TCL has developed a foldable smartphone concept that has dual hinges that fold in opposite directions like an accordion.

The device which folds in three parts and opens into a 10-inch tablet. The phone's hinges move in different directions. The one folds in, like a book, while the other folds the opposite way. But you can also fold all of the screens together so you have a form factor that looks more like the phones we're used to.

The specific prototype originally appeared at IFA last September, CNET posted some photos of it just this week.

Provided the technical challenges faced in the manufacturing of the bi-fold phones have run into so far, do not expect this phone to be available any time soon.

We still don't have bendable glass to better protect the display, and the plastic covers for the screens are generally sensitive to the wear and tear. Samsung may start using bendable glass in its next foldable smartphone.
