    Abstract: An electrophoretic medium that may be incorporated into an electrophoretic display includes a dispersion that may be contained in a plurality of microcapsules or microcells or a polymeric continuous phase. The dispersion may include a non-polar fluid, a plurality of first charged particles; and an inhibitor of photo-thermally induced polymerization that inhibits potential cross-linking between the particles and/or the microcells or polymeric continuous phase. The inhibitor may be a compound having an unsaturated hydrocarbon ring and at least one of a hydroxyl group, a carbonyl group, and a nitroso group. The plurality of microcells or polymeric continuous phase and a coating of the particles may include a polymeric material that includes (meth)acrylates.

    Abstract: Additives for electrophoretic media comprising esters of branched polyols and fatty acids, such as esters of pentaerythritol propoxylate (5/4 PO/OH) and stearic acid. The fatty acids may be saturated or unsaturated, branched or unbranched. In some embodiments, the fatty acids are perfluorinated, or partially fluorinated. In some embodiments, the branched polyol will include oligomers of polypropylene oxide or polyethylene oxide. When the additives are included in an electrophoretic medium in a display, the resulting display has an improved contrast ratio and reducing ghosting.

    Abstract translation: 用于电泳介质的添加剂包含支链多元醇和脂肪酸的酯，例如季戊四醇丙氧基化物（5/4 PO / OH）和硬脂酸的酯。 脂肪酸可以是饱和的或不饱和的，分支的或不分支的。 在一些实施方案中，脂肪酸是全氟化的或部分氟化的。 在一些实施方案中，支化多元醇将包括聚环氧丙烷或聚环氧乙烷的低聚物。 当添加剂包含在显示器中的电泳介质中时，所得显示器具有改善的对比度并减少重影。

    Abstract: Polyhydroxy sealing formulations for the production of electrophoretic displays, and portions thereof, for example, front plane laminates. When the disclosed polyhydroxy compounds are included in a sealing layer (or in a binder layer), the layer has improved wetting properties, allowing for more consistent application of the layer in a roll-to-roll production process. Additionally, the polyhydroxy compounds can migrate into the electrophoretic medium, where they improve the contrast ratio and reduce ghosting.
