I think the OP was taking issue with the flexibility, not the OLED. If the screen is to be flexible, this only becomes useful if everything else it's attached to is also flexible, in this case the glass protective screen, but actually also the electronic circuits it is to be attached to. If flexible screens can become mass produced so they are cheap enough to ship to consumers, then we may start to see some of the stuff that has been shown off as concept for years, e.g a fold up (http://static.ibnlive.in.com/pix/slideshow/01-2013/samsungs-shows-off/10-samsung-fexible-screen-youm.jpg) or roll up (http://static.ibnlive.in.com/pix/slideshow/01-2013/samsungs-shows-off/13-samsung-fexible-screen-youm.jpg) screen
Personally i see the fold up being realistic as it is essentially based on the clam shell that has been popular in the past, whereas the roll up screen would require the electronics be fit into a different, potentially smaller package as well has having the issue of supporting the screen while extended
