Display system, manufacture method thereof and display medium

A display system, built up of at least one display cell comprising:

• an assembly which includes at least a first electrode and a second electrode and in which there are mutually non-miscible first and second liquids filled, wherein either one of said first and second electrodes is electrically insulated from said first and second liquids, said first liquid has electrical conductivity or polarity, and voltage is applied to one or both of said first and second electrodes, whereby said first liquid and said second liquid vary in position to produce a display, and
• even after an applied voltage is shut off at a position to which said first and second liquids have migrated, positions of said first and second liquids that have migrated are retained to keep memory capability going on;
• and
• further comprising a second electrode for retaining the positions of said first and second liquids that have migrated, after the applied voltage is shut off at the positions of said first and second liquids that have migrated,
• wherein said assembly comprises a set of substrates, at least one of which is transparent, a wall portion for holding said set of substrates in opposition to one another in such a way as to define a liquid confining space, a 1st-A electrode located on one substrate that faces said liquid confining space, a 1st-B electrode located on another substrate that faces said liquid confining space, and
• wherein the second electrode is located substantially parallel with said 1st-A electrode and said 1st-B electrode and adapted to divide said liquid confining space, wherein said second electrode has a plurality of through-holes in at least a part, said 1st-A electrode and said 1st-B electrode are electrically insulated from said first and second liquids;
• at a voltage applied to said 1st-A electrode and said second electrode or a voltage applied to said 1st-B electrode and said second electrode, said second liquid passes through the through-holes in said second electrode to be able to migrate between said liquid confining space on said 1st-A electrode and said liquid confining space on said 1st-B electrode.

The display system built up of at least one display cell comprising:

• an assembly which includes at least a first electrode and a second electrode and in which there are mutually non-miscible first and second liquids filled, wherein either one of said first and second electrodes is electrically insulated from said first and second liquids, said first liquid has electrical conductivity or polarity, and voltage is applied to one or both of said first and second electrodes, whereby said first liquid and said second liquid vary in position to produce a display, and
• even after an applied voltage is shut off at a position to which said first and second liquids have migrated, positions of said first and second liquids that have migrated are retained to keep memory capability going on;
• and
• further comprising an oil repellent layer for retaining the positions of said first and second liquids that have migrated, after the applied voltage is shut off at the positions of said first and second liquids that have migrated,
• wherein said assembly comprises a set of substrates, at least one of which is transparent, a wall portion for holding said set of substrates in opposition to one another in such a way as to define a liquid confining space, a 1st-A electrode and a 1st-B electrode that are located on one substrate that faces said liquid confining space in an electrically independent way, and
• wherein the oil repellent layer is located at a boundary site between said 1st-A electrode and said 1st-B electrode, a lipophilic layer located in such a way as to cover said 1st-A electrode and said 1st-B electrode at a site with no said oil repellent layer located, and a second electrode that is located on another substrate that faces said liquid confining space, wherein said 1st-A electrode and said 1st-B electrode are electrically insulated from said first and second liquids;
• and at a voltage applied to said 1st-A electrode and said second electrode or a voltage applied to said 1st-B electrode and said second electrode, said second liquid goes over said oil repellent layer to be able to migrate between on said 1st-A electrode and on said 1st-B electrode.
