In a patent application published by the U.S. Pat. Patent and Trademark Office today, titled "Electronic Devices With Flexible Displays," says Apple's Foldable Smartphone Displays.
For example, Apple says it could not be lit by the pixels in that area of the screen. Alternatively, a "heating element or other heating structure" could be used, although Apple was not specific.
AppleInsidernotes that the foldable smartphone could have been a magnetic latching mechanism that would prevent the device from being folded or unfolded. This would be in environments "significantly below room temperature."
Apple files numerous patent applications every week, and many of the inventions do not see the light of day. Patents are therefore very detailed, encompassing many possible ideas, even ones. So, the exact implementation.
While unique, early foldable phones from Samsung and Huawei are in perfect condition, with bulky designs and expensive price tags. Apple is unlikely to release a foldable iPhone unless it can meet the company's strict quality standards.
Last year, Bank of America analyst Wamsi Mohan predicted that Apple is working on a foldable iPhone for release in 2020, while on an earlier Korean report said Apple was developing a foldable iPhone alongside LG. However, it's still not entirely clear, if it is true, it will not be the case.
