Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal protection module for electronic devices, a blank for the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal protection module for an electronic device such as a cellular phone, a blank for the same, and a mounting method.

A protection module for protecting a liquid crystal screen of an electronic device such as a mobile phone is known.

For example, Korean Patent No. 1576002 of the applicant discloses a colored adhesive surface protective film comprising a liquid crystal film coated with a pressure-sensitive adhesive on the bottom and a colored protective film adhered to the bottom of the liquid crystal film and divided into two.

Korean Patent No. 1510202 discloses a fixing film comprising a protective film coated with a pressure-sensitive adhesive and a removable film formed on the lower surface of the protective film and detachably coupled to the upper surface of the protective film. And the protective film is attached to the liquid crystal screen by removing the removable unit while the position fixing is performed on the liquid crystal screen.

However, in recent years, the release model of a mobile phone is substantially a 3D screen which is extended to the edge of the flat plate as far as the edge of the flat panel. In this case, the transparent sheet for protecting the screen of the mobile phone tends to be made soft and thin with a more flexible material so as to reliably cover the rounded portion including the edge of the edge or the border, which is insufficient for the conventional flat plate type.

In this case, during the process of attaching the transparent sheet, the transparent sheet is light and flexible, and it is shaken well. Recently, the surface of the liquid crystal screen of the mobile phone has been manufactured to have a very high slip degree for preventing contamination such as fingerprints. A positional deviation occurs. That is, in the case of the above-mentioned prior art, in the process of sequentially removing the divided removable units in a state where the position is fixed, the position of the liquid crystal is shifted due to the very smooth surface of the liquid crystal, When the position of the liquid crystal screen is 3D, such as the edge of the mobile phone, it is difficult to measure the outer area of the mobile phone LCD screen and the speaker or camera portion of the upper portion of the mobile phone LCD screen. In the case where there is no home button on the liquid crystal screen of the mobile phone, the reference point is located on the upper part of the speaker or the camera area, so that it is difficult to precisely measure the difficulty of attaching the transparent sheet to the mobile phone liquid crystal screen without gaps or air bubbles.

At the lower end of the front surface 40A, a guide bar 46 having a rectangular shape extending from the center to both sides extends outward with respect to the fold line 44 as a reference. The guide bar 46 is preferably the same size as the guide bar 36.

Fig. 2 is an exploded perspective view of an electronic apparatus liquid crystal protection module M as a final product in which the respective members of Fig. 1 are combined or integrated. In order to distinguish from the blank of Fig. 1, "" is added to the member numbers, and the description of members corresponding to the same configuration is omitted in order to avoid redundancy.

The liquid crystal protection module M includes a lower reinforcing sheet 4 ', an upper protective film 2', a lower protective film 3 'and a transparent liquid crystal protective sheet 1' in order from the bottom toward the electronic device such as the cellular phone H '). The upper protective film 2 'and the lower protective film 3' form the same layer.

The mobile phone H to which the liquid crystal protection module M of the present invention is applied is a model of a mobile phone with a 3D screen on which a liquid crystal screen extends to an edge E and has no home button on the front side. For example, the Galaxy S8 ™ and so on.

The fronts 10A ', 20A', 30A 'and 40A' of each sheet and film are facing the user and the backsides 10B ', 20B', 30B 'and 40B'

The transparent liquid crystal protective sheet 1 'is a thermoplastic transparent plastic sheet made of an acrylic polymer and can be made of PET (polyethylene terephthalate) and TPU (thermoplastic polyurethane). PET is suitable for hard, flat screen protection. TPU is suitable for curved edge (E) protection and is softer than PET. It has a lot of soft monomers in order to cover 3D screen extended to edge (E) Trend. In this case, it is very difficult to accurately attach the soft liquid crystal protective sheet 1 'to the position of the liquid crystal screen without fluctuation and deviation. However, the liquid crystal protection module M according to the embodiment of the present invention resolves such inconvenience.

The upper protective film 2 ', the lower protective film 3' and the lower reinforcing sheet 4 'may be any thermoplastic plastic sheet, but they are preferably made of PET. The upper and lower protective films 2 'and 3' may be formed by adding a pigment such as a pink, a purple or a red pigment or a colored film coated with these color layers in order to ensure visibility from the outside in the process of attaching the cellular phone H .

The flap 400 'of the lower reinforcing sheet 4' is provided with a region where the flap 200 'of the upper protective film 2' is to be positioned and a region where the lower protective film 3 ' Are provided in turn.

The speaker Hs of the cellular phone H is exposed to the outside by the closed slots 14 ', 24', and 44 'aligned in a row, and the camera lens or the operation button Hc is opened by the open slots 16 ', 26', 46 '; 18', 28 ', 48'.

The guide bar 36 'of the lower protective film 3' and the guide bar 46 'of the lower reinforcing sheet 4' are overlapped and aligned.

The sizes and shapes of the closed slots 14 ', 24', and 44 'and the guide bars 36' and 46 'are such that the transparent liquid crystal protective sheet 1' is aligned with the screen of the cellular phone H so that the transparent liquid crystal protective sheet 1 ' , And the model of the mobile phone (H).

The upper and lower protective films 2 'and 3' may have substantially the same size and shape as the transparent liquid crystal protective sheet 1 'except for the guide bar 36' and the flaps 200 'and 300' .

In the embodiment of the present invention, the guide bar 36 'is one of the important structures for aligning the transparent liquid crystal protective sheet 1' accurately and without gap on the 3D slipped liquid crystal screen. In conventional mobile phones, it is possible to attach and align a transparent sheet without a guide bar or simply with a slot, but it is not suitable as a structure for attaching to a liquid crystal screen which has a very high screen slip degree.

3 is a simplified view of an exploded cross-sectional view of the view of FIG.

The lower reinforcing sheet 4 'is in the form of a lower layer, the upper protective film 2' and the lower protective film 3 'are flush with each other toward the cell phone H, and the transparent liquid crystal protective sheet 1' ) Constitute the upper layer.

Adhesive material is applied to the back surfaces 20B 'and 30B' of the upper and lower protective films 2 'and 3' so that the lower reinforcing sheet 4 'is attached to the upper and lower protective films 2' and 3 ' . The adhesive backs 20B 'and 30B' provide adhesion during the process of attaching the liquid crystal protection module M so that the transparent liquid crystal protection sheet 1 'can be attached to the cellular phone H without shaking or variation .

A highly viscous adhesive material is applied to the back surface 10B 'of the transparent liquid crystal protective sheet 1' so that the upper and lower protective films 2 'and 3' are attached to the transparent liquid crystal protective sheet 1 '. The transparent liquid crystal protective sheet 1 'is directly attached to the liquid crystal screen of the cellular phone H owing to the adhesive material applied to the back surface 10B' so that the adhesive strength of the back surface 10B ' Is preferably larger than the adhesive force.

One of the features of the liquid crystal protection module M of the present invention is that the upper and lower protective films 2 'and 3' are arranged below the transparent liquid crystal protective sheet 1 '.

This arrangement can maintain a clean state by preventing foreign matter such as dust or the like from entering the back surface 10B 'of the transparent liquid crystal protective sheet 1' during the process of attaching to the cellular phone H as described later And provides the advantage of providing an adhesion process.

On the contrary, in the case of the prior art, it was easy to separate the supporting film by attaching the supporting film on the transparent sheet attached to the mobile phone, but it was difficult to prevent dust or fingerprints from adhering to the back side of the transparent sheet during the attaching process, As a result of attaching the sheet directly to the screen of the mobile phone (H), it is difficult to adjust the attachment position by moving the strongly attached sheet, and as the user touches the transparent sheet by hand to find the position, the sheet is wrinkled or the fingerprint is burnt, There were no disadvantages.

According to another embodiment of the present invention, the upper reinforcing sheet 100 'may be further laminated on the transparent liquid crystal protective sheet 1' as shown in FIG. An adhesive material is applied to the back surface of the upper reinforcing sheet 100 'so that the front surface 10A' of the transparent liquid crystal protective sheet 1 'is attached. Since the upper reinforcing sheet 100 'is for protecting the transparent liquid crystal protective sheet 1' from foreign substances such as dust and fingerprints, it is preferable that the upper reinforcing sheet 100 'is formed in the same shape as the transparent liquid crystal protective sheet 1' May be the same as the reinforcing sheet 4 '.

With the above-described structure, the liquid crystal protection module M according to an embodiment of the present invention is integrally completed with a composite layer structure of three layers or four layers and supplied as a product.

Hereinafter, a method of attaching the liquid crystal protection module M to the cellular phone H according to one embodiment of the present invention will be described with reference to FIG. 5 based on FIG. 2 to FIG.

The liquid crystal protection module M of the present invention is integrated into, for example, a three-layer structure as shown in Fig. 5 (a).

The transparent liquid crystal protective sheet 1 'is positioned on the side where the user looks, and the upper and lower protective films 2' and 3 'are attached in the same layer below the transparent liquid crystal protective sheet 1' The lower reinforcing sheet 4 'is attached.

The flap 200 'of the upper protective film 2' is positioned on the flap 400 'of the lower reinforcing sheet 4' and adjacent to the area where the mark 404 ' Quot; 3 "as the mark 304 'is visible from the outside, and the flap 300' of the lower protective film 3 'is positioned adjacent thereto.

First, the user sees the lower reinforcing sheet 4 ', which is recognized as a member to be separated first, by looking at the mark 404' of "1", by grasping the flap 400 ' 2 ', 3'). This state is shown in Fig. 5B.

Next, the liquid crystal protection module M of the present invention is used as a lower first guide for aligning the transparent liquid crystal protective sheet 1 'suitable for the 3D screen without deviation on the liquid crystal 3D screen of the cellular phone H, ', And closing slots 14' and 24 'as the upper second guide.

The user firstly aligns the fold line 34 'of the guide bar 36' with the bottom edge e of the cellular phone H and simultaneously aligns the closed slots 14 'and 24' with the speaker Hs And the guide bar 36 'is folded on the basis of the fold line 34' to cover the underside of the cellular phone H. The folded guide bar 36 'with respect to the lower edge e accurately covers the lower area 56' of the cellular phone. At this position, the transparent liquid crystal protective sheet 1 'is aligned on the liquid crystal 3D screen of the cellular phone H without any deviation. This state is shown in Fig. 5D. Since the upper and lower protective films 2 'and 3' are adhered to the liquid crystal screen by the adhesive force of the lower surfaces 20B 'and 30B', the stable adhesion state can be obtained without slippage despite the movement or shake of the cellular phone H .

Particularly, the guide bar 36 'is folded and covers the area 56' of the cellular phone so that the transparent liquid crystal protective sheet 1 ', the upper and lower protective films 2' and 3 ' Since they are naturally and precisely aligned, there is no need to re-adjust their positions, and therefore the attaching operation is very convenient. In this respect, the guide bar 36 'may be referred to as a reference member in the attaching operation.

On the other hand, since the upper and lower protective films 2 'and 3' are continuously attached to the transparent liquid crystal protective sheet 1 ', dust or the like is adhered to the back surface 10B' of the transparent liquid crystal protective sheet 1 ' It is possible to maintain the clean state at all times by preventing foreign matter or fingerprints from entering.

In this state, the user sees the upper protective film 2 'recognized as a member to be separated next by looking at the mark 204' of 2 ', and separates the upper protective film 2' by grasping the flap 200 ' . This state is shown in Fig. 5E. At this time, the lower protective film 3 'can be pressed to the mobile phone H with the other hand, so that only the upper protective film 2' can be stably pulled up.

The upper protective film 2 'is simultaneously separated from the liquid crystal screen of the cellular phone H and the transparent liquid crystal protective sheet 1'. The user can push the upper part of the transparent liquid crystal protective sheet 1 'by, for example, a suitable squeegee so as to adhere closely to the upper part of the liquid crystal screen without generating gaps or bubbles.

Next, in this state, the user grasps the bottom protective film 3 ', which is recognized as a member to be finally separated by looking at the mark 304 of "3", by grasping the flap 300' Remove it by removing it. This state is shown in Fig. 5f. At this time, the other part of the transparent liquid crystal protective sheet 1 ', which is attached with the other hand, can be pressed against the cellular phone H, so that only the lower protective film 3' can be stably pulled down.

It will be appreciated that the flaps 200 ', 300', 400 'function as a kind of handle and are integral and therefore very easy to separate.

The lower protective film 3 'is simultaneously separated from the liquid crystal screen of the cellular phone H and the transparent liquid crystal protective sheet 1'. At this time, the guide bar 36 'is also detached at the same time. The user can push the lower portion of the transparent liquid crystal protective sheet 1 'by, for example, a suitable squeegee so that the transparent liquid crystal protective sheet 1' is closely attached to the lower portion of the liquid crystal screen without generating gaps or bubbles.

In the above attaching operation, the lower protective sheet 3 'may be separated earlier than the upper protective sheet 2' regardless of the number of marks.

In the case of a four-layer structure as shown in FIG. 4, the upper reinforcing sheet 100 'may be finally separated from the transparent liquid crystal protective sheet 1' while using the above-described attachment method.

The transparent liquid crystal protective sheet 1 'is positioned on the upper and lower protective sheets 2' and 3 'until the upper and lower protective films 2' and 3 'are separated and the upper and lower protective films 2' The upper and lower protective films 2 'and 3' are touched by hand and relatively freely moved while setting the attachment position of the transparent liquid crystal protective sheet 1 ' There are advantages to be able to.

These advantages are particularly useful for precise attachment of flexible sheets of transparent material that adhere to the 3D underside of modern mobile phones.

It is preferable that the upper and lower protective films 2 'and 3' have substantially the same size and shape as the transparent liquid crystal protective sheet 1 'except for the guide bar and the flip in the state where they are adjacent to each other. Is a reference for setting the final attachment position of the first lens 1 '.

The attachment work is completed by separating the upper and lower protective films 2 'and 3' and attaching the transparent liquid crystal protective sheet 1 'to the front surface of the cellular phone H as it is, It is possible to avoid the inconvenience of re-adjusting the attachment position of the mobile phone 1 'to the screen of the mobile phone.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

For example, the lower reinforcing sheet 4 'is for protecting the lower surface of the liquid crystal protection module M and is first separated so that the guide bar 46' or the open and closed slots 44 ', 46', 48 ' It may not be formed.

Also, as long as the upper guide and the lower guide can be provided, the object of the closed slot is not limited to the speaker, and it is also possible to use an open slot as an upper guide.

Although the guide bars 36 'and 46' are shown to be aligned with the lower edges, the guide bars 36 'and 46' may be formed at the upper edge of the cell phone as a segment mark.

In addition, the upper protective film 2 'and the lower protective film 3' may be formed as an integral type, not as a separate type, or as three or more divided types.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
