    Abstract: An electron source include a first cathode electrode disposed over a substrate and terminated to provide electrons; an emitter layer disposed over the cathode electrode and formed from one or plurality vertically aligned and mono-dispersed nano-structures that are truncated to the same length, embedded in a solid matrix and protruding above the surface for emitting electrons; an insulator disposed over the emitter layer and having one or plurality of apertures, each is self-aligned with and exposes one nano-structure in the emitter layer; and a second gate electrode disposed over the insulator, having one or plurality of apertures self-aligned with the apertures in the insulator and terminated to extract electrons from the exposed nano-structures through the apertures. The gate aperture is substantially less than one micrometer and the gated nano-structures can have a density on the order of 108/cm2. Such an electron source can be modulated with an extra low voltage, emits electrons with high current density and high uniformity, and operates with high energy-efficiency and long lifetime.

    Abstract: Apparatus and method are provided for using a multi-element field emission cathode in a color cathode ray tube. The field emission cathode may have from four to ten field emission arrays linearly arranged. The arrays are preferably formed from carbon-based material. An electron gun assembly focuses electron beams from each array on to a phosphor stripe or dot on the screen of the cathode ray tube. Deflection apparatus moves the beam from each field emission array according to clock signals. Clock signals also turn on or turn off voltage to contacts controlling electron current from the array. Values of voltage applied, determined by a video signal, determine the intensity of electron current from each array, which controls the intensity of the light emitted by each color stripe or dot of phosphor on the phosphor screen.
