    Five years may be a bit optimistic. I was already investigating printable electronics as a VC at Sony 12 years ago, when they were beginning to move from university to start-up stage. Their path to commercialization has been very slow. In fact, very few of the materials-based technologies I was looking at from that era have attained applications in consumer electronics, though a couple of the companies have survived. One of those is E-Ink, whose paperless display is used in Kindles — but 10+ years later, that company still isn’t selling technology meeting the performance spec we were hoping for: full-motion color display without filters. Maybe it just isn’t targeting that market anymore, since LCD is so cheap and good for that app. (OLED is another LCD rival that Sony, Samsung and others have spent tremendous effort on, for an even longer time, though products remain few and low-volume.) The D in R&D takes a lot of time, trial and error, and in the meantime the cost-performance stats of competing technologies improve. At least: when it comes to manufacturing real stuff, not software.

    Clarification: LCD remains tops for full-motion display applications, but it uses color filters, too (unlike OLED and a couple of others).
