The first time I saw a  flexible display at CES, I was awed.  I couldn't imagaine what could come next. 

I'm curious to see the thin-film transistors when they're ready.  Thanks for the article.

Nadine, I admit that I have a tough time believing flexible displays can work. They seem so counterintuitive, yet there are several development efforts going on to produce them.

It's going to be interesting to see what applications come from this. The flexible displays I've seen are fun, but I haven't seen them in a setting where flexibility was a necessity rather than a nice gimmick. Yet I'm sure somebody will come up with a great idea once this technology is available.

I'm sure that engineers will find many applications for thin film batteries and displays. I can remember when people claimed the only application for PCs was to store recipes. We've found some new apps since then.

I agree, Rob. I have a feeling a few years from now they will be in the technology domain in products that we don't even give a second thought to as being out of the ordinary...kind of like the evolution of LED flashlights.

One idea did come to me while reading through the comments.   I can see this used for tablets aimed at the kid's market.  I never imagined that a $400 item could be popular for children.  If you've ever watched two toddlers arguing over an ipad, you know what I mean.

Good point, Chuck. We're likely to be surprised by what shows up now that this flexible technology is becoming available. It didn't take long for applications to show up for the PC. Smart phones are another good example. Using the phone to make a call almost seems an afterthought for young users.

I agree, Nadine. Tiny kids take to tablets in a remarkable way. In a family, the kids take over the tablets in ways they never tried to do with desktops or laptops. Flexible computers will be perfect for kid applications.

Plastic Batteries

I can remember reading about two potential plastic battery technologies more than a decade ago.  I'm not talking about using plastic as an armature.  There were two developments; one was more like a cap for charge storage; the other was like an organic plastic.  I can also remember about film batteries which was more like plastic armature with the media deposited on the plastic film.

Yes, Chuck, just a few apps since then :) For flexible displays, the apps I see mentioned most often are watches and other wearable computers, medical devices, and signage. I think Nancy's right: once the tech is available, they will be all over the place and we'll wonder how we ever did without them.

At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
GE Aviation not only plans to use 3D printing to mass-produce metal parts for its LEAP jet engine, but it's also developing a separate technology for 3D-printing metal parts used in its other engines.
The demand for solar energy around the world will grow a total of 75% by 2019, according to a new report by Lux Research. Trade disputes and policy changes, though, will complicate the picture.
Bayer MaterialScience is using CO2 to produce a precursor for high-quality polyurethane foam at its pilot plant in Leverkusen. The transition to full-scale manufacturing is expected in 2016.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
