Lenovo's Rollable Concept Screen Seems Almost Like Magic

This laptop's screen grows taller with the double-tap of a button.

Motorola has already impressed us with its rollable concept phone at this week's Mobile World Congress in Barcelona, but parent company Lenovo is getting in on flexible displays too with its mind-boggling concept laptop featuring a screen that grows taller at the double-tap of a button. 

Having seen it in person, it's almost like magic.

Seen on its stand at the mobile trade show, the concept device appears mostly as a regular laptop with a keyboard, trackpad and 12.7-inch display. That display is flexible, however, and actually slides in and out of the body of the laptop. A double-tap of a button on the side and the full length of the screen begins to slowly work its way out, resulting in a much larger 15.3-inch display with an 8:9 aspect ratio.

This tall screen format could be great for working professionals because it offers a lot more real estate for scrolling down web pages or for working on large documents or spreadsheets. 

It's similar in principle to the tech used in Motorola's rolling concept phone, which also features an extendable screen that provides a larger surface for watching 16:9 videos. Like the phone, Lenovo's laptop is purely a proof of concept and there are no plans to put it into production or even to use the technology on future devices.

However, with clearly a lot of time, effort and money gone into the development of this laptop, it wouldn't come as a surprise if we see this tech in some form on sale a few product generations down the line.
