  • Publication number: 20090091238
    Abstract: A light-emitting microcavity diode device includes a reflective electrode and a semi-transparent electrode, formed over a substrate, with an unpatterned light-emitting layer formed between the reflective electrode and the semi-transparent electrode. The reflective electrode, semi-transparent electrode, and unpatterned light-emitting layer form an optical cavity. Either the reflective or semi-transparent electrode is patterned to form independently-controllable, light-emitting sub-pixels. At least one, and fewer than all, of the sub-pixels emit light through a color filter. A first sub-pixel emits light having a first primary color and a second sub-pixel emits a complementary colored light. The light emitted from the first and second sub-pixels changes at one or more different angles. The color of the combined light of the first and second sub-pixels changes less at the one or more different angles than the light from at least one of the first or second sub-pixels.

    Abstract: An opaque zone in the polycrystalline (PCA) discharge vessel of a high intensity discharge lamp may be made by creating residual pores in predetermined regions of the final-sintered discharge vessel. The control over the placement of the opaque zone is achieved by forming a carbonaceous residue in a specific region of the discharge vessel prior to final sintering. During sintering, the carbonaceous material causes residual porosity in the sintered PCA. The higher emissivity of the opaque PCA provides localized cooling in order to provide more control over the condensate behavior in the discharge vessel.

  • Publication number: 20090026911
    Abstract: A lamp and methods of forming are shown. In one example, a dielectric layer is formed over a gap between conductors in a plasma lamp. Electric arcing is reduced or eliminated, thus allowing tighter gaps and/or higher voltages. In one example a glass frit method is used to apply the dielectric layer. A lamp is shown with a barrier layer that prevents tarnish such as tarnish from sulfur exposure. The barrier layer reduces or prevents degradation of the lamp due to conversion of a conductor material to non-conductive tarnish material.

  • Patent number: 7479050
    Abstract: A plasma display panel (PDP) and the method for manufacturing the same. A method for manufacturing a plasma display panel includes forming electrodes along one direction on a substrate, applying the dielectric paste along the other direction perpendicular to the one direction of the electrodes on the substrate, drying the dielectric paste and firing the dried dielectric paste to form a dielectric layer. Only one swath is needed for the entire dielectric layer, saving time and production costs, while providing a superior quality layer. Accordingly, since the dielectric paste is applied along the direction perpendicular to the longitudinal direction of the display electrodes, it is advantage that tack time and the number of cleaning the nozzle is reduced.
