Researchers from Korea's KAIST institute developed a rollable OLED device that uses graphene-based electrodes. The researchers say that the new OLED is much more durable when bent compared to current devices made with ITO electrodes.

The electrodes were made from a stack of materials - titanium oxides, graphene and conductive polymers. The new OLEDs were also brighter than current devices, and with a higher color gamut. This was achieved by maximizing the resonance within the OLED.

ITO do not fix on plastic substrate

I have heard Chemical professor James Tour at Rice University in Houston say on a video on youtube that ITO do not fix on organic substrate(plastic is organic substrate).

So graphene or molybdenum disulfide or polymers are the organic materials which must be used for TFT transistors on Amoleds on plastic foilthin substrates.
