Colorful Displays from Graphene Balloons

Nov-08-16 Graphene balloons may one day open the door to more colorful e-ink displays.

Developed by a team of international researchers, the graphene balloon devices are made up of a double layer of two-atom thick graphene that has been placed on circular cavities etched into a sheet of silicon. Applying pressure to the graphene as it curves over the holes will create Newton rings, which causes a light wave interference that changes the color of the membrane.

According to the team, the graphene-based technology could improve display performance as well as lead to new kinds of flexible displays.
