We know that AUO is back into AMOLED production, with plans for a Gen 3.5 factory (which will go in line in 2011). AUO has a daughter company called Wellypower Optronics. Wellypower is Taiwan's number one CCFL maker (mostly used for AUO's LCD backlights) and is also a LED maker.
In a recent PR about a new fluorescent lamp, Wellypower says that they are also producing OLED lighting panels. I'm not sure if that's true, but perhaps the company does have an active OLED program.
