hinge area and using multiple glass layers, Apple may be trying to reduce stress on the panel.
The rumored display may also include a form of self-healing glass. The idea is that the display could gradually smooth itself over time, helping it maintain a cleaner look after repeated folding.
Oppo did something similar with the Find N6, which it says uses Auto-Smoothing Flex Glass, where the crease slowly smooths itself out over time.
None of this is confirmed yet, and Apple rarely comments on products before they launch. But we know for certain that a foldable iPhone is coming.
