Abstract:
A field emission display, comprising:a baseplate comprising:an emitter substrate;a plurality of emitters formed on the emitter substrate;an extraction grid positioned adjacent to an emitter substrate, the extraction grid having a plurality of openings aligned with respective emitters; andan electrostatic discharge device integrally formed with the baseplate, the electrostatic discharge circuit device coupled between at least some of the emitters and the extraction grid, the electrostatic discharge device being operable to conduct current when a voltage differential between the extraction grid and a respective emitter has a magnitude that exceeds a maximum voltage; anda faceplate positioned opposite and in parallel with the baseplate, the faceplate comprising:a transparent viewing screen;a layer of transparent conductive material coating a surface of the transparent viewing screen facing the emitters; anda layer of cathodoluminescent material coating the layer of transparent conductive material.
