  • Patent number: 7990056
    Abstract: A display device includes color filters and electronically aligned photo-emissive elements. The display device is achieved with a matrix of pixels. Each pixel includes a plurality of sub-pixels that are organized within the pixel in one or two directions. Each sub-pixel includes a color filter arranged facing a plurality of photo-emissive elements, an opaque area separating the color filters. In each of the organization directions of the pixel, the photo-emissive elements have a repetition pitch that is two times smaller than the pitch of the color filters. The size of each color filter is smaller than or equal to the size of the photo-emissive element in the organization direction. The display device includes a supply control circuit of the photo-emissive elements that selects the photo-emissive elements situated facing the color filter of each pixel.

  • Patent number: 7990065
    Abstract: The PDP has a front panel, and has a back panel with address electrodes formed thereon. Front panel has display electrodes including first electrodes and second electrodes formed on a front glass substrate, and a dielectric layer covering display electrodes. Further, the first electrodes and the dielectric layer include glass frit, which contains at least one of molybdenum oxide, magnesium oxide and cerium oxide, and also include a softening point exceeding 550° C. The above-described makeup suppresses a coloring phenomenon in the dielectric layer and the front glass substrate, thereby implementing a plasma display panel with a high luminance.
