Digitimes reports that AUO has started to develop a printing process to make OLED panels, with hopes that this new process will lower the production cost and increase the material utilization. AUO is suffering from low (50%) yields in its current production process - which uses vapor deposition. The report suggests that AUO is also developing Oxide-TFT backplanes for OLEDs - but this isn't news - AUO unveiled an Oxide-TFT based 32" OLED TV prototype back in November 2011.

Actually all OLED makers are looking into more efficient production processes based on printing so this is hardly a surprise. It's likely that it will take some years before we'll start seeing printed OLED panels on the market though.
