The video then goes on to show how to make an OLED as successive layers of materials. Indium tin oxide (ITO) on glass forms a transparent anode. That is then coated with PEDOT:PSS, a conductive ...

On top of this is a film of PEDOT:PPS, another polymer that serves to block electrons. The resulting yellow-green blob of an OLED actually works, and is at least as good as some of the other ...

Figure 1: Device structure of a P-OLED. In recent years, other industry players have announced new HIL materials. Dupont's HIL is a PEDOT-based material, where the polymer that the PEDOT combines ...
