Winstar, a leading PMOLED producer from Taiwan, hosted a seminar in June 2014, and they gave two OLED lectures - describing their OLED products in the present and the future development expected from Winstar.
There's some interesting details in there. First of all, while Winstar is currently producing glass-based PMOLEDs, the company is also developing flexible PMOLED panels. One of the major challenges is encapsulation and Winstar is using ALD technology for this at the moment, developed in collaboration with ITRI.
Winstar updates us on its OLED lighting development. Winstar goal is to produce low-cost flexible panels using a coating process.
Winstar also revealed that the company currently uses red phosphorescent materials and white, yellow and green fluorescent ones. In Q4 2014 they plan to switch to green and yellow phosphorescent mateirals (to increase the power efficiency). White phosphorescent materials are expected in Q2 2015. Eventually, Winstar hopes to switch to TADF OLEDs emitters.
