Apple's upcoming foldable iPhone will use a dual-layer ultra-thin glass structure to reduce display crease visibility, a new supply chain rumor suggests.

According to Weibo-based leaker Digital Chat Station, Apple's first book-style foldable will feature two layers of ultra-thin glass (UTG) or ultra-thin flexible glass (UFG), with the display sandwiched between them, isolating it from direct contact with the hinge. The arrangement is designed to spread mechanical stress across multiple layers rather than concentrating it on a single sheet, which could improve durability and reduce visible creasing over time.

The approach would be a departure from most current foldables, which typically use a single UTG layer that must simultaneously handle bending forces and protect the display underneath. Decoupling the display from the hinge mechanism could also help Apple meet its reported goal of making the crease almost imperceptible – though more recent reports have pushed back on past "crease-free" claims.

As we reported in December, Apple has been testing next-generation UFG with variable thickness, with a thinner layer at the fold for flexibility, and a thicker layer elsewhere for rigidity. The latest rumor suggests Apple has developed a composite glass stack rather than relying on a single panel alone.

The foldable iPhone is expected to launch later in September alongside the iPhone 18 Pro lineup, although recently one analyst claimed the device could be released closer to December.

The device is expected to feature an approximately 5.3- to 5.5-inch outer display and a 7.8-inch inner screen. It will reportedly use liquid metal hinges to achieve a virtually crease-free display and is expected to be priced between $2,000 and $2,500, making it Apple's most expensive iPhone ever.

I think both foldable iPhone and Z Fold 8 will have a crease-less display and soon all foldable devices will be crease free. Hopefully the durability of foldable iPhone will be high. Repair costs on the foldable with or without Apple Care will be high. Think the foldable iPhone will launch at $1999
 
Great to hear this. Apple always does the best to get their product quality done well and looking good! I trust the unfolded screen looks glassy. Samsung Fold Z when unfolded looks like plastic made due to Samsung uses Ultra Thin Glass (UTG) layered with plastic polymers so the screen can bend.
This creates:
• A softer, slightly glossy surface
• More reflections
• A look that resembles plastic rather than glass

I estimate the Apple Care plus higher for foldable due to higher broken and repair risks compare to regular phone. This makes sense especially for the first generation. However, I am looking forward to own the first generation iFold!
 
Given how good edge to edge displays have become. I was expecting a fancy articulating hinge the locked them perfectly together when open with no noticeable crease or gap.

Can they fold the starting price too?

I’ll wait until they create the transformer iPhone that unfolds multiple times to become a 16 inch iPad!
 
Given the killer app for the middle screen on Android seems to be multitasking, it seems prudent to sidestep the crease and just make a dual-screened iPhone.

Apple etc are trying to solve a problem Nintendo figured out 20 years ago.

It’s still gonna have a crease people 🙄
Of course it will. It's just materials physics. It just comes down to how perceptible the crease is. Unless the screen is a completely flexible/fluid material, and is somehow actively pulled taut once the screen is opened fully, the fact that there is a hinge means there will be a crease or a sag, which will increase over time. Or the material is completely inflexible, and there are two distinct sides, one each on each inner face on the phone, and some way of hiding the join between the two sides. The question is if this can be imperceptible to your eyes.

It's like "no bezels", but a phone is a 3D object, so there'll always be sides. You can have imperceptibly small bezels, or you can fold the screen over the sides, but there'll still be sides.

Sorry, my brain cannot comprehend this lol, glass that you can fold into a sharp crease and it doesn't shatter or crack.....

Then again I am wearing an Apple Watch with a 3D printed Titanium case.....

The price is way too high

Apple had patent usage for something know as “Liquid Metal”, I suspect the hinge mechanics may utilise this tech more than just the SIM ejector pin.
 
This is the iPhone of my dreams. a Big iPad display when I need it and not a huge brick falling off my pocket.
Same here, looking forward to this. On the other hand, I do wonder if an iPad Pro + iPhone Air or something like that is gonna be even more attractive in the end.

It depends on many factors it’s just not what one initially thinks about.
 
Without a doubt this will start at $2000 USD
I like many don’t upgrade every year so a bump in pricing after waiting 2-4 years for something new from Apple seems worth it to some. If you purchase an iPhone 17 Pro and looking to upgrade due to FOMO then that’s on the individual.

Yet no one is looking for three individual similar sized screens on a single folding device. Maybe this device is not suitable for some people’s usage but hey the world will continue to turn.
 
Let’s be honest this would be the first truly new thing Apple has done in the iPhone space since the original launch. You can complain about the price all you want, but if you’re even remotely into tech, you can’t seriously sit here and say this doesn’t intrigue you at all. Not saying everyone needs it, that’s totally fair. But this is a genuinely interesting piece of tech. And the people instantly writing it off? Yeah… that feels a lot more like future FOMO than anything else.

as soon as a heard “virtually crease free” I knew it would still be the same as other fold phones.
