摘要:
An electrophoretic display liquid including a dispersion medium, a first granular material having one or more hollows therein and a color and a second granular material having a color different from the color of the first granular material. When an imagewise electric field is applied to the display liquid, the second granular material electrophoreses in a direction, resulting in formation of an image of the second granular material in the display liquid.
摘要:
An electrophoretic display method, using a display dispersion system which includes a dispersion medium, at least one electrophoretically movable coloring material (A) of coloring particles, and at least one electrophoretically immovable coloring material (B) of coloring particles, each of the coloring materials (A) and (B) having a different color tone and being dispersed in the dispersion medium, including the step of selectively causing the coloring material (A) to electrophoretically migrate through the dispersion medium in a predetermined direction in response to an electric field externally applied thereto, while causing the electrophoretically immovable coloring material (B) to stay in the dispersion medium. An electrophoretic display apparatus is provided with the display medium and a recording unit.
