These very low power screens will have a variety of uses in the market in the future. They can be update wirelessly and the first place you can expect to see them is in a supermarket near you. 

Dr Cliff Jones, Shaun Gray and Dr Emma Wood of ZBD Displays Ltd, winner of the 2012 Innovation Award, awarded by the Institute of Physics for developing and commercialising a novel e-paper display for use in shelf-edge labelling in supermarkets and other retail settings.

ZBD has created an e-paper display by applying a sub-micron texture onto the glass surface of a liquid crystal display, allowing it to hold an image even when the power is removed. 

The work is the product of world-leading research at the liquid crystal research centre at DERA.
