An iterferometric modulator is formed having a dielectric with charge persistence. The interferometric modulator is addressed by a method making advantageous use of the charge persistence property, wherein the interferometric modulator is pre-charged in such a way that the pre-charging is not observable...http://www.google.com.au/patents/US20070041079?utm_source=gb-gplus-sharePatent US20070041079 - Interferometric modulators having charge persistence
