At this year's Tech World, Lenovo showcase new prototypes with some wild designs. Considering these are just concepts, we may never see them on the shelves, but there is also a high chance some of them will enter the mass production as the technology matures.

The Lenovo Cplus concept phone features a very flexible design, even more flexible than the LG G Flex. It packs a 4.35-inch AMOLED screen and a real leather back. The goal of such phone is to wear it like a bracelet when you're not using it.

Lenovo Folio is a phone/tablet concept that also has flexible display and is definitely one of the most interesting concepts. The display expands from 5.5 to 7.8 inches and it runs a Qualcomm Xiao Long 800 processor with a 1920 x 1440 display resolution.

The next is CAVA, a digital assistant that uses facial recognition and natural language processing.

The company also showed its AR device called daystAR. It is a standalone headset that offers a 40° field of view with no need for a PC or a phone.

As we said, some of these devices will probably be announced in the future, but Lenovo has yet to do a lot of R&D before they are ready for mass production.
