Patent drawing for a Samsung device with a 3-sided flexible display go as far back as April but now a parts supplier for Samsung reports that the unique screen has entered production.

This sounds like a good time to start making these if they'll end up on the Galaxy Note 4, which is to be unveiled in a month. However, the screen is reportedly built on a plastic substrate that's difficult to work with and only limited numbers will be available at first.

And the new Galaxy Note will be anything but a low-volume device. There were rumors that the Note 4 will be available in two versions one with a conventional flat screen and one with either a curved screen or a three-sided screen.
