Description
Technical field
The utility model relates to a kind of plasma panel, especially relates to a kind of assembled plasma phanel.
Background technology
Existing plasma panel is bonded together by two glass substrates that are parallel to each other in front and back; be provided with horizontal transparency electrode of X and the vertical addressing electrode of Y at the glass substrate medial surface; cover one deck insulating medium layer and protective layer on the front glass substrate electrode; on the glass substrate electrode of back except that covering one deck insulating medium layer and protective layer; also scribble red; blue; green three-color phosphor and barrier layer; horizontal transparency electrode of X and the orthogonal thereto setting of the vertical addressing electrode of Y; seal with glass powder with low melting point all around; cavity that is filled with gas of middle formation; horizontal transparency electrode of X and the vertical addressing electrode of Y are drawn to the glass substrate outward flange by sealing strip all around, before extraction electrode is distributed in; the both sides of back glass substrate.A kind of AC plasma display screen is disclosed in the Chinese patent patent application prospectus that September 26 calendar year 2001, disclosed publication number was CN1314693A; comprise front glass panel and back glass plate; front glass panel is made of transparency glass plate, transparency electrode, dielectric layer and medium protective layer, and back glass plate is made of glass plate, addressing electrode, dielectric layer, barrier, phosphor powder layer.With front glass panel and back glass plate with frit seal together, through exhaust, charge into the inertia discharge gas, encapsulation at last constitutes plasma panel.Wherein when carrying out the encapsulation of front and back glass plate, must elder generation be coated with the encapsulating material that is constituted by silicon dioxide (SiO2), lead oxide (PbO) and boron oxide (B2O3) at the ad-hoc location of front glass substrate and back glass substrate desire encapsulation place, with about 400～450 ℃ high-temperature process, front glass substrate and back glass substrate are bonded together again.Yet, adopt this method for packing, the one, it is cumbersome on technology aspect width and the THICKNESS CONTROL that package material is sealed in coating in advance up for safekeeping, the 2nd, front glass substrate and back glass substrate be stitched together heat when encapsulation, can cause the variation of encapsulation hem width degree during the encapsulating material fusing, and then non-luminous frame size all around of plasma panel is increased, generally at 10 millimeters～15 millimeters, cause large-screen to have tangible window frame sense with this plasma panel assembly unit, have a strong impact on the display effect of large screen plasma display screen, limited its application greatly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of assembled plasma phanel with narrow encapsulation limit.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it comprises front glass substrate and the back glass substrate that is parallel to each other; be provided with transparency electrode at front glass substrate; dielectric layer and protective layer; back glass substrate is provided with addressing electrode; dielectric layer and barrier; in the cavity of adjacent barrier, deposit fluorescent material; between front glass substrate and back glass substrate, be filled with gas; bond them together by encapsulant; it is characterized in that: the seam crossing around described front glass substrate and the glass substrate side, described back has opening groove outwardly, and described encapsulant pointing is in described groove.
The cross sectional shape of described groove can be inner small and outside big trapezoidal, half garden shape, rectangle.
The degree of depth of described groove can be 0.05 millimeter～2.0 millimeters, and A/F can be 0.05 millimeter～0.5 millimeter.
Described groove can also be the medial surface fluting at described front glass substrate, and makes the size of described back glass substrate littler 0.3～1.5 millimeter than the size of described front glass substrate.
Compared with prior art, advantage of the present utility model is that the seam crossing around front glass substrate and the glass substrate side, back has opening groove outwardly, can earlier glass substrate be fit together, then with the encapsulant pointing in groove, after heating the encapsulation; So not only technology is simple, and utilizes the distortion after the physical dimension of groove limits the filler heating, make plasma panel around non-luminous frame size restrictions in a small range.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment is 1.: as Fig. 1; Fig. 2; shown in Figure 3; a kind of assembled plasma phanel; comprise the front glass substrate 1 and the back glass substrate 2 that are parallel to each other; be provided with transparency electrode 4 at front glass substrate 1; transparent dielectric layer 5 and protective layer 6; back glass substrate 2 is provided with addressing electrode 7; addressing dielectric layer 8 and barrier 9; in the cavity 11 of adjacent barrier, deposit fluorescent material 10; between front glass substrate 1 and back glass substrate 2, be filled with gas; seam crossing around front glass substrate 1 and glass substrate 2 sides, back has opening groove 12 outwardly; encapsulant 3 pointings are gone in the groove 12; by 400～450 ℃ high temperature encapsulant 3 being heated makes its fusing, with front glass substrate 1 and back glass substrate 2 bonding being packaged together.The cross sectional shape of groove can be set to inner small and outside big trapezoidal, and section depth is 0.05 millimeter～2.0 millimeters, and the long hem width degree in cross section is 0.05 millimeter～0.5 millimeter.
