I have seen images somewhere of a watch with a tv using the Light Emitting Polymer, I can't seem to find it anymore.
When I first had a look at the site they claimed that they were working with Epson, and that a slightly modded InkJet printer was sufficient to print a screen.
They have been working to try and improve the color range available. I think it would be pretty neat if you could just roll up a screen and take it anywhere.
