OPPO Find N6 Introduces Crease-Free Technology, Claims World’s Flattest Foldable Display
Highlights:
- World’s flattest foldable display with a near “zero-feel” crease
- Titanium alloy dome hinge reduces hinge undulation to just 0.1mm
- Dome Memory Glass delivers 3× stronger durability with 99.9% shape restoration

OPPO has revealed the core technologies behind the OPPO Find N6, positioning it as the world’s flattest foldable smartphone. The company presented the new engineering breakthroughs during its Foldable Screen Crease-Free Technology Communication Conference, highlighting a series of innovations aimed at dramatically reducing the visible crease that has long been a limitation of foldable displays.
The main focus of the Find N6 is achieving a “zero-feel crease” display experience, where the fold line becomes almost imperceptible during everyday use. OPPO claims the new design significantly improves screen flatness compared to previous foldable devices, pushing the category closer to a truly seamless tablet-like display when unfolded.
At the center of this advancement is OPPO’s new-generation titanium alloy dome hinge. Unlike conventional three-axis hinge systems, the Find N6 uses a biomimetic symmetrical four-axis structure built with chip-level polymer 3D printing technology. This design reduces hinge surface undulation from 0.18mm to 0.1mm, helping the display maintain a flatter structure across the folding area while also improving the smoothness of opening and closing.
OPPO also introduced Dome Memory Glass, a new flexible glass technology designed to maintain screen flatness after repeated folding. The company says the material is more than three times stronger than traditional foldable glass and can restore 99.9% of its original shape after bending.
The device has passed 600,000 folding cycle tests and received TÜV Rheinland certification for crease performance, indicating strong durability alongside its improved flatness.
With these technologies, OPPO aims to push foldable displays closer to a truly crease-free design, potentially setting a new benchmark for the next generation of foldable smartphones.
