Apple advancing all-glass iPhone with wrap-around display technology
Apple's future iPhone may have a wrap-around display, while also sporting an all-glass -- and perhaps port-less -- enclosure for a smooth exterior appearance.

Apple's design choices for the iPhone have always been widely debated by observers, with choices to implement specific styles and features often copied by competitors, such as the infamous notch. If Apple implements ideas outlined in a newly-granted patent, a future iPhone could end up being completely covered with seamless glass with zero penetrations for wired ports, and could even have a wrap-around display.
Apple iPhone with all-glass enclosure
In the patent, simply titled "Glass enclosure," Apple suggests how a handheld computing device could use glass for its casing. While images and discussions depict the old-fashioned click-wheel iPod, the filing also suggests it could be applied to practically any handheld device, like a smartphone.
Apple argues that a design challenge for device producers is that there is usually a need for case structures to involve multiple layers in a sandwich, attached by some sort of fastening mechanism like screws that makes assembly time consuming and cumbersome. There is also the suggestion that it there is a need to make a more aesthetically pleasing enclosure, yet durable.
The glass tube could have sections cut out before electronics are added.
Apple's solution entails creating an enclosure out of glass, but unlike iPhones with glass backs and side seams, the intention this time is to create one that doesn't rely on a multi-part enclosure. Instead, Apple wants to produce an enclosure that is one component, a potentially seamless casing.
The glass could be extruded in a tube, allowing for devices with round edges and a tubular body to be made. Depending on the implementation, the glass could have extra glass pieces placed at the top and the bottom of the tube, fully surrounding the electronics inside.
As the glass is extruded, this can allow for different body shapes to be created, including devices with curved edges that aren't flat. While there would be a seam at these cap joints, adhered by a laser bonding system, the main body of the glass would not have a seam going around it.
As it would be both the protection and the external casing, the glass could have varying properties, such as being transparent, translucent, and opaque in different areas. This would save from having to make an opaque section to hide elements from view within the casing.
The manufacturing process flowchart for the glass indicates Apple wants to create the hollow tube, then to cut sections out of the tube to enable specific features to function, such as speaker holes. The edges of the glass would be treated to create chamfered or radius edges, with the surface polished, texturized, protected with extra coatings, before the caps are placed and sealed.
As a bonus, proper material selection would allow for an iPhone enclosure that is totally transparent to radio emissions. This could theoretically increase Wi-Fi and wireless performance, or allow for smaller antennae in the unit.
Furthermore, an all-glass iPhone with no ports would have greater water resistance.
The filing was made on August 12, 2019, with its inventors listed as Christopher Prest and Emery A. Sanford.
Apple files numerous patent applications on a weekly basis, but while the existence of the filings indicate areas of interest for Apple's research and development teams, they don't guarantee the concepts will appear in a future product or service.
Apple has previous research on all-glass iPhones and wrap-around screens
The idea of a non-flat screen has been looked at by Apple quite a few times, and has surfaced in earlier patent filings.
For example, flexible displays have appeared in filings for foldable smartphones, typically involving a specific bend point and how to protect the fragile screen glass from cracking under strain.
It has also looked at wrap-around displays, which would take advantage of flexible display panels in a similar way to foldable devices. One filing from November 2019 mentions how a screen could wrap around the internal electronics.
Another from August 2020 went down the route of tubular devices with the wrap-around display, but added the suggestion the round shape could help make for a seemingly thinner device with a larger display area, as well as potentially being more accommodating to components of varying size.

Yet it never came to fruition
We’ve read these articles over and over just by a different writer
Apple already uses curved displays just not stupid curved like Sammy. Samsung dropped that turd because they read the Apple patent which I believe was used for iPhone 6, Apple Watch and Apple Park. Will have to refresh my memory as this info flew under the radar.
That’s always possible. But as it’s pointed our constantly whenever we read about a new Apple patent that looks interesting, not everything patented is used in a product. Many times R&D goes down a blind alley. For major companies. The $10 to 20 thousand it often costs to get a patent is trivial, so they take onc out to protect their R&D investment. My own company had a small bunch of patents, we did use them all, but when you get to the high tens of thousands, and hundreds of thousands, you simp,y can’t use them all. Apple bought scads of patents over the years too.
I expect Apple to check many things out without using them, or not using them for the type of product they were R&D’d for. Apple gets several thousand patents a year, so I’ve read. How many end up in products?
Apple can't even make a phone now that survives a waist-high drop. How is all glass even in consideration?
That's exactly what happened. Misunderstood and misrepresented rumors about Apple producing a "curved display" for the iPhone 6 spurred Sammy into rushing to market a hideous clone of the rumor, which no one asked for or wanted, and turned out not to be what Apple was doing at all.
