At a meeting of the Canadian Association of Physicists in New Brunswick last month, physicists demonstrated an electronic version of paper and print that combines the optical principle used in reflective signs with a scheme for squelching the reflections at will. Although the team has not yet shown how to build a working display screen, researchers are enthusiastic that the technique could lead to displays with faster response times and lower power needs than other electronic ink schemes.
