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.
In a matrix addressing arrangement forming part of a matrix addressed flat panel display utilizing a matrix array of field emission cathodes that are selectively addressed by said arrangement, the latter including dielectric means supporting a first lower planar array of spaced apart, parallel electrically conductive leads electrically connected with and supporting said cathodes and a second upper planar array of spaced apart, parallel electrically conductive leads located above and spaced from said first array such that said second leads extend normal to said first leads, the improvement comprising
In a matrix addressing arrangement especially suitable for use as part of a matrix addressed flat panel display or other such device requiring matrix addressing, said arrangement including dielectric means supporting a first planar array of spaced apart, parallel, electrically conductive leads, a second planar array of spaced apart, parallel, electrically conductive leads located above and spaced from said first array such that the said second leads extend normal to said first leads, and at least one layer of dielectric material between said first and second arrays for electrically insulating the two arrays from one another, the improvement comprising:
