Thus far, we've seen OLED rule the FDP International floor in Japan, but now we've got one more emerging display technology showing off its merits: e-ink. Soken Chemical & Engineering Company demonstrated a wall of 30- x 30-centimeter e-ink paper displays in order to showcase just what the technology was capable of. Quite honestly, we're still struggling to see just what that is. Practicality aside, it's still pretty fascinating to think that all of the colors you see above are being emitted from ultrathin displays, though the choice of pattern is questionable at best.
