Patent ID: 8007333

Claim:
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.
