<p>Electron emitter structure for field emission display, said disp lay comprising a tabular vacuum chamber confined between a rigid transparent front plate and a substantially flat electron emitting structure comprising a plurality of emitting elements, the residual contaminant gas molecules being removed by transversal pumping through a plurality of pores spread out on said electron emitting structure in order to reach a layer of getter material uniformly distributed over the display area. The emitting elements may be provided by Spindt emitters, sharp or serrated metallic edges or carbon nanotubes. The electron emitting structure comprises an upper and a lower metallic layers plated over the upper and lower surfaces of an insulating plate, the latter consisting of a photo-etchable or plasma-etchable material, such as polyimide or SU8.</p> |
