High Contrast Piezo-Electrophoretic Displays and Methods of Making the Same

Abstract: low voltage piezo-electrophoretic displays including low profile piezo-electrophoretic displays. in some embodiments, the piezoelectric material of the piezo-electrophoretic films can be selectively patterned with an insulating material during fabrication. in some embodiments, the piezoelectric material of the piezo-electrophoretic films can be selectively patterned with cuts, or partially-coated with a conductive material on a surface opposite to the electrode. such films have high contrast ratio and are useful as security markers, authentication films, or sensors. the films are generally flexible. some films are less than 100 �m in thickness. some films are less than 50 �m in thickness. displays formed from the films do not require an external power source.
