We tried a new foldable phone with a 10-inch screen that folds in different directions - CNET, Cnet.com

TCL gives us a brand new foldable design we’ve never seen before.

I’ve opened and closedfoldable phoneshundreds of times by now. But even afterreviewing the Galaxy Fold(twice), playing withHuawei’s Mate Xand bending slim concept designs, nothing has prepared me forTCL’sprototype dual-hinged phone, which folds in three parts and opens into a huge, 10 – inch tablet.

The most remarkable thing about TCL’s phone is that the hinges themselves move in different directions. TheDragonHinge fold in, like a book, or like theGalaxy Fold, while the Butterfly Hinge folds the opposite way.

) The two hinges create a zigzag shape as you open and close the device, a silhouette in Z. It looks like an accordion. Ora taco holder. And I have to get my greedy hands on it to give it a fold, one panel at a time: Open. Folded over once. Completely folded up into a triple-stacked sandwich so that the exposed panel becomes the TCL phone’s “outer” screen. With this design, a single uninterrupted screen does it all.

As with other foldable phones, the act of folding feels physical and visceral in a way that makes me appreciate the engineering feat of any company attempting to make devices whose screens bend in half.

Foldable phones are the next frontier in phone design, delivering at least double the screen space in a package that’s practical enough to tote around. Unfolded, the large screens promise an expansive display for reading, watching videos,gamingand multitasking. Folded up, you can use them on the go. Despitevery real fears over screen damagethat could send lofty foldable ambitions crashing to the ground, device-makers are scrambling to push out their own new designs – to bag reputation points as much as to capture buyers’ attention.

It’s into this mix that TCL is dropping its wild new prototype. Best known for makingreally good , affordable TVs, TCL is nowaligning its phone businessunder the same brand. The company has already trotted out concept designs and announced its DragonHinge months before this particular dual-hinge effort.

TCL’s daring trifold prototype is just the start

TCL’s prototype design doesn’t have a name, a price or a target window for production. It doesn’t even have a working screen. All that will come. For now, I’m mesmerized as I work the hinges with my hands, and imagine what it’d be like to use a triply folding device.

Folding one panel under, for example, could turn a portion of the screen into a digital keyboard while you use another part as the display . When you fully close the phone, you’d be able to use it as a really chunky handset.

Yes, you’ll see creases when it’s open – and no, we still don’t have bendable glass to better protect the display. That raises questions about the wear and tear on a device with a plastic cover material that’s exposed to sharp objects, damage from pressure and the elements, like rain and dust. These are the same issues that plagued the $ 1, 980 Galaxy Fold and spurredSamsung to retrofit its foldable phone to make it sturdierthan its first attempt.

For now, there’s no consensus on what the “best” foldable phone design is, and that’s what makes this all so exciting. We’re in the Wild West phase where any prototype or concept goes, from thevertically folding Motorola Razrthat CNET discovered will come out by the end of 2019, to thesquare foldable phonethat Samsung’s rumored to be building.

Microsoft, too, has its bookish(Surface Pro Duo)slated for 2020 and Chinese brandXiaomi wowed us with an early conceptthat has you folding back two side display panels behind a center panel.

When and if it becomes a real product, TCL’s prototype will face distinct challenges with ensuring sturdy construction, a semiaffordable price and a sales plan to put the biggest foldable phone we’ve seen yet in front of real buyers. But enough reality for now. I let the teeming questions slide from my mind and give the Butterfly Hinge one more fold.
