Abstract:
A plasma display panel in which the reliability of seal bonding of a chip tube is assured and an evacuation working efficiency is improved. In a plasma display panel with a structure in which a glass substrate on the display surface side and a glass substrate on the rear side are adhered so as to be hermetically bonded by sealing layers through partitions and a gas is introduced into the space between the two glass substrates, an evacuation and gas charging hole is formed in one of the glass substrates and crystalline glass powder of a low melting point is molded into a predetermined shape and is baked, thereby seal bonding the chip tube into the evacuation and gas introducing hole.
Abstract:
A display panel includes a resin lens layer. The display panel consists of a front panel 10 and a back panel 12 which are hermetically sealed together. The display panel also includes a plurality of display cells and is filled with a gas. A visible-light transparent resin is coated over the front surface of the front panel 10. The resin layer is raise-molded with a molding tool 16 while being solidified. Through this molding process, a resin lens layer 14 with plural lenses is formed on the front surface of the front panel 10. The resin lens layer 14 formed on the front surface of the front panel 10 can improve the brightness of the display cells.
Abstract:
An electromagnetic-wave shielding material, such as a conductive mesh member 3, is bonded to a front surface of a PDP body 20 by transparent adhesives 4B, 4C and a transparent base plate 2 is bonded to a surface of the electromagnetic-wave shielding material by transparent adhesives 4A so that they are integrated together. In this way, electromagnetic-wave shielding efficiency is imparted to a display panel itself, thereby lightening its weight, making its wall thinner, reducing the number of parts, and thus improving the productivity and reducing the cost.

Abstract:
A device for forming partition walls of a plasma display panel is disclosed. This device has a lower plate used for seating the base panel of the plasma display panel thereon, with a partition wall sheet of a predetermined thickness formed on the base panel and a plurality of electrodes arranged on the base panel. A punch, having a plurality of partition wall forming grooves and a plurality of lands formed between the partition wall forming grooves. An electrode holding groove or inclined surface is formed on each of the lands and is used for preventing the electrodes from being undesirably moved during a partition wall forming process. An upper plate is positioned above the punch so as to hold the punch and to move the punch in a vertical direction within a predetermined range. Due to the electrode holding grooves or the inclined surfaces formed on the lands, the device of this invention thus almost completely prevents an undesired movement of the printed address electrodes of the base panel, thus finally allowing a precise arrangement of the partition walls with the address electrodes on the base panel.
Abstract:
A matrix display panel of first and second substrates having respective main surfaces in parallel and opposed relationship has parallel address electrodes and respective continuous phosphor stripes arranged within corresponding elongated cavities on the main surface of the first substrate, extending in a first direction. Display electrodes on the main surface of the second substrate extend in a second, transverse direction and cross the address electrodes and respective phosphor stripes, each display electrode defining a display line of pixels. A driving system drives the panel in accordance with color image data defining successive color images to be displayed in respective, successive image frames, the color image data of each frame defining respective relative brightness gradation levels and comprising a plurality of subframes wherein lines are concurrently activated in each subframe and each subframe includes an addressing period for addressing a pixel by selectively applying a write pulse to each selected one of the pixels, the write pulse forming a memory medium in a selected one of all the pixels, a display period for lighting said addressed pixel by a concurrent application of sustain pulses to all the pixels, each subframe being allocated with a predetermined number of the sustain pulses so as to weight a gradation to said respective subframe, wherein a gradation of visual brightness of the lit pixel is determined by selectively operating the subframe for each of the pixels for each frame.
Abstract:
A light transmitting electromagnetic-wave shielding plate is provided which is formed of first and second transparent base plates and a transparent conductive film interposed therebetween. Conductive adhesive tapes A are bonded to cover a region from peripheral edges of the transparent conductive film to peripheral edges of the first transparent base plate via the end surfaces of the transparent base plate. This structure allows easy assemblage of the electromagnetic-wave shielding and light transmitting plate, and easy installation to a body of an equipment and provides uniform and low-resistant conduction between the light transmitting electromagnetic-wave shielding plate and the body.
Abstract:
The present invention provides a plasma display front panel comprising a laminate of a transparent substrate and a synthetic fiber mesh plated with a metal thereon, and offering an adequate shielding against electromagnetic waves from a plasma display. The invention employs a transparent substrate formed from a resinous composition comprising a copolymer of a monomer having an unsaturated double bond and a phosphorus-containing compound, and a copper-containing compound so as to provide a plasma display front panel featuring an excellent electromagnetic shielding performance and an ability of absorbing near-infrared rays.
Abstract:
A flat-panel gas discharge display operable with either alternating or direct current includes magnetic elements within certain of the electrodes which define the discharge cell. The display may be free of implosive forces when operated 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. The second set of conductors includes a magnetic core or layer whereby the second set of conductors is magnetically attracted to an array of contact points on the substrate. 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. A system incorporating the flat-panel display is presented.
Abstract:
A method for making a flat-panel gas discharge display is disclosed. The display is formed on a single substrate by providing a first set of conductors on the substrate, providing a second set of conductors on a supporting roll, orienting the second set of conductors at an angle relative to the first set, and affixing the second set of conductors to the substrate.
