Abstract
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.
