Phones, computers with OLED displays may get cheaper with Graphene use, says new study

A new research has found a viable replacement for Indium, a rare material used in the making of OLED panels. If brought to wide-scale use, the technology based on Graphene could drastically bring down the cost of OLED manufacturing.

As smartphone makers rush to introduce OLED screens on their phones, one key ingredient in the panel's making might be keeping its price up. In new research, scientists have found the wonder material Graphene to be a viable replacement for it, which can eventually bring down the cost of OLEDs.

Researchers from Paragraf and the Queen Mary University of London have come up with a new study that demonstrates the development of an OLED with Graphene. In doing so, the scientists were able to replace Indium, one of the rare metals used in the making of OLED panels.
