Lenovo usually brings the heat to MWC with a conversation-starting concept. Last year, it was the transparent display laptop, and this year (if the leaks are true), it will be a dual-hinge foldable and stacks two regular displays on top of each other to form one mega vertical panel.

This "foldable PC" is near-unique and gives you a massively vibrant display to boost your creativity, but question marks over its performance remain

This summer Lenovo plans to launch the world’s first laptop with a rollable OLED display that extends upward to give you 50 percent more screen space when you need it. But the company may have another laptop on the way that lets you double your screen space when you want the power of an extra display.
