  • Patent number: 6608441
    Abstract: A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view.

  • Patent number: 6242860
    Abstract: A plasma display panel has a first substrate, a plurality of address electrodes disposed on the first substrate, a first dielectric layer disposed on the first substrate in covering relation to the address electrodes, a second substrate, a plurality of scan electrodes disposed on the second substrate in a direction transverse to the address electrodes, a second dielectric layer disposed on the second substrate in covering relation to the scan electrodes. The first substrate and the second substrate are disposed in confronting relation to each other with discharge spaces defined therebetween. The first dielectric layer contains electrically conductive particles mixed therewith. The electrically conductive particles make the first dielectric layer electrically conductive in its transverse direction to allow charges stored on the first dielectric layer to leak to the address electrodes for thereby reducing the frequency of random discharges.

  • Patent number: 4926095
    Abstract: A fluorescent gas-discharge color display panel, in which a fluorescent material is excited by a gas-discharge therein, contains a three-component gas mixture of neon, argon and xenon as the discharge gas. Typically, the argon gas component is in the range of from approximately 5 percent to approximately 80 percent, and that of the xenon gas from a minimum sufficient to maintain the Penning effect up to approximately 10 percent. The argon gas component contributes to the gas mixture producing a pure and high peak of green light spectrum and reduces the orange light spectrum emitted directly by the neon gas discharges. Other characteristics, such as operating voltages, brightness, luminous efficacy, and the panel operating life, are satisfactorily maintained. The improved color purity is advantageous for both single and multiple color display by the excited fluorescent material or materials.
