Abstract: Tapered silicon structures, of interest for use, e.g., in atomic force microscopes, in field-emission devices, and in solid-state devices are made using silicon processing technology. Resulting tapered structures have, at their tip, a radius of curvature of 10 nanometers or less.

Abstract: Tapered silicon structures, of interest for use, e.g., in atomic force microscopes, in field-emission devices, and in solid state devices are made using silicon processing technology. Resulting tapered structures have, at their tip, a radius of curvature of 10 nanometers or less. Such preferred silicon structures are particularly suited as electron emitters in display devices.

Abstract: Four parallel spaced-apart substrates are arranged in a stack to provide three gas-containing spaces therebetween. Orthogonally disposed electrodes and dielectric barrier ribs formed on each facing surface of the substrates define individually addressable cells within each gas-containing space. Each picture element comprises three vertically aligned cells each of which contains a gas that, when activated, emits red, green or blue light, respectively. The non-phosphor full-color plasma display device thus formed is characterized by high-resolution and useful memory margins at high frequencies.

Abstract: A method of fabricating a display panel on a substrate material of soda-lime float glass. A dielectric layer composed of a mixture of lead, silicon and aluminum is deposited on the substrate to a thickness of from 25 to 150 microns. A masking pattern is defined on the surface of the dielectric layer where plasma display cavities are to be formed. Openings are etched in the dielectric layer with fluoboric acid to geometries no larger than approximately 0.15 mm wide by 0.15 mm thick at regions defined by the masking pattern, the openings extending to the major surface of the substrate and forming a plasma display cavity. A cover is provided over the cavity to form an enclosed envelope containing a noble gas. A phosphor is provided in the plasma display cavity together with electrodes adjacent to the cavity for ionizing the gas and exciting the phosphor.

Abstract: A high-resolution flat-panel plasma display device made in solid-state form and designed for large-area full-color applications includes first and second sets of orthogonally disposed electrodes on a substrate to which a phosphor-containing faceplate is sealed. The electrodes of one set are respectively suspended relatively high above the substrate surface on spaced-apart longitudinally extending dielectric ridges.

Abstract: A display panel comprising a gas-filled envelope containing an array of rows and columns of D.C. scan/address cells, each scan/address cell including a volume of gas and an anode electrode and a cathode electrode, and an array of rows and columns of display cells, each display cell including a volume of gas and two electrodes, one electrode being in the form of an apertured plate whose apertures are the display cells, the other electrode being an apertured electrode whose apertures are considerably smaller than the apertures in the one electrode and so numerous that the greater portion of the area of the other electrode is light-transmissive whereby the human eye does not see the solid portions of the other electrode which define the apertures therein.

Abstract: A gas-filled display panel comprising a glass base plate and a glass face plate hermetically sealed together along a perimeter seal area to form an envelope which is filled with an ionizable gas, the base plate having an array of longitudinal slots in which anode wires are seated and having an array of cathode electrodes on the top surface thereof. The base plate has cross grooves transverse to the slots and positioned one near each end of the base plate, and a glass rod is secured in each cross groove with the ends of each rod lying within the seal area between the base plate and the face plate, the top surface of each insulating member being generally coplanar with the top surface of the base plate in the seal area, to insure the formation of a hermetic seal between the base plate and face plate at the cross grooves.

Abstract: A method of making a display panel comprising the steps of providing a glass base plate with an array of slots and securing an anode electrode in each slot; forming parallel depressions in one surface of a thin sheet of metal, and then securing it to the top surface of the base plate, with the unetched surface up and the depressions down, and then removing the material of the unetched surface of the metal sheet down to the depressions to form separate strips of metal as cathodes, on the top surface of the base plate; and finally assembling the other electrodes and parts of the panel with the base plate carrying the anode and cathode electrodes.

Abstract: The disclosure is of a display panel which contains a plate having two arrays of accurately dimensioned slots in which electrodes are disposed. The first array of shallow slots are formed in the plate by an etching process, and the second array of deeper slots are formed in the plate by an etching or grinding process. Electrodes are seated in the slots to form an array of rows and columns of cells.

Abstract: An apparatus and method for selectively voltage-energizing adjacent lines in a planar plasma display panel having a plurality of orthogonal gas-filled channels relative to said adjacent lines, and wherein a display is created by the selective gaseous ignition of regions in the channels between lines, ignition regions may be shifted reliably according to the teachings of the invention.

Abstract: In a plasma display panel, of a conventional type or of the planar type, a drive system consists of an array of paired, parallel drive lines, both of which may be on the same side of the enclosed gas atmosphere, as with the planar panel, or disposed on opposite sides of the enclosed gas atmosphere, and a second array, orthogonal to the first, of paired parallel write/erase trigger lines. The parallel drive lines are driven continuously with a sustain voltage drive signal. The trigger lines are selectively driven in conjunction with a selected pair of the paired drive lines to write or erase a selected display element.
