    Abstract: A flat panel display having a repair capability, a process for repairing such a display having defects involving short circuits between a field emission tip and an adjacent conductor, and a process for forming a flat panel display with repair capability, are described. The flat panel display has a dielectric base substrate, upon which are formed cathode columns of parallel, spaced conductors. Gate lines, also formed of parallel, spaced conductors, are located over and perpendicular to the cathode columns. A dielectric layer is formed between the cathode columns and the gate lines. Pixels of the display are located at the intersections of the cathode columns and the gate lines. A plurality of openings are formed in the gate lines and in the dielectric layer, at each of the pixels. A plurality of field emission microtips, at each of the pixels, connects to and extends up from the cathode columns and into the openings. Slots in the gate lines are formed contiguously between the openings and parallel to the direction of the gate lines, whereby the slots provide a repair capability. The flat panel display is tested to detect the defect, located at an emitter location. The gate line is cut, preferably with a laser beam, on both sides of the emitter.

    Abstract: Applicants have discovered methods for making electron emitters using commercially available diamond particles treated to enhance their capability for electron emission under extremely low electric fields. Specifically, applicants have discovered that electron emitters comprising ultra-fine (5-10,000 nm) diamond particles heat-treated by a hydrogen plasma, can produce electron emission current density of at least 0.1 mA/mm.sup.2 at extremely low electric fields of 0.5-1.5 V/.mu.m. These field values are about an order of magnitude lower than exhibited by the best defective CVD diamond and almost two orders of magnitude lower than p-type semiconducting diamond. Emitters are preferably fabricated by suspending the ultra-fine diamond particles, preferably in the nanometer size range, in an aqueous solution, applying the suspension as a coating onto a conducting substrate such as n-type Si or metal, and then subjecting the coated substrate to a plasma of hydrogen, preferably at temperatures above 300.degree. C. for a period of 30 minutes or longer. The resulting emitters show excellent emission properties such as extremely low turn-on voltage, good uniformity and high current densities. It is further found that the emission characteristics remain the same even after the plasma treated diamond surface is exposed to air for several months.

    Abstract: A field emission display includes an emitter driving circuit for providing current to emitters in the display. The emitter driving circuit includes a current mirror to monitor actual current to each pixel in the array. The actual current is then compared to a reference current derived from an image signal based upon an expected current draw of the emitter to produce an error signal. The error signal is fed back to the input of the emitter driver circuit and the emitter driver circuit produces a corrected emitter current in response. During transitions in the image signal, error detection is briefly disabled to allow the emitter driver circuit to respond to the image signal.

    Abstract: Applicants have discovered methods for making, treating and using diamonds which substantially enhance their capability for low voltage emission. Specifically, applicants have discovered that defect-rich diamonds--diamonds grown or treated to increase the concentration of defects--have enhanced properties of low voltage emission. Defect-rich diamonds are characterized in Raman spectroscopy by a diamond peak at 1332 cm.sup.-1 broadened by a full width at half maximum .DELTA.K in the range 5-15 cm.sup.-1 (and preferably 7-11 cm.sup.-1). Such defect-rich diamonds can emit electron current densities of 0.1 mA/mm.sup.2 or more at a low applied field of 25 V/.mu.m or less. Particularly advantageous structures use such diamonds in an array of islands or particles each less than 10 .mu.m in diameter at fields of 15 V/.mu.m or less.
