Multi-layered screen
Nano-textured glass can already be found on the iPad Pro, iMac, MacBook Pro and Apple’s external screens, among others. For the first time, this technology is also applied to the iPhone. It has a scratch-resistant coating and a nano-textured top layer, which is made from a specially developed polymer that is up to 40% stiffer than common materials.
There is high-strength glass above and below the folding screen, and the different layers slide over each other when you fold the screen, similar to how the pages of a book move when you open it. As a result, there is hardly any tension on the screen. For extra strength, there is also a titanium plate at the bottom. However, the device is equipped with Ceramic Shield glass on the outside and back.
Nanotexture on the inner screen
The nanotexture of the iPhone Duo is not a separate matte coating, but a finish that is incorporated directly into the screen structure. Apple calls it a nano-texture finish on the inner screen, intended to reduce glare and improve the viewing experience.
In practice, this means that incident light reflects less strongly. Especially when you work in the sun or under bright indoor lighting, the screen remains easier to read from different angles
Positive effect: The fold is less visible
With a foldable device, the fold line is often the most disturbing part of the image. Apple says the nano-texture also helps make that crease visually less noticeable, so the interior panel looks calmer and more consistent. This effect is extra interesting because the inner screen consists of ten ultra-thin layers that can move independently of each other. According to Apple, this construction contributes to the strength of the panel and to reducing reflections.
No coating, nanometer level
The way Apple applies the nanotexture is very different from traditional matte screens. Most matte displays simply apply a coating that scatters the incident light. The downside is that such coatings can reduce sharpness and contrast, sometimes leading to a strange, glittering haze over the contents. The coating can also peel off over time.
This is not the case with Apple’s nanotexture. The structure is etched directly into the surface at the nanometer level. This effectively scatters incident light and keeps reflections to an absolute minimum, while maintaining image quality, sharpness and color reproduction. This way you always enjoy a perfect image on the inner screen of the iPhone Duo, regardless of the lighting conditions.
