摘要： In order to allow application of any coating under a vacuum over a volatile gelatinous layer, such as polymer dispersed liquid crystal (PDLC) on an optical glass substrate with a transparent electrode, such as indium tin oxide (ITO) on its surface, a layer of an intermediate stress absorbing polymeric material is first applied to cover the volatile gelatinous layer to prevent evaporation and escape of volatiles, thereafter the coating is applied under a very high vacuum using for example a technique called Physical Vapor Deposition (PVD) or sputtering.

摘要： Embodiments of polymer dispersed liquid crystals (PDLCs) in accordance with the present invention comprise TL-series liquid crystal materials and a polymer matrix comprising polyacrylate resins having hydroxyl groups. These hydroxyl groups allow crosslinking by using isocyanate, improving mechanical properties and heat resistance. Typical ratios of liquid crystal to polymer range between about 50/50 to 70/30 (wt/wt). The PDLC materials exhibit enhanced sensitivity to driving voltages and higher transmission ~voltage (T-V) curve slope. In testing thin film transistors (TFTs), these PDLC materials can be used to compensate for an increased air gap accommodating flatness variation in the TFT substrate, and to reduce electrostatic forces between modulator and panel. Embodiments of PDLC materials in accordance with the present invention form solid films upon evaporation of the solvent. Homogeneity of embodiments of solvent-based PDLC formulations in accordance with the present invention allow for the use of many different coating methods, such as spin, doctor blade, and slot-die coatings.
摘要翻译：根据本发明的聚合物分散液晶（PDLC）的实施方案包括TL系列液晶材料和包含具有羟基的聚丙烯酸酯树脂的聚合物基体。这些羟基允许通过使用异氰酸酯进行交联，改善机械性能和耐热性。液晶与聚合物的典型比例在约50/50至70/30（wt / wt）之间。 PDLC材料对驱动电压和更高的透射电压（T-V）曲线斜率具有增强的灵敏度。在测试薄膜晶体管（TFT）时，这些PDLC材料可用于补偿TFT基板中容纳平坦度变化的增加的气隙，并减少调制器和面板之间的静电力。根据本发明的PDLC材料的实施方案在溶剂蒸发时形成固体膜。根据本发明的基于溶剂的PDLC制剂的实施方案的均匀性允许使用许多不同的涂布方法，例如旋涂，刮刀和狭缝模头涂层。

摘要： An electro-optic modulator assembly includes a sensor layer made from an electro-optic modulator material that comprises liquid crystal droplets encapsulated within a polymer matrix. The sensor layer material comprises an interfacial agent, for example a defoaming agent, in an amount sufficient to lower an intrinsic operating voltage at which the sensor layer transmits light. The defoaming agent can comprise from about 1 to about 10 percent by weight of the electro-optic modulator material, and the defoaming agent may comprise a reactive component to react with the polymer matrix, for example at least one of a siloxane with a reactive end group, a reactive fluorinated polymer or a non-ionic block copolymer to react with the polymer matrix. The assembly can also include a hard coating layer to protect the sensor layer.

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-lithorgrahic 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.
