  • Patent number: 8378572
    Abstract: A plasma display panel includes: a front plate; a rear plate having barrier ribs; a sealing member that seals a peripheral edge of the front plate and a peripheral edge of the rear plate; and a bonding layer that bonds at least part of the barrier ribs and the front plate to each other. The sealing member has a first glass member. The bonding layer has a second glass member. A deformation point of the second glass member is lower than a softening point of the first glass member. A softening point of the second glass member is higher than the softening point of the first glass member.

  • Patent number: 7431627
    Abstract: Address electrode patterns are formed on a rear surface glass substrate using a silver paste for forming address electrodes, and these patterns are dried. The average particle size of the silver powder in the silver paste is approximately 10 nm, and the softening point of the glass frit is approximately 420° C. The content ratio of the glass frit in the silver paste is set to 5 wt %. Then, a dielectric layer pattern is formed by using glass paste for forming a white dielectric layer so as to cover the address electrode patterns, and this dielectric layer pattern is dried. The glass frit in the glass paste has a softening point of approximately 540° C. Then, the address electrode patterns and the dielectric layer patterns are baked at a temperature of 540° C. Thus, the resin components in the address electrode patterns and the dielectric layer pattern are burnt away, and the glass frit components are softened so as to be fixed onto the rear surface glass substrate.

  • Publication number: 20070278955
    Abstract: A manufacturing method of a PDP includes: a first material filling step for filling recessed portions (41) of a molding die (4) with a first dielectric paste (23A) that forms partitions; a second material application step for applying a second dielectric paste (22A) that forms an address electrode protective layer on a rear substrate (2); a transfer step for pressing the molding die (4) against the second dielectric paste (22A) and then peeling the molding die (4) off from the rear substrate (2); and a firing step. Since the molding die (4) is pressed against the second dielectric paste (22A) that has a fluidity in the transfer step, the first dielectric paste (23A) and the second dielectric paste (22A) can be adhered to each other securely. Accordingly, the partitions having a desired shape can be formed securely and inter-partition portions of the address electrode protective layer can be uniformly formed with a uniform thickness.

  • Patent number: 6232717
    Abstract: In an AC type surface discharge color plasma display panel which includes transparent electrodes (2) formed on a first substrate surface of a first substrate (1), bus electrodes (3) formed on the transparent electrodes, respectively, first, second, and third color filter layers (4R, 4G, and 4B), and a transparent dielectric layer (5) covering the transparent electrodes, the bus electrodes, and the color filter layers, each of the first, the second, and the third color filter layers and each of the bus electrodes are located offset from each other on the first substrate surface so as not to overlap each other and so as not to be brought into contact with each other. The transparent electrodes are substantially parallel to each other. The bus electrodes are substantially parallel to each other and to the transparent electrodes.

  • Patent number: 4716341
    Abstract: A display device which is driven by a high driving voltage, has a display panel with display electrodes. A conductor line extends along the surface of the display panel. A high voltage producing means is connected to one end of the conductor line for applying a high voltage to the display electrodes. A low voltage source is connected to the other end of the conductor line for operating the high voltage producing means. Thus, an application of the high voltage to the display electrodes is terminated when the conductor line is broken or cut as a result of damage to the display panel.

  • Patent number: 4613794
    Abstract: A charge transfer plasma display device includes plural transfer electrodes arranged in an alternating fashion on opposite walls of a plasma-filled enclosure, so that the electrodes on one wall are interlaced between those on the other wall. Plural groups of write electrodes are disposed at one end of the transfer electrode arrangement, with each write electrode in each group being connected in parallel with an associated write electrode in every other group. Disposed between the write electrodes and the transfer electrodes are plural input shift electrodes. The input shift electrodes have different lengths so that a different number of such electrodes are disposed between each group of write electrodes and the transfer electrodes. In operation, the input shift and transfer electrodes are successively energized in a continuing sequence, and the write electrodes are selectively energized, in coordination with the energization of the shift electrodes, to create "pips" of light.
