Abstract

PURPOSE:To obtain a case with high reliability of maintained hard vacuum and electric connection by installing electrode terminals across the staged section of a bottom case to lead out the terminals through conductive thin films and then sticking a case piece with a reversed stage to the bottom case to fix the terminals between the case piece and the bottom case. CONSTITUTION:The inner surface of a bottom case 5 is provided with a stage 6 which supports the electrode. Conductive thin films 7 are formed corresponding to lead-out electrode terminals 8 by vapordeposition, printing or other means in a strip-like form so that the terminals 8 can be led outside. Then, conductive paths are formed between the electrode terminals 8 and the lead-out thin films 7 by means of a conductive adhesive. Next, after a case piece 9 with a reversed stage is placed over a bottom case 5, the terminals 8 are pressed and fixed to conductive thin films 7 and the conduction of the terminals 8 are confirmed. After that, an upper case is fused to the case piece 9, thereby completing a whole case.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum container used in a flat-screen television receiver.

Structure of the conventional example and its problems The conventional image display device has a built-in electrode 1 as shown in FIG.
It was common practice to stack the upper and lower container pieces 2.3 on top of each other, glue them together, and take them out from the side of the container at right angles as shown in B.

However, as shown in B, (1) the terminal 1 is taken out perpendicularly to the side, thereby increasing the volume (relative to the effective area of the screen).

■ Since the terminal 1 is sandwiched between the adhesive surfaces of the containers 2 and 3, the reliability of maintaining the vacuum level is not good.

■ Mounting becomes complicated when connecting the gold molded electrode terminal 1 to the cutting circuit.

There is a drawback. but ■ Easily hold the electrode inside.

■ Easy to assemble.

There are some places where this is true.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a vacuum container which improves the above-mentioned drawbacks, requires a small unnecessary area, and has high reliability in maintaining the degree of vacuum and making connections for drowsiness.

Structure of the Invention In the present invention, a low level difference is provided on the inside of the bottom container. Apply a conductive thin film from the inside to the outside of the bottom container according to the electrode extraction position 1 - Pass the electrode terminal across the step, take out the electrode terminal to the outside through the conductive thin film, and remove the step opposite to the step of the bottom container. The attached container piece is glued to the bottom container, and at the same time, the electrode terminal is fixed between the sub-containers.

EXAMPLE 7 An example of the present invention will be described below with reference to second F21A, B, and C.

In this embodiment, a step 6 is provided on the inside of the bottom container 5 to support the electrode and correspond to the position of the takeout terminal. Then, a conductive thin film 7 (for example, indium oxide or tin oxide) is coated from the inside to the outside by vapor deposition, printing, or other means.
11 stripes are formed so that kPj can be extracted. Then, a conductive path is formed between the electrode terminal 8 and the lead-out thin film by contact and a conductive adhesive (silver paste). However, this method lacks reliability in terms of support and conduction, so as shown in FIG. 2C, the container piece 9 is placed on the bottom container 5 and fixed by frit bonding. And terminal 8
While holding down the
2 is sealed on top to form the entire δ vessel.

Effects of the Invention As described above, according to the present invention, the sealing surfaces of the three container pieces can be improved by a large amount by changing the flatness, and the wiring for taking out can be omitted in terms of mounting, thereby obtaining a useful vacuum container. It is something that can be done.
