Mobile phone protecting membrane

Abstract

The invention discloses a mobile phone protecting membrane, which consists of a transparent insulation basic material, a radio-frequency antenna which is made of a transparent conductive material, a radio-frequency communication chip, a protection layer, an underlay and a surface layer; the radio-frequency antenna is arranged on the lower surface of the insulation basic material, a bonding pad of the radio-frequency communication chip is connected with the input end of the radio-frequency antenna through conductive agent the protection layer is arranged on the outer side surface of the radio-frequency antenna to wrap the radio-frequency antenna and is closely combined with the insulation basic material; the underlay is arranged at the outer side of the protection layer and is bonded with the protection layer through an electrostatic parting way or a gum parting way; and the surface layer is arranged on the upper surface of the insulation basic material and is bonded with the insulation basic material in an electrostatic parting way. The product of the mobile phone protecting membrane can be used for the consumption electronic product fields such as different mobile phones, music player 4 (MP4) and the like, and the product is more attractive and more practical.

Description

technical field [0001] The invention relates to the field of mobile phone beauty and radio frequency identification, in particular to a protective film for mobile phones, which has the function of radio frequency identification and functions as a protective film, and can be used in electronic devices with liquid crystal display screens or touch screens to make the product more beautiful practical. Background technique [0002] Mobile phone protective film is a kind of cold lamination film used for mounting on the surface of mobile phone body, screen and other tangible objects. There are many kinds, which can be divided into: mobile phone screen protective film, mobile phone body protective film; Simple anti-scratch protective film to functional protective film, such as: anti-peeping film, mirror film, AR film, frosted film, anti-scratch protective film, anti-scratch protective film for mobile phone body, decorative protective film for mobile phone body, etc.; Its materials ...

AI Technical Summary

Problems solved by technology

[0004] However, no matter it is an indispensable part in RFID products of low frequency, high frequency or ultra high frequency: the radio frequency antenna is limited by the size and communication mode due to its physical characteristics, and the radio frequency antenna occupies an absolute position in the entire circuit. Most of the space size, and the materials currently used to make antennas are copper, aluminum, silver paste, carbon paste and other materials

Antennas made of these materials have a visible shape, which cannot be perfect on some radio frequency identification products that need to ensure the appearance

In order to cover up the influence of the antenna pattern of the RFID product on the product application, the design concept of matching the product with the antenna pattern is often adopted, but this method puts forward high requirements for the designer, and the result is often difficult to achieve the desired level

For products that need to be transparent, such as the protective film of mobile phones, if the antenna of the RFID tag product needs to be designed in the visible area of ​​the display screen, it will seriously affect the user's line of sight and affect the use

[0005] In order to solve the defects of the aesthetic application of the mobile phone protective film with radio frequency identification function, the present invention proposes a brand-new solution, so that the radio frequency antenna can be in a transparent state, and the visual effect of the user will not be affected during use
