This startup first caught the world's attention with the Que, a large screen ereader which was launched in the US market mere weeks before the iPad. For obvious reasons that device didn't go anywhere, and now it looks like PlasticLogic thinks they wouldn't be able to release any successful follow on devices, but they are open to the idea of potential partners using Plastic Logic's screen tech on new devices.
They're even going so far as to drop the PL 100, the academic ereader which was launched in Russia last fall. The PL 100 was released in time for a pilot program in Russian schools, but it won't be getting a wide distribution in Russian schools. I'e been told that the current model will still be supported, but I wasn't told that it will stay in production.
Instead PlasticLogic is going to look for industrial and commercial uses for their flexible screen tech. There are any number of situations where a flexible, durable, and low power display would be worth the extra cost.
Unfortunately for Plastic Logic, E-ink beat them to it. As you can see from this booth visit video from FPD 2011, E-ink's screen tech is used on all sorts of devices including several that would strike you as unlikely.
So what does that leave for Plastic Logic? Not sure, but there is always the chance that they could license their work to other manufacturers to use rather than use it themselves. PlasticLogic is a leading researcher in plastic based transistors, and I'm sure they will find any number of uses for that technology.
