Abstract:
A flat display panel and a flat display device are realized in which sealing layers can sufficiently alleviate and absorb strain stress between two substrates which is caused by internal stress of the substrates during sealing process and after cooling process, and which can cancel out disadvantages of an amorphous glass paste and a crystallized glass paste, and a flat display panel manufacturing method is realized which can prevent application of excessive or insufficient pressure to the sealing layers. In a flat display panel formed with at least two substrates (1A) and (1B) sealed together, sealing layers (21a) are formed as a stacked structure containing a plurality of layers or formed in a region containing a plurality of stripes, so as to obtain a stable seal. The sealing layers (21a) are formed of a crystallized glass paste (2A) and an amorphous glass paste (2B). A pressing force applied in the sealing process is positioned near the sealing layers and inside the position of the sealing layers.
Abstract:
The disclosure teaches using at least two orthogonal arrays of complicated shaped glass rods or very large fibers-like structures (from here in referred to as fibers) with wire electrodes to fabricate plasma displays with plasma cells larger than 0.05 mm3 in volume. (The volume of a plasma cell is defined by the width of the plasma channel times the height of the plasma channel times the pitch of the pair of sustain electrodes.) To increase the size of the bottom fiber and keep the addressing voltage constant or to reduce the addressing voltage, the address electrode is moved from the bottom of the channel up into the barrier rib. Moving the address electrode up into the barrier rib will reduce the distance, d, between the address electrode and the sustain electrodes, thus increasing the electric field of the addressing pulse. To maintain a more uniform addressing field and build redundancy into the display an additional address electrode can be included in the barrier rib wall on the other side of the plasma channel.
Abstract:
A plasma display having a transparent front panel spaced from a back panel which is a metal core having layers of a dielectric material extending over and bonded to the core. Conductive electrodes are on the surface of or imbedded in the dielectric layer of the back panel. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. The dielectric material is made from a green ceramic tape which is bonded to the core and cofired with the core to form the back panel. Barrier ribs are formed on the back panel by embossing or scribing the green tape before cofiring the bonded assembly. Slight differences in the TCEs of the front and back panels may be compensated for by heating the panel having the lower TCE to a temperature hotter than the panel having the lower TCE during the frit seal process. Alternatively, the materials for the dielectric may be chosen such that the composite TCE of the cofired assembly matches the TCE of the front panel.
Abstract:
A plurality of scanning electrodes and a plurality of sustaining electrodes parallel to each other are located on an inner face of a first glass substrate. Each of the scanning electrodes and each of the sustaining electrodes form a pair. A dielectric layer and a protection layer are formed on the first glass substrate in this order, covering the electrodes. A plurality of data electrodes perpendicular to the scanning electrodes and the sustaining electrodes are located on an inner face of a second glass substrate which is located opposed to the first glass substrate with a discharge space interposed therebetween. In an AC-type PDP having such a structure, at least one of the plurality of scanning electrodes and the plurality of sustaining electrodes are divided into a plurality of groups, and pulses having different phases are applied to the electrodes in different groups, thereby causing sustaining discharge. The scanning electrodes and the sustaining electrodes may be comb-like with teeth. The comb-like scanning electrodes and the comb-like sustaining electrodes are opposed to each other with a small gap interposed therebetween in the manner that the teeth thereof are in engagement with each other. In such a case, the data electrodes are located opposed to and in a longitudinal direction of the teeth of the scanning electrodes.

Abstract:
A flat-panel gas discharge display operable with either alternating or direct current is free of implosive forces because it operates 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. 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, and may be stacked with additional displays in lieu of one or more capping layers. At least one of the sets of conductors may be provided with an aperture at each of the crosspoints to facilitate viewing the discharge. A system incorporating the flat-panel display is presented. A suitably wired flat-panel structure may constitute a flat-panel plasma discharge lamp for lighting applications.
