TCL’s rollable concept phone is magical - Android

As foldable phones slowly become more commonplace, we’re starting to see new concept devices aiming to solve problems still unsolved by non-foldable rectangles. The Galaxy Fold gets bigger. The Galaxy Z Flip gets smaller. And TCL, well, TCL has lots of ideas.

We’ve already seen a variety of weird foldable concepts from TCL, like the bifold, DragonHinge, and others. But we just got a sneak peek of a new concept that really has our attention.

TCL’s new rollable concept phone starts off looking like a pretty average smartphone with a 6.75-inch display. Use the right gesture, however, and it expands to a 7.8-inch tablet.

Unlike most foldables, which open or close like a book or clamshell, the new rollable concept hides the flexible OLED display inside the phone and uses a motor to expand the chassis and roll out the display. In use, the process is pretty magical and gives the impression that the phone is expanding out of nothing. It’s pretty cool.

Unfortunately, we were only able to play with a dummy unit that had no working motor, nor even a working display. This means we had to physically pull the display open by hand, as shown in our gif above. TCL does have a working prototype of this device, but the unit got stuck in Wuhan, China, and couldn’t be shipped to the US for display.

TCL says that while the concept device won’t be commercially available any time soon, it’s been working on perfecting the rolling mechanism.

While the Samsung Galaxy Z Flip has done well to show consumers how foldable devices can be commercially viable, TCL doesn’t want to have another Galaxy Fold situation. That means TCL’s rollable display will remain under development at least until next year.

TCL also showed us its Tri-Fold foldable concept device, which it’s been working on for a while now. This concept is unique and targets an entirely different user group. It starts as a mostly normal-looking phone, though it’s about as thick as three phones piled on top of each other. Pull it apart like an accordion, and you’ll find you’re holding a massive 10-inch tablet.
