Light-Emitting Polymer Displays
BlackSol writes "Yahoo is covering a very cool piece on the development of roll-up screens. Possible uses from home televisions, to tele-watches, and military uses such as real-time satalite fed maps in the field."
I wonder if these can get high enough res. to be useful for laptop/handheld displays? That would sure be handy...

It's not just the individual pixels which are made with polymers. It's the individual traces also. In fact, the whole field of polymer semiconducters is starting to ripen and bear fruit. The sheets of plastic they print won't only have light emitting portions, it can include power traces and even decoding logic! There might be a copper ribbon cable to connect the entire display to whatever external source provides data and power. But the entire display will be made from polymers.
This really is amazing technology. The circuitry is basically printed out using ink jet style heads. Actually, one of the article says that it actually plots the traces out ala a good old fasioned plotter as opposed to line-by-line like a printer. It's not hard to imagine that this stuff will lead to a rebirth of the homebrew electronics hobbyist. Even if you couldn't afford to buy your own plotter, a prototyping shop which owned one should be able to produce custom circuits to your own design in an extremely fast and cheap manner. Imagine a semi-conductor Kinkos! Could be cool stuff.
Actually the minimum is not x*y it's x+y(well 3x+y anyway, or better x+3y for rgb). If you imagine all other contions being set to high impedance. One pair at a time used to illuminate a pixel and a scanning techinque used. That only makes it 3328 connections.

Most of the posts here assume plastic = transparent. Yeah, that would be nice. But it's not necessarily the case here. Nothing in the article suggests that this display is transparent.
