Problems solved by technology

Although this problem can be avoided by using a low-viscosity sealant obtained by dissolving the sealant in a solvent, the gas generated by the evaporation of the solvent may pollute the environment, causing pollution problems

Embodiment Construction

[0014] A method of applying a sealant according to the present invention will be described in detail by way of example with reference to the accompanying drawings. The invention is described in terms of a plasma display comprising glass substrates which are brought together and sealed at the end faces using known methods such as figure 2 shown and described above. Figure 1A with 1B A method of applying a sealant in the process of manufacturing a plasma display according to the present invention is briefly shown. figure 2 with 3 The same elements in are denoted by the same reference numerals. Figure 1A is a simplified view of the sealant applied in the form of a flange, Figure 1B is a simplified view of compressed gas being sprayed from a gas nozzle onto a sealant.

[0015] Referring to the drawings, a plasma display 1 includes a front glass plate 2, a rear glass plate 3, and various kinds of functional films 4 disposed between the glass plates, including electrode film...

Abstract

In the process for producing a laminated substrate (1) such as electronic substrates (2; 3), when applying a sealing agent (7) to the end face of substrates (2, 3) combined together to seal it, first the sealing agent (7) is applied to a target area in the form of successive beads (7), and then a stream of compressed gas (10) is blown against the successive beads (7) from a gas ejecting nozzle (9) so as to scan the successive beads (7). The method can effectively fill the indentation or the stepped area formed along the end face with the sealing agent (7).

Description

technical field [0001] The present invention relates to a method of applying an encapsulant (sealing material) for insulation and moisture protection during the manufacture of electronic substrates. More specifically, the present invention relates to a method of applying an encapsulant capable of sealing the end faces of glass substrates of a plasma display to be brought together. Background technique [0002] First, a known method of the above type is described by a method of manufacturing a plasma display. Plasma displays use gas discharge between a pair of electrodes to generate ultraviolet light, and use the generated ultraviolet light to excite fluorescent elements to generate visible light. Plasma displays usually have a sandwich-type layered structure, and different kinds of functional films are formed between the front glass plate and the rear glass plate, including electrode films, fluorescent films, and ribs that carry the fluorescent films. After the wires are w...
