Super Hi-Vision, the hopeful 7,680 x 4,320 successor to HD, NHK also dabbles in small, flexible OLED panels. The Japanese public broadcaster recently showed off a 5-inch prototype display that, while bearing a heavy green tint and very noticeable rows of dead pixels, was still a significant improvement over a similar screen it demoed in 2009. Sure, it's not quite as flexible or vibrant as Sony's rollable OLED from last year, but it does seem to suffer from fewer bad pixels -- an important step towards maturation. Don't miss the video after the break which offers some pretty nifty glimpses at a number of bendable OLEDs. It's clear the tech is still a little wet behind the ears, but we're definitely getting closer to a future populated with TVs that roll up for storage and e-readers that fold like a paperback.
