If nothing else, Royole grabbed our attention a couple of years back by bringing the first foldable smartphone to market. There’s something to be said for being first, I suppose. It raised the profile of a largely unknown name in amongst the tech press, even if it didn’t exactly kickstart a form-factor revolution. Among other things, the FlexPai seemed firmly stuck in the prototype stage, to be perfectly honest.

RoTree, manufactured by Royole, consists of 500 units of fully flexible screens. As light and thin as real tree leaves, RoTree offers more than that – people can change images or videos on the leaves! The tree is "planted" at Shenzhen Bao'An Int'l Airport as new airport landmark! pic.twitter.com/8J7HNH9ONF
