Abstract: In a field emission type image display panel, plural cathode electrodes are formed in a stripe shape on a first substrate and each having emitters for field emission. Cathode lead-out electrodes supply signals to the cathode electrodes. Plural patch-like gate electrodes are arranged in a matrix form over the plural cathode electrodes and insulated from the plural cathode electrodes. Gate lead-out electrodes are led out along spaces between adjacent two rows in rows formed of patch-like gate electrodes substantially perpendicular to the cathode electrodes, each of the gate lead-out electrodes being connected to the patch-like gate electrodes in adjacent two rows in a zigzag arrangement and every other gate electrode. A second substrate is spaced from the first substrate a predetermined distance apart. Plural patch-like anode electrodes are arranged on the second substrate, the plural anode electrodes respectively confronting the plural patch-like gate electrodes in a matrix form. Fluorescent materials are formed over the plural patch-like anode electrodes, for displaying an image. Anode electrodes are led out along spaces between adjacent two rows of anode electrodes substantially perpendicular to the cathode electrodes, each of the anode lead-out electrodes being connected to anode electrodes in adjacent two rows in a zigzag arrangement and every other anode electrode.

Abstract: A current controlled field emission display includes a current control circuit coupled to respective emitters to control current flow through the emitters. The control circuit includes a limiting resistor to limit the current flow to the emitters. To compensate for temperature or other variations in the resistance of the limiting resistor, the control circuit also includes a compensating resistor that produces an offsetting change in a driving voltage within the control circuit. As the resistance of the limiting resistance drops, which would allow the current through the emitter to increase, the compensating resistor produces an offsetting voltage drop that increases the voltage across the limiting resistance to maintain the current through the limiting resistance constant. The offsetting current reduction thus reduces the overall effect of temperature on current flowing through the emitter set.

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.

Abstract: A novel and advantageous cathode structure for a field emission display apparatus is disclosed. A given pixel comprises a multiplicity of spaced apart emitter bodies on a support. A given emitter body comprises diamond and/or rare earth boride, and has a relatively sharp geometrical feature that facilitates electron emission from the emitter body. By way of example, the emitter body comprises diamond bodies grown on a support, or it comprises a pre-existing diamond particle that was placed on the support. Such emitter bodies generally can be provided easily and at low cost, and typically have naturally occurring sharp geometrical features such as points and edges. We have also discovered that appropriately grown rare earth boride films of thickness 30 nm or less may substantially improve electron emission from emitter bodies, and some preferred embodiments of the invention comprise a cathode structure that comprises a thin layer of, e.g., LaB.sub.6 on the emitter bodies. Methods of making cathodes according to the invention are also disclosed.
