Film member for electronic device

Abstract

Disclosed is a film member for an electronic device capable of preventing malfunction of an electrostatic touch screen and expressing a design characteristic of unique texture. The film member used for the electrostatic touch screen of the electronic device having the electrostatic touch screen, includes: a transparent film; and a window decoration made of a metallic material and provided on one surface of the transparent film, wherein the window decoration includes a plurality of metallic thin film figures which are electrically insulated from each other.

Description

TECHNICAL FIELD[0001]The present invention relates to a film member for an electronic device, and more particularly, to a film member for an electronic device having a window decoration made of a metallic material capable of preventing malfunction of a touch screen.BACKGROUND ART[0002]Generally, in devices installed with a touch screen in electronic devices, for example, a smart phone, a tablet, a laptop, a monitor, and the like having a touch screen, a transparent cover is attached to the front surface of the touch screen.[0003]Further, a window decoration may be formed at the edge of the transparent cover. The window decoration may be provided as a use of covering non-transparent components disposed therebelow, for example, a wire member (not illustrated) and a circuit board (not illustrated) which are disposed at the edge of a touch panel sensor, and formed by a general printing process and the like.[0004]Meanwhile, recently, the performance of the electronic device is important,...

AI Technical Summary

Benefits of technology

This patent describes a way to prevent malfunctions with a touch screen that is designed to look like metal. The invention uses a window decoration made of multiple thin metallic figures that are electrically insulated from each other to prevent interference and signal mis-transmission caused by the metal. The transparent film has curved parts to scatter light and minimize reflective light caused by the window decoration. The invention also includes a high-resistive printing layer to prevent static electricity accumulation and malfunctions in the touch screen. The technical effects of the invention are to improve the design and functionality of the touch screen, enhancing user experience.

Problems solved by technology

However, when the window decoration is formed of a metallic material, there is a problem in that malfunction of the touch screen is caused by a unique electric characteristic of the metal.

Particularly, in the case where the window decoration made of a metallic material is used, when a touch operation is performed at the edge of an electrostatic touch screen adjacent to the window decoration, there are problems in that it is difficult to accurately sense the touch operation of the electrostatic touch screen by an electric effect of the window decoration and undesired malfunction is caused.

Further, since a plurality of wire members transferring a touch signal of the electrostatic touch screen is disposed below the metallic window decoration, even in the case where the touch operation is performed at the center other than the edge of the electrostatic touch screen, there are problems in that interference occurs by the electric characteristic of the window decoration or malfunction occurs by transferring the signal to another undesired wire member, when the signal by the touch operation is transferred according to a specific wire member.

Accordingly, recently, various studies for the window decoration capable of preventing malfunction of the touch screen and expressing the unique design characteristic have been conducted, but are not yet sufficient and thus the development thereof has been required.
