Sony has a paper-thin display that is bendable, crumpleable and still work. See a demonstration of the paper-thin display on CBS2Chicago and see more about it in the article "Sony Demonstrates Paper-Thin Flexible Video Display".

Tectonic comments on the new digital display:

The concept of flexible digital displays is not exactly new but working flexible displays are few and far between. Now it seem Sony has made something of a breakthrough with a working, razor-thin display that bends while simultaneously displaying full-colour video.

There are some limitations to the concept at present. It seems that making the display bigger is a problem. Making the display pliable is easy in smaller units but when creating anything more than a couple of inches the pliability suffers.

Still a 2 inch display could be quite useful say on supermarket shelving to show the name and price of the items on the shelf. Perhaps this could be built into a wireless unit that is networked to the supermarket's central server in the store.

The paper-thin nature possibly would lend itself to be snapped into a card holder at each item's shelf location. Interesting to see where this concept goes from here. Sony are saying that they have not figured out an application for this product so far.
