Graphene-based touchscreen shown off on video

Thankfully, the same South Korean scientists who brought us 10 centimeter film never abandoned their post, and now Sungkyunkwan University has composited 30-inch sheets of the stuff and prototyped a working touchscreen panel as well. Using a modified version of the popular chemical vapor disposition (CVD) technique that grows the graphene on top of copper foil, they were able to produce a four-ply graphene stack with 90 percent transparency, plus resistance and durability reportedly superior to the dwindling indium supplies currently used in displays.
