ABSTRACT:
A microtip structure with high uniformity, low operating voltage and no resistive dissipation for a field emission display is described. A substrate is provided. A first conductive layer is formed on the substrate that acts as a cathode. A second conductive layer with a narrow circular opening acts as a gate. A first dielectric layer separates the cathode and the gate. The microtip extends up from the cathode and into the opening. A second dielectric layer is over the gate, with a circular opening that is larger than and concentric with the narrow circular opening in the gate. A means to provide a brief, charging voltage to the gate, followed by a longer operational voltage, wherein the amplitude of the operational voltage is lower than the amplitude of the charging voltage, is included.
