ABSTRACT:
An electrophoretic display device which provides high contrast images and a stable suspending fluid is described. A white marking material such as titanium dioxide is suspended in a colloidal dispersion containing black colorant such as colloidal size iron oxide particles known as ferrofluids. Image formation is achieved electrophoretically by selective application of an electric field across the imaging suspension.
