The present invention relates to a plasma display board with a crossed electrode and a manufacturing technology thereof. The present invention is characterized in that the sealing point of the circumference of a display board is processed with a notch which has an outward direction and is used for filling sealing materials. An exciting electrode of the display board is connected with an electrode leading terminal arranged at the back surface of the display board through a transition electrode which is arranged outside a sealing layer, and the transition electrode and the electrode leading terminal are both made of thick film conductive coatings or thick film electrodes. The present invention has the advantages of narrow sealing width, good sealing performance, no periphery area occupation for the leading of the electrode, reliable connection for the electrode, etc. The present invention is especially suitable for being assembled into a large screen display system with a high resolution modular structure.
Description
The present invention relates to a kind of plasma display panel with crossed electrode.
Common plasma display panel is made up of two glass substrates that have exciting electrode parallel to each other, sealing all around, and the centre is filled with discharge gas, and sealant is sandwiched in around two substrates in the middle of the inner side plane.Exciting electrode extends on the base plan of sealant outside and links to each other with outside feed wire, and its typical structure such as IBM J Pes Develop rolled up contained " AC Gas Discharge Panels of 6 phases in 1978 22; Some General Considerations " literary composition is described, this display board sealant broad, the draw-out area of electrode has occupied bigger zone around the display board, therefore, is difficult to be assembled into the matrix type large screen display with high-resolution.The inventor is at Hangzhou University's journal (natural science edition) 10 phases of nineteen eighty-three contained " design of direct viewing type large screen plasma body display system " civilian described plasma display panel, adopted the method for exciting electrode being drawn from the back side, made exciting electrode draw occupied peripheral area and dwindle by transition electrode.But transition electrode adopts metal film, has certain thickness; Connection reliability between the electrode is relatively poor; Encapsulating method is not done radical change, and display board is easy to generate chronic leakage.
The object of the invention be to provide a kind of resolution height, periphery not little, the good seal performance of luminous zone width be connected reliable plasma display panel and manufacture method thereof with electrode.

Fig. 2 is a kind of seal recess structural profile synoptic diagram of the present invention, is used for illustrating embodiment 1.
Fig. 3 is an another kind of seal recess structural profile synoptic diagram of the present invention, is used for illustrating embodiment 2.
Below in conjunction with accompanying drawing the present invention is described in detail.As everyone knows, plasma display panel commonly used is by panel (1), base plate (2), panel (1) disposed inboard has palisade exciting electrode (3), base plate (2) disposed inboard has and the perpendicular palisade exciting electrode (4) of panel (1) palisade exciting electrode (3), clear glass dielectric layer (5), mixed gas layer (6) and parting bead compositions such as (7) such as neon argon.Outer rim sealing-in place that the invention reside in panel (1) and base plate (2) has direction seal recess (3) outwardly.The subtended angle of recess is 30 °-90 °, and the distance from the display board edge to the recess summit (being notch depth) is the 0.5-2.5 millimeter.The interior underfill sealants of seal recess (8).Through sintering, form peripheral sealant (9).Encapsulant is a low-melting glass.The width of sealant (9) is the 0.5-2.5 millimeter.Panel exiting electrode (3) extends on the end face of panel (1), and base plate excitating electrode (4) extends on the end face of base plate (2).At base plate (2) back side electrode leads to client (10) is set.Electrode leads to client (10) is preferably disposed on the edge at base plate (2) back side.Transition electrode (11) is placed on the outer substrate end-face of display board seal area, the one end respectively with end face on exciting electrode (3) or the overlapping 1-2 millimeter in extension of (4) join, its other end joins with electrode leads to client (11) at base plate (2) back side respectively.Base plate excitating electrode (4) also can directly extend to base plate (2) back side and electrode leads to client (10) joins.Transition electrode (11) adopts thick-film conductor coating or membrane electrode to make.For guard electrode,, form an insulating protective layer (13) at the topped one deck insulation film of the metope of display board.The structure of other parts is identical with existing plasma display panel.
Plasma display panel of the present invention with existing like product relatively has following advantage:
1, the display board sealed width is little, and electrode is drawn and do not accounted for peripheral position, thereby makes display board not below the luminous zone width reduction to 3 millimeter, and I reaches 0.5 millimeter.
2, adopt plasma display panel of the present invention can be assembled into the splice region width and only be the 1-6 millimeter, resolution is up to the direct viewing type matrix type large screen display of 100-500 line/rice.Its display area can need expansion by the user, produces easy to maintenancely, can show information such as various literal, symbol, form and figure.
3, display board good seal performance, electrode connects reliable, and manufacturing process is simple, and cost is low.
Embodiment 1, and as shown in Figure 2, getting two areas is 250 * 250 millimeters
