TCL’s zigzag concertina-style folding smartphone has one screen and two hinges

CNET

TCL, the company best known in the mobile world for holding the license to make BlackBerry devices, has made no secret of its foldable phone plans. It has shown off, and talked about, folding smartphones and the hinges that are so essential to their operation since the beginning of the year. Now it has revealed a spectacular new type of folding device design, and it’s unlike any we’ve seen before.

Take a look at the photo. The TCL phone, which is strictly a concept and does not have a name or release date, has a dual hinge that unfolds the massive 10-inch screen, concertina-style. Like the Huawei Mate X, the TCL device has a single screen, but here there are two hinges splitting it into thirds. Open, it has a single, 10-inch expanse of a display, while folding it down once lessens the screen real-estate, and for a second time gives you a thick, single-screen viewing experience. That’s a lot of versatility, and plenty of potential for media viewing and productivity use.

The TCL phone shown to CNET was not a working version, therefore should be treated as a concept of what’s possible, rather than an example of what TCL will release in the future. The brand announced its first phone — the TCL Plex — to wear the TCL name in September, and in an interview with Digital Trends at the time, said it would be ready to talk about foldable phones during Mobile World Congress 2020, which will take place at the end of February. However, more details about its screen technology will likely come at CES 2020 at the beginning of the year. We may not have long to wait before we see if this is representative of what TCL will launch over the coming year.

TCL’s zigzag concertina folding smartphone is very unusual, and another in the growing number of experimental folding phone designs we’re seeing. TCL has also shown off other folding phone designs that use a single hinge for either vertical or horizontal use, while it’s almost certain Motorola will introduce a vertically folding smartphone at an event on November 13. Xiaomi has teased an intriguing folding phone design in the past too, and Microsoft turned everything on its head with the dual-screen Surface Duo. The Galaxy Fold and Huawei Mate X are only the beginning.

What will your smartphone look like in 2025?
Galaxy Fold

While smartphones are set to continue fulfilling an important role in our everyday lives, our constant companions could use a makeover. Maybe it's time for a new form factor. Perhaps this evolutionary branch of the smartphone tree has grown to its full potential, or maybe there are more refinements to come that will elevate this tired look to new heights.

There are some trends in play that may reach their zenith in 2020, but what happens beyond that? What will our phones look like in five years' time?
Wave goodbye to ports
Ports take up space and constrict phone designs, while also letting in water and dust. Little wonder that phone designers don't much like them. Apple wasn't the first to experiment with ditching the standard 3.5mm audio jack, but despite complaints when it erased the headphone port for good in the iPhone 7, almost every other manufacturer has followed suit. Much to the chagrin of audiophiles, the standard headphone port is heading for extinction in phones. Glance at the meteoric rise of Apple's AirPods and other Bluetooth headphones and you can see what may have driven the decision to ditch that port, but the manufacturers aren't the only ones to benefit.

CES is not usually a technology trade show that has a wealth of new smartphones, but several companies did arrive at the 2020 version with new phones to show us. Not only did we see devices we’ll actually be able to buy, but we also saw some concepts and early previews of hardware that may arrive in the future.

Let’s take a closer look at all the mobiles we saw at CES, whether they’ll be here tomorrow or if they're just glimpses of what may come in the near future.

TCL is working on more than 30 different folding phone concepts
TCL folding screen prototype CES 2020

Folding phones seem poised to take off in a big way. Most phone manufacturers see the emerging folding screen category as the future and you can count TCL among them. In addition to a trio of TCL-branded 10 Series phones, the Chinese manufacturer also showed us another new folding screen device at CES 2020.

For all the excitement about this new design direction, the ideal form factor is far from certain. Do we want a folding phone with an external display that opens to reveal a tablet-size screen, like the Samsung Galaxy Fold? Do we want a clamshell design that makes phones more portable again, like the new Motorola Razr? Or will the first must-have folding mobile device be something altogether different?
