Abstract
To obtain truly flexible electro-optic films for image display or other related applications and to obtain a low cost solution for making electro-optic films, a new concept for manufacturing such films is disclosed. The method disclosed in this invention include mixing liquid crystal with “sponge particles” having fibril or porous surface morphology, coating such mixture directly on substrates with conductive electrodes and laminating with release liner or another substrate having conductive electrodes. The electro-optic films manufactured by using traditional R2R coating techniques. The electro-optic film manufactured by the method disclosed in the invention can be used for segment type, passive matrix type or active matrix type display applications or other related applications.
