Patent ID: 8217857

Claim:
A display, comprising: a planar display section; a pixel space provided next to a side adjacent to one surface of the display section and encapsulating a plurality of kinds of colorants, each kind having a different color; an accumulation section provided in the pixel space and accumulating the colorants; a separation system that separates a specific kind of colorant from the accumulated colorants in the accumulation section; a transfer system that selects at least one kind of colorant from the separated colorants and transfers the selected colorant to the side adjacent to the display section of the pixel space, wherein: the separation system performs separation utilizing difference in a magnitude of a dielectrophoretic force generated in each colorant upon receipt of an alternating electric field of a specific frequency applied by this system, the magnitude varying depending on the kind of the colorant, a color of at least the one kind of colorant transferred by the transfer system is displayed at the display section, the separation system selects and separates the specific kind of colorant from the accumulated colorants by applying, as a driving force, an alternating electric field of a specific frequency at which a dielectrophoretic force is generated in the specific kind of colorant out of the colorants, the dielectrophoretic force being greater than those generated in other kinds of colorants, the separation system further comprising a pair of electrodes for electrophoresis that applies a direct or pulse electric field and a circuit that applies a voltage between the pair of electrodes for electrophoresis and separates the specific kind of colorant while electrophoretically migrating the colorants by the action of the electric field.
