A circuit for implementing a registration-free, contiguous conductive
plane. A circuit may include a plurality of conductive structures in a
first plane. The circuit may further include a contiguous conductive
equipotential surface in a second plane parallel to the first plane. The
circuit may further include activation means configured to adjust an
electric field between the first and second planes thereby activating one
or more structures in the first plane by increasing a potential
difference between the first and second planes to a threshold level
deemed to constitute an active state. The circuit may further include
deactivation means configured to adjust the electric field between the
first and second planes thereby deactivating one or more structures in
the first plane by decreasing the potential difference between the first
and second planes below a threshold level deemed to constitute a
deactivated state.
