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.
可纳入电泳显示屏的电泳介质包括分散体,分散体可包含在多个微胶囊或微孔或聚合物连续相中。分散液可包括非极性流体、多个带第一电荷的微粒;以及可抑制微粒和/或微孔或聚合物连续相之间潜在交联的光热诱导聚合抑制剂。抑制剂可以是具有不饱和烃环和羟基、羰基和亚硝基中至少一种的化合物。多个微孔或聚合物连续相和颗粒涂层可包括一种包含(甲基)丙烯酸酯的聚合物材料。
