Pentacene TFTS were certainly worse than A-Si:H (maybe they are better now) but they were good enough for x-ray panel use. <br /><br />The real advantage is that the polymer processing is low-temperature and could be set up to operate roll-to-roll so that all the circuitry can be done on flexible plastic. This would solve some huge problems in x-ray inspection of aircraft structures because the detectors could be made to conform to wing surfaces or rolled up and passed through access holes like film. In medical use, all portable x-ray coudl become digital because the risk of breaking the glass panels used now goes away.Dave Gilblomhttp://www.alt-vision.comnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-31789155089910884752011-11-06T18:26:18.151+02:002011-11-06T18:26:18.151+02:00How compare this technology to TFT based one?How compare this technology to TFT based one?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-11657299206573623622011-11-06T13:58:07.811+02:002011-11-06T13:58:07.811+02:00When I worked at Varian back in the late 90's,...When I worked at Varian back in the late 90's, I visited Uniax to discuss making polymer photodiode panels on plastic substrates for use in portable x-ray imaging. They had already solved the electrical contact problem and demonstrated a line scan imager made of polymer photodiodes on glass. Somewhere in my archives I have a color image made with that scanner. It appeared that what we needed was entirely feasible. The transistors from Penn State would have been good enough for the active pixels needed in x-ray panels. <br /><br />However, while the discussions were going on, Dupont bought Uniax and discontinued the sensor work. Fifteen-plus years later, here we are again. Maybe the French are serious about commercializing this technology.Dave Gilblomhttp://www.alt-vision.comnoreply@blogger.com
