A triode field emission display using carbon nanotubes having an excellent electron emission characteristic is provided. By forming extraction electrodes for controlling emitted electrons around an anode on a front substrate, the triode field emission display (FED) using carbon nanotubes has a simple structure like a diode FED, thereby facilitating manufacture using vapor deposition of carbon nanotubes and allowing control of anode current using extraction electrodes. Accordingly, a large FED can be simply manufactured.

Triode field emission display using carbon nanobtubes

A field emission display that is simple to manufacture in a large screen size and that provides improved display characteristics, includes first and second substrates provided opposing one another with a predetermined gap therebetween; a plurality of gate electrodes formed on a surface of the first substrate opposing the second substrate, the gate electrodes being formed in a striped pattern; an insulation layer formed on the first substrate covering the gate electrodes; a plurality of cathode electrodes formed on the insulation layer in a striped pattern to perpendicularly intersect the gate electrodes; a plurality of surface electron sources formed along one long edge of the cathode electrodes; focusing units provided on the cathode electrodes for controlling the emission of electron beams from the surface electron sources; an anode electrode formed on a surface of the second substrate opposing the first substrate; and a plurality of phosphor layers formed on the anode electrode.

Field emission display having improved capability of converging electron beams

A triode field emission device using a field emission material and a driving method thereof are provided. In this device, gate electrodes serving to take electrons out of a field emission material on cathodes are installed on a substrate below the cathodes, so that the manufacture of the device is easy. Also, electrons emitted from the field emission material are controlled by controlling gate voltage.

Triode structure field emission device

A method for fabricating a triode field emitter array using carbon nanotubes having excellent electron emission characteristics is provided. In the method for fabricating a triode-structure carbon nanotube field emitter array, a catalyst layer is formed on a cathode electrode without forming a base layer, and carbon nanotubes are grown on the catalyst layer using a Spind't process. In this method, a non-reactive layer is formed on a catalyst layer outside the micro-cavity such that the carbon nanotubes can be grown only on the catalyst within the micro-cavity. Accordingly, even through a separation layer is etched and removed, since carbon nanotubes do not exist outside the micro-cavity, it does not happen that carbon nanotubes are drifted into the micro-cavities. Therefore, the fabrication yield is increased, and the fabrication cost is decreased.
