That graphic of the screen rolled around the person's wrist would be cool upgrade for football quarterbacks- would allow for more complex game plans since the coordinators could display whatever they want on the screen in real time during the game.

Of course there are probably more important applications of this technology too.

I'm not sure whether this would be allowed. In soccer, for example, using earphones and so on was forbid based on the rule that it wasn't part of the allowed equipment.

I believe creaghpatr was talking about American Football. The coaches already use radios which have speakers inside the quarterback's helmet to relay the plays to them. It seems like this would be a logical jump as they could get more information and crowd noise would not be a factor.

:) yes, I thought so, that's why I used soccer to make the distinction... but I didn't knew football allowed such intense communication during the game, and it would be funny to see a quarterback trying to read his pulse while he's being tackled.

Thought the same thing immediately -- but then again, why not just have a thing that flashes a few LED lines with text; no need for bendy tech.

My second reaction -- if i'm reading it right -- the solution was to remove inflexible glass, and replace it with flexible plastic?! What took so long? (i'm sure there's some cool technical challenges here, but this was one of those articles where i was expecting really cool solution, but instead got... "duh, plastic")

"The plastic substrates are poor gas-barriers for oxygen and water vapor, and the OLED materials can seriously be damaged by their gasses. "

Incidentally, polymer stabilized cholesteric liquid crystals make an excellent passivation layer and are highly flexible thinfilms. I've always wondered why flexible OLEDs (FOLEDs) never adopted. Maybe HN knows?

Is my long-dreamed-of, papyrus scroll -> cellphone screen scroll, full-circle-moment finally at hand?
