I think that kind of flexible circuitboard is what Plastic Logic is aiming for. Displays are just one application.

The two applications I can think of where a rollable display would make sense are the very small and the very large. If something needs to be small enough to fit into a pocket, but large enough to read, a rollable display might be helpful. On the other extreme, just as blueprints are rolled up presently, very large images are more convenient to deal with if they can be stored in a smaller footprint.

But for most mid-range applications, I agree, I'd rather have a thin, relatively rigid screen. The flexible display still might be less fragile, though, and I think that would be a good idea.
