Mitsubishi Chemical and Pioneer announced that they managed to fabricate a white OLED in which the emissive layer was formed in a coating process (not sure if they mean spin-coating or printing). The OLED is efficient (52 lm/W) and the lifetime (LT50) is 20,000 hours (at 1,000cd/m2 luminance). The upper layers in this OLED are made using vapor-deposition method. The companies plan to commercialize printed OLEDs at around 2014.

Mitsubishi's Velve panels (which will start shipping soon) use a coating process only for the foundation layer and not the emissive layer. In September 2009 we interviewed Verbatim's OLED team (which will market Mitsubishi's OLED panels).
