[산업상의 이용분야][Industrial use]
본 고안은 액정 표시 장치용 모듈 구조에 관한 것으로서, 보다 상세하게는 액정표시소자와 제1기판을 탭방식으로 부착하여 하우징에 수납시 플렉시블 와이어를 구부려 하우징의 배면에 밀착시킴에 따라 액정표시소자와 플렉시블 와이어 또는 플렉시블 와이어와 기판의 접촉 불량을 방지할 수 있는 액정 표시 장치용 모듈 구조에 관한 것이다.The present invention relates to a module structure for a liquid crystal display device, and more particularly, a liquid crystal display device and a first substrate are attached in a tab manner, and the flexible wire is bent in contact with the rear surface of the housing when the housing is housed in the housing. The present invention relates to a module structure for a liquid crystal display device capable of preventing poor contact between a flexible wire or a flexible wire and a substrate.
[종래의 기술][Prior art]
일반적으로, 평판 표시 장치는 형광 표시판(VFD)과 액정표시장치(LCD) 그리고 전계방출소자(EL)와 플라즈마 표시장치(PDP) 등으로 구분되는 바, 상기한 액정표시장치는 외부의 미약한 전압변화에 의해 액정의 배열이 변화됨으로 인하여 상기한 액정의 저면에 위치된 백 라이트의 광선을 선택 투과시켜 소정의 표시를 행하게 된다.In general, a flat panel display is classified into a fluorescent display panel (VFD), a liquid crystal display (LCD), a field emission device (EL), a plasma display device (PDP), and the like. As the arrangement of the liquid crystal is changed by the change, predetermined display is performed by selectively transmitting the light rays of the backlight located on the bottom surface of the liquid crystal.
상기한 액정표시장치는 통상 액정표시소자와 드라이버 칩과의 연결을 콥(COB), 탭(TAB), 콕(COG) 방식으로 사용하는 바, 상기한 다수의 연결 방식 중 콥방식은 미세한 패턴의 형성이 어렵고 콕방식은 미세한 패턴 형성이 용이한 반면 제작이 어렵기 때문에 통상 탭방식을 사용하게 된다.The liquid crystal display device typically uses a connection between a liquid crystal display device and a driver chip in a COB, TAB, and COG method. Among the plurality of connection methods, the COB method has a fine pattern. Difficult to form and the cock method is easy to form a fine pattern, while the production is difficult because the tab is usually used.
여기서, 상기한 탭방식의 액정표시장치는 제3도에 도시된 바와 같이 상, 하 패널(50,51)이 접합된 액정표시소자(52)에 드라이버 칩(53)이 내장된 플렉시블 와이어(54)가 외부신호가 인가되는 제1, 2기판(55,56)에 연결되어 있고 이는 도시되지 않은 베젤과 하우징에 수납되어 있는 구성으로 형성된다.Here, in the tab type liquid crystal display device, as shown in FIG. 3, the flexible wire 54 having the driver chip 53 built into the liquid crystal display device 52 to which the upper and lower panels 50 and 51 are bonded is provided. ) Is connected to the first and second substrates 55 and 56 to which an external signal is applied, which is formed in a bezel and a housing not shown.
물론, 상기한 액정표시소자(52)에는 상, 하 패널(50,51)에 각각 형성된 전극(미도시)이 겹쳐짐으로써 형성된 매트릭스 전극(57)이 형성되어 있게 된다.Of course, the liquid crystal display device 52 has a matrix electrode 57 formed by overlapping electrodes (not shown) formed on the upper and lower panels 50 and 51, respectively.
여기서, 상기한 제2기판(56)은 하우징에 안착된 상태이고 제1기판(55)은 액정표시장치의 면적을 감소시키기 위하여 구부러진 상태로 하우징의 저면에 밀착되는 바, 이는 제4도에 도시된 바와 같이 하우징(58)에 액정표시소자(52)와 백 라이트(59)가 순차 적층되어 있고 상기한 액정표시소자(52)에 플렉시블 와이어(54)로 연결된 제1기판(55)은 구부려져 하우징(58)의 저면에 밀착되어 있으며 이는 통상의 나사(60) 등으로 하우징(58)에 고정되어 있고 상기한 하우징(58)과 베젤(61)이 결합되어 전체를 고정하고 있다.Here, the second substrate 56 is seated on the housing and the first substrate 55 is in a bent state in order to reduce the area of the liquid crystal display, which is in close contact with the bottom of the housing, which is illustrated in FIG. As described above, the liquid crystal display device 52 and the backlight 59 are sequentially stacked on the housing 58, and the first substrate 55 connected to the liquid crystal display device 52 by the flexible wire 54 is bent. It is in close contact with the bottom of the housing 58, which is fixed to the housing 58 with a conventional screw 60 or the like, and the housing 58 and the bezel 61 are combined to fix the whole.
상기한 바와 같이 제1기판(55)을 하우징(58)의 저면에 밀착시킬 때 액정표시소자(52)와 플렉시블 와이어(54)의 분리를 방지하고 백 라이트(59)와 액정표시소자(52)의 이격 거리를 확보하기 위하여 하우징(58)과의 사이에 더미 제브라(62)를 삽입하게 된다.As described above, when the first substrate 55 is in close contact with the bottom surface of the housing 58, the separation of the liquid crystal display device 52 and the flexible wire 54 is prevented, and the backlight 59 and the liquid crystal display device 52 are prevented. The dummy zebra 62 is inserted between the housing 58 in order to secure the separation distance of the housing 58.
[고안이 해결하려고 하는 문제점][Problem trying to solve]
그러나, 상기한 바와 같이 액정표시소자(52)와 제1기판(55)을 플렉시블 와이어(54)로 연결하고 액정표시장치의 면적을 감소시키기 위하여 이를 하우징(58)의 저면에 밀착시킴은 플렉시블 와이어(54)가 구부러질 때 액정표시소자(52)와 제1기판(55)의 접합부에서 분리가 발생되어 액정표시장치에 결합이 발생되는 문제점이 있었다.However, as described above, in order to connect the liquid crystal display device 52 and the first substrate 55 with the flexible wire 54 and to reduce the area of the liquid crystal display device, the flexible wire is closely attached to the bottom surface of the housing 58. When the 54 is bent, separation occurs at the junction between the liquid crystal display device 52 and the first substrate 55, causing coupling to the liquid crystal display device.
또한, 상기한 바와 같이 제1기판(55)을 구부려 하우징(58)의 저면에 형성함은 구부리는 작업시 제1기판(55)과 액정표시소자(52)에 연결된 플렉시블 와이어(54)가 분리되지 않도록 주의를 요하기 때문에 작업 공정이 복잡하고 능률이 저하되는 문제점이 있다.In addition, as described above, the first substrate 55 is bent to be formed on the bottom surface of the housing 58. In the bending operation, the first substrate 55 and the flexible wire 54 connected to the liquid crystal display device 52 are separated. There is a problem that the work process is complicated and the efficiency is lowered because care is required to avoid.
따라서, 본 고안의 목적은 액정 표시 장치용 모듈을 하우징과 베젤에 수납시 액정표시장치의 면적을 줄이기 위해 제1기판을 구부려 하우징의 저면에 밀착시킴에 따른 불량 발생을 감소시킴과 아울러 작업 공정을 단순화하여 작업 능률을 향상시킬 수 있는 액정 표시 장치용 모듈 구조를 제공함에 있다.Accordingly, an object of the present invention is to reduce the occurrence of defects caused by bending the first substrate to adhere to the bottom of the housing to reduce the area of the liquid crystal display when the module for the liquid crystal display device is accommodated in the housing and the bezel. It is to provide a module structure for a liquid crystal display device that can simplify the work efficiency.
[문제점을 해결하기 위한 수단][Means to solve the problem]
상기한 목적을 실현하기 위하여 본 고안은 외부 신호가 인가되는 제1기판에 드라이버 칩을 장착하고 이를 하우징에 형성된 제브라 삽입공을 통해 여기에 삽입된 제브라로 액정표시소자와 연결하고 구부리지 않는 제2기판은 드라이버 칩이 장착된 플렉시블 와이어로 연결 사용하도록 구성함을 특징으로 한다.In order to achieve the above object, the present invention includes a driver chip mounted on a first substrate to which an external signal is applied, and a second substrate connected to the liquid crystal display by a zebra inserted through the zebra insertion hole formed in the housing and not bent. The driver chip is characterized in that it is configured to use the connection to the flexible wire mounted.
물론, 상기한 제1기판은 액정표시소자를 내장한 하우징의 저면에 통상의 나사 등으로 고정된 상태이고 상기한 제브라는 제1기판과 액정표시소자의 매트릭스 전극에서 인출된 리이드 패턴을 정확히 연결시킬 수 있는 형상이다.Of course, the first substrate is fixed to the bottom of the housing in which the liquid crystal display device is built, and the zebra is used to accurately connect the lead pattern drawn from the matrix electrode of the first substrate and the liquid crystal display device. It is a shape that can be.
[작용][Action]
하우징에 제브라 삽입공을 형성하고 여기에 삽입된 제브라로 액정표시소자와 드라이버 칩이 장착된 제1기판을 연결함으로써 접촉 불량이 배제되어 드라이버 칩이 내장된 플렉시블 와이어를 통해 액정표시소자에 외부 신호가 입력될 때 보다 외부신호의 액정표시소자 입력이 신뢰성을 가지게 된다.A zebra insertion hole is formed in the housing, and the zebra inserted therein connects the liquid crystal display device and the first substrate on which the driver chip is mounted, thereby eliminating contact defects, so that an external signal is applied to the liquid crystal display device through the flexible wire having the driver chip. When inputted, the liquid crystal display element input of the external signal is more reliable.
물론, 상기한 액정표시소자는 베젤에 의해 고정됨과 아울러 압착되어 있고 제1기판은 나사 등으로 하우징 저면에 고정되어 있기 때문에 위치 변경으로 인한 제브라와의 접촉 불량이 발생되지 않는다.Of course, since the liquid crystal display is fixed by the bezel and is compressed, and the first substrate is fixed to the bottom of the housing by a screw or the like, there is no poor contact with the zebra due to the position change.

제1도는 본 고안에 따른 액정표시장치를 도시한 평면도로서, 하우징(58)에 액정표시소자(52)가 안착되어 있고 상기한 액정표시소자(52)의 일측에 제2기판(56)이 드라이버 칩(53)이 내장된 플렉시블 와이어(54)로 연결되어 있고 이와 직교 축면 액정표시소자(52)의 아래에 제브라(1)가 밀착되어 있으며 여기에 드라이버 칩(2)이 장착된 제1기판(3)이 접촉됨과 아울러 하우징(58)의 저면에 고정되어 있다.FIG. 1 is a plan view showing a liquid crystal display device according to the present invention, in which a liquid crystal display device 52 is seated on a housing 58, and a second substrate 56 is disposed on one side of the liquid crystal display device 52. The first substrate is connected with a flexible wire 54 having a chip 53 embedded therein, and a zebra 1 is closely attached to the orthogonal axial liquid crystal display device 52 and the driver chip 2 is mounted thereon. 3) is contacted and fixed to the bottom of the housing 58.

Will be connected.
여기서, 상기한 제브라(1)와 제1기판(3)의 연결 상태는 제2도에 도시된 바와 같이 하우징(58) 저면에 드라이버 칩(2)이 장착된 제1기판(3)이 부착되어 있고 하우징(58)의 내측에는 백 라이트(59)가 삽입되어 있으며 그 상부에 액정표시소자(52)가 위치되어 있을 뿐만 아니라 하우징(58)의 제브라 삽입공(4)에 삽입된 제브라(1)에 의해 제1기판(3)과 액정표시소자(52)가 접촉되어 있고 베젤(61)에 의해 고정되어 있다.Here, as shown in FIG. 2, the zebra 1 and the first substrate 3 are connected to each other by attaching the first substrate 3 having the driver chip 2 mounted on the bottom surface of the housing 58.

The first substrate 3 and the liquid crystal display element 52 are in contact with each other, and are fixed by the bezel 61.
물론, 상기한 제브라(1)는 도전성 물질 즉 흑연 등이 고무에 일정 패턴으로 침착 형성된 도전성 고무이다.Of course, the zebra 1 is a conductive rubber in which a conductive material, that is, graphite or the like is deposited on the rubber in a predetermined pattern.
외부신호가 제1기판(3)과 제2기판(56)을 통해 액정표시소자(52)로 입력될 때 제2기판(56)을 통한 신호는 플렉시블 와이어(54)를 통해 입력되고 제1기판(3)으로 인가되는 신호는 제브라(1)를 통해 인가된다.When an external signal is input to the liquid crystal display device 52 through the first substrate 3 and the second substrate 56, the signal through the second substrate 56 is input through the flexible wire 54 and the first substrate. The signal applied to (3) is applied through the zebra (1).
여기서, 제브라(1)가 삽입되는 제브라 삽입공(4)은 제브라(1)가 삽입된 후 유동되지 않도록 제브라(1)의 크기와 동일하게 형성된다.Here, the zebra insertion hole 4 into which the zebra 1 is inserted is formed in the same size as the zebra 1 so that the zebra 1 is not flowed after being inserted.
