Yet another variation on the recent trend in foldable phones is a smartphone that bends into a smartwatch.
The concept is one of five flexible display devices under development at Chinese vendor, TCL, which makes cheap televisions, but also makes phones under its BlackBerry and Alcatel brands.
According to documents obtained by ZDNet sister site CNET, TCL is working on two tablets, two smartphones, and a phone that wraps around the wrist to become a smartwatch.
The flexible phone-watch concept is detailed in a patent that shows a long phone with a display that curves backwards to wrap around a wrist. It's not unlike some of Apple's patents for a wraparound watch in the months before it released the first Apple Watch.
TCL's other foldables include a tablet with a display that folds inwards and one with a display that folds outwards. The two smartphones in the works similarly fold inwards and outwards.
News of TCL's foldable plans come as Samsung prepares to take the wraps of its first foldable, rumored to be called the Galaxy X. It's expected to reveal the device alongside the Galaxy S10, just ahead of Mobile World Congress later this month.

Samsung gave the world a peek at its foldable prototype in November, revealing a 4.5-inch screen that unfolded into a 7.3-inch tablet. Samsung plans to produce one million foldable phones this year using its Infinity Flex technology.
Apple also has eye on the foldable market, recently updating an old patent from 2011 for a phone that folds in half for easier carrying.
While more foldable phones and tablets are expected to launch this year, at the moment the only one that can be bought is Royale's FlexPai, but it costs well over $1,000 for the entry-level unit. Samsung's foldable is also rumored to be very expensive, costing around $2,000.
