Abstract:
A field emission display including a faceplate having an active area surface and a cathodic structure formed on a backplate, said cathodic structure comprising:a first metal layer disposed over said backplate so as to form a plurality of metal strips, said first metal layer formed of aluminum;a cladding layer disposed over said first metal layer such that said first metal layer and said cladding layer form a plurality of cladded metal strips, said cladding layer formed of an electrically conductive material and electrically coupled to said first metal layer;a resistive layer formed over said cladding layer and electrically coupled to said cladding layer; anda plurality of emitters electrically coupled to said resistive layer such that, upon the application of power to said cladded metal strips, electrical current selectively flows through said resistive layer and selectively engages said emitters to generate electrons which are for striking said active area of said faceplate to generate a visible display.
