Samsung's Galaxy S7 and Galaxy S6 both come with "edge" editions that flaunt curved displays and attractive screens, however the curve isn't really an all-important trait in smartphones.

Samsung has stirred conversations in the past by teasing fans with foldable smartphones and tablets, but if rumors doing rounds are anything to go by, the South-Korean tech firm is prepping to launch a different type of foldable display.

A Galaxy X flagship flaunting a flexible display will reportedly verge on the Galaxy Note and Galaxy S line in 2017. The popular South-Korean smartphone maker is flaunting a prototype display that would enable a handset to be rolled up, Yahoo reported.

Apparently, the technology already exists, and Samsung took the wraps off a rollable OLED screen at the SID 2016 event in San Francisco.

The rollable OLED measures 5.7-inches when it's rolled up, but easily fits into a 35mm film canister. In addition, it offers Full HD resolution i.e. 1920 x 1080 pixels, according to reports on Slashgear, which also captured the video showing the technology. Check it out below:

Without the touch layer on top, the featherweight (5g) foldable OLED screen is just 0.3mm thick. The technology, without question is impressive and could help Samsung and other smartphone makers to introduce new form factors to the smartphone space, compact devices that can be converted into small tablets or phablets simply by employing a foldable screen.

Samsung will lock horns with LG - both preeminent makers of flexible displays. The technology will probably be used first in smartphones and wearables, followed later by automotive displays and tablets.

According to Guillaume Chansin, senior technology analyst with research firm IDTechEx, foldable displays will enable users to carry large display in a modest portable device.

LG, which is also working on foldable screens, trotted out an impressive 18-inch flexible OLED display during the CES 2016 event held in Las Vegas in January.

If existing reports proved true, Samsung's foldable device will actually fold in half - like a wallet.

Until Samsung confirms the rumors, we suggest fans take this with a grain of salt.
