An front plate structure for a plasma display panel is described. In accordance with the present invention, a protruding space pad structure is formed on the dielectric layer or protective layer of the front plate. The space pad is used to form the height difference on the surface of the front plate, about 3 μm to 15 μm. The height difference forms gas channels between the front plate and the discharge region to improve the performance of the vacuuming and refilling gas steps.

A method for forming a vent port in a glass panel and a glass panel product manufactured using the same. The vent port has no protruding vent pipe, such that the vent port discharging gas from a sealed space to the outside is formed in either one of a pair of plate glasses separated in a thickness-direction to form the sealed space therebetween, produced by: forming an exhaust hole in either one of the plate glasses; vertically inserting a vent-pipe-type sealing material into the upper portion of the exhaust hole; discharging gas from a space between the plate glasses to the outside; heating the sealant member such that the sealing material is converted into fluid and the exhaust hole is closed by the sealing material having collapsed after being heated; and solidifying the sealing material remaining in the exhaust hole, ensuring good sealing properties without using a protruding vent pipe.

A pressure compensating device for a plasma display panel expands from an unextended position at lower altitudes to an expanded position at high altitudes to maintain the pressure differential across the panel sidewalls within predetermined limits. One embodiment includes a bellows assembly positioned on the rear wall of the plasma panel. The end wall of the bellows contacts an internal stop at lower altitudes so that the volume inside the bellows is as small as possible. As the pressure differential across the panel sidewall increases, either as a result of changes in the ambient temperature or pressure, the bellows moves in an axial direction to its extended position providing an additional volume in which the panel gas is received. Accordingly, the pressure differential across the panel sidewall can be maintained below a certain predetermined level irregardless of changes in ambient pressures and temperatures.

A flat display panel has a ventilation hole formed in a back glass substrate facing a front glass substrate with a space in between, and provides communication between the space and the exterior. A ventilation duct is connected to the ventilation hole and secured with a pressed frit to the outer face of the back glass substrate. The ventilation duct has a flange formed at one end thereof connected with the back glass substrate. The pressed frit having a ventilation hole is sandwiched between the flange and the back glass substrate, and fused to the flange and the back glass substrate in order for the ventilation duct to be secured to the back glass substrate.
摘要:
In the manufacture of a gas discharge type display panel, by applying a sealing operation along with an exhausting operation, the sealing glass 14 is broken down by a pressure difference between the inside and outside of the panel, and thus, the clearance gap between the substrates can be controlled as desired. In addition, the gaseous component that is unnecessary for the discharge operation is exhausted by setting the temperature of the amorphous sealing glass to exceed its softening-point and be no more than its working point. In the structure of the gas discharge type display panel, a protruding portion having a radius of curvature between 0.1 mm and 1 mm is formed on the sealing glass to reduce the dispersion in the thickness direction of the sealing glass, or the cross-sectional shape of the sealing glass is made convex both at its inside end part and its outside end part.
摘要:
A gas discharge image display is formed by disposing a plurality of fluorescent lamps 1 each comprising a glass bulb 2 within which a rare gas is sealed, one or more pairs of external electrodes 5a and 5b located on the outer wall of the glass bulb 2, and a fluorescent layer 3 formed on the inner wall of the container facing the external electrodes 5a and 5b. An alternating voltage pulse is applied between the paired external electrodes 5a and 5b by an X drive circuit 9 and a Y drive circuit 10 for discharge light emission, thereby displaying an image. The pressure and alternating voltage in the fluorescent lamp 1 are changed in response to the type of fluorescent material, thereby making near light emission and discharge characteristics of the discharge lamps which differ in electric characteristics.

摘要:
Front substrate and back substrate of a PDP are respectively in a warped state such that a central portion of each substrate projects more frontwards than peripheral portions of the respective substrate, so that the front surface is convex. A stress remains in the substrates such that the two substrates are pressed to each other with an elastic deformation. In preparing the two substrates, the front panel and back panel are respectively warped towards each other so that the facing inner surfaces are convex in being sealed with each other. A height difference ratio of the central portion from a central part of a short side of the back substrate is preferably less than 0.16%. A height difference ratio of the central portion from a central part of a short side of the front substrate is preferably less than 0.06%. Difference of the height difference ratios of the back substrate and the front substrate is preferably 0 to 0.1 point.

Disclosed is a plasma display panel including a porous metal plate in which a plurality of holes for display cells are formed at positions corresponding to intersections at which a first linear electrode group and a second linear electrode group cross each other with a predetermined interval therebetween, and a front glass plate, wherein openings of the holes of the porous metal plate on the front surface side are larger than openings on the rear surface side, the openings on the rear surface are covered with a molten material of an inorganic dielectric containing glass and are thereby air-tightly sealed. This plasma display panel is light in weight and thin and can be easily assembled.
