The age of folding smartphones is coming. We know as patents for foldable phones are being filed in an ever increasing number, with all the big players like Apple, Huawei, LG, Motorola and more positioning themselves to come to market in the strongest and most innovative position possible, with the Samsung Galaxy X being perhaps the most well known.
Here we've rounded up the five most exciting pieces of mobile foldable hardware that we currently know about.
1. Samsung Galaxy X
Revealed in an official tease, and then reportedly receiving a release date in 2019, the Galaxy X is one of the most exciting of the incoming foldable phones. According to reports out of Korea, the X is extra interesting as it supposedly has three screens instead of two, essentially delivering a device that transitions from a phone to tablet.
The front of the Galaxy X reportedly has two 3.5-inch screens, which become a 7-inch tablet when folded. The rear of the device has a third 3.5-inch screen that allows it to be viewed even when folded down. This indicates that the device will work via a series of intricate hinges.
2. Motorola Razr
As T3 recently reported, Motorola looks like it is currently working on a folding phone, and all signs point to the fact that it could carry the iconic Motorola Razr branding. Back in Frebruary 2017, Yang Yuanqing, the CEO of Lenovo (which owns the Motorola brand) noted while speaking to TechRadar that:
"With the new technology, particularly foldable screens, I think you will see more and more innovation on our smartphone design. So hopefully what you just described [the Motorola Razr brand] will be developed or realised very soon".
What followed next was Motorola filed a patent for a two-screen folding phone, that when flipped out (see above image) can also be used as a tablet. The patent details how the device has two cameras, top, bottom and middle hinges, and the ability to be propped up into a tent-like display mode.
The emergence of this patent is interesting when you take into account recent Motorola Razr concept videos, like the one below, which have tended to lean more on the traditional flip phone form factor. A phone that folds out into a tablet, though, feels more on-trend for the modern market, so makes sense to us here at T3.
3. LG folding smartphone
LG is currently a leader in rolling, foldable displays, with not only the company showing off working examples (see above image), but LG Display screens even apparently being utilised by other brand's folding devices, too (such as the Huawei folding phone).
This makes it unsurprising that in January this year LG filed a patent that shows off a "mobile phone with a flexible display which can be folded in half", before detailing two different potential designs.
The first model depicted is a folding phone that features a camera system embedded in the backplate, with information like the time displayed on its front when folded in, while the second shows a device with a transparent section on the right-hand side of the front that could be used to display notifications and time, too.
The LG foldable phone, no matter which form it comes in, looks like it will feature just two screens rather than the Samsung Galaxy X's three.
4. Apple foldable iPhone
Arguably the biggest player alongside Samsung that appears to be working on a foldable device is Apple, and the really exciting thing is that the hardware may very well be close to realisation.
That's because in November last year an Apple Inc-filed patent emerged for "Electronic Devices With Flexible Displays", which specifically details an electronic device comprising "a flexible display in the housing having a bending region that bends about a bend axis".
The device also states that the flexible display technology could be utilised in "a cellular telephone".
Unlike other patents there are no images of the flexible display or the devices it could be being utilised on. However, with Apple's strong track record of innovation, we wouldn't be at all surprised if the Cupertino maker drops an folding iPhone-iPad tablet out of the blue.
5. Huawei folding phone
Last, but by no means least, is the folding phone that Huawei is working on. Last October, CEO of Huawei, Richard Yu, confirmed that the Chinese maker already had a working prototype of a flexible smartphone, and then in March of this year patent diagrams of a foldable Huawei phone emerged.
The patent refers to the device simply as "foldable smartphone", but clearly shows a book-like phone that can be opened up to create a larger tablet, with a smart Surface Book 2-style hinge connecting each of the folder's two screens.
Indeed, from what we can see here at T3, it looks like solving that hinge design is the key to producing a successful foldable phone right now, whether or not it uses two or three screens. Any hinge would need to be as compact and invisible as possible to make the device a game changer, as the last thing anyone needs is some clunky PDA-style block stuck in their pocket.
The idea of carrying around both a high powered phone and tablet in one, though, is tantalising, and we hope that Samsung, Apple, Motorola, LG, or Huawei can deliver.
