An electrophoretic display module is described, including various types of backsheets and edge seals for protecting electro-optic displays from environmental contaminants. In particular, the disclosed modular design allows a very narrow edge seal, i.e., a thickness of less than 1 mm. In one type of seal, an electro-optical layer is sandwiched between a back plate and a protective sheet, and a sealing material extends between the back plate and the protective sheet. In some cases, the protective sheet includes multiple layers of transparent material to provide physical protection and reduce intrusion of water. 本发明描述了一种电泳显示器模块，包括用于保护电光显示器免受环境污染物影响的各种类型的背板和边缘密封件。特别地，所公开的模块设计允许非常窄的边缘密封件，即厚度小于1mm。在一种类型的密封件中，电光层夹在背板和保护片之间，并且密封材料在背板和保护片之间延伸。在一些情况下，保护片包括多层透明材料以提供物理保护并减少水的侵入。
