ABSTRACT:
A matrix addressed flat panel display, is disclosed herein and includes a lower planar array of spaced apart, parallel, electrically conductive leads and a matrix array of field emission cathodes connected to and extending up from the lower planar array of electrically conductive leads. An upper matrix array of spaced-apart parallel electrically conductive leads is located above and spaced from the lower array of leads and from the cathodes, such that the upper leads extend normal to the lower leads, crossing the latter immediately above the cathodes, and such that those segments of the upper leads that actually cross over the lower leads are positioned in a plane closer to the lower leads than the rest of the upper leads. The upper and lower planar arrays of leads are electrically insulated from one another by means of a pair of separately formed layers of dielectric material disposed therebetween.
