The Lenovo ThinkBook 'Codename Flip' AI PC Concept can be set to five different display modes, thanks to its flexible OLED panel. But who is this thing for?

Lenovo brought concept laptops with 3D screens, foldable OLED, and solar panels to Mobile World Congress, along with new ideas for 3D gestures and AI accessories.

Lenovo has a history of showing off weird and interesting new product ideas at trade shows. Remember the laptop with the rollable display from a few years ago? This year at MWC it's doing the same thing, with a host of unique, fun, and downright silly ideas, some of which could inform designs and decisions for future products.
