종래기술에 따른 휴대폰의 LCD창 제조방법은 금속증착면 에칭시 강산 도는 강알카리 화학물질을 사용해야하므로 작업이 위험하고 폐수처리가 불편할 뿐만 아니라 환경오염이 심한 문제점이 있었다. LCD window manufacturing method of the mobile phone according to the prior art has to use a strong alkali chemicals strong acidity when etching the metal deposition surface, which is dangerous work and inconvenient wastewater treatment, there was a serious environmental pollution.

본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위한 것으로, 그 목적은 휴대폰 등의 LCD 창 제조를 위하여 아크릴 원판에 문자/라인을 베다 및 실크스크린 인쇄하고, 마스킹 잉크인쇄와 금속증착 후 마스킹 잉크를 수세식 또는 테이프식으로 제거하므로 화학물질 사용에 따른 문제점을 해소하도록 하는 마스킹방법에 의한 LCD 창 제조방법을 제공함에 있다.
The present invention is to solve the above-mentioned problems of the prior art, the purpose is to cut the character / line and silk-screen printing on the acrylic disc for the manufacture of LCD windows of mobile phones, masking ink printing and masking ink after metal deposition The present invention provides a method for manufacturing an LCD window by a masking method to eliminate the problem caused by the use of chemicals by removing the flush or tape method.

본 발명의 목적을 달성하기 위한 본 발명에 따른 마스킹방법에 의한 LCD창 제조과정은 소정크기로 절단된 아크릴에 문자/라인을 베다 및 실크스크린 인쇄하고, 금속증착 후 필요한 부분 이외는 제거하고, 후도인쇄 및 로고/문자 홀로그램 스탬핑과정을 통해 액정표시장치의 창을 제조하는 방법에 있어서, 상기 문자/라인이 인쇄된 아크릴 표면 일정영역을 마스킹 잉크 인쇄하는 마스크인쇄단계와, 상기 마스크 인쇄된 아크릴 전체 표면에 금속증착하는 금속증착단계와, 상기 금속증착된 아크릴 표면에 마스크 인쇄된 잉크 부분을 박리 제거하는 마스킹잉크제거단계를 포함하여 이루어진 것을 특징으로 한다.LCD window manufacturing process by the masking method according to the present invention for achieving the object of the present invention to cut the character / line and acrylic screen printing on the acrylic cut to a predetermined size, after removing the necessary parts after metal deposition, after A method of manufacturing a window of a liquid crystal display device through printing and logo / character hologram stamping, the method comprising: a mask printing step of masking ink printing a predetermined area of an acrylic surface on which the letter / line is printed; and the entire mask-printed acrylic And a masking ink removing step of peeling and removing a mask-printed ink portion on the metal-deposited acrylic surface.

이와 같이 이루어진 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 여기서, 종래 기술과 동일한 부분에 대해서는 동일 부호를 부여하고 그 상세한 설명은 생략한다.The present invention made as described above will be described in detail with reference to the accompanying drawings. Here, the same parts as in the prior art are denoted by the same reference numerals and detailed description thereof will be omitted.

도 2a 내지 도 2f는 본 발명의 일 실시 예에 따른 마스크방법에 의한 LCD 창 제조과정을 설명하기 위한 제조 순서에 따른 각 층의 표시도이다.2A to 2F are display diagrams of each layer according to a manufacturing procedure for explaining an LCD window manufacturing process by a mask method according to an embodiment of the present invention.

도 3은 본 발명의 실시예에 따른 마스크방법에 의한 LCD 창 제조과정의 흐름도이다.3 is a flowchart of an LCD window manufacturing process by a mask method according to an embodiment of the present invention.

이에 도시된 바와 같이 먼저, 아크릴 원판(10)을 일정크기로 절단한다(S102)As shown in the drawing, first, the acrylic disc 10 is cut into a predetermined size (S102).

상기 절단된 아크릴 표면에 문자 및 라인을 베다 또는 실크스크린 인쇄(Positive)를 하여 문자/라인 인쇄층(12)을 형성한다.(S104)Character / line printing layer 12 is formed by cutting letters and lines on the cut acrylic surface or by silkscreen printing (S104).

상기 아크릴(10) 표면 일정 영역을 마스킹 잉크 인쇄를 하여 마스크인쇄층(104)를 형성한다.(S106) 이때 마스크 인쇄는 포지티브(Positive) 또는 네거티브(Negative)를 선택 인쇄한다.The mask printing layer 104 is formed by masking ink printing on a predetermined area of the surface of the acrylic 10 (S106). In this case, the mask printing selectively prints positive or negative.

상기 문자/라인 인쇄층(12)과 상기 마스크인쇄층(104)를 포함한 아크릴(10) 전체 표면을 소정 금속으로 증착하여 금속증착층(106)을 형성한다.(S108)A metal deposition layer 106 is formed by depositing the entire surface of the acrylic 10 including the character / line printed layer 12 and the mask printed layer 104 with a predetermined metal.

다음은 마스크인쇄층(104)을 제거하게 되는데, 상기 마스크인쇄층(104) 상부에 증착된 금속증착층(106)과 함께 박리되어 제거된다.(S110)Next, the mask print layer 104 is removed, and the mask print layer 104 is peeled off and removed together with the metal deposition layer 106 deposited on the mask print layer 104.

이때, 도 2e에 도시된 바와 같이 금속증착층(106)과 아크릴(10)의 층간 'A'부분은 접착력이 강하고, 상기 금속증착층(106)과 마스크인쇄층(104)의 층간 'B'는 접착력이 강하고, 상기 마스크인쇄층(104)와 아크릴(10)의 층간 'C'은 접착력이 약 하여 마스크인쇄층(104) 및 그 영역에 해당하는 금속증착층 영역이 박리 제거된다. In this case, as shown in FIG. 2E, the interlayer 'A' portion of the metal deposition layer 106 and the acrylic 10 has strong adhesion, and the interlayer 'B' of the metal deposition layer 106 and the mask printing layer 104 is strong. The adhesive strength is strong, and the interlayer 'C' of the mask printing layer 104 and the acrylic 10 has a weak adhesive force, so that the mask printing layer 104 and the metal deposition layer region corresponding to the region are peeled off.

여기서, 마스크인쇄층(104) 상부에 증착된 금속증착층(106)영역은 100Å~200Å 정도로 매우 얇아서 제거되는 금속증착층(106) 측면에 손상을 주지 않고 박리제거할 수 있다.Here, the region of the metal deposition layer 106 deposited on the mask printing layer 104 is very thin, such as 100 ~ 200 ~ can be removed without damaging the side of the metal deposition layer 106 is removed.

상기 마스크인쇄층(104) 제거방법은 마스킹 잉크가 수용성이기 때문에 고압 수세장치를 이용하여 고압의 물로 세척하므로 제거가 가능하다.Since the masking ink is water-soluble, the mask printing layer 104 may be removed by washing with high pressure water using a high pressure washing apparatus.

상기 마스크인쇄층(104)를 제거하기 위한 다른 방법은 상기 금속증착층 표면에 접착 테이프를 접착한 후 떼어내므로 상기 마스크인쇄층(104)와 그 상부에 증착된 금속증착층(106)이 상기 접착테이프와 함께 박리 제거된다.Another method for removing the mask printing layer 104 is to remove the mask printing layer 104 by adhering the adhesive tape to the surface of the metal deposition layer, and thus removing the mask printing layer 104 and the metal deposition layer 106 deposited thereon. It is peeled off together with the adhesive tape.

이와같이 금속증착 및 마스크 인쇄층을 화학약품을 사용하지 않고 물 또는 접착 테이프를 이용하여 간단히 제거할 수 있게 된다.As such, the metal deposition and mask printed layers can be easily removed using water or adhesive tape without using chemicals.

상기 과정을 통해 마스크인쇄층(104)이 제거한 후 1차 후도인쇄, 로고 및 문자 등 호로그램 스탬핑, 2차 후도인쇄 와 외형가공공정을 통해 LCD 창을 제조하게 된다.(S112 ~ S118)After the mask print layer 104 is removed through the above process, the LCD window is manufactured through first post-printing, logo stamping such as logos and letters, second post-printing, and external processing. (S112 to S118)

이상에서 본 발명에 따른 바람직한 실시예에 대해 설명하였으나, 마스킹 잉크 인쇄 또는 마스크인쇄층 제거방법에 따라 다양한 형태으로 변형이 가능하며, 본 기술분야에서 통상의 지식을 가진자라면 본 발명의 특허청구범위를 벗어남이 없이 다양한 변형예 및 수정예를 실시할 수 있을 것으로 이해된다. Although a preferred embodiment according to the present invention has been described above, the present invention may be modified in various forms according to a masking ink printing or mask printing layer removing method, and a person skilled in the art may claim the present invention. It is understood that various modifications and variations can be made without departing from the scope of the invention.

이상에서 설명한 바와 같이, 본 발명에 따른 마스크인쇄방법에 의한 LCD 창 제조장법은 라인 및 배면 금속증착시 수용성 마스킹 잉크 및 물 세척 또는 접착테이프를 이용하여 제거하므로 강산 또는 강알카리성 화학약품을 이용한 에칭과정이 필요없어 작업이 간단하고 안전하며, 그에 따라 폐수처리 등의 환경오염의 요소가 제거되는 효과가 있다. As described above, the LCD window manufacturing method by the mask printing method according to the present invention is removed by using a water-soluble masking ink and water washing or adhesive tape during the deposition of line and back metal, so that the etching process using a strong acid or strong alkaline chemicals This operation is simple and safe because it is not necessary, and thus there is an effect of removing elements of environmental pollution such as wastewater treatment.
