US Patent 7583427 Components and methods for use in electro-optic displays

A sub-assembly for use in forming an electro-optic display comprises (in this order) a light-transmissive substrate (120); discrete areas (204) of electro-optic material separated by gutter areas (205) essentially free from the electro-optic material; and an adhesive layer (122) and/or a release layer (124) peelable from the sub-assembly. A second sub-assembly comprises (in this order) a peelable release sheet (102); discrete areas of electro-optic material (204) separated by gutter areas (205) essentially free from the electro-optic material, and an adhesive layer (206) and/or a peelable release layer (208). Processes for producing these sub-assemblies and for using them to form electro-optic displays are also described.
