The present invention relates to an improved assembly structure of a display panel in a display device of the same type as a flat panel display device, for example, a plasma discharge display device configured to display necessary matrices on a front panel using plasma discharge electrodes arranged in a dot matrix manner. will be.

BACKGROUND OF THE INVENTION A display apparatus of this kind generally includes a front plate on which a plurality of parallel transverse electrodes (anode electrodes) are formed, and a base crate on which a plurality of parallel longitudinal electrodes (cathode electrodes) are formed. The display panel has a display panel formed by assembling and fastening the electrodes on each plate so that the electrodes on each plate vertically cross each other at a desired position. In the related art, the front plate and the base clay may be used when the display panel is assembled. A separate and expensive clamp means was required to hold the clamp stably in a certain position so that accurate assembly of the panel was possible. Relative position is misaligned Since it is easy, there was a problem such as a very high incidence of defects.

The present invention is a new and useful display panel assembly structure devised to solve such a conventional problem very effectively, the specific technical details and effects will be described in detail based on the accompanying drawings.

1 is an exploded cross-sectional view showing an enlarged excerpt of a main portion of a flat panel display panel having an assembly structure according to the present invention, wherein 1 is a front plate of the panel, 3 is a transverse electrode formed on the front plate 1, 2 denotes a base plate, 4 denotes a vertical electrode or the like formed on the base plate 2, respectively.

The electrodes (3) and (4) are formed by mixing powders such as lead glass, electrode material, and the like with a known chemical substance at a desired thickness on the plates (1) and (2). Repeated printing with the width is formed into electrodes 3 and 4 of the required height, followed by sintering and completion.

The present invention, when printing the electrode (3) (4) formed on the plate (1) (2) in the blank area where the electrode is not formed in the electrode forming surfaces on these plate (1) (2), The assembly position guide structure (5) (6) which can correspond to each other in the desired assembly position between the plates (1) (2) to form a few pieces, and thus the electrodes (3) (4) and the assembly position guide Assemble the plates 1, 2 on which the structures 5, 6 are respectively formed so that the structures 5 on one plate 1 coincide with the corresponding structures 6 on the other plate 2. It is characterized by that.

The structures (5) (6) on each plate (1) (2) are each formed on the front plate (1) and the base plate (2) in the form as shown in Figs. At least two of the surfaces face each other, and these structures (5) and (6) are formed by printing the electrodes (3) and (4) onto each plate (1) and (2). The same material can be used to simultaneously print the copper electrodes. Herein, any one of the pairs of structures 5 and 6 corresponding to each other, such as the structure 6, is to achieve a height higher than the corresponding electrodes 4, which is required for its assembly position guiding action. Additional printing may be performed for this purpose.

The present invention has several sets of additionally simple printings that can be additionally formed with these electrodes when printing the electrodes 3 and 4 on the front plate 1 and base plate 2 constituting the display panel. Assembling position guide structures (5) (6) by using the plate (1) (2) can be easily and accurately assembled without error, so that each plate (1) (2) in a certain position as in the conventional assembly There is a separate clamp means that can hold and support and has an excellent effect that can greatly improve the manufacturability and quality of such a display panel by minimizing the occurrence of assembly defects without requiring a high working skill and attention.

Claims (2)

In a display panel in which the front plate 1 having the transverse electrodes 3 and the longitudinal electrodes 4 are composed of a base plate 2, the electrodes 3, 4 of the plates 1, 2 are At least two sets of assembly position guide structures (5) (6) corresponding to each other at a desired assembly position between the plates (1) and (2) are formed on a margin where no electrodes of the surfaces to be formed are formed. A panel assembly structure of a flat panel display device. The electrode (3) (4) according to claim 1, wherein the assembly position guide structures (5) (6) form an electrode (3) (4) on the front plate (1) and the base plate (2). Panel assembly structure of a flat panel display device characterized in that they are structures formed simultaneously with these electrodes (3) (4) using the same material.
