id=\"Wonder_material_graphene_improves_touch_displays\"><\/span>Wonder material graphene improves touch displays<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The secret behind the new displays is a combination of graphene and silver nanowires.\u00a0Normal smartphone displays get their touch functionality through a layer of indium tin oxide.\u00a0This layer is particularly transparent and has high electrical conductivity, but the material is relatively rare, expensive and delicate.\u00a0From time to silver is used as an alternative, which is not exactly cheap.<\/p>\n<div class=\"code-block code-block-2\"><\/div>\n<p>The team from Sussex found that the amount of silver needed can be drastically reduced if the material is combined with graphene.\u00a0To make the screen, the researchers float a layer of graphene on the surface of water, pick it up with a rubber stamp, and press it onto a layer of silver nanowires.\u00a0The technology sounds complicated, but according to the researchers, it can be scaled up well for industrial production.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Cheap_flexible_displays_could_be_the_future_of_smartphones\"><\/span>Cheap flexible displays could be the future of smartphones<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><em>&#8220;The addition of graphene to the silver nanowire network thus increasing its ability to conduct electricity by a factor of ten thousand.\u00a0The same, or better, performance.\u00a0As a result screens wants to be more responsive and use less power, &#8220;<\/em>\u00a0said Alan Dalton, who heads the team.<\/p>\n<p>The\u00a0use of graphene gives\u00a0rise to other advantages than merely reducing the costs of producing the touch displays.\u00a0The resulting layer can be bent as often as desired without changing the electrical properties.\u00a0One day, such completely flexible displays could be developed that are extremely accurate in processing touch signals.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sooner or later, every smartphone owner has to deal with a broken or cracked display.\u00a0No matter how well you take care of your
