Abstract: Apparatus and method are provided for a package structure that enables mounting of a field-emitting cathode into an electron gun. A non-conducting substrate has the cathode attached and the cathode is electrically connected to a pin through the substrate. Other pins are electrically connected to electrodes integral with the cathode. Three cathodes may be mounted on a die flag region to form an electron gun suitable for color CRTs. Accurate alignment of an emitter array to the apertures in the electron gun and other electrodes such as a focusing lens is achieved. The single package design may be used for many gun sizes. Assembly and attachment of the emitter array to the electron gun during construction of the gun can lower cost of construction.

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.

Abstract: Apparatus and method for mounting a field emission device having emitters and an extraction grid in an electron gun are provided. The apparatus may be adapted from parts of a conventional electron gun that uses a thermionic emitter. Electrical connection to the grid is provided by bumps that are spring-loaded against a conducting surface, such as the second grid of a conventional electron gun.
