Finally, a tablet that folds up into a phone that fits in your pocket

Lenovo is back at blowing minds again with another concept device with a bendable screen.

At the third annual Lenovo Tech World last week, the Chinese tech giant wowed attendees with the Lenovo Folio, a tablet with a screen that folds in half into a phone.

Before you start getting too excited, you should know that the Folio is a concept device, which means it may not be released as a consumer product anytime soon. Even so, that doesn't make the device any less impressive.

The tablet has a 7.8-inch screen with 1,920 x 1,440 resolution, a Qualcomm Snapdragon 800 processor, and runs Android 7.0 Nougat. It's not exactly peak performance in 2017, but that's not why'd you want this thing -- you'd want it for the bendable screen.

When folded, the tablet shrinks down into a 5.5-inch phone that could fit into your pocket. As you can see in the demo videos above and below, the display folds neatly in half with pixels filling all the space where a hinge would normally. The UI automatically adjusts to work as if there are two displays. It's pretty bananas!

As futuristic as the Folio is, Lenovo isn't the only company working on a tablets that fold up into phones. Samsung and Oppo have been developing the same exact thing for years.

Samsung's rumored foldable tablet-phone, codenamed "Galaxy X," was reportedly scheduled for launch by the end of this year, but production issues have supposedly pushed a commercial launch back until 2019.

The great tablet gold rush may be over with people opting for larger phones instead, but that doesn't mean they can't make a come back. A tablet that folds into a phone (or if you prefer, a phone that folds open into a tablet) could be just the thing to reinvigorate interest in slowing product category.
