 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view illustrating a liquid crystal protective film according to an embodiment of the present invention.

Referring to FIG. 1, the liquid crystal protective film 100 according to the present embodiment includes a protective film 110 and a lower film 120.

The lower film 120 includes a first lower film 121, a second lower film 122, and a third lower film 123.

Generally, a small number of buttons and a liquid crystal display 11 are formed on the mobile device 10, and the side surface of the liquid crystal 11 forms a frame. Since the liquid crystal 11 is formed of a transparent material and the scratches are permanently left even with a small impact or scratch, the protective film 110 is adhered to the frame by using the liquid crystal protective film 100 to protect It is important.

The protective film 110 exhibits a strong adhesive force only on the adhesive surface of the polymer material which is adhered to the liquid crystal 11 and has a function of easily attaching and detaching from the lower film 120 attached to the lower portion along the Z- do.

When the protective film 110 is adhered to the liquid crystal 11, the liquid crystal 11 is strongly adhered to the liquid crystal 11 so that fragments are not generated even when a strong impact is applied thereto, and the tensile force is excellent. And has a waterproof function to allow oil or water to flow without being absorbed. The protective film 110 has a smooth property so that the protective film 110 can smoothly move when the user touches and drags the protective film 110. In addition, a material having high light transmittance is used so that the image transmitted through the protective film 110 and displayed on the liquid crystal 11 can be viewed without loss of light as much as possible.

The protective film 110 may be formed of a glass material or a hybrid glass material in which the glass and the polymer are combined with each other. The glass may be formed by forming a protective film different from a protective film made of a polymer, Unlike polyethylene terephthalate (PET), it has a strong scratch durability.

The lower film 120 is coupled to the lower surface of the protective film 110 along the Z-axis to facilitate attachment and detachment to and from the adhesive surface of the protective film 110. The lower film 120 may include a first lower film 121 which forms an interface along the Y axis perpendicular to the Z axis and forms a relatively large area and a second lower film 121 which is narrower than the first lower film 121 The second lower film 122 and the third lower film 123 which form an area.

FIGS. 2 to 8 are perspective views illustrating steps of attaching the liquid crystal protective film of FIG. 1 to a liquid crystal of a mobile device.

Referring to FIGS. 2 and 3, the first lower film 121 attached to the protective film 110 before the liquid crystal protective film 100 is attached to the mobile device 10 is removed.

Referring to FIGS. 4 and 5, the protective film 110 is disposed so as to coincide with the rim of the liquid crystal 11. At this time, the adhesive force is not formed between the second lower film and the third lower film, and the protective film 110 having adhesive strength does not contact the liquid crystal at the rear side, so that the protective film 110 can be disposed at a desired position.

Referring to FIG. 6, when the protective film 110 is disposed so as to coincide with the rim of the liquid crystal 11, the central portion of the protective film 110 is pressed in the first direction. The protective film 110 is partially adhered to the liquid crystal 11 by the adhesion force of the back surface of the protective film 110.

Referring to FIG. 7, the second auxiliary film 122 is removed in a second direction while the protective film 110 is pressed to prevent the protective film 110 from being detached, and the third auxiliary film 123 is removed Remove in three directions.

Referring to FIG. 8, the first, second and third lower films 121, 122 and 123 are all detached from the protective film 110 and the protective film 110 is attached to the liquid crystal 11 do.

9 is a flowchart showing a method of attaching the liquid crystal protective film of Fig. 1 to a liquid crystal.

The first lower film 121 of the liquid crystal protective film 100 is removed (step S110).

The protective film 110 of the liquid crystal protective film 100 is placed on the liquid crystal 11 so that the protective film 110 and the liquid crystal 11 are aligned with each other.

The second lower film and the third lower film are removed while pressing the center of the protective film 110 (step S130).

The air or bubbles between the liquid crystal 11 and the protective film 110 are removed in a state where the protective film 110 is attached to the liquid crystal 11 at step S140.

According to the embodiments of the present invention as described above, the liquid crystal protective film 100 is formed on the lower film 120 such that the first lower film 121, the second lower film 122 and the third lower film 123 And can stably attach to the one end and the other end of the liquid crystal 11 so that it is possible to minimize the misalignment or misalignment when the protective film 110 is attached to the liquid crystal 11, .

In addition, the first lower film 121 stably attaches the protective film 110 in such a manner that the second and third lower films are detached in a stable state in which the adhesive force of the lower end of the protective film 110 is partially fixed by hand. It is possible to precisely adhere to the liquid crystal 11 so as not to deviate to the edge of the liquid crystal 11, thereby minimizing contamination, shortening the time for attaching, and there is no need to adjust it again so as not to deviate from the edge.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.

       The liquid crystal protective film capable of attaching the protective film in a stepwise manner to the liquid crystal according to the present invention has industrial applicability that can be used in an electronic apparatus including a mobile apparatus.

10: mobile device 11: liquid crystal
100: liquid crystal protective film 110: protective film
120: lower film 121: first lower film
122: second lower film 123: third lower film
