BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a protective film for an electronic device according to an embodiment of the present invention; FIG.

1 to 5, a protective film for an electronic device according to the present invention includes a planar portion P1 of an electronic device P and a curved edge formed along the edge of the planar portion P1 The protective film F includes a film body 10, a rim portion 20 formed along the rim of the film body 10, And a reinforcing part 30 for firmly adhering the frame 10 and the frame part 20 and preventing deformation of the film body 10.

The film body 10 is used as a general protective film and is made of a reinforced glass (hardened glass) material or a hard synthetic resin material such as PET, PC, or PMMA.

The film main body 10 may be made of a special synthetic resin material having a function of protecting the blue light or protecting the privacy according to the material.

The film body 10 is manufactured to have a size corresponding to the plane portion P1 of the electronic device and an adhesive layer 15 for attaching a protective film is formed on the rear surface and attached to the entire surface of the plane portion P1.

In the film body 10, various holes 11 are formed to expose a microphone, a camera and the like according to specifications of an electronic device to be attached. In the case of a product having a fingerprint recognition function like the iPhone 6, The corresponding cutting groove 12 can be further drilled.

The rim portion 20 is made of a soft synthetic resin material such as silicon, polyurethane, or sealant, and is adhered and fixed to the rim of the film body 10 through molding.

It is needless to say that the same adhesive is applied to the rear surface of the rim portion 20 when the adhesive is applied to the rear surface of the film body 10.

The rim portion 20 is a band-shaped member corresponding to the width of the left and right sides of the curved surface portion P2 formed along the rim of the front display portion of the smartphone, taking the curved surface value (curvature radius) into consideration.

Since the frame 20 made of soft synthetic resin is formed along the rim of the film body 10 when the protective film of the present invention is attached to the rim 20, So that it is possible to prevent the rim portion 20 from being lifted and separated from the curved portion P2 after the protective film is attached.

In the protective film of the present invention, the primer layer 14 is formed along the rim of the film body 10, and the film body 10 and the rim portion 20 are bonded together by the primer layer 14 .

The primer layer 14 may be formed by applying and coating a synthetic resin primer such as a silicon primer to the step portion 13 formed along the rim of the film body 10.

When the primer layer 14 is formed on the rim of the film body 10, the rim portion 20 is formed on the rim portion of the film body 10 while covering the primer layer 14 to improve the adhesion between the two members.

It is also possible that the frame portion 20 is made of soft colored synthetic resin to express the design of the front display portion of the smartphone in a personalized manner (like the iPhone 6, the curved portion P2 includes a special display and touch function If not). In this case, it is needless to say that the colored frame portion 20 can be implemented through printing instead of using a colored material.

3, in order to prevent deformation of the film body 10 and to enhance adhesion to the frame 20, the reinforcing portion 30 provided on the attachment surface of the film body 10 .

3, the reinforcing portion 30 of the present invention is composed of a reinforcing sheet 31 bonded to one surface of the film body 10 as a first embodiment.

The reinforcing sheet 31 may be an AB film sheet used for a reinforced glass protection film or the like, which is adhered and fixed to one surface of the film body 10. [

The reinforcing sheet 31 may be attached to either one of both surfaces of the film body 10 so as to prevent the reinforcing sheet 31 from being separated from the film body 10, It is more preferable that the reinforcing sheet 31 be adhered to the surface in the direction of attachment.

The sheet body 32 of the reinforcing sheet 31 is made of a hard synthetic resin material such as PET and is fixed to the film body 10 through the first adhesive layer 33 between the film body 10 and the seat body 32. [ And the reinforcing sheet 31 are adhered to each other and the second adhesive layer 34 is formed on one surface (rear surface) of the seat body 32 so that the protective film is adhered to the flat surface P1.

Preferably, the first adhesive layer 33 is an acrylic adhesive, and the second adhesive layer 34 is a silicone adhesive.

As the reinforcing sheet 31 is adhered and fixed to the rear surface of the film body 10, it is possible to prevent the film body 10 from being deformed in a manufacturing process of a protective film to be described later.

In the second embodiment, the reinforcing portion 30 is integrally formed with synthetic resin having the same softness as that of the rim portion 20. The rim portion 20 is bonded to one surface of the film body 10 together with the rim portion 20, And a reinforcing and adhering portion 30 which is made of a resin.

That is, the reinforcing and adhering part 35 is not made of a separate member and is further adhered to the rear surface of the film body 10, 35 are applied to the back surface of the film body 10 together.

As the rim portion 20 is adhered to the rear surface of the film body 10 together with the reinforcing and bonding portion 35, the deformation of the film body 10 and the separation of the rim portion 20 can be prevented.

A silicone adhesive is applied to the rear surface of the reinforcing portion 30 rather than the rear surface of the film body 10 when the reinforcing portion 30 composed of the reinforcing sheet 31 or the reinforcing and adhering portion 35 is applied in the present invention Of course, the protective film can be attached to the smartphone.

4 and Fig. 5 (other structures not shown in Figs. 4 and 5 are shown in Figs. 1 to 3). A method of manufacturing a protective film for an electronic device according to the present invention will be described.
