First of all, it should be noted that among the drawings, the same components or parts are indicated by the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the gist of the present invention.

도 1은 일실시예에 따른 MLA 층을 도시하는 도면이고, 도 3은 일실시예에 따른 MLA 층이 형성된 휴대폰 데코레이션 필름을 도시하는 도면이다.1 is a view showing an MLA layer according to an embodiment, and FIG. 3 is a view showing a mobile phone decoration film having an MLA layer according to an embodiment.

휴대폰 데코레이션 필름(100)은 휴대폰의 뒷쪽에 형성되는 백커버에 적용되는 필름으로서, PC(Polycarbonate)층(110), PC층(110)의 전면에 원단 압출 과정을 통해 렌즈코팅형태로 형성된 MLA(Micro Lens Arrary)층(120), UV 패턴층(130), 증착층(140), 실크층(150) 순으로 구성된다.Mobile phone decoration film 100 is a film applied to the back cover formed on the back of the mobile phone, PC (Polycarbonate) layer 110, MLA formed in the form of a lens coating through a fabric extrusion process on the front of the PC layer 110 ( It is composed of a Micro Lens Arrary) layer 120, a UV pattern layer 130, a deposition layer 140, and a silk layer 150 in this order.

이와 같은 일실시예에 따른 원단 압출식 마이크로 렌즈 어레이가 적용되는 휴대폰 데코레이션 필름을 제조하는 방법은 먼저, PC층(110)을 형성하는 단계를 가진다.The method of manufacturing a mobile phone decoration film to which the fabric extruded micro-lens array is applied according to one embodiment has the step of forming the PC layer 110 first.

다음으로, PC층(110)의 전면에 MLA(Micro Lens Arrary)층을 형성하고, MLA층을 형성하면서 PC를 원단 압출하는 단계를 가진다.Next, a Micro Lens Arrary (MLA) layer is formed on the entire surface of the PC layer 110, and the PC is extruded from the fabric while forming the MLA layer.

압출 성형이란 고정　단면　윤곽의 물체를 만들기 위해 사용하는 공정으로서, 압출성형공정은 휴대폰 데코레이션 필름의 강도를 높일 수도 있다.Extrusion molding is a process used to make objects with a fixed cross-section and contour, and the extrusion molding process can increase the strength of mobile phone decoration films.

휴대폰 데코레이션 필름을 제조하는 방법은 원료로부터 PC층을 압출 형성되는 과정에서 적어도 하나 이상의 롤러를 이용할 수 있다.A method of manufacturing a cell phone decoration film may use at least one roller in the process of extruding the PC layer from raw materials.

일례로, 휴대폰 데코레이션 필름을 제조하는 방법은 PC의 원료가 압출기의 기기에 주입되면, 원료를 뜨겁게 녹여 젤상태로 만들 수 있고, 젤상태의 원료를 평판 형태로 압착하여 펴주거나, 롤러를 통해 두께가 일정하고 표면을 평탄하게 만들어 PC로 압출성형할 수 있다.For example, in the method of manufacturing a mobile phone decoration film, when PC raw materials are injected into an extruder device, the raw materials can be melted hot and made into a gel state, and the raw materials in the gel state are compressed and spread in a flat form, or through a roller to form a thickness. It can be extruded with PC by making the surface constant and flat.

이 과정에서 일정한 압력의 공기를 쏘아 패널의 평활도를 유지할 수 있으며, 휴대폰 데코레이션 필름을 제조하는 방법에 따르면 압착을 위한 평판이나 롤러에 MLA층이 형성될 수 있도록 MLA층 모양이 음각으로 형성될 수 있다.During this process, air of constant pressure can be blown to maintain the flatness of the panel, and according to the method for manufacturing mobile phone decoration film, the shape of the MLA layer can be formed in a negative shape so that the MLA layer can be formed on a flat plate or roller for compression. .

이에 압출과정에서 PC에 MLA가 패터닝될 수 있다.Accordingly, MLA may be patterned on the PC during the extrusion process.

즉, 일실시예에 따른 MLA층(120)은 PC층(110)의 압출성형 과정에서 생성되는 가공된 표면으로서, MLA층(120)과 PC층(110)은 동일한 원료일 수 있다.That is, the MLA layer 120 according to one embodiment is a processed surface generated during the extrusion molding of the PC layer 110, and the MLA layer 120 and the PC layer 110 may be the same raw material.

한편, 도 4에 나타낸 것과 같이, PC층(110)과 PC층(110)의 전면에 원단 압출 과정에서 렌즈코팅형태로 형성된 MLA층(120)을 형성하는 것이 특징으로서, MLA층(120)은 기본 레이어 및 돌기 형태의 렌즈가 일정 간격을 가지고 형성된다.On the other hand, as shown in Figure 4, it is characterized by forming the PC layer 110 and the MLA layer 120 formed in the form of a lens coating in the fabric extrusion process on the entire surface of the PC layer 110, the MLA layer 120 The base layer and the projection-type lens are formed at regular intervals.

이때, 상기 MLA층의 렌즈는 그 너비(a)를 100㎛ ∼ 130㎛, 두께(c)는 5㎛ ∼ 15㎛, 렌즈 사이 간격(b)은 5㎛ ∼ 15㎛으로 형성하여 상기한 수치 범위 내에서 수치를 조절함으로써 헤이즈감을 조절할 수 있게 해 준다.At this time, the lens of the MLA layer is formed to have a width (a) of 100 μm to 130 μm, a thickness (c) of 5 μm to 15 μm, and a distance (b) between lenses of 5 μm to 15 μm, so that the above numerical range By adjusting the value within, it is possible to adjust the haze.

다음으로 PC층(110)의 배면에는 소정의 패턴으로 디자인되는 UV 패턴층(130)이 형성되는 단계를 가진다.Next, a UV pattern layer 130 designed in a predetermined pattern is formed on the rear surface of the PC layer 110.

다음으로 UV 패턴층(130) 배면에 UV 패턴층(130)의 패턴에 상응하도록 증착층(140)이 형성되는 단계를 가진다. 증착층(140)은 소정의 투과율을 갖는 재질로 이루어지고, UV 패턴층(130)에 형성된 패턴을 유지하도록 하며, 투과율 또는 반사율을 조절할 수 있다. 또한, 증착층(140)은 전기전도성을 가진 투명 도전층으로서 인듐, 크롬, 주석 또는 ITO(Indium Tin Oxide) 중 어느 하나 이상을 포함하여 형성될 수 있다.Next, a deposition layer 140 is formed on the rear surface of the UV pattern layer 130 to correspond to the pattern of the UV pattern layer 130 . The deposition layer 140 is made of a material having a predetermined transmittance, maintains a pattern formed on the UV pattern layer 130, and can adjust transmittance or reflectance. In addition, the deposition layer 140 is a transparent conductive layer having electrical conductivity and may be formed by including any one or more of indium, chromium, tin, or indium tin oxide (ITO).

다음으로 증착층(140)의 배면에 실크 인쇄층(150)이 형성되는 단계를 가진다. 실크 인쇄층(150)은 실크 스크린 인쇄방식으로 형성되고, 로고, 제품 모델명, 버튼 또는 특정 무늬가 인쇄될 수도 있다.Next, the silk printing layer 150 is formed on the back surface of the deposition layer 140 . The silk printing layer 150 is formed by silk screen printing, and a logo, product model name, button, or specific pattern may be printed.

다음으로 실크 인쇄 후 3D금형 타발을 진행하는 포밍작업단계을 거쳐 입체적인 미감을 제공한다.Next, it provides a three-dimensional sense of aesthetics through the forming work step in which 3D mold is punched out after silk printing.

다음으로 포밍작업을 거친 휴대폰 데코레이션 필름(100)을 한 셀(cell)씩 커팅하는 CNC 가공단계을 실행하게 된다.Next, a CNC processing step of cutting the mobile phone decoration film 100 that has undergone the forming operation cell by cell is executed.

도 2는 MLA층(120)이 형성된 휴대폰 데코레이션 필름이 부분 적용된 휴대폰 케이스(200)를 도시하는 도면으로서, 휴대폰 케이스(200)는 휴대폰 데코레이션 필름(100)이 적용된 부분(220)과 적용되지 않은 부분(210)이 명확하게 구분될 수 있으며, 육안으로 적용된 부분(220)의 헤이즈감을 확인 할 수 있다.Figure 2 is a view showing a mobile phone case 200 to which the MLA layer 120 is formed and a mobile phone decoration film is partially applied. (210) can be clearly distinguished, and the haze of the applied portion (220) can be confirmed with the naked eye.

즉, 본 발명을 이용하면, MLA층을 통해 기존 백커버에 적용되는 데코레이션 필름에 비해 육안상 헤이즈감 있게 형성되어 사용자에게 다양한 심미감을 제공하고, 기존 필름 대비 내스크레치성, 내약품성 및 내구성이 향상되며, 지문 등의 자국이 남지 않아 높은 식별성 상태를 확보할 수 있다.That is, when the present invention is used, compared to the decoration film applied to the existing back cover through the MLA layer, it is formed to have a hazy feeling to the naked eye, providing various aesthetic feelings to the user, and improving scratch resistance, chemical resistance and durability compared to the existing film. It does not leave traces such as fingerprints, so it is possible to secure a high identification state.
