Dutch website Let's Go Digital has uncovered a Samsung patent that details a wraparound mobile phone display. Unlike the company's folding phone, this recently approved patent shows a flexible display that wraps from the front of the phone up over the top and down partially across the back. Among other uses, the rear display could be used to provide an image preview to the photo's subjects.

The patent describes multiple potential uses for the rear display, including as a camera preview. A translation of the section describing this potential use reads:

For example, at operation 1620, the electronic device may confirm to the user that he wants to selfie. When the self-portrait mode is selected, the control unit of the electronic device can activate the rear display provided in the same direction as the direction in which the camera is mounted. The preview image generated in operation 1660 may be displayed through the activated rear display.

Who needs a high-resolution front-facing camera when a secondary display can turn the main camera unit into a selfie cam?

Though the idea of a dual-display smartphone isn't new, Samsung's method — using a flexible OLED panel for a seamless wraparound screen — is unique. Of note, this arrangement could enable users to capture selfies using the device's superior rear camera in lieu of the front-facing camera.

As with any patent, it's possible Samsung may never bring a device featuring this technology to market.
