As CNET points out, it ends up looking something like a Z or a taco holder. 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, only it’s a thick stack of screens.
While it’s great to see companies experimenting with new form factors, don’t expect this phone to be available any time soon. It doesn’t have a name, projected release date or even a working screen. If and when those things fall into place, the tri-fold phone will face challenges that bi-fold phones have run into, mainly how to protect the display as the device folds repeatedly.
