Abstract

A method of attaching a protective film on a display of a terminal includes: arranging an auxiliary member in a position setting space of a position setting plate and the protective film on a lower surface of the auxiliary member; arranging the terminal within the position setting space such that the display of the terminal faces the protective film; and applying an external force through a hole of the position setting plate to attach the protective film on the display of the terminal, the hole exposing a portion of the auxiliary member therethrough, wherein the auxiliary member has a first rectangular through-hole and a second rectangular through-hole exposing the protective film therethrough.

First claim

What is claimed is:

1 . A method of attaching a protective film on a display of a terminal, the method comprising:
arranging an auxiliary member in a position setting space of a position setting plate and the protective film on a lower surface of the auxiliary member; arranging the terminal within the position setting space such that the display of the terminal faces the protective film; and applying an external force through a hole of the position setting plate to attach the protective film on the display of the terminal, the hole exposing a portion of the auxiliary member therethrough, wherein the auxiliary member has a first rectangular through-hole and a second rectangular through-hole exposing the protective film therethrough, wherein the hole of the position setting plate is defined at the position setting space, such that the first rectangular through-hole and the second rectangular through-hole of the auxiliary member communicate with the hole of the position setting plate when the auxiliary member is arranged in the position setting space, and wherein the applying of the external force through the hole includes applying the external force directly on the protective film through the first rectangular through-hole and the second rectangular through-hole to have a higher downward adhesion pressure between the protective film and the display of the terminal at where the first rectangular through-hole and the second rectangular through-hole are present than another downward adhesion pressure at where the first rectangular through-hole and the second rectangular through-hole are not present, thereby guiding adhesion direction of the protective film, wherein the position setting plate includes at least one guide protrusion disposed on the position setting plate, the at least one guide protrusion surrounding the position setting space to guide aligning of the terminal in the position setting space, wherein a removable member is attached to a top of the position setting plate, wherein a part of the removable member is configured to be removably attached to the protective film through the hole of the position setting plate and the first and second rectangular through-holes of the auxiliary member, wherein the auxiliary member further includes a first one-side-open rectangular through-hole at one front end portion of the auxiliary member and a second one-side-open rectangular through-hole at one rear end portion of the auxiliary member, wherein the first rectangular through-hole and the second rectangular through-hole are positioned between the first one-side-open rectangular through-hole and the second one-side-open rectangular through-hole.

2 . The method of claim 1 ,
wherein the first one-side-open rectangular through-hole exposes the protective film therethrough, and the second one-side-open rectangular through-hole exposes the protective film therethrough, and wherein the applying of the external force through the hole further includes applying the external force directly on the protective film through the first one-side-open rectangular through-hole and the second one-side-open rectangular through-hole to have a higher downward adhesion pressure between the protective film and the display of the terminal at where the first one-side-open rectangular through-hole and the second one-side-open rectangular through-hole are present than another downward adhesion pressure at where the first one-side-open rectangular through-hole and the second one-side-open rectangular through-hole are not present, thereby guiding the adhesion direction of the protective film.

3 . The method of claim 2 ,
wherein the first one-side-open rectangular through-hole has a width smaller than a width of the first rectangular through-hole, wherein the second one-side-open rectangular through-hole has a width smaller than a width of the first rectangular through-hole, wherein the adhesion direction of the protective film is further guided in a direction from the first rectangular through-hole and the second rectangular through-hole to the first one-side-open rectangular through-hole and the second one-side-open rectangular through-hole, respectively, due to the smaller widths of the first and second one-side-open rectangular through-holes causing a lower adhesion pressure.

4 . The method of claim 1 ,
wherein the protective film has an attachment surface on a lower surface of the protective film, and wherein the display of the terminal is arranged apart from the attachment surface of the protective film by a predetermined distance, when the terminal is arranged in the position setting space.

5 . The method of claim 1 ,
wherein the first rectangular through-hole and the second rectangular through-hole are spaced apart from each other along a forward-backward direction at a center portion of the auxiliary member, such that the adhesion direction of the protective film is guided in the forward-backward direction.

6 . The method of claim 5 ,
wherein, when the external force moves in the forward-backward direction while pressing against the protective film or the auxiliary member through the hole, the adhesion direction of the protective film is guided in a dispersing manner from a center thereof up to an edge thereof.

7 . A film attachment device comprising:
a position setting plate including: a main body having a hole and a position setting space to accommodate a terminal thereon; and at least one guide protrusion disposed on the main body, the at least one guide protrusion surrounding the position setting space to guide aligning of the terminal in the position setting space; an auxiliary member having first and second rectangular through-holes positioned apart from each other to be exposed to an outside through the hole of the position setting plate, the auxiliary member being disposed on a lower surface of the main body; a protective film disposed to cover bottoms of the first and second rectangular through-holes; and a removable member attached to a top of the position setting plate, wherein a part of the removable member is configured to be removably attached to the protective film through the hole of the main body and the first and second rectangular through-holes of the auxiliary member, wherein the auxiliary member further includes a first one-side-open rectangular through-hole at one front end portion of the auxiliary member and a second one-side-open rectangular through-hole at one rear end portion of the auxiliary member, wherein the first and second rectangular through-holes are positioned between the first one-side-open rectangular through-hole and the second one-side-open rectangular through-hole.

8 . The film attachment device of claim 7 ,
wherein the first one-side-open rectangular through-hole is configured to expose one portion of an upper surface of the protective film, and wherein the second one-side-open rectangular through-hole is configured to expose another portion of the upper surface of the protective film.

9 . The film attachment device of claim 8 ,
wherein one front portion and one rear portion of the protective film are exposed to a space over the auxiliary member through the first and second one-side-open rectangular through-holes, respectively.

10 . The film attachment device of claim 7 ,
wherein the position setting plate further comprises: a guide unit coupled, at a position spaced apart from the position setting space, to the lower surface of the main body.

11 . The film attachment device of claim 7 ,
wherein the auxiliary member further includes at least one through-hole defined on the auxiliary member, the at least one through-
