In our Touchscreen Blog we have already reported several times about graphene. It is one of the hardest and most resilient materials in the world and at the same time is very flexible, transparent and relatively light. There are various research projects around the world that specialize in graphene as a replacement for ITO (indium tin oxide), which is currently still frequently used in flat screens, touchscreen monitors and mobile phones.
Prototype of a flexible graphene display
One of these graphene research stations is the Campridge Graphene Centre (CGC) at the University of Cambridge. Together with Plastic Logic Ltd., also based in England, the university announced in a statement at the end of 2014 that it had succeeded in producing a flexible graphene display for the prototype of a transistor-based, flexible device in cooperation with Plastic Logic.
The aforementioned prototype is said to have been created in a similar way to screens found in eBook readers. With the exception that this is flexible plastic instead of glass.
Presentation of the Graphene prototype
The new 150 ppi backplane used was created at low temperatures (below 100° C) using Plastic Logic's so-called Organic thin-film transistor technology (OTFT). The graphene electrode was deposited from the solution and then micrometer-scale functions were structured to complete the back panel.
If you would like to learn more about the manufacturing process of the prototype, more information is available on the website of the Campridge Graphene Centre.
