Patent ID: 7327080

Claim:
A field emission display comprising: an anode comprising a matrix of pixels; and, a cathode comprising: an insulating layer defining a plurality of wells having a conductor therein; a first conductive layer forming a plurality of conductive pads, each of said conductive pads corresponding to one of said wells; a plurality of nanostructures electrically coupled to said conductive pads; a second conductive layer formed over said insulating layer and providing a plurality of gate electrodes; driver circuitry comprising: first and second n-channel transistors, the first n-channel transistor having gate and drain terminals coupled to a given voltage, and a source terminal coupled to a drain terminal of the second n-channel transistor; and, the second n-channel transistor has a gate terminal for providing a column driver data signal and a source terminal coupled to another given voltage; and a third n-channel transistor having a drain terminal coupled to the source terminal of the first n-channel transistor and the drain terminal of the second n-channel transistor and the input to the pixel circuit stage; wherein a gate terminal of the third n-channel transistor is selectively provided with a horizontal blanking signal and a source terminal of the third n-channel transistor is substantially grounded; wherein, when a potential between said conductive pads and gate electrodes exceeds a threshold voltage, said nanostructures emit electrons that impinge said pixels.
