ABSTRACT:
An electron injection structure for the beam guide meshes of a flat panel display has apertures with different dimensions to optimize beam focusing for different purposes. The first period of apertures has strong focusing normal to the plan of the guide meshes. A plurality of periods have strong focusing in a direction parallel to the lateral dimension of the guide meshes. Another plurality of apertures matches the beams to the propagation section of the beam guide.
