Although displayed on a rather unimaginative, but a working prototype, the elastic OLED panel was unveiled as the Infinity Flex Display, and will hopefully bring some new designs to the smartphone market.

One thing that was pretty clear at the announcement is that we are looking at a 7.3-inch screen when unfolded, at least on the prototype.

The technology behind the flexible screen is quite impressive as it features a total of five layers, including cover window, shock-absorbent fil, ultra-thin polarizer, flexible layer, and the flexible backplane.

In addition to the flexible screen technology, Samsung also unveiled the new One UI, which is all about optimizations for upcoming foldable phones. Samsung has been working closely with Google to bring "seamless transitions" from a folded to the unfolded screen, as well as some multitask optimizations, allowing it to keep three apps open at the same time.

A big part of the presentation was also reserved for Samsung's Bixby platform, which will be getting many updates in the future, including support for third party app development, with the Bixby Developer Studio, as well as support for more languages, British, French, German, Italian, and Spanish.

Unfortunately, Samsung was not keen to talk about the launch of its first foldable Galaxy phone, but considering it had a working prototype, that one could not be far behind.
