The other day, Weibo user, @包子玩机, said that Xiaomi’s next generation device will sport a 2.5D display screen. Not long ago, analyst Bo Jiutang revealed that Xiaomi was planning to release two high-end phones at the end of the year or early next year. We can guess that both of these phones will sport a 2.5D curved display screen.
Right now, the Apple iPhone 6, Samsung Note 4, and most of Nokia’s Lumia series use 2.5D curved screens. The Chinese cellphone, IUNI U3, also has one. [source]
