摘要： An inline electron gun for use in a multi-beam electron gun as in a color cathode ray tube (CRT) includes a main focus lens for focusing the electron beams on the CRT's display screen for providing a video image. The main focus lens includes plural charged grids aligned in a spaced manner along the electron gun's longitudinal axis through which plural (typically three) electron beams are directed. One or more of these charged grids includes at least two aligned common apertures for passing the three electron beams. The layered common aperture arrangement allows for increasing the length of the electron gun as well as the effective diameter of the electron gun's main focus lens for improved video image resolution without introducing electron beam astigmatism.

摘要： A multi-beam color index cathode ray tube (CRT) includes vertically spaced, horizontal phosphor stripes on the inner surface of its display screen. The parallel phosphor bands are arranged in groups of three, with each phosphor stripe in a group providing a respective one of the three primary colors of red, green and blue. An electron gun directs three electron beams onto the display screen, with the three electron beams deflected over the display screen in unison in a raster pattern. The three electron beams are focused in the form of three spots on the display screen, with each spot coincident with a respective horizontal phosphor stripe of a given color. The intensity of each electron beam is independently modulated as it sweeps across the width of the display screen by a respective color video signal in accordance with the displayed image. The three electron beams are each provided with a horizontally elongated cross section, with convergence of the beams provided by a plurality of multi-pole adjustable magnets. By horizontally elongating and vertically offsetting the beams, the vertical spacing between the electron beams as well as between the horizontal phosphor stripes may be reduced for improved video image resolution. The closely spaced electron beams may be focused with a conventional main focusing lens employing a common beam-passing aperture, with electron beam alignment with the horizontal phosphor stripes provided via a beam responsive UV emitter/sensor combination and feedback control arrangement.

摘要： An inline electron gun for a color cathode ray tube (CRT) directs electron beams through an Einzel lens common to all of the beams for focusing the beams on a display screen across which the beams are scanned in horizontal scan lines in a raster-like manner. The electron gun includes a beam forming region (BFR) for forming the beams in a matrix array including a plurality of vertically spaced, horizontally aligned apertures, where each horizontally aligned group of apertures passes the primary color electron beams for one scan line on the display screen and vertically aligned apertures are grouped to pass common color electron beams which are horizontally deflected in synchronism over adjacent, vertically spaced scan lines on the display screen. All of the electron beams converge and cross over the electron gun's axis at the center of the Einzel lens, with the diverging beams then directed through a convergence arrangement which converges each group of the horizontally aligned beams to a common spot on a given scan line permitting video display information to be presented simultaneously on more than one scan line. The beam convergence arrangement equalizes the vertical and horizontal convergence effects on each of the beams in the matrix array of beams to deflect the outer beams inwardly while deflecting the upper and lower beams respectively downwardly and upwardly so that each group of horizontally aligned beams converge on the center beam of that group at the display screen.

摘要： An internal resistor within a color cathode ray tube (CRT) is connected to a voltage source and is coupled across a G4 grid and a G6 grid of the CRT's multi-grid quadrupole (QPF) electron gun. De-coupling the G4 grid from the G2 grid in the electron gun's prefocus lens and operating the G4 grid at a higher voltage as used in the gun's high voltage main focus lens moves the equivalent lens of the prefocus and main focus lenses toward the CRT's display screen and reduces electron beam magnification and spot size for improved video image definition and focusing.

摘要： In a multi-stage, multi-beam electron gun of the common lens type for use in a color cathode ray tube (CRT), a charged grid in the prefocus lens of the electron gun is provided with three inline asymmetric beam passing apertures. The three asymmetric apertures may be either in the G4 grid, in the upper side of the G3 grid, or on the lower side of the G5 grid, i.e., in facing relation to the G4 grid, or may be incorporated in both the G3 and G5 grids. The small G3-G4 and G4-G5 spacing gives rise to isolation of the electron optic lenses of the two outer electron beams from that of the center electron beam allowing the asymmetric auxiliary apertures to asymmetrically and independently correct for electron beam astigmatism, i.e., the difference between the beam's horizontal and vertical focus voltage, and differences in the focus voltages of the two outer electron beams relative to the center electron beam. Each of the three inline apertures includes a circular center portion with an overlapping (or superimposed) elliptically shaped aperture. The elliptical aperture may be aligned generally vertically or generally horizontally, and the two outer electron beam passing apertures may be larger or smaller in diameter than the center aperture. In the two outer electron beam passing apertures, the superimposed elliptically shaped aperture may be horizontally offset (either outwardly or inwardly relative to the circular center portion) for controlling static convergence of the three electron beams.

摘要： An electron gun includes plural aligned charged grids each having an aperture (in a monochrome CRT) or plural apertures (in a color CRT) through which an electron beam (or beams) is directed. The beams emitted by a cathode sequentially transit a beam forming region (BFR), a dynamic focus lens and a main focus lens prior to being incident on the CRT's display screen. The electron beam tends to expand in diameter in the direction of the CRT's display screen. This results in an increase in the focusing effect on the electron beam of the electron gun's grids in proceeding from the BFR toward the display screen where the beam passing apertures in the various grids are of the same size. To increase electron beam focusing sensitivity while reducing the beam's dynamic focus voltage, the beam passing apertures in the gun's dynamic focus lens are provided with progressively reduced size in proceeding toward the electron gun's cathode.

摘要： A maskless, direct write electron lithography apparatus for accurately and simultaneously writing plural sub-micron patterns on a silicon substrate employs plural parallel electron beams with precise X-Y mechanical translation of the substrate to provide low cost, high throughput integrated circuit (IC) fabrication. Plural compact micro electron gun assemblies arranged in a I×J rectangular grid each simultaneously expose one IC pattern on the substrate, with each electron gun assembly including a K×L array of individually controlled electron guns emitting K×L electron beams. The regular, small spacing between electron beams in each array, i.e., approximately 1 mm or less, requires a correspondingly small X-Y translation of the substrate to write the entire wafer. Each electron gun array includes plural AC blanked cathodes and DC biased plates having plural aligned beam passing apertures. A computer controlled pattern generator synchronized with wafer X-Y translation controls the duration and timing of the cathode blanking signals.

摘要： An electron gun for use in a cathode ray tube (CRT) includes a cathode, a low voltage beam forming region (BFR), and a high voltage deflection focus lens disposed in the beam deflection region of the CRT's magnetic deflection yoke for simultaneous and coincident focusing and deflection of the electron beam on the CRT's display screen. The deflection lens includes a plurality of first focus grids disposed in the CRT's neck portion including a spaced first pair of grids each having respective beam passing apertures, with one of the beam passing apertures horizontally offset and the other beam passing aperture vertically offset from the electron beam axis. Other grids disposed on opposed sides of each of the first pair of grids have respective beam passing apertures centered with respect to the electron beam axis and are maintained at a fixed focus voltage. A dynamic focus correction voltage which varies with electron beam deflection is applied to each of the first pair of grids for compensating for asymmetric off-axis electron beam defocusing at all points on the CRT's faceplate. This dynamic off-axis defocusing correction is equally applicable in a single beam, monochromatic deflection lens CRT as well as in a multi-beam, color deflection lens CRT.

摘要： A limiting aperture disposed in a low voltage, beam forming region (BFR) of an electron gun in a cathode ray tube (CRT) provides reduced electron beam spot size with low power dissipation. The limiting aperture is located in a low voltage, electrostatic field-free region, preferably in the screen grid electrode G.sub.2, where the field-free region is formed by increasing the thickness of the screen grid electrode G.sub.2 to 1.8 times the diameter of a pair of circular recessed portions in opposing surfaces of the screen grid electrode G.sub.2 which are separated by the small diameter limiting aperture on the electron gun's axis through which the beam is directed. A narrow, relatively electrostatic field-free zone is thus formed in the center of the screen grid electrode G.sub.2 which is maintained at a relatively low voltage, i.e., ranging from approximately 300 V to less than 12% of the anode voltage. The outer electrons in the relatively low energy electron beam are intercepted by the limiting aperture to provide a small, well defined beam spot size on the CRT screen.
