Plastic Logic and the CGC demonstrate the first graphene-based flexible display

In June 2013, Cambridge University's Graphene Centre (CGC) and Plastic Logic started to develop a transparent graphene-based backplane for flexible displays. Now Plastic Logic demonstrated the first display that was developed in that collaboration research. Plastic Logic says that this is the first time graphene has been used in a transistor-based flexible device.

The prototype (shown above) is an active-matrix electrophoretic (E Ink) display fabricated on flexible plastic. The electrodes are made from solution-processed graphene which was patterned after deposition with micron-scale features. The prototype has a pixel density of 150 PPI and was made at low temperatures (less than 100 degrees celsius). This is just a prototype of course and you can see many defects in display.

Plastic Logic says that the graphene backplane can also be used to drive LCD and OLED displays. In fact, the UK Technology Strategy Board recently gave a grant towards this research, with an aim to develop full-color OLED displays within the next 12 months.

This technology can also be adapted to enable flexible lightweight sensors, and they are already developing novel medical imaging and gesture recognition applications.
