If you want a signal for how far out the dreamy foldable phone that we can actually afford is, look no further than the prototype that TCL just unveiled at Mobile World Congress today. With a 7.2-inch flexible screen, it’s in the same size class as Samsung’s Galaxy Fold, and just like the Fold, the TCL prototype is not to be touched or even breathed upon by mere mortals. I’m a little surprised the company let me lift the glass surround to take a closer look at the thing. And, take note, I never saw this foldable device actually folding or unfolding: the thing on show at MWC can be more rightly classified as a folded phone prototype.

TCL is a bit of a complex company, given that it has one business that builds display panels — which does contract work for all sorts of consumer product manufacturers — and a separate consumer arm that designs and sells devices under its own brand as well as the Alcatel, BlackBerry, and Palm names. The MWC prototype comes from that latter operation: TCL is not just showing off the flexible OLED display, it’s here to convince people that its patented DragonHinge construction is the future of foldable device design.
