Samsung rumors that there will be a new mobile device with bent display grow day by day. The first candidate it seems to be the Galaxy Note 4. Samsung demoed last year the YOUM three-sided display technology, so this will probably be the technology in the new device.
Samsung will try to test the market first, with just one million units, claim the analysts and will be brought for a niche audience, as this new technology need a time to be known by the customers. The first bent mobile device from Samsung, Galaxy Round, didn't make such a good impression in the market and it didn't sell very well. So, this could be a good strategy for Samsung to test the waters firstly.
Last year, Samsung executives said that this year the investments in flexible OLEDs around 1.9 billion $, which is a significant investment. They also said that this year will launch a bendable screen, with a full featured device coming in early 2015. The biggest concern for Samsung is that the battery segment is still behind the other hardware technology development. They must invest a lot in this segment to make more developments.
