Problems solved by technology

Therefore, in terms of separation between the screen and the base member, it is first necessary to crush the screen and remove the glass piece from the base member little by little with a scraper or the like, so the separation work is very time-consuming and cumbersome.

no. 1 approach

[0029] Next, a method of manufacturing the plasma display device according to the first embodiment will be described with reference to FIGS. 1 to 8 . However, embodiments of the present invention are not limited thereto.

[0030] FIG. 1 shows the configuration of a screen of a plasma display device according to a first embodiment of the present invention. As shown in FIG. 1 , on a transparent front-side substrate 1 such as a glass substrate, a plurality of rows of stripe-shaped display electrodes 2 are formed, in which scan electrodes and sustain electrodes form a pair. Furthermore, a dielectric layer 3 is formed to cover the electrode group, and a protective film 4 is formed on the dielectric layer 3 .

[0031] In addition, on the back side substrate 5 disposed opposite to the front side substrate 1 , a plurality of rows of strip-shaped data electrodes 7 covered by the coating layer 6 are formed so as to intersect with the display electrodes 2 of the scan electrodes and the ...

no. 2 approach

[0056] Next, a second embodiment of the present invention will be described. 9 is a cross-sectional view in a direction perpendicular to adhesive material 17 of the plasma display device according to the second embodiment. FIG. 10 is a plan view showing the application shape of the adhesive material 17 .

[0057] As shown in Fig. 9 and Fig. 10, for the adhesive material 17, the width on the side of the peeling start point 17A is wider, and the width gradually becomes narrower from the peeling start point 17A to the peeling end point 17B. Instead, it is coated and arranged between the screen 10 and the bottom plate member 14 . In addition, the rectangular adhesive materials 17 are arranged so that the peeling start points 17A of the adhesive materials 17 are alternately located on opposite sides of the bottom plate member 14 . That is, as shown in FIG. 10 , the rectangular adhesive materials 17 are arranged such that the intervals between them are substantially constant and u...

no. 3 approach

[0064] Next, a third embodiment of the present invention will be described. 12 is a cross-sectional view in a direction perpendicular to adhesive material 17 of the plasma display device according to the third embodiment. FIG. 13 is a plan view showing the application shape of the adhesive material 17 .

[0065] As shown in FIGS. 12 and 13 , the adhesive materials 17 are arranged in a plurality of rows at predetermined intervals between the screen 10 and the bottom plate member 14 . Furthermore, a plurality of spacers 21 for defining a gap between the screen 10 and the bottom plate member 14 are arranged between the plurality of rectangular adhesive materials 17 . The spacer 21 is configured by arranging a stretch-peelable adhesive 21A in an island shape, and embedding beads 21B such as glass beads or resin beads in the island-shaped adhesive 21A.

[0066] In addition, the rectangular adhesive material 17 is desirably arranged so that a part of it protrudes from between the ...

Abstract

The invention provides a manufacturing method for a plasma display device which can be easily used to separate a screen from a holding panel. The manufacturing method of the plasma display device is that: in the plasma display device comprising the screen and backplane components made of metal, heat conductive components are formed by extensive peeling type adhesive materials, after the screen or the holding panel are coated with the adhesive materials, the screen and the holding panel are superposed, and the adhesive materials are solidified by pressing and heating, wherein, the screen relatively arranges a pair of substrates with at least one transparent front side by a mode of forming a discharge space between the substrates, and is provided with a plurality of discharge units; the backplane components made of metal maintain the screen through the heat conductive components.

Description

technical field [0001] The present invention relates to a method of manufacturing a plasma display device known as a large-screen, thin, and lightweight display device. Background technique [0002] In recent years, plasma display devices have attracted attention as display screens (thin displays) with excellent visibility, and their high definition and large screen size are progressing. [0003] According to the driving method, the plasma display device is mainly divided into AC type and DC type, and according to the discharge method, it is mainly divided into surface discharge type and opposite discharge type. At the present stage, AC type surface discharge type plasma display devices occupy the mainstream. [0004] In such a plasma display device, a double-sided adhesive material made of acrylic, polyurethane, or silicon-based materials is used, or a heat-conducting sheet is used to fix the screen and the bottom plate components whose main material is glass. Aluminum an...
