Patent number: 11934081Abstract: An electro-optic device, and its method of manufacturing, is disclosed comprises a first substrate layer, a conductive film comprising a first adhesive layer and a first electrode layer, an electro-optic material layer, and a second electrode layer. The first electrode layer, which is on contact with the electro-optic material layer, comprises a conductive material, such as conductive particles, a metallic material or a conductive polymer. The first adhesive layer has high storage modulus and does not exhibit plastic flow under the conditions of manufacturing, storage, and operation of the electro-optic device. The conductive film does not conform to the surface roughness of the first surface of the electro-optic material layer. The conductive film may be designed to be thin, flexible and transparent. The resulting electro-optic device exhibit excellent electro-optic performance even where the electro-optic material layer has imperfections in the form of gaps.Type: GrantFiled: December 7, 2020Date of Patent: March 19, 2024Assignee: E Ink CorporationInventors: Nishit Murari, Jay William Anseth
