Piezo-electrophoretic films and displays, and methods for manufacturing the same

Abstract

Abstract Low voltage piezo-electrophoretic films and display films including low profile piezo-electrophoretic films and displays. In some embodiments, the piezoelectric material of the piezo-electrophoretic films can be selectively patterned with high-voltage electric fields during or after fabrication of the piezo-electrophoretic films. 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 µm in thickness. Some films are less than 50 µm in thickness. Displays formed from the films do not require an external power source.
