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: The specification describes a method and apparatus for electron beam lithography wherein a Wehnelt electron gun is modified to improve the uniformity of the electron beam. A mesh grid is applied to the Wehnelt aperture and the mesh grid functions as a multiple secondary emitter to produce a uniform beam flux over a wide area. The grid voltage of the modified gun is substantially lower than in a conventional Wehnelt gun, i.e. less than 100 volts, which can be switched conveniently and economically using semiconductor drive circuits.

Abstract: An electron source comprises at least one cathode means, and at least one extractor grid which is used to extract electrons from the cathode means. The extractor grid is a substantially planar sheet having at least one aperture and also has at least one spacing member for spacing the extractor grid at a constant, predetermined spacing from the cathode. Each of the spacing members are formed by removing material around a substantial portion of the periphery of the aperture and folding the remaining portion of the periphery of the aperture at substantially a right angle to the planar sheet.

Abstract: The present invention provides an electron gun which includes an electrically non-conductive substrate through which a perforation is provided. The electron gun is characterized in that a cathode-structure supporting member is welded to power-feeding members that are bonded to a stem side of the electrically non-conductive substrate, the cathode-structure supporting member supplying power to a heater included in a cathode structure. Structured as such, it becomes possible to reduce the size of the electron gun in the tube-axis direction, since an additional member for supporting the heater becomes unnecessary. In addition, the cathode-structure supporting member makes the electrically non-conductive substrate to work as a wiring board for supplying voltage to the cathode, thereby realizing a slim cathode-ray tube. Further, the above structure improves accuracy in the assembly process of the electron gun, thereby improving the yield factor.

Abstract: Among a plurality of electrodes composing an electron gun, at least one electrode is separated into two along a plane substantially perpendicular to a central axis, the two being a first cylindrical electrode and a second cylindrical electrode. Between the two electrodes, a connecting member in an approximate cylindrical shape having a slit is interposed, which electrically connects the first and second cylindrical electrodes with each other. The first and second cylindrical electrodes are fixed to a support rod via the connecting member and support portions provided on a side of the connecting member. Since a modulation magnetic field from outside a cathode-ray tube passes through the slit, eddy current loss can be reduced, whereby a desired electron beam modulation effect can be achieved. Furthermore, since no slit is formed in the first and second cylindrical electrodes, it is possible to avoid distortion of electrodes that is caused when slits are formed in the electrodes, as well as distortion of an electron lens due to the distortion of the electrodes.

Abstract: Cathode venting for electron guns is improved by forming one or more vent holes around the apertures in the triode and any pre-focus lens. This configuration places the vent holes next to the active area of the cathode and provides a line of sight from the cathode to the funnel. If separate alignment holes are used to protect the aperture, one or more vent holes are provided in addition to the alignment holes. The pattern of vent and alignment holes is preferably rotationally symmetric about the aperture so that they do not effect the beam.

Abstract: A color display device with an improved focus performance. Conventional color display tubes with DAF have an electron gun with a second focusing electrode (25) driven with a dynamic voltage which is varied synchronously with the deflection field. The dynamic quadruple lens formed between the first focusing electrode (23) and the second focusing electrode (25) is designed such that the horizontal lens action, which arises when the voltage on the second focusing electrode is increased, should be compensated by the main lens which becomes weaker when the voltage on the second focusing electrode is increased. In practice, this is not possible in the required range of the dynamic voltage on the second focusing electrode, leading to a deterioration of the focus performance of the color display device. This problem is solved by applying a dynamic voltage to the first focusing electrode so that it is possible to focus the electron spots on the display window (3) in the horizontal and vertical directions, resulting in an optimally focused picture.
