Researchers from the UK's Queen Mary University of London together with scientists from graphene develop Paragraf have successfully fabricated a flexible OLED device with a monolayer graphene anode instead of the usually-used ITO anode.
The researchers say that this is the first time such a device was demonstrated. It was shown that the graphene-OLED has identical performance to an ITO-OLED. The researchers used high-quality monolayer graphene directly deposited on a transparent substrate using a commercially available MOCVD system.
All the processes used in the fabrication of the graphene-based OLED can be performed at wafer scale. This paper demonstrates the potential for graphene to replace ITO as anodes in OLED devices in a technologically and commercially effective manner.
