MATERIALS FOR USE IN ELECTROPHORETIC DISPLAYS

摘要

An electrophoretic medium comprises an electrophoretic layer, a layer of lamination adhesive and a polymeric layer disposed between the electrophoretic layer and the lamination adhesive layer, the polymeric layer being impermeable to the fluid. A second form of electrophoretic medium has a layer of a complex of an alkali metal and a polymer in contact with the electrophoretic layer. A third form of electrophoretic medium comprises a plurality of discrete droplets of internal phase in a binder, and further comprises a salt.

1. A polymer-dispersed electrophoretic medium comprising:
an electrophoretic layer comprising a plurality of discrete droplets of an internal phase in a binder, the internal phase comprising plurality of particles disposed in a fluid, the particles being capable of moving through the fluid upon application of an electric field to the medium; and a layer of a complex of an alkali metal and a polymer in contact with the electrophoretic layer.
