Method of forming field emission light emitting device including the formation of an emitter within a nanochannel in a dielectric matrix

A method of forming a field emission light emitting device comprising:

• providing a substantially transparent substrate;
• forming one or more first electrodes over the substantially transparent substrate, wherein each of the one or more first electrodes comprises a substantially transparent conductive material;
• forming a light emitting layer over each of the one or more first electrodes;
• forming one or more second electrodes disposed over a backing substrate;
• forming one or more nanocylinder electron emitter arrays over each of the one or more second electrodes using a method comprising:
• forming a dielectric matrix over the second electrode;
• forming a third electrode disposed over the dielectric matrix;
• providing a plurality of nanochannels through the third electrode and through the dielectric matrix, wherein the second electrode is exposed at the bottom of each nanochannel;
• and
• forming an electron emitter within each of the plurality of nanochannels in the dielectric matrix, wherein each emitter comprises a first end connected to the second electrode and a second end positioned to emit electrons;
• providing a plurality of spacers connecting the substantially transparent substrate to the backing substrate to provide a predetermined gap between the one or more first electrodes and the one or more second electrodes;
• and
• evacuating and sealing the predetermined gap to provide a low pressure region between the one or more first electrodes and the one or more second electrodes.
