ABSTRACT:
A display comprising:a) a substrate;b) first transparent conductors;d) second conductors patterned to form segments;e) inter-segment material disposed between said second conductors, electrically conductive and having optical properties similar to said second conductors;f) an imaging layer comprising a light-modulating material disposed between said first and second conductors, electrically switched between two field-stable optical states and having a third as-coated optical state; andg) applying an electrical field to said inter-segment material and said first conductors to write said light-modulating material from the as-coated optical state to a different optical state more closely matching one of the two field-stable optical states.
