A display includes a substrate and an emitter formed on the substrate. A first dielectric layer is formed on the substrate to have a thickness slightly less than a height of the emitter above the planar surface and includes an opening formed about the emitter. The display also includes a conductive extraction grid formed on the first dielectric layer. The extraction grid includes an opening surrounding the emitter. The display further includes a second dielectric layer formed on the extraction grid and a focusing electrode formed on the second dielectric layer. The focusing electrode is electrically coupled to the emitter through an impedance element. The focusing electrode includes an opening formed above the apex. The focusing electrode provides enhanced focusing performance together with reduced circuit complexity, resulting in a superior display.
