The Chinese electronics company revealed a prototype of the yet-named device as a part of the ThinkPad X1 line at its sold-out Accelerate conference in Las Vegas.
A press release categorizes it as a "full-fledged laptop with a foldable screen," that's powered by Intel and runs Windows, adding that "this is not a phone, tablet, or familiar hybrid."
The OLED 2K polymer display measures 13.3 inches diagonally unfolded and 9.6 inches when doubled over on a torque hinge.
Other details are sparse, but Lenovo offered a host of possible uses for a foldable PC, all of which revolve around it being a powerful, portable alternative to everything else on the market.
One possible issue that could prevent it from being a big hit with mobile workers is the lack of a physical keyboard.
One of the challenges with building a foldable-display PC, as opposed to a foldable phone, is that users will be looking for adequate keyboard solutions.
With this device you can use it as a clamshell laptop, but the default keyboard is an on-display, touchscreen keyboard.
You can also use it as a two-in-one, where you prop it up as a tablet and then use a Bluetooth keyboard. You can use it as a large tablet, or slightly folded like a book.
Considering that review copies of the Samsung Galaxy Fold smartphone fell apart almost immediately and caused the company to push back its full roll out indefinitely, it's probably a good thing that Lenovo is waiting to launch the foldable PC until 2020.
Hopefully it'll be worth the wait.
