Abstract:
The present invention relates to a plasma display panel and method of manufacturing the same. In accordance with the present invention, in a process of forming a sealant on one of an upper substrate and a lower substrate from a first point to a second point, the sealant of the first point and the sealant of the second point are separated apart from each other, and the upper substrate and the lower substrate are then coalesced. Therefore, since an area where the sealants are overlapped with each other can be reduced, the sealants can be formed to have a uniform height. It is thus possible to completely seal the upper substrate and the lower substrate.
Abstract:
An AC plasma display panel has a pair of panels disposed in spaced opposed relation, and each having a plurality of electrodes formed on an opposed surface thereof and mostly covered with a dielectric layer; and a sealing member which seals the periphery of the pair of panels. The electrodes each have a portion uncovered with the dielectric layer, and the sealing member is disposed in contact with the uncovered portions of the electrodes. With this arrangement, the discharge space can be kept gas-tightly sealed by the sealing member without communication with the outside of the display panel which may otherwise occur due to the presence of voids on opposite sides and surfaces of the electrodes.
Abstract:
Barrier ribs 18 formed on a back substrate PA2 are brought into contact with a bonding paste layer 40 having an even surface, applying a bonding agent Bd evenly to the tops of the barrier ribs.Furthermore, a gas discharge panel having a structure in which discharge mainly occurs at locations distanced from parts of the panel connected using the bonding agent Bd is realized.
Abstract:
A display electrode and a dielectric layer are formed on the convex side of a front glass substrate that is convexly curved in profile, whereas address electrodes, a dielectric layer, partition walls and phosphor layers are formed on the convex side of a back glass substrate 15 that convexly curved in profile. Further, a sealing layer containing granular substances in a sealing material is formed in the peripheral portion of the back glass substrate. A front panel and a back panel are stacked so that the panel component parts of the front panel are set opposite to the panel component parts of the back panel. Then the peripheral portions of the panels are pressed against each other into a flat substrate plate as shown by arrows and heated up.
Abstract:
A plasma display panel for multi-screen system comprising a front and a back dielectric plates; transparent and addressing electrodes orthogonally located between the plates; display cells defined by the mutually orthogonal electrodes; barrier ribs for separating and defining display cells from each other; and a very narrow sealing seam for sealing edge parts of the two plates. The sealing seam has a width ranging from about 0.3 mm to about 1.5 mm. The sealing material is a glass powder having a special composition that enables a low melting point. A concave groove accommodates the sealing material. The present invention prevents the image from missing between the adjacent units in the display matrix and eliminates the dark matrix border lines.
Abstract:
A seal plate is installed for sealing tightly an exhaust hole provided to a glass substrate of the back side of a PDP (flat display panel). The air is directly exhausted from internal spaces via the exhaust hole and gas is sealed into an enclosure. The seal plate is heat-secured to the exhaust hole so as to seal the internal spaces tightly.
Abstract:
A plasma display panel reduces noise caused by the formation of minute gaps between the first substrate and the second substrate. The plasma display panel includes a first substrate and a second substrate opposing one another with a predetermined gap therebetween, and a sealant formed on opposing surfaces of the first substrate and the second substrate. The sealant is formed around outer circumferential areas of the first substrate and the second substrate to seal the first substrate and the second substrate together. The sealant is formed of regions having a first width of substantially the same size and of regions having a second width greater than the size of the first width.
Abstract:
A plasma display panel is provided in which an operational quality is prevented from being deteriorated by resonance of a substrate. The plasma display panel includes a partition for dividing a discharge gas space defined by a pair of substrates and a sealing material in accordance with a cell arrangement of a display screen. There is a void space between the upper surface of the end portion of the partition and the surface of the opposed substrate, the surfaces contacting each other. The natural frequency of the portion from the inner edge of the void space to the inner edge of the sealing material is raised above audio frequency region of a human.
Abstract:
A sealing area of a flat display is provided. The sealing area includes front and rear substrates provided to be opposed to each other, which are sealed to each other using frit glass so as to form a discharge space, an evacuation pipe sealed to the outer surface of the rear substrate using frit glass, and a moisture-resistant coating layer formed on the surface of the frit glass.
Abstract:
A gas-discharge display panel is manufactured by sealing up a front substrate and a rear substrate by a sealing member. A relationship of TgnullTf exists between a glass transition point Tg of a dielectric substance formed on the front substrate and a temperature Tf at which the front substrate and the rear substrate are sealed up.
