    摘要: The present invention relates to novel patterned embossing and patterned filling methods. Both methods are simple, reliable and cost effective ways for manufacturing the segment of signage electrophoretic displays. The displays prepared by the present invention requires only one patterned electrode layer. The undesired visible line traces are eliminated and the manufacture of the present displays does not involve the costly precision registration step used in the previously known assembly processes dealing with two patterned electrodes. Moreover, the electrophoretic fluid is present only in the patterned and switchable area of the display. This not only significantly reduces the material cost, but also improves the overall display quality by reducing defects and non-uniformity.

    摘要: A process for forming a patterned thin film structure on a substrate is disclosed. A pattern is printed with a material, such as a masking coating or an ink, on the substrate, the pattern being such that, in one embodiment, the desired thin film structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structures.
