Lenovo has another funky experiment it’s announcing at Mobile World Congress: the ThinkBook “codename Flip” AI PC Concept. It’s a productivity / business laptop with a flexible display, allowing it to be used as a traditional 13.1-inch clamshell, a folded-up 12.9-inch tablet, or a laptop with an extra-tall 18.1-inch vertical screen.

Lenovo introduced the ThinkBook Flip AI PC Concept at the Mobile World Congress, a unique productivity laptop featuring a flexible OLED display. This innovative design allows it to function in multiple modes: as a traditional 13.

Fitting an 18-inch display into a 13-inch laptop body the way Lenovo has done for its ThinkBook Flip is clever, as it's a great way to get more screen real estate in a compact design — bar getting a portable monitor.
