Conductive lining for liquid crystal panel of radio mobile communication terminal, and its mfg. method

Abstract

The invention provides a conductive liquid crystal screen spacer for a wireless mobile communication terminal and a manufacturing method thereof. The pad not only has cushioning properties, elastically supporting the liquid crystal screen on the shell, but also has conductivity, which can absorb and shield static electricity and electromagnetic waves. Use a conductive adhesive to overlap 1 to 4 layers of functional fabrics made of stretchable fibers such as woven, non-woven, and braided fabrics impregnated with conductive metals such as nickel, and cut them into desired shapes with an automatic cutting machine. After the shape of the above-mentioned cutting surface is heat-melted, so that it has formability, cushioning, and electrical conductivity at the same time, each section is fixed after heat-melting, and the lint and dust are removed. When the functional fabric is actually applied to the liquid crystal screen gasket of the wireless mobile communication terminal, it not only has a good cushioning effect, but also has a good effect of absorbing and shielding electromagnetic waves and static electricity generated inside and outside the terminal.

Description

technical field [0001] The present invention relates to a liquid crystal screen spacer for a wireless mobile communication terminal and a manufacturing method thereof, more specifically, relates to cushioning to elastically support a liquid crystal screen, and conductivity to absorb and shield static electricity and electromagnetic waves Liquid crystal panel spacer and manufacturing method thereof. Background technique [0002] As we all know, a digital wireless mobile communication terminal must be equipped with a liquid crystal screen (LCD) to display characters or symbols on the outside. The LCD screen gasket made of rubber and polyurethane is filled between the LCD screen and the outer frame to elastically support the LCD screen. LCD screen. [0003] On the other hand, with the awareness of the danger of harmful electromagnetic waves, there is also a tendency for wireless mobile communication terminals to set a benchmark value relative to...

AI Technical Summary

Problems solved by technology

[0004] However, although the liquid crystal screen gasket made of general rubber and polyurethane has cushioning properties, it has almost no ability to absorb or shield electromagnetic waves, so it is generated by the internal circuit and emitted outwards through the gap between the liquid crystal screen and the external frame. It can be said that the electromagnetic waves or static electricity are completely exposed without shielding. Even if the above problems are tried to solve the above problems by coating or attaching conductive materials to other parts of the above terminals, there is no method that can fundamentally absorb or Shield the electromagnetic waves or static electricity generated by the LCD screen

[0005] In order to solve these problems, conductive materials can be used to make liquid crystal screen gaskets that can absorb and shield electromagnetic waves or static electricity, but almost all of these conductive materials have problems of weak cushioning ability and poor formability, so they cannot be used directly.
