Field of the Invention The present invention relates to a method for manufacturing a liquid crystal display (LCD) module. In particular, the contact pads are not formed to easily identify contact pads of a transparent electrode pattern formed on a liquid crystal substrate. The present invention relates to a method of manufacturing an LCD module which can prevent misalignment with a connecting means for forming an insulating coating film on a liquid crystal substrate and connecting with external terminals during an assembly process.
평판표시장치의 일종인 LCD는 액체의 유동성과 결정의 광학적 성격을 겸비하는 액정에 전계를 가하여 광학적 이방성을 변화시키는 장치로서, 종래 음극선관(Cathode Ray Tube)에 비해 소비전력이 낮고, 경박단소화가 용이하며 대형화 및 고정세화가 가능하여 널리 사용되고 있다.LCD, which is a kind of flat panel display device, changes the optical anisotropy by applying an electric field to the liquid crystal that combines the liquidity of liquid and the optical characteristics of crystal.It has lower power consumption and light and small size than conventional cathode ray tube. It is easy to use and is widely used because of its large size and high definition.
일반적으로 LCD는 투명전극 패턴과 화소전극이 스위칭 소자와 연결되는 하측 액정기판과 공통전극이 형성되어 있는 상측 액정기판이 실패턴 및 스페이서에 의해 접착되고 그 사이의 공간에 액정이 밀봉되어 이러는 형태로 구성된다.In general, LCDs are formed in such a way that a transparent liquid crystal pattern, a lower liquid crystal substrate on which a pixel electrode is connected to a switching element, and an upper liquid crystal substrate on which a common electrode is formed are bonded by a failure turn and a spacer, and a liquid crystal is sealed in a space therebetween. It is composed.

Are formed. In this case, after a failure turn is formed between the display area and the contact pads to seal another liquid crystal substrate, for example, an upper liquid crystal substrate on which a common electrode is formed, the contact pads are formed between a zebra-type anisotropic conductive rubber or an insulating film. A heat seal in which metal wiring is formed is connected to the terminals of the printed circuit board.
그런데 상기와 같은 종래의 액정기판은 접촉패드들 간의 간격 즉 패드 스페이스가 어느정도 이하로 좁아지면 패턴의 식별이 어려워 LCD 모듈로 조립할 때, 외부단자와의 오정열에 따른 단락 또는 단선등이 발생하기 쉬워 공정수율 및 소자동작의 신회성이 떨어지는 문제점이 있다.However, in the conventional liquid crystal substrate as described above, when the distance between the contact pads, i.e., the pad space is narrowed to a certain level or less, the pattern is difficult to be identified. There is a problem that the yield and the reliability of the device operation is poor.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 본발명의 목적은 액정기판상에 투명전극 패턴을 형성하고, 상기 투명전극 패턴과 연결되어 외부단자와 접촉되는 접촉패드들을 액정기판의 일측에 형성하고, 상기 접촉패드들이 형성되어 있지 않은 액정기판 상에 상기 투명전극 패턴보다 얇은 두께로 절연도료막을 도포하여 패턴 식별을 용이하게 하여 모듈 조립공정시의 오정렬을 방지하므로서 조립 공정시의 공정수율 및 소자동작의 신뢰성을 향상시킬 수 있는 LCD 모듈의 제조방법을 제공함에 있다.The present invention is to solve the above problems, an object of the present invention is to form a transparent electrode pattern on the liquid crystal substrate, the contact pads which are connected to the transparent electrode pattern in contact with the external terminal is formed on one side of the liquid crystal substrate In addition, by coating an insulating coating film with a thickness thinner than that of the transparent electrode pattern on the liquid crystal substrate on which the contact pads are not formed, pattern identification is facilitated, thereby preventing misalignment during the assembly process. It is to provide a method for manufacturing an LCD module that can improve the reliability of the operation.

이하, 본 발명에 따른 LCD 모듈의 제조 방법에 관하여 첨부도면을 참조하여 상세히 설명한다.Hereinafter, a method of manufacturing an LCD module according to the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본밥명에 따른 LCD 모듈의 제조방법을 설명하기 위한 개략도로서, 액정기판상에 절연 도료막이 도포된 상태의 예이다.1 is a schematic view for explaining a method of manufacturing an LCD module according to the present invention, which is an example of a state in which an insulating coating film is coated on a liquid crystal substrate.
먼저, 투명재질, 예를 들어 석영재질의 액정기판(1) 일측에서 영상이 표시되는 디스플레이 영역(2)으로 예정되어 이러는 부분상에 화소전극등의 투명전극 패턴(3)들을 형성하고, 상기 액정기판(1)의 타측에는 상기 투명전극 패턴(3)들을 외부 단자(도시되지 않음)들과 연결시키는 접촉패드(4)들을 형성한다. 여기서 상기 접촉패드(4)들은 투명전극 패턴(3)와 함께 형성하거나 따로 형성할 수도 있다.First, a transparent area, for example, a display area 2 in which an image is displayed on one side of a liquid crystal substrate 1 of quartz material, is formed, and on this part, transparent electrode patterns 3 such as pixel electrodes are formed, and the liquid crystal Contact pads 4 are formed on the other side of the substrate 1 to connect the transparent electrode patterns 3 to external terminals (not shown). The contact pads 4 may be formed together with the transparent electrode pattern 3 or may be formed separately.
그다음 상기 액정기판(1)의 일측에 일렬로 배열되어 있는 접촉패드(4)들 사이의 액정기판(1)상에 스크린 프린트등의 방법으로 절연도료막(5)을 형성한 후, 상기 액정기판(1) 상에 절연막 및 배향막을 순차적으로 형성하고, 액정을 일정한 방향으로 배향시키기 위한 러빙 공정을 실시하여 액정기판을 완성한다. 이때 상기 절연도료막(5)은 후속 모듈 조립 공정시의 접촉패드(4)와 외부단자와의 접촉성을 고려하여 상기 투명전극 패턴(3) 보다 얇은 두께로 형성한다.Then, the insulating coating film 5 is formed on the liquid crystal substrate 1 between the contact pads 4 arranged in one line on one side of the liquid crystal substrate 1 by screen printing or the like, and then the liquid crystal substrate is formed. (1) An insulating film and an alignment film are formed sequentially, and the rubbing process for orienting a liquid crystal in a fixed direction is performed, and a liquid crystal substrate is completed. At this time, the insulating coating film 5 is formed to a thickness thinner than the transparent electrode pattern 3 in consideration of the contact between the contact pad 4 and the external terminal in the subsequent module assembly process.
그후, 아라기 액정기판(1)의 디스플레이 영역(2)과 접촉패드(4)들의 사이에 실 패턴(6)을 형성한 후, 다른 액정기판, 예를들어 공통전극이 형성되어 있는 상측 액정기판과 접착시키고, 액정을 주입한 후, 밀봉하여 LCD 판넬을 완성한다.Thereafter, the seal pattern 6 is formed between the display area 2 of the Aragi liquid crystal substrate 1 and the contact pads 4, and then another liquid crystal substrate, for example, an upper liquid crystal substrate on which a common electrode is formed. And liquid crystal are injected and then sealed to complete the LCD panel.
상기와 같이 형성된 LCD 판넬을 사각 틀체 그리하여 상의 모듈 홀더에 탑재한 후, 제브라형 이방성 도전 고무나 히트실등의 열결수단과 접촉패드(4)들을 정렬시켜 접착하고, 인쇄회로 기판과 백라이트를 탑재하여 LCD 모듈을 완성한다. 이때 상기 절연도료막(5)에 의해 투명전극 패턴(3)의 인식이 용이하여 정렬 공정의 신뢰성이 향상된다.After mounting the LCD panel formed as described above in the rectangular holder and the module holder on the top, the thermal contact means such as zebra type anisotropic conductive rubber or heat seal and the contact pads 4 are aligned and bonded, and the printed circuit board and the backlight are mounted. Complete the LCD module. At this time, the insulating coating film 5 facilitates the recognition of the transparent electrode pattern 3, thereby improving the reliability of the alignment process.
이상에서 설명한 바와 같이, 본발명에 따른 LCD 모듈의 제조방법은 액정기판상에 형성되어 있는 투명전극 패턴과 연결되어 외부단자와 접촉되는 접촉패드들을 액정기판의 일측에 형성한 후, 상기 접촉패드들 사이의 액정기판 일측에 절연 도료막을 형성하고 후속 공정을 진행하여 LCD 판넬을 형성하며, 상기의 LCD 판넬을 제브라형 이방성 도전고무나 히트실을 사용하여 외부 단자와 연결하고 모듈홀더등과 조립하여 LCD 모듈을 형성하였으므로, 조립 공정시 상기 접촉단자의 패턴 인식이 용이하여 접촉 공정시의 오정렬에 의한 단락 및 단선등의 불량을 방지하여 공정수율 및 소자동작의 신뢰성을 향상시킬 수 있는 이점이 있다.As described above, in the LCD module manufacturing method according to the present invention, contact pads connected to a transparent electrode pattern formed on a liquid crystal substrate and contacting external terminals are formed on one side of the liquid crystal substrate, and then the contact pads are formed. Form an insulating paint film on one side of the liquid crystal substrate and proceed to the subsequent process to form an LCD panel.Connect the LCD panel with an external terminal using a zebra-type anisotropic conductive rubber or heat seal and assemble it with a module holder. Since the module is formed, it is easy to recognize the pattern of the contact terminal during the assembly process, thereby preventing short circuits and disconnections due to misalignment during the contact process, thereby improving process yield and device operation reliability.
