    摘要： This invention relates to an electrophoretic display or a liquid crystal display and novel processes for its manufacture. The electrophoretic display (EPD) of the present invention comprises microcups of well-defined shape, size and aspect ratio and the microcups are filled with charged pigment particles dispersed in an optically contrasting dielectric solvent. The liquid crystal display (LCD) of this invention comprises well-defined microcups filled with at least a liquid crystal composition having its ordinary refractive index matched to that of the isotropic cup material. A novel roll-to-roll process and apparatus of the invention permits the display manufacture to be carried out continuously by a synchronized photo-lithographic process. The synchronized roll-to-roll process and apparatus permits a pre-patterned photomask, formed as a continuous loop, to be rolled in a synchronized motion in close parallel alignment to a web which has been pre-coated with a radiation sensitive material, so as to maintain image alignment during exposure to a radiation source. The radiation sensitive material may be a radiation curable material, in which the exposed and cured portions form the microcup structure. In an additional process step, the radiation sensitive material may be a positively working photoresist which temporarily seals the microcups. Exposure of a selected subset of the microcups via the photomask image permits selective re-opening, filling and sealing of the microcup subset. Repetition with additional colors permits the continuous assembly of a multicolor EPD or LCD display.

    摘要翻译： 本发明涉及一种电泳显示器或液晶显示器及其制造方法。 本发明的电泳显示器（EPD）包括明确形状，尺寸和纵横比的微杯，并且微杯充满分散在光学对比介电溶剂中的带电颜料颗粒。 本发明的液晶显示器（LCD）包括充满至少液晶组合物的明确定义的微杯，其具有与各向同性杯材料相匹配的普通折射率。 本发明的新颖的卷对卷工艺和设备允许通过同步的光刻工艺连续进行显示器制造。 同步的卷对卷工艺和设备允许形成为连续环的预先图案化的光掩模以与预辐射敏感材料的纤维网紧密平行对准的同步运动滚动，因此 以便在暴露于辐射源期间保持图像对准。 辐射敏感材料可以是可辐射固化的材料，其中暴露和固化的部分形成微型杯结构。 在另外的工艺步骤中，辐射敏感材料可以是临时密封微型杯的正性光致抗蚀剂。 通过光掩模图像曝光微杯的选定子集允许选择性重新打开，填充和密封微杯子集。 使用附加颜色重复可以连续组装多色EPD或LCD显示屏。
