Thank you Graphene.

 Samsung patented on using Graphene for making cheap,good,curved displays.The patent describes use of a network of nanostructures as the conductive layer of a touch screen. The nanostructures could include carbon nanotubes, nanowires, nanoparticles and/or graphene flakes. Graphene and other nanostructures are being studied as possible replacements for the costly indium tin oxide (ITO) in touch screens, which also has a disadvantage of being brittle, making it unsuitable for flexible touch screens. A network of graphene nanostructures provides an inexpensive alternative, which is also flexible and stretchable.And Graphene is proving to be trustworthy nano-structure.
