Beschreibung
Zusammenfassung:	The invention relates to a low-profile piezo-electrophoretic film and a display film including the same. In some embodiments, the piezoelectric material of the piezo-electrophoretic film may be patterned with a high voltage electric field after fabrication of the piezo-electrophoretic film. Such films may be used as security markers, authentication films or sensors. The films are typically flexible. Some of the films have a thickness less than 100 [mu] m. A display formed from the film does not require an external power source. 低轮廓压电电泳膜和包括低轮廓压电电泳膜的显示膜。在一些实施方案中，压电电泳膜的压电材料可以在压电电泳膜的制造之后用高压电场图案化。这种膜可用作安全标记、认证膜或传感器。膜通常是挠性的。一些膜的厚度小于100μm。由所述膜形成的显示器不需要外部电源。
