    摘要： The present invention is directed to methods for improving the performance of an electrophoretic display by modifying the display cell surface. More specifically, the methods are directed to modification of the microcup surface after the microcups are released from the mold. The microcups which have undergone any of the treatment methods of the invention show significant improvement in their surface properties, such as chemical functionality, surface roughness, surface tension, morphology, surface charge, surface reflectivity, surface conductivity and optical properties, particularly optical density in the visible light region. An electrophoretic display formed from the treated microcups has many advantages. For example, the display shows a higher contrast ratio, lower electro-optic response time, lower driving voltage, longer shelf life, higher imageincreasing bistability and higher threshold voltage. In addition, it exhibits an improved image quality by reducing undesirable scum formation or irreversible particle deposition on the microcup surface.

    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.
