Description

충전단자를 이용하여 부착이 가능한 휴대단말기용 디스플레이 보호필름 및 그의 제조장치 및 제조방법Display protective film for portable terminal that can be attached using charging terminal and its manufacturing apparatus and manufacturing method
본 발명은 휴대단말기용 디스플레이 보호필름에 관한 것으로 특히, 보호필름 하단에 돌출 부위를 생성하고 홈을 형성하고, 충전단자를 홈에 끼워 보호필름을 중앙에서 흐트러짐 없이 휴대단말기 디스플레이에 빠르고 정확하게 부착할 수 있도록 하는, 충전단자를 이용하여 부착이 가능한 휴대단말기용 디스플레이 보호필름 및 그의 제조장치 및 제조방법에 관한 것이다. The present invention relates to a display protective film for a portable terminal, and in particular, a protruding portion is formed at the bottom of the protective film and a groove is formed, and the protective film can be quickly and accurately attached to the display of a portable terminal without being disturbed in the center by inserting the charging terminal into the groove. It relates to a display protective film for a portable terminal that can be attached using a charging terminal and an apparatus and a method for manufacturing the same.
일반적으로, 많은 사람들이 최근 널리 보급되고 있는 스마트폰이나 스마트 패드와 같은 개인 휴대형 단말기는 사용자의 편의성을 고려하여 비교적 넓은 터치스크린 기능의 화면표시장치를 갖는다.In general, a personal portable terminal such as a smart phone or a smart pad, which has been widely used by many people in recent years, has a screen display device having a relatively wide touch screen function in consideration of user convenience.
터치스크린 기능의 화면표시장치는 별도의 문자입력용 기계적 키패드 없이도 화면터치를 통하여 사용자가 원하는 문자나 기호 등을 입력하고 각종 기능메뉴를 직관적으로 선택할 수 있게 함으로써 사용자에게 편리성을 제공하지만, 빈번한 터치나 기타 입력 펜의 사용으로 인하여 표시장치의 액정화면이 쉽게 손상될 위험이 있다.The screen display device with the touch screen function provides convenience to the user by allowing the user to input desired characters or symbols and intuitively select various function menus through the screen touch without a separate mechanical keypad for character input, but frequent touches. There is a risk that the LCD screen of the display device is easily damaged due to the use of other input pens.
최근에는 이를 감안하여 터치스크린 타입의 디스플레이장치를 갖는 개인휴대단말기 제조사에서는 터치스크린 액정화면의 내구성 보강을 위해 고가의 강화유리로 된 보호패널을 액정화면에 부착시키고 있으나, 이는 휴대단말기의 부피와 중량의 증가문제와 제품 원가상승을 초래하게 되며, 강화유리 보호패널에 문제가 발생하게 될 경우 보수비용이 증가하게 되는 단점을 가지게 된다.In recent years, in consideration of this, manufacturers of personal portable terminals having a touch screen type display device attach a protective panel made of expensive tempered glass to the LCD screen to reinforce the durability of the touch screen LCD screen, but this is the volume and weight of the portable terminal. This leads to an increase in product cost and an increase in product cost, and if a problem occurs in the tempered glass protection panel, the maintenance cost increases.
이에 따라 많은 개인 휴대단말기 사용자들은 자신이 소지한 휴대단말기의 액정화면을 항상 선명하고 깨끗한 상태로 보호 유지할 수 있는 저 비용의 방책으로 투명의 보호필름을 선택하고 있다.Accordingly, many personal portable terminal users choose a transparent protective film as a low-cost measure to protect and maintain the LCD screen of their portable terminal in a clear and clean state at all times.
대부분의 휴대단말기용 디스플레이 보호필름은 디스플레이 액정화면과 대면 하게될 한쪽 면에 점착층이 마련되고, 이 점착층이 마련된 한 면과 그 반대 면의 보호를 위해 상기 보호필름의 양쪽면에 각각 제1,2 보호지를 부착하게 되므로 최종제품은 3층 필름의 구조로 만들어지게 되며, 이러한 보호필름은 다양한 휴대단말기의 디스플레이의 화면 사이즈별로 미리 재단 제작되어 소비자에게 공급된다.In most display protective films for portable terminals, an adhesive layer is provided on one side to face the display liquid crystal screen, and first on both sides of the protective film to protect one side on which the adhesive layer is provided and the other side. ,2 Since the protective paper is attached, the final product is made in a structure of a three-layer film, and this protective film is pre-cut for each screen size of the display of various portable terminals and supplied to consumers.
따라서 휴대단말기 사용자는 자신의 휴대단말기의 디스플레이 화면 사이즈에 맞는 보호필름을 선택 구매하여 휴대단말기의 액정화면에 부착 사용하게 되는데, 그 부착방법을 보면, 먼저 휴대단말기의 액정화면 사이즈에 알맞는 액정보호필름의 접착면 제1의 보호지를 제거하여 휴대단말기의 액정화면에 정확히 일치시켜 부착한 다음, 해당 액정보호필름의 표면에 부착된 제2의 보호지를 제거하는 것으로 휴대단말기 등의 액정화면에 보호필름 부착코팅을 완성하게 된다.Therefore, a mobile terminal user selects and purchases a protective film suitable for the display screen size of his or her mobile terminal and attaches it to the LCD screen of the mobile terminal. Looking at the method of attachment, first, the LCD protection suitable for the LCD screen size of the mobile terminal After removing the first protective paper on the adhesive side of the film, attaching it to the LCD screen of the mobile terminal, and then removing the second protective paper attached to the surface of the corresponding LCD protective film. Attachment coating is completed.
그런데, 휴대단말기 등의 액정화면에 보호필름을 기포가 없는 상태로 정확히 부착하는 일은 단 한번의 오차도 허용하지 않는 매우 세밀하고 조심스러운 작업이어서 휴대단말기 표면에의 보호필름 부착 작업은 숙련자가 아니면 올바른 부착 성공 확률이 매우 낮기 때문에, 일반인의 경우 몇 번의 시행 오차를 거쳐야만 비로소 휴대단말기 등의 액정화면 사이즈에 일치시켜 내부 기포 없이 보호필름을 부착시킬 수가 있다.However, attaching the protective film to LCD screens such as mobile terminals without bubbles is a very detailed and careful operation that does not allow even a single error. Therefore, attaching the protective film to the surface of the mobile terminal is correct unless you are an expert. Since the probability of success of attachment is very low, the general public can attach a protective film without internal bubbles by matching the size of a liquid crystal screen of a portable terminal only after several trial errors.
이를 개선할 수 있는 방안으로 보호필름의 점착면 보호지의 중앙부위를 가로지르는 절단면을 형성해 주는 방법이 국내공개특허 2018-0021490호에 개시되어 있다.As a way to improve this, a method of forming a cut surface crossing the central part of the adhesive surface of the protective film is disclosed in Korean Patent Publication No. 2018-0021490.
종래의 휴대단말기 액정필름은 보호와 점착을 위해 저면에 점착제가 도포된 액정필름; 액정필름 하부에 점착면 보호필름과 보호필름이 부착되고,A conventional liquid crystal film for a portable terminal includes a liquid crystal film coated with an adhesive on a bottom surface for protection and adhesion; An adhesive surface protective film and a protective film are attached to the bottom of the liquid crystal film,
액정필름의 상부에 보호필름이 부착되며, 상기 점착면 보호필름의 일 측에 각각 점착면 보호필름 탭; 보호필름 탭; 절취선으로 구성된다.A protective film is attached to the upper portion of the liquid crystal film, and each adhesive surface protective film tab on one side of the adhesive surface protective film; Protective film tab; It consists of perforations.
이러한 종래 기술에서는 액정필름이 휴대단말기 디스플레이와 접하는 면에 점착제가 도포되는데, 상기 점착면 보호필름과 보호필름은 액정필름의 하부 점착면을 보호하는 필름이고, 보호필름은 상부에 부착되어 사용자와 맞닿는 액정필름을 보호하는 역할을 한다.In such a conventional technology, an adhesive is applied to the surface of the liquid crystal film in contact with the display of the mobile terminal, and the adhesive surface protective film and the protective film are films that protect the lower adhesive surface of the liquid crystal film, and the protective film is attached to the upper part to contact the user. It serves to protect the liquid crystal film.
상기와 같이 구성된 종래의 액정보호필름을 부착하는 방법은 작업자 판단에 의해 부착위치를 가늠한 후점착면 보호필름 탭을 벗겨내어 액정필름 상단면을 휴대단말기 액정에 상단에 임시로 부착한 후 보호필름 탭을 벗겨내어 액정필름 하단면을 부착한다.The conventional method of attaching the liquid crystal protective film configured as above is to determine the attachment location by operator judgment, peel off the adhesive surface protective film tab, and temporarily attach the upper surface of the liquid crystal film to the upper liquid crystal of the mobile terminal, and then the protective film. Peel off the tab and attach the bottom of the liquid crystal film.
그런데 상기와 같이 구성된 액정필름 부착 작업은 숙련자여도 주관적으로 가늠하여 작업하기 때문에 부착 실패 확률이 생긴다.However, since the work of attaching the liquid crystal film configured as described above is subjectively measured even by skilled workers, there is a probability of failure of attachment.
이렇게 되면 작업자는 휴대단말기 디스플레이에서 액정필름을 다시 떼어 정확한 위치로 보정하는 과정에서 액정필름과 휴대단말기 디스플레이 사이에 먼지가 들어가거나 액정필름이 손상되는 문제점이 있었다.In this case, there is a problem that dust enters or damages the liquid crystal film between the liquid crystal film and the mobile terminal display in the process of correcting the liquid crystal film to the correct position by removing the liquid crystal film from the display of the mobile terminal.
또한, 종래 방법에서는 제1보호지-보호필름-제2보호지-대지의 4층필름으로 이루어지며 상기 보호필름에는 점착층이 마련된 1차필름 상의 제1보호지-보호필름-제2보호지에 커터기로 특정 패턴을 형성하는 제1패턴가공공정을 실시한다.In addition, in the conventional method, the first protective paper-protective film-second protective paper-earth four-layer film is formed, and the protective film is specified with a cutter on the first protective paper-protective film-second protective paper on the primary film provided with an adhesive layer. A first pattern processing step of forming a pattern is performed.
이후, 상기 1차필름의 패턴가공공정과 별도로 상부필름-하부필름-대지의 3층필름으로 이루어진 2차필름을 상기 1차필름과 동일한 패턴으로 커팅 가공함과 동시에 그 중앙부에는 커팅밴드부를 형성하는 제2패턴가공공정을 실시한다.Thereafter, separate from the pattern processing process of the primary film, a secondary film consisting of a three-layer film of the upper film-lower film-ground is cut into the same pattern as the primary film, and a cutting band is formed at the center thereof. Perform a second pattern processing process.
상기 제1,2패턴가공공정을 거친 1차필름 및 2차필름 상의 특정 커팅패턴을 정확히 얼라인시켜 접합시키기 위해 1차차필름에서는 제2보호지 및 대지를 제거하고 2차필름에서는 상부필름을 제거한 후 압착롤을 통과시키는 합지공정을 실시한다.In order to accurately align and bond specific cutting patterns on the primary and secondary films that have gone through the first and second pattern processing processes, the second protective paper and the site are removed from the primary film, and the upper film is removed from the secondary film. A lamination process is carried out through the pressing roll.
상기 합지공정에 의해 합지된 제1보호지-보호필름-하부필름-대지의 4층구조의 합지필름에서 대지를 제거하여 제1보호지-보호필름-커팅밴드부를 갖는 하부필름에 의한 3층 구조의 보호필름형성공정을 실시한다.Protection of the three-layer structure by the lower film having the first protective paper-protective film-cutting band by removing the paper from the laminated film of the four-layer structure of the first protective paper-protective film-lower film-substrate laminated by the laminating process Conduct a film forming process.
이와 같은 종래의 보호필름 제조방법은 1차필름의 패턴가공공정과 별도로 상부필름-하부필름-대지의 3층필름으로 이루어진 2차필름을 가공하는 공정이 추가되므로 제조공정이 매우 복잡한 문제가 있다. Such a conventional method for manufacturing a protective film has a problem that the manufacturing process is very complicated because a process of processing a secondary film composed of a three-layer film of an upper film-lower film-ground is added separately from the pattern processing process of the primary film.
