Looking at this, my first idea for the future use of this tech would be in mobile devices.
Over the years smart phones have became unwieldy huge due to the consumers needing a bigger screen for all their gaming/movie watching/net surfing/etc. needs. This often leads to transportation problems, easy breaking due to the large glass surface area (try breaking my old-school brick-phone just by sitting on it) and them just looking bloody ridiculous when you raise them to your head to actually use them as a phone.
Now imagine if this tech could be used to create thin, rolled-up screens that could be retracted into a tube on the phone. With this you could have the best of both worlds: a relatively small device that you could easily put into your pockets, and when you actually need to use it you could just open up the tube, roll out a large screen and poke away at it at your own merriment.
