Plastic Logic explains why OTFTs are compelling as flexible OLED backplanes

A few weeks ago I posted about Plastic Logic's OTFT-based AMOLED demonstration. While the company's current demo is a simple display (monochrome white), it seems that Plastic Logic believes that OTFT technology is now reaching a performance level for adoption in AMOLED displays.

I discussed this with Mike Banach, Plastic Logic's Research Director. Mike (and the rest of the team at PL too, of course) says that organic semiconducting materials have reached a "tipping point" in electrical performance that makes them viable to drive flexible OLED displays. Couple this with the industrial and flexibility benefits of using solution-based organic materials makes it a compelling technology option for display makers looking to establish a position in the flexible display market.

OTFT are very promising as flexible OLED backplanes because they are processed at low temperatures (below 100 degrees Celsius) and they are more flexible compared to silicon or oxide-TFT backplanes. Traditionally OTFT materials suffered from low mobility which meant they couldn't' be used for OLED displays. But performance has been improving constantly in past years.
