Abstract

PURPOSE:To stably connect a flat cable without sliding it sideways by arranging connecting terminal patterns reticulately. CONSTITUTION:Each of connecting terminals 35 connected to an electrode group 31 is formed and arranged, for example, in parallel-crosses-type meshes pattern form without increasing the terminal pattern form. Such a connecting terminal pattern can be formed simultaneously when the electrode group is formed with a thick coat by the screen printing method. The sectional shape of the respective connecting terminals 35 becomes flat as a whole and the contact section for flat cables to be connected is increased and then the resistance for sliding (strike slip) is increased. As a result, when the flat cable is connected by a crimp clip or soldering, the possibility of cable connection sliding is prevented from occurring and the cable can stably and easily be connected.

Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to flat display panels, and in particular to improvements in the arrangement structure of electrode connection terminals formed by thick films in high resolution display panels that utilize gas discharge. (1)) Technical background A type of flat sludge discharge display panel, generally known as a plasma display panel, is known as a tontomatolinx type scum discharge display panel. In recent years, in order to improve display density and display quality, display dot pinch has been reduced and resolution has been increased. However, as the dot pitch of one display panel is made finer, the arrangement pitch of the FE interconnects and IM elements of the electrodes for dot display also becomes smaller, which causes problems such as making the connection with the driving peripheral circuitry complicated.

(C) Prior art and problems Figure 1 is a diagram for explaining a conventional dot matrix type gas discharge display panel. A pair of electrode-constituting substrates 3 and 4 having a set of X electrode groups L, ! : Y electrode group 2 are arranged facing each other so as to be orthogonal to each other, and these 1
The same sides of the pair of electrode constituent substrates 3 and 4 are sealed with low-melting glass 5.

After the space gap is once evacuated to a vacuum, predetermined discharge scum is sealed within the space gap. [7] Each connection terminal group IP of both electrode groups 1 and 2 of the display panel,
l b and 2a, 2bK drive Il! In order to connect to the peripheral circuit, for example, a flat goofle (not shown) in which a large number of conductive wires are integrally formed in parallel with a resin covering material is connected using crimp clips or solder hooks, etc.
The driving peripheral circuit selectively applies a 9f voltage between the electrodes of the two electrode groups 1 and 2 of the display panel to generate a discharge at the opposing intersection of the two electrodes.
The dot display is carried out by

By the way, when constructing a high-resolution cass discharge display panel by reducing the pinch of display dots in the cass discharge display panel having the above configuration, the rAAIillJli:if side circuit (!-the xi! pole group 1 and The arrangement pinch of each connection terminal group 1a, lb and 2a, 2b of electrode group 2 is inevitably small, and the width of each connection terminal itself is also reduced accordingly, and the connection with the 7 rung group 7 is shifted. 1, especially the X electrode group 1 and the X electrode group 2
．． In addition, in the case where the connection terminals connected thereto are formed of a thick film by screen printing, as shown in the partial cross-sectional view of FIG. The cross-sectional shape of each electrode connection terminal 22 is semicircular, and the contact with the 1.7-rat cable is rk.
The I product becomes smaller. Therefore, when a flat cable is connected to each connection terminal f, the flat cable tends to slide sideways, and the seven-rat cable is connected sideways to the connection terminal f. .

(d) Object of the Invention In order to overcome the above-mentioned conventional drawbacks, the present invention provides a method without significantly changing the shape of the electrode connection terminal provided on the panel component substrate to which the flat couple is to be connected.

It is an object of the present invention to provide a new flat display panel which increases the contact with the flat panel and has a structure that prevents skidding, and which allows stable connection L-4P without causing the 7"-full to shift laterally. This is the purpose.

(e) Structure of the Invention According to the present invention, a pair of panel-constituting substrates, at least one of which supports a plurality of electrodes with a surface of fat K, is provided. In a panel configuration in which the panels are arranged facing each other with a fixed fil gap, the upper &! This is achieved by providing a flat display panel characterized in that connection terminal patterns of a plurality of electrodes are arranged in a mesh pattern.

1 and the X electrode group (not shown), if the terminal pattern shape is enlarged (!-), for example, each connection terminal 35 connected to the X electrode group (not shown) is formed and arranged in a cross-shaped mesh pattern shape. Such a connection terminal pattern is as follows. Each electrode group can be formed simultaneously when forming a thick film using a screen printing method.In this way, each connection terminal 35 is connected to #:l
By forming it into a [fl-cutter] shape, each of the connection terminals 350#'
The r m+ shape is generally flat, the contact area with the connecting seven-rat cable increases, and the resistance to slipping (t112 deviation) increases. Therefore, when connecting a 7-runt cable to a high-resolution cass discharge display panel equipped with such electrode connection terminals by crimping, crimping, or weekday wire transfer, the risk of connection misalignment as in the conventional method is eliminated, and the connection is stable and stable. Connections can be made easily.

In addition, we will discuss the above embodiment (1) in which one pattern of the electrode connection terminal is formed into a cross-shaped mesh pattern.

(g) It is clear from the explanation that the effect of the invention is more The installed chairs are L
Therefore, even if the hinge for the connection work is made smaller and the terminal width is reduced, the cross-sectional shape of the connection terminal will not become a semi-cylindrical shape as in the past.

As a whole, the surface becomes flat, the contact area with respect to the seven-rat couple to be connected increases, and the resistance against slipping (lateral displacement) K also increases. Therefore, when connecting flat cables with crimp clips, soldering, etc., there is no possibility of connection deviations occurring as in the conventional method, and there is an advantage that the connection work can be performed easily and stably.
