Graphene could replace ITO in OLED displays

In a new UK-funded research, scientists from Paragraf and Queen Mary University of London have successfully fabricated an Organic Light-Emitting Diode (OLED) with a monolayer graphene anode instead of the problematic ITO.

Professor Colin Humphreys of Queen Mary and Paragraf, says: “Because of its importance and scarcity there have been many attempts to replace ITO, but no material has been found to have a comparable performance in an electronic or optical device until now. Our paper is the first paper in the world to demonstrate that graphene can replace ITO in an electronic/optical device. We have shown that a graphene-OLED has identical performance to an ITO-OLED. ITO-OLEDs are widely used as the touch screens on our mobile phones.”

GS Alliance develops a graphene QD and silica composite to create efficient white LEDs

Japan-based material developer Green Science Alliance developed a new composite material made from a combination of graphene quantum dots and silica, which could be useful for creating white LEDs from blue LEDs (440-470 nm).

Green Science Alliance graphene QD + silica composite for white LED

The company says that this is the first adoption of such a material for LED applications. The company says the adoption of the QD and Silica offers superior performance to the currently-used phosphor as the QDs do not suffer from light scattering, and the white LED is more efficient. The material is also said to be inexpensive.
