본 발명은 구동회로의 전압 시그널을 액정 디스플레이의 전극으로 전달하기 위하여, 구동회로기판과 액정 디스플레이의 사이에 연결되는 액정 디스플레이 모듈의 배선 실장방법에 관한 것이다.The present invention relates to a wiring mounting method of a liquid crystal display module connected between a driving circuit board and a liquid crystal display in order to transfer a voltage signal of the driving circuit to an electrode of the liquid crystal display.

액정 디스플레이는 외부로부터 인가되는 전압에 의해 액정의 꼬임각이 변화되는 유전이방성을 이용하여, 백라이트 혹은 외부로부터 조사된 광(光)을 선택적으로 투과시키거나 반대로 투과되지 않게 함으로써 문자나 숫자 및 화상을 표시한다.The liquid crystal display uses dielectric anisotropy in which the twist angle of the liquid crystal is changed by a voltage applied from the outside to selectively transmit or reverse the letters, numbers, and images through the backlight or the light irradiated from the outside. Display.

이러한 액정 디스플레이는 평행하게 배치된 투명한 2매의 글라스기판에 ITO(Induim Tin Oxide) 투명전극을 형성하고, 그 상측에 액정의 유전이방성을 한정하는 배향막을 적층하며, 이렇게 형성된 2매의 글라스기판을 실링하고 그 사이공간에 액정을 주입 밀봉하여 구성한다. 또 2매의 글라스기판의 외측면에는 실제적으로 디스플레이의 효과를 얻기 위해, 백라이트의 광을 선편광시켜 주는 편광판을 부착하여 이루어진다.Such a liquid crystal display forms an ITO (Induim Tin Oxide) transparent electrode on two transparent glass substrates arranged in parallel, and laminates an alignment layer defining dielectric anisotropy of the liquid crystal on the upper side thereof. It is constructed by sealing and injecting and sealing liquid crystal in the space therebetween. Moreover, in order to obtain the effect of a display, the polarizing plate which linearly polarizes the light of a backlight is attached to the outer surface of two glass substrates.

도 2에 도시한 바와 같이, 상기한 액정 디스플레이(2)는 백라이트(4) 및 구동 LSI을 포함하는 구동회로기판(6)과 함께 베젤(8)을 이용하여 조립되어서 모듈화 된다. 이때 구동회로기판(6)과 액정 디스플레이(2)의 사이에는 구동회로의 시그널을 전달하기 위해, 열압착 배선(heat seal)(10) 및 제브라 컨넥터(12)를 연결하는데, 이러한 접속 조합방식은 QFD 모듈 방식으로 잘 알려져 있다.As shown in Fig. 2, the liquid crystal display 2 is assembled and modularized using a bezel 8 together with a driving circuit board 6 including a backlight 4 and a driving LSI. At this time, the heat seal 10 and the zebra connector 12 are connected between the driving circuit board 6 and the liquid crystal display 2 in order to transmit a signal of the driving circuit. It is well known for its QFD modular approach.

여기서 상기한 열압착 배선(10)은 베이스 필름으로 폴리에스터를 사용하고, 도전성 도료를 스크린 인쇄하여 도전라인을 형성하며, 그 도전라인의 상부에 금속입자가 분산된 전연성의 핫 멜트 접착제층을 도포하여 형성한다.Here, the thermally crimped wiring 10 uses polyester as a base film, screen-prints a conductive paint to form a conductive line, and applies a malleable hot melt adhesive layer in which metal particles are dispersed on top of the conductive line. To form.

이렇게 형성된 열압착 배선(10)은 도 3에 도시한 바와 같이, 구동회로기판(6)의 패드(6a)와 액정 디스플레이(2)의 전극 패드(2a)에 각각 단부를 올려놓고 열압착하여 간단하게 실장 및 접속할 수 있다. 이때 열압착 배선(10)의 일면에는 액정 디스플레이(2) 및 구동회로기판(6)과의 절연 및 접촉을 방지하기 위해 보호필름(14)을 부착한다.As shown in FIG. 3, the thermocompression wiring 10 thus formed is simply formed by placing an end portion on the pad 6a of the driving circuit board 6 and the electrode pad 2a of the liquid crystal display 2. Can be mounted and connected. In this case, a protective film 14 is attached to one surface of the thermocompression wiring 10 to prevent insulation and contact with the liquid crystal display 2 and the driving circuit board 6.

그러나 종래의 액정 디스플레이 모듈에 의하면, 열압착 배선(10)의 길이가 길거나 짧게 형성된 경우에는 액정 디스플레이(2)의 전극 패드(2a) 및 구동회로기판(6)의 패드(6a)와 열압착 배선(10)의 결합력(통상 400 g/㎝)이 약하기 때문에, 약한 외부 충격이나 복원력에 의해 쉽게 분리되어 제품 불량을 초래하는 문제점이 있다.However, according to the conventional liquid crystal display module, when the length of the thermocompression wiring 10 is long or short, the electrode pad 2a of the liquid crystal display 2 and the pad 6a and the thermocompression wiring of the driving circuit board 6 are formed. Since the bonding force (typically 400 g / cm) of (10) is weak, there is a problem of being easily separated by a weak external impact or restoring force, resulting in product defects.

예를 들어 상기 열압착 배선(10)과 액정 디스플레이(2)의 전극 패드(2a) 및 구동회로기판(6)의 패드(6a)가 분리되는 원인으로는, 열압착 배선(10)의 길이가 짧은 경우 약한 충격에도 인장력이 발생하여 쉽게 손상되는 것이며, 또한 열압착 배선(10)의 길이가 긴 경우에는 보호 필름(14)에 의해 발생하는 지속적인 복원력(도 3의 화살표 방향)에 의해 발생한다.For example, the reason that the thermocompression wiring 10 is separated from the electrode pad 2a of the liquid crystal display 2 and the pad 6a of the driving circuit board 6 is long. In the shorter case, a tensile force is generated even in a weak impact and is easily damaged. In addition, when the length of the thermocompression wiring 10 is long, it is generated by the continuous restoring force (arrow direction in FIG. 3) generated by the protective film 14.

앞서 설명한 종래 기술의 문제점을 해결하기 위한 것으로서, 본 발명은 구동회로기판 및 액정 디스플레이의 사이에 연결되는 열압착 배선의 길이를 최적화하여, 열압착 배선의 분리 및 그에 따른 제품 불량을 해소할 수 있도록 하는 액정 디스플레이 모듈의 배선 실장방법을 제공함에 그 목적을 두고 있다.In order to solve the problems of the prior art described above, the present invention is to optimize the length of the thermocompression wiring connected between the driving circuit board and the liquid crystal display, so that the separation of the thermocompression wiring and the resulting product defects can be solved. An object of the present invention is to provide a wiring mounting method of a liquid crystal display module.

이에 따라 본 발명에서는 구동회로기판의 패드와 액정 디스플레이의 전극 패드 사이에 구동회로의 시그널을 전달하는 열압착 배선을 실장함에 있어서, 상기 열압착 배선의 길이(L)를

식을 만족하는 길이로 형성함을 특징으로 한다.Accordingly, in the present invention, in mounting the thermocompression wiring for transmitting the signal of the driving circuit between the pad of the driving circuit board and the electrode pad of the liquid crystal display, the length L of the thermocompression wiring is determined.

또 본 발명에서는 열압착 배선의 길이(L)에 액정 디스플레이와 구동회로기판의 어긋난 길이(±W)를 가감하여 최적 설계를 할 수 있다.
In the present invention, the optimum length can be achieved by subtracting the offset length (± W) of the liquid crystal display and the driving circuit board to the length L of the thermocompression wiring.

이하, 본 발명을 실현하기 위한 바람직한 실시예를 첨부 도면에 의거하여 보다 상세하게 설명한다. 참고로 본 발명을 설명함에 있어서 종래의 구성과 동일한 부분에 대하여는 동일 부호를 부여하기로 한다.EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment for implementing this invention is demonstrated in detail based on an accompanying drawing. For reference, in describing the present invention, the same reference numerals will be given to the same parts as the conventional configurations.

도 1은 본 발명의 액정 디스플레이 모듈의 배선 실장방법을 보여주고 있다.1 shows a wiring mounting method of a liquid crystal display module of the present invention.

도시한 바와 같이 본 발명에서는 구동회로기판(6)의 패드(6a)와 액정 디스플레이(2)의 전극 패드(2a) 사이에 열압착 배선(100)을 연결하여서, 구동회로에서 인가되는 시그널을 전달한다.As shown in the figure, the thermocompression wiring 100 is connected between the pad 6a of the driving circuit board 6 and the electrode pad 2a of the liquid crystal display 2 to transmit a signal applied from the driving circuit. do.

본 발명에서 열압착 배선(100)은 폴리에스터로 된 베이스 필름(102)의 상부에 도전성 도료를 인쇄하여 도전라인(104)을 형성하고, 그 상부에 전연성의 핫 멜트 접착제층(106)을 형성하여 이루어지며, 그 일면에 보호 필름(14)을 부착하고 있다.In the present invention, the thermocompression wiring 100 forms a conductive line 104 by printing a conductive paint on the base film 102 made of polyester, and forms a malleable hot melt adhesive layer 106 thereon. The protective film 14 is attached to one surface thereof.

이렇게 구성된 본 발명의 열압착 배선(100)은 짧거나 긴 경우에 발생하는 외부 충격력이나 복원력에 의한 종래 기술의 문제점을 해결하기 위한 수단으로, 상기 열압착 배선(100)의 길이(L)를 최적화하여 외부 충격력이나 복원력에 의한 영향을 제거함을 특징으로 한다.The thermocompression wiring 100 according to the present invention configured as described above is a means for solving the problems of the prior art due to the external impact force or the restoring force that occurs when the short or long, and optimizes the length L of the thermocompression wiring 100. It is characterized by removing the influence of external impact force or restoring force.

이를 위하여 본 발명에서는 열압착 배선(100)의 길이를 설계함에 있어서, 식

Figure 112000008312031-pat00003
을 만족하도록 형성한다.To this end, in the present invention in designing the length of the thermocompression wiring 100,

Form to satisfy.

상기 식에서 Whl은 액정 디스플레이(2)의 전극 패드(2a)에 결합되는 열압착 배선의 길이이고, Whp는 구동회로기판(6)의 패드(6a)에 결합되는 열압착 배선의 길이이며, H는 액정 디스플레이(2)와 구동회로기판(6)의 사이 간격을 나타낸다.In the above formula, Whl is the length of the thermocompression wiring coupled to the electrode pad 2a of the liquid crystal display 2, and Whp is the length of the thermocompression wiring coupled to the pad 6a of the driving circuit board 6, where H is The distance between the liquid crystal display 2 and the driving circuit board 6 is shown.

여기서 액정 디스플레이(2)와 구동회로기판(6)의 사이 간격 H는 그 사이에 제브라 컨넥터를 설치할 경우에는 그 제브라 컨넥터의 높이가 되며, 이때 상기 액정 디스플레이(2)와 구동회로기판(6)의 사이 간격 H는 상기 식의 최적화를 위하여 0mm 내지 6㎜로 설정하는 것이 좋다. 예를 들어 상기 액정 디스플레이(2)와 구동회로기판(6)의 사이 간격 H가 6㎜ 이상일 경우에는 상기 식의 정확도가 다소 떨어질 수 있다.Here, the distance H between the liquid crystal display 2 and the driving circuit board 6 is the height of the zebra connector when the zebra connector is installed therebetween, wherein the liquid crystal display 2 and the driving circuit board 6 The interval H is preferably set to 0 mm to 6 mm for optimization of the above equation. For example, when the distance H between the liquid crystal display 2 and the driving circuit board 6 is 6 mm or more, the accuracy of the above equation may be somewhat lower.

또 본 발명에서는 열압착 배선(100)의 길이(L)를 설정할 때 고려할 사항으로, 액정 디스플레이(2)와 구동회로기판(6)의 어긋난 길이(±W)를 가감하여야 한다. 이때 열압착 배선(100)의 길이(L)는 액정 디스플레이(2)와 구동회로기판(6)이 도면의 우측으로 어긋날 경우 상기 식에서 해당 길이(W)를 감하고, 도면의 좌측으로 어긋날 경우에는 상기 식에서 해당 길이(W)를 가하여 전체 길이를 설계한다.In addition, in the present invention, when setting the length L of the thermocompression wiring 100, the shifted length (± W) of the liquid crystal display 2 and the driving circuit board 6 should be added or subtracted. At this time, the length L of the thermocompression wiring 100 subtracts the corresponding length W from the above equation when the liquid crystal display 2 and the driving circuit board 6 are shifted to the right side of the drawing, and the length L of the thermocompression wiring 100 is shifted to the left side of the drawing. The total length is designed by adding the corresponding length (W) in the above equation.

이와 같이 형성된 본 발명의 열압착 배선(100)은 구동회로기판(6)의 패드(6a)와 액정 디스플레이(2)의 전극 패드(2a)의 사이에서 실장되어서 구동 및 전압 시그널을 전달하고, 액정 디스플레이의 상·하 전극 사이에 주입된 액정을 트위스트되게 함으로써, 백라이트로부터 조사된 빛을 선택적으로 투과시켜 문자나 숫자 혹은 기타 임의의 아이콘을 표시한다.The thermocompression wiring 100 according to the present invention formed as described above is mounted between the pad 6a of the driving circuit board 6 and the electrode pad 2a of the liquid crystal display 2 to transmit driving and voltage signals, By twisting the liquid crystal injected between the upper and lower electrodes of the display, the light irradiated from the backlight is selectively transmitted to display letters, numbers, or any other icons.
