Unfolding the first trifold phone

Folding phones are boring. Look we've had the firstwave of foldable devices and they're neat, but you'veseen all that already. This is about what comes next after the current generation of foldables. Sling like the tri-fold from TCL, a wild new concept, foldingtablet, phone thing. (techno-music) Unlike most foldables thetri-fold has two hinges, which lets it fold up into thirds . You can use it as a phone, you can unfold it onceto use as a bigger screen or fold the unfoldedinto a full size tablet. It's not a half way compromiselike some of the other foldables that we've seen which basically turn into just slightlywider phone displays.

This is a full blown tablet. It's nearly as big as an iPad, but you can still fit it in your pocket. The screen folds from a 10 inch tablet down to 6.65 inch phone. You could also open it two-thirds the way and ya know prop that up it'll auto rotate so you can use in whateverorientation you want. There's a lot of weird use cases that you could probably use this for. The screen on this one is a 3k panel, but again that's just this prototype. We have no idea if the finishedversion will have that, but the tri-fold shows justhow hard it's gonna be to turn these ideas into reality. I've gotten to play aroundwith the prototype for a bit and it's really rough to use right now. It is incredibly heavy for a phone. It's got those big metal hingesand there are three separate batteries to power all those displays, it's basically three phones. And even though it's reallythin as a tablet the phone mode is super thick and that'sbefore your worrying about things like the software, which is basically non-existent. Durability which is a huge question or price which who even knows. (techno music) But looking even further into the future.

TCL also had a very earlymock up of a rollable phone. This is really cool ideathat's a phone that has a fully flexible display thatslides around the side and behind the phone. And it could roll back outand become a larger display when you need more space. The way it will, in theory, work is that there's gonna be motorson the inside of the phone and you'll press a buttonand it'll expand out from a 6.75 inch displayto a 7.8 inch screen. Now that doesn't sound like alot, but your actually getting almost double the screen spaceit's almost twice as wide.

The whole system is actuallypretty similar to the rollable Oled TV that LG's beenshowing off for years. Now again this is a really early concept, it's not even a functionaldevice, just plastic and a screen that's literallyjust a sheet of paper. Is this a good idea? Who knows. It does avoid some of theissues of current foldables, like those easily breakable hinges and the creased display which is cool. But it's almost guaranteedto have issues of its own. Moving parts they're tricky. Now the tri-fold isjust a proof of concept and the plastic sliding one even more so. You won't actually be able tobuy either of these devices and it's not clear if TCL'sactually gonna make products based on these concepts in the future. So why should you care. Well, first of all, because it's cool. I mean look at this thingit's a phone that unfolds into a giant full size tablet. And it actually turns on and runs android, it's like a science fiction prop.

But it's also important,because TCL is planning on eventually makingfoldable and rollable phones that might actually look like these. Possibly as early as next year. The company says that it'sexperimenting with dozens of different form factors right now. So it's possible that phones like these, could be real one day. Look phones have basically been the same for the last decade. Black boxes with touch screens. Devices like the tri-foldor that sliding concept, even if they're not here yet, show off what the future phones might one day look like. And that's really exciting idea. Thanks so much for watching.
