Samsung showed of a massively awesome flexible OLED screen at this year’s FPD 2008. Unfortunately, I don’t have any specs to go on and it’s difficult to tell how large the screen is, but I think the embedded video says enough. Here’s looking at a huge ass phone screen in ’09.
It’s worth noting that the ‘flexing’ intervals are pretty few and far between, which leads me to believe the technology isn’t totally sound. In other words, fold the screen 5 times in 30 seconds and perhaps it would have problems.
