This time the latest news has been fetched by iPhone. The US Patent and Trademark Office has published an Apple Patent application for a foldable display. This, in fact, is in lieu of the earlier rumors that the company had been working with LG on a future foldable iPhone.

Spotted by Patently Apple and filed with the US Patent and Trademark Office(USPTO), the patent lays emphasis on an electronic device with a flexible display which can be folded in half. This again would be potentially be achieved using an optically clear flexible adhesive and a shape memory alloy or amorphous metal.

More specifically, Liquidmetal is mentioned as a possible material, which would make sense since Apple has long acquired exclusive rights to the amorphous material in consumer electronics, but so far has done little with it.

OLED might not have a permanent structure:

The patent also clearly mentions the possible presence of a Micro-LED display, which is definitely energy efficient, much thinner than OLED and has also been rumored for inclusion on an Apple Watch.

Now, Apple with its recent shift to OLED for the iPhone X won’t settle for any new technological changes, at least for the next few years. But, definitely, if a foldable iPhone doesn’t launch before 2020, it’s possible that a micro-LED could be used.

However, even after this, if the users are really waiting for a folding iPhone then Samsung could have a major head start, as it’s possible that the ‘foldable’ Galaxy X will launch sometime next year.
