During a lecture at Lighting Japan last week, Philips’ OLED head of production Wolfgang Doetter gave some insights on Philips OLED production and the general OLED lighting market of the near future. The conclusions from Wolfgang's lecture is that the OLED market is evolving rapidly and that process knowhow is the key to producing high quality OLED panels.
Wolfgang said during his speech that for producing reliable OLEDs one needs to master the processes and needs to be able to replicate them on a regular basis. Issues like on-plate layer thickness uniformity as well as plate-to-plate thickness uniformity or the ability to produce OLEDs to a defined color point are basically the issues any producer of OLEDs has to master in order to be able to maximize the production yield and reliably deliver high quality OLEDs.
