Abstract:
An electronic display apparatus, comprising:an ion source;a phosphor;a first substrate, disposed between and spaced from the ion source and the phosphor, defining an aperture for passage of ions therethrough;a focusing electrode, disposed on the substrate, including a conductive surface facing the ion source;a first displacing electrode associated with the substrate, for displacing an ion stream passing through the aperture through a first displacement path;first and second pinch electrodes associated with the aperture, for exerting a force to squeeze the ion stream in a direction perpendicular to the displacement path; anda second substrate disposed between the ion source and the phosphor, the second substrate defining an aperture therein which is aligned with the aperture in the first substrate;wherein at least one of the displacing electrode or the pinch electrodes are disposed on the second substrate.
