Apple is looking into building foldable iPhones out of glass – BGR



Samsung wasted the opportunity to become the first major smartphone vendor to launch a foldable handset, as the Galaxy Fold turned out to have a few design flaws that compromised the screens during regular use. It's not that Samsung had the best foldable phone design out there, but the Korean has been at the forefront of foldable smartphone hype for years.

We've been waiting for two years for the Galaxy Fold to arrive, but Samsung kept pushing the launch event as it was still perfecting the phone's design and software. Making foldable handsets, as it turns out, is easy, and the Galaxy Folds early misfortune is a testament to that. On the other hand, Samsung does deserve some praise for pushing the envelope when it comes to new form factors. Someone had it, regardless of the risk.

But Samsung is hardly alone, as everyone else in the business is working on such devices, including Huawei, which unveiled its Mate X at the same time as the Galaxy Fold. One of these companies is Apple, which has been upgraded to working on foldable iPhones for quite a while.

The iPhone maker was just awarded a patent for a Foldable cover and display for an electronic device (US Patent No. 1

0,303,218). The documentation was filed on January 12th, and it is hard to find the first proof that Apple is interested in foldable handsets. New technologies are not included in any future devices.

Traditionally, electronic devices have a single form factor that may be driven by the size and shape of the display. Because many traditional displays are rigid or at least not flexible, a traditional device that is adaptable to accommodate multiple form factors includes the use of a mechanical hinge or pivot joint. These traditional configurations are used for traditional notebook and tablet devices, but are inherently limited by the integration and size required by a separate mechanical hinge.

Embodiments described here are directed to devices and techniques for forming portable electronic devices having a flexible cover coupled to. a flexible display that does not have the limitations or drawbacks associated with some traditional solutions.

The documentation reveals not only potential designs for flexible iPhones and iPads but also goes into great detail on how to manufacture flexible covers to ensure they both work as intended, and durable enough to protect the screen underneath the flexible glass.

Furthermore, Apple explains that several areas could be used at different times and that the device could be partially unfolded to the available screen size

The patent looks at various techniques for creating flexible cover sheets, listing several ceramic Materials that could be used for the foldable screens, including chemically strengthened glass, sapphire, or zirconia. What's interesting is that Apple focuses on glass / ceramic for the cover sheets rather than other materials, such as the Galaxy Fold and Mate X do not have glass displays.

Apple explains how these foldable sheets of glass would have been manufactured to ensure they can be found around an axis safely and survive the stress generated by repeatedly folding and unfolding the screen, and describing the complex system of layers of a flexible display

The document also looks at ways to ensure the finished product has a smooth surface, one that would improve the appearance of the device and the user experience.

Finally, the patent focuses on the cover sheet of the foldable device, which means it doesn't feature any details about the other important part of a flexib le gadget: The hinge. Then again, this is not Apple's only patent on flexible devices – just another piece in the flexible iPhone puzzle. That said, we'll have to wait and see if Apple will launch a foldable iPhone or iPad in the near future that will make use of any of the inventions described in this patent.
