well, technically they are already generating revenue with pixel precision. unfortunately, it's not much.
i think more improvements need to be done to the display before it can be commercialized. but, we really have not received an update on where the technology stands in quite some time other than bits and pieces that were issued in various research papers published last year. the progress they had made even then was a surprise so i am quite eager to hear where things stand now.
more than generating revenue, i think the initial game changer for the shareholders will be if a larger company (such as Boeing) signs on. i think this needs to happen fairly soon or the PPS will fall back to the lows of last year. if a larger company signs on, it will help finance the R&D and commercialization and also will give new credence to the work being done.
