Abstract: The emitter plate 60 of a field emission flat panel display device includes a layer 68 of a resistive material and a mesh-like structure 62 of an electrically conductive material. A conductive plate 78 is also formed on top of resistive coating 68 within the spacing defined by the meshes of conductor 62. Microtip emitters 70, illustratively in the shape of cones, are formed on the upper surface of conductive plate 78. With this configuration, all of the microtip emitters 70 will be at an equal potential by virtue of their electrical connection to conductive plate 78. In one embodiment, a single conductive plate 82 is positioned within each mesh spacing of conductor 80; in another embodiment, four conductive plates 92 are symmetrically positioned within each mesh spacing of conductor 90. Also described is an arrangement of emitter clusters including conductive plates 102 having a plurality of microtip emitters 104 formed thereon, or spaced thereform by a thin layer of resistive material, each cluster adjacent and laterally spaced from a stripe conductor 100 by a region 106 of a resistive material.

Abstract: By incorporating two-pole circuits (13) as switching elements in a picture display device based on field emission, the emission (and hence the picture intensity) is substantially defined by the charge of a capacitance (15) associated with a part of a pixel (8). Charge-controlled drive leads to a more accurate adjustment than the voltage-controlled drive used until now and leads to lower drive voltages, less power consumption and a longer lifetime of the phosphors used in the display device.

Abstract: A method for producing microdot emitting cathodes on silicon for compact flat screens, and the products obtained by means of said method, are disclosed. According to the method, the emitting cathodes are made from a basic monolithic silicon substrate (1) consisting of a thick wafer (at least 300 microns) or a thin film a few microns thick on an insulating substrate (alumina or glass), the silicon film being "active" in both cases. The method is useful in the field of flat display screens based on the physical phenomenon of cathodoluminescence and field effect electron emission, and in all industrial sectors using compact display screens, e.g. video camera viewfinders, calculators, monitoring devices of all kinds, vehicles, watches and clocks, etc.
