Is it safe to use a screen protector on a nano texture display?

Consider that the optional nano-texture screen is intended to reduce screen reflection and glare from external light sources. By contrast, the standard glass option already benefits from Apple's very effective and robust anti-reflection and hard-coat surface treatments.

As the uppermost glass/air interface is the optical surface is primarily the source of screen reflections, applying any kind of film or Screen Protector over Apple's nano-texture screen will entirely defeat the benefits of reduced screen reflectivity introduced by the nano-texture glass.

Applying any kind of adhesive product to the nano-texture screen can potentially damage the screen finish.

—Is this stated anywhere by Apple?

This is the only Apple document I can find: If the screen isn't working on your iPhone or iPad - Apple Support and it does not mention NTD.

We are not Apple but, in the many years I've volunteered here. I've lost count of the number of reports of people removing an aftermarket screen "protector" only to find that it has seriously damaged/removed part of the display coatings, or left residue behind that stubbornly resists cleaning.

—were I to claim that my NTD screen was damaged after removing a screen protector - would it be covered by warranty? or considered my fault?

That Apple's call but, again, experience says you will likely take a hit to your bank account for that.

Ask the maker of the protector if:

> they will step up and take responsibility, paying for any damage repair or device replacement, and

> if they recommend they product be used on an NTD.

Those are question directed to the protector's maker, not a part-time sales clerk in a strip-mall computer store.

By the way, Apple won't answer this in these forums. You have to call them.

If you are so concerned with this issue, I recommend skipping the NTD option.

To be clear, I did not indicate that applying an adhesive product to the nano-texture screen would cause damage.

I stated that applying an adhesive product to the nano-texture glass had the potential to cause damage.

Without delving deeply into material and adhesive science, perhaps suffice to understand that the nano-texture glass is not smooth. At a microscopic level, the glass has been eroded to produce a roughened surface that is designed to disperse light that reflects from the front (rough) glass-to-air surface of the screen. Adhesives can potentially leave residues within the roughened surface that may be difficult (or impossible) to remove.

Any external damage occurring to an iPad or its screen will be interpreted by Apple as accidental damage - and therefore will not covered by Apple's product warranty.

Third-party testing of Apple's standard and nano-texture screen has demonstrated that the standard glass is considerably harder and more resistant to scratches and blemishes than the nano-texture finish. The nano-texture finish is much softer than regular glass - and as a consequence is more easily damaged.
