COLORED PIGMENT PARTICLES FOR ELECTROPHORETIC DISPLAYS

摘要

Electrophoretic displays with an electrophoretic medium having charged pigmented microparticles are disclosed. The microparticles are charged linking molecules polymerized with chromophores of various colors so that microparticles in a variety of colors may be produced. Methods for producing the microparticles and using the microparticles in an electrophoretic display are also disclosed. Such microparticles may be provided separately, or kits may be provided for producing the microparticles.

1. An electrophoretic display comprising:
at least one first electrode layer; and an electrophoretic medium disposed adjacent at least one first electrode layer, wherein the electrophoretic medium comprises:
at least one electrically charged particle disposed in a transparent fluid and capable of moving through the transparent fluid upon application of an electrical field to the transparent fluid, wherein at least one charged particle comprises an alternating copolymer of a chromophore and a charged linker molecule.
