Graphene Back in Flexible-Display News

A new technique to manufacture graphene could lead to a new era for electronic displays, according to a report published by a team of researchers from the University of Glasgow. Graphene is a thin layer of carbon that is more than 200 times stronger than steel, conducts heat and electricity, and is nearly transparent.

By using the ultrasmooth copper foils found in lithium-ion batteries, researchers were able to drive down production costs from $115 per square meter to $1. Devices using the graphene sheets performed better in tests.

“Large-scale and low-cost synthesis of high-quality graphene films and the compatibility of our method to the roll-to-roll fabrication would open an avenue through the realization of graphene-based flexible optoelectronic systems such as cellphones with roll-up displays, e-paper, radio-frequency identification (RFID) tags, as well as medical patches that can be attached to the skin,” the researchers wrote in their report.

Graphene has been touted as the material that would become the e-reader display of the future before. The difference this time is the focus on display applications and the cost of the process, according to a report in TeleRead.
