Abstract:
A display panel (10) comprises a gas-filled envelope made up of a base plate (20) and a face plate (70) sealed together hermetically. The base plate (20) is provided with a plurality of parallel, longitudinal slots (30), and an anode wire (40S, 40D) is disposed in each of the slots (30) in the base plate (20). A metal strip is wound on the base plate (20) and then cut to form an array of strip cathode electrodes (50) on the base plate (20) and oriented at an angle to the anode wires (40S, 40D), the anodes (40S, 40D) and cathodes (50) defining rows and columns of gas filled cells (58). The face plate (70) carries a series of parallel depressions (80) overlying and aligned with rows of selected ones of the cells which comprise display cells (58), and a thin film of black insulating material (90) is provided on the face plate (70) covering all but the depressions (80) in the face plate (70).
Abstract:
A display panel comprising an array of scan cells formed by an array of row scan anodes and an array of column cathodes, the scan anodes operating with the lower surfaces of the cathodes to provide cathode glow. The panel also includes an array of display cells formed by an array of row display anodes and the same cathodes, the display anodes operating with restricted areas on the top surfaces of the cathodes to provide cathode glow. The rows of display cells are offset from the rows of scan cells so thatthe glowtransfer path and display glow cell are disposed in an optimum location for panel operation and life.
Abstract:
Un panneau d'affichage comprend une enveloppe remplie de gaz et composée d'une plaque de base (20) et d'une plaque de couvercle (70) scellées hermétiquement ensemble. La plaque de base (20) est munie d'une pluralité de fentes longitudinales et parallèles (30) sur sa surface supérieure (22), de fentes verticales (32) au bord de ses extrémités, et un fil anode (40) est agencé dans chaque fente longitudinale (30) dans la plaque de base (20). Les fils sont enfoncés dans les fentes des bords et terminent attachés à des broches (44) fixées sur la surface du fond de la plaque de base (20). Des électrodes cathodiques (50) garnissent la plaque de base (20), et elles terminent également attachées à des broches (44) fixées sur la surface du fond de la plaque de base (20). Cet agencement permet de mettre des panneaux bout à bout et d'obtenir ainsi une ligne de caractères plus longue qu'avec un seul panneau.
Abstract:
Procédé de fonctionnement d'un tableau d'affichage et tableau d'affichage (10) comprenant des colonnes de cellules de balayage et d'affichage (58) qui alternent avec des colonnes de cellules de balayage uniquement (56). Les colonnes de cellules de balayage uniquement (56) sont balayées plus rapidement que les colonnes de cellules de balayage et d'affichage (58).
Abstract:
The invention can be used to build up screens intended for shared use. The inventive method for image correction consists in the following: image micro fragments are generated and spatially displaced by means of a matrix system of beamguide (8) modules (7), that makes it possible to form a continuous information field on the screen (4) projection surface. A generation and a spatial displacement of said fragments are initiated by cells (3) of a display panel. Simultaneously a dimensional scaling of macro fragments of the image is carried out by means of changing centers between the micro fragments. The screen matrix set is characterized by fact that said set comprises the matrix system of beamguide (8) modules (7), the entrance aperture thereof is embodied such that it is identical, with respect to form and dimension, to an exit aperture of the corresponding indicator cell (3) and is matched thereto. The modules (7) are formed in such a way that in each module (7) a center value between the adjacent beamguides (8), which are placed in the plane of the exit apertures thereof, differs from the center value between the corresponding cells (3). Variants for producing systems of modules by means of generating multilayer beamguides are also disclosed.
Abstract:
A flat-panel gas discharge display operable with either alternating or direct current is free of implosive forces because it operates at least at substantially atmospheric pressure. The display comprises a first set of conductors disposed on a transparent substrate and a second set crossing over the first set at a distance therefrom. An array of crosspoints is formed at each location where a conductor of the second set crosses over a conductor of the first set. A gas is contained in the space between the first and second sets of conductors at each crosspoint. The gas will undergo light emissive discharge when a voltage greater than or equal to the Paschen minimum firing voltage is applied at a crosspoint. Air may be used as the operative gas. The display is formed on a single substrate, and may be stacked with additional displays in lieu of one or more capping layers. At least one of the sets of conductors may be provided with an aperture at each of the crosspoints to facilitate viewing the discharge. A system incorporating the flat-panel display is presented. A suitably wired flat-panel structure may constitute a flat-panel plasma discharge lamp for lighting applications.

Un panneau d'affichage (10) comprend une enveloppe remplie de gaz constituée d'une plaque de base (20) et d'une plaque de face (70) scellées ensemble hermétiquement. La plaque de gaz (20) est pourvue d'une pluralité de fentes parallèles longitudinales (30) et un fil d'anode (40S, 40D) est disposé dans chacune des fente (30) de la plaque de base (20). Un réseau d'électrodes identiques en forme de languettes métalliques (68, 60, 50) sont prévues sur la plaque de base (20) en faisant un angle avec les fils d'anodes (40S, 40D) pour définir des cellules de gaz effectives (58). La première électrode en languette (68) travaille comme une anode de sauvegarde par rapport à deux électrodes auxiliaires (42, 44) logées dans des fentes (32) de la plaque de base (20), la seconde électrode en languette ou bande (60) travaille comme une cathode de remise à l'état initial, et les autres électrodes en bandes ou languettes (50) fonctionnent comme des cathodes de balayage/affichage pour le panneau (10).
Abstract:
A double-sided display panel (10) comprises a gas-filled envelope made up of a glass center plate (20) having a first face plate (70) hermetically sealed (84) to the top surface (22) thereof and a second glass face plate (72) hermetically sealed to the bottom surface (24) thereof. The center plate (20) is provided with a plurality of parallel, longitudinal slots (30, 32) in both the top and bottom surfaces (22, 24), and an anode wire (40S, 40D, 42S, 42D) is disposed in each of the slots (30, 32) in both surfaces (22, 24). A metal strip is wound on the plate and then cut to form two arrays of strip cathode electrodes (50, 52), one on each surface of the plate and oriented at an angle to the associated anode wires (40S, 40D, 42S, 42D), the anodes (40S, 40D, 42S, 42D) and cathodes (50, 52) defining rows and columns of gas-filled cells. Each face plate (70) carries a series of parallel depressions (80) overlying and aligned with rows of selected ones of the cells which comprise display cells, and a thin film of black insulating material (90, 92) is provided on each face plate (70, 72) covering all of the face plate (70, 72) but the depressions (80, 82) in the face plate (70, 72).
