Diode structure flat panel display

A diode structure flat panel display, comprising:

• a cathode assembly having a plurality of cathodes, each cathode including a layer of cathode conductive material and a layer of a low effective work-function material disposed over said cathode conductive material;
• an anode assembly having a plurality of anodes, each anode including a layer of anode conductive material and a layer of cathodoluminescent material disposed over said anode conductive material;
• and
• means for maintaining a relatively constant gap between said cathode and anode assemblies.

A flat panel display, comprising:

• a cathode assembly having a plurality of cathodes, each cathode including a layer of cathode conductive material and a layer of low effective work-function material disposed over said cathode conductive material, wherein said cathode assembly further comprises a cathode substrate under said cathode conductive material;
• an anode assembly having a plurality of anodes, each anode including a layer of anode conductive material and a layer of cathodoluminescent material disposed over said anode conductive material;
• and
• means for maintaining a relatively constant gap between said cathode and anode assemblies, wherein said gap maintaining means comprises a plurality of spacers, wherein each of said spacers corresponds with ones of said pluralities of cathodes and anodes, and wherein said plurality of spacers are spaced-apart from said plurality of cathodes,
• wherein said cathode conductive material contains a plurality of recesses in a surface proximate said anode assembly, wherein said recesses are adapted to receive said spacers, and wherein said recesses and said spacers form a circuitous path to thereby minimize electron-induced conduction between said plurality of cathodes and anodes.
