Description

Mobile phone protection film {protect film for mobile phone}

The present invention relates to a mobile phone protective film, and more particularly to a protective film for preventing damage to the LCD screen made of tempered glass in a mobile phone, especially a touch phone.

Currently, the surface of a wireless communication terminal, called a mobile phone, a mobile phone is largely divided into a liquid crystal screen portion and a keypad portion, in particular, the liquid crystal display portion is made of a special synthetic resin material to prevent damage.

However, LCD screens made of synthetic resins are resistant to impact, but weak to scratch, and often have an additional protective film for scratch prevention.

On the other hand, recently developed touch phones such as iPhones or smartphones are operated by using the static electricity generated when a person's finger touches, and thus the liquid crystal screen part is made of tempered glass that is well-through electricity. Tempered glass is surprisingly well broken when dropped.

Utility Model Registration No. 405882 (Mobile Phone Protective Film Structure)

Utility Model Application No. 20-2008-0011407 (LCD protective film for detecting button position of touch screen device)

Utility Model Registration No. 444279 (Liquid Information Film)

The present invention was invented to prevent the LCD screen of the touch phone made of tempered glass from being damaged, and by improving the existing protective film to prevent scratching and to prevent the tempered glass from being damaged by external impact. It is.

The film is adhered to the surface of the mobile phone body to protect the surface of the mobile phone body,

A hard coat layer 11 positioned on the top surface of the film;

A 100 μm PET film layer 12 located directly below the hard coating layer 11;

 An adhesive layer 13 positioned below the 100 μm PET film layer 12;

A 100 μm PET film layer 14 positioned below the pressure sensitive adhesive layer 13;

An adhesive layer 15 positioned below the 100 μm PET film layer 14;

A 100 μm PET film layer 16 positioned below the pressure sensitive adhesive layer 15;

An adhesive layer 17 positioned below the 100 μm PET film layer 16;

It is a mobile phone protective film 10, characterized in that consisting of; 23㎛ release film layer 18 located under the pressure-sensitive adhesive layer (17).

Recently developed touch phones such as iPhones and smartphones are operated by using static electricity generated when a person's finger touches them. There is a disadvantage that breaks surprisingly well when dropped.

However, when the protective film of the present invention is additionally attached to the tempered glass of the touch phone, the tempered glass of the touch phone can be prevented from being damaged by an external impact, thereby allowing users to use the product with confidence.

1 is a cross-sectional view of the film of the present invention.
Figure 2 is a cross-sectional view showing the adhesion state of the film of the present invention.

The film is adhered to the surface of the mobile phone body to protect the surface of the mobile phone body,

A hard coat layer 11 positioned on the top surface of the film;

A 100 μm PET film layer 12 located directly below the hard coating layer 11;

 An adhesive layer 13 positioned below the 100 μm PET film layer 12;

A 100 μm PET film layer 14 positioned below the pressure sensitive adhesive layer 13;

An adhesive layer 15 positioned below the 100 μm PET film layer 14;

A 100 μm PET film layer 16 positioned below the pressure sensitive adhesive layer 15;

An adhesive layer 17 positioned below the 100 μm PET film layer 16;

It is a mobile phone protective film 10, characterized in that consisting of; 23㎛ release film layer 18 located under the pressure-sensitive adhesive layer (17).

Referring to the present invention having such a configuration in more detail as follows.

First of all, the greatest feature of the present invention is that a single protective film is laminated in a plurality.

That is, as shown in Figure 1 by stacking a plurality of PET film layers with an adhesive, since the thickness is significantly thicker than the conventional protective film it is possible not only to prevent scratches but also to prevent damage to the tempered glass.

Originally, there was a scattering prevention PET film for preventing scratches or scattering when broken in a mobile phone. However, the existing scratch or emergency prevention PET film was so thin that even if it is added to the tempered glass 20 of the touch phone could not prevent the tempered glass 20 is broken.

However, the protective film of the present invention can prevent the liquid crystal display tempered glass 20 from being damaged by stacking a plurality of thin PET film layers.

That is, as shown in FIG. 2, when the protective film 10 of the present invention is additionally attached onto the tempered glass 20, even when the mobile phone is dropped on the floor, the thick protective film of the present invention softens the shock, so that the tempered glass is broken. Will be prevented.

On the other hand, in the above, since each PET film layer and the adhesive layer is transparent, there is no problem at all in displaying the screen even if several sheets are stacked.

On the other hand, as shown in FIG. 2, when attaching the film of the present invention to the tempered glass 20 of the cellular phone body, the release film layer 18 located at the bottom of the protective film 10 can be removed by simply attaching it. do.

On the other hand, while one embodiment of the present invention has been described as described above, the present invention is not limited to the above embodiment, the equivalent configuration in which the above embodiment is appropriately modified will include all of them.

The protective film for a mobile phone corresponding to the present invention will have sufficient industrial applicability since the effect is much superior to that of a conventional protective film for a mobile phone.
