Description
본 발명은 타일드 액정표시장치에 관한 것으로, 더욱 상세하게는 패널들을 하나의 연성 회로기판을 이용하여 접합시켜 패널들 사이의 틈을 줄임으로써 화상 품질을 향상시키도록 한 타일드 액정표시장치의 패널 연결 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tiled liquid crystal display device, and more particularly, to a panel of a tiled liquid crystal display device in which the panels are bonded using a single flexible circuit board to improve image quality by reducing gaps between the panels. It is about a connection structure.
일반적으로 알려진 바와 같이, 전자표시장치는 시각정보의 전달수단으로서 중요성을 높임과 동시에 정보화사회가 구현되는 속에서 산업의 규모를 확대하고 있다. 멀티미디어라는 단어로 대표되는 정보의 다양화는 전자표시장치의 필요성을 일층 더 명확하게 하고 있다. 동시에 전자표시장치에 대한 요구도 대화면, 고화질, 뛰어난 시인성 및 경제성이 강해지고 있으며, 특히 휴대용 정보기기에서는 저전압/저소비전력이 필수 조건으로 요구되고 있다.As is generally known, the electronic display device is increasing in importance as a means of transmitting visual information and at the same time expanding the scale of the industry in the realization of an information society. The diversification of information represented by the word multimedia makes the necessity of an electronic display device even more clear. At the same time, the demand for an electronic display device is also becoming large, high-definition, excellent visibility and economical efficiency, especially low voltage / low power consumption is required as a requirement in portable information equipment.
이러한 전자표시장치 중의 하나로서 박형/경량, 저소비전력을 특징으로 응용시장을 확대해온 액정표시장치(liquid crystal display: LCD)는 칼라표시에 의해 그 수요가 급속히 확대되고 있을 뿐 아니라 최근에는 소비자들의 생활 수준이 향상되면서 점점 더 큰 사이즈의 고화질 제품이 요구되어져, 대화면 칼라액정의 양산기술확립을 위한 설비 채용이 본격화되고 있다.As one of such electronic display devices, liquid crystal display (LCD), which has been expanding its application market with thin / light weight and low power consumption, is rapidly expanding its demand by color display, and recently, consumer's life. As the level is improved, larger sized high-definition products are required, and facility adoption for establishing mass production technology of large-screen color liquid crystal is in earnest.
상기 대화면 칼라 액정표시장치는 그 특성상 화면 사이즈를 크게 가져가는데 한계가 따르게 되는데, 지금까지 알려진 최대 패널 사이즈는 22인치이며, 이론적으로는 40인치까지 가능한 것으로 알려져 있다.The large-screen color liquid crystal display device has a limitation in that it takes a large screen size due to its characteristics, and the maximum panel size known so far is 22 inches, and theoretically, it is known that it can be up to 40 inches.
이에 따라, 작은 패널에 광학계를 장착하여 스크린에 큰 화상이 형성되도록 하는 이른바 투사형 TV(projection TV)가 등장하게 되었으며, 최근에는 이보다 한발 더 나아가 한층 더 높은 수준의 화질을 얻을 수 있는 직시형 제품을 모색하기에 이르렀다.As a result, a so-called projection TV, which mounts an optical system on a small panel so that a large image is formed on a screen, has emerged. In recent years, a direct-view product that can obtain a higher level of image quality has been further advanced. I sought.
이러한 발전 추세를 따른다 하더라도 액정표시장치의 실제 화면 사이즈를 크게 가져가는데에는 한계가 있어, 현재는 대화면 표시장치를 만들기 위하여 여러장의 배열된 패널을 접합한 타일드 액정표시장치(tiled LCD)가 실용화되어 왔다.Even if this development trend is followed, there is a limit to bringing the actual screen size of the liquid crystal display large, and now, a tiled liquid crystal display (tiled LCD) in which several array panels are laminated to make a large display is practically used. come.
종래의 타일드 액정표시장치의 경우, 도 1에 도시된 바와 같이, 2개의 연성 회로기판들(11),(13)이 패널들(21),(23)의 사이에 위치하며 패널들(21),(23)에 각각 제어부(도시 안됨)의 신호들을 전달하도록 전기적 연결된다. 즉, 패널들(21),(23)의 측면에 형성된 투광성 전극용 ITO(Indium Tin Oxide) 재질의 패드들(22),(24)은 도시되지 않은 이방성 도전 필름(anisotropic conductive film)에 의해 연성 회로기판들(11),(13)의 패드들(12),(14)에 접합된다.In the conventional tiled liquid crystal display, as shown in FIG. 1, two flexible circuit boards 11 and 13 are positioned between the panels 21 and 23, and the panels 21 are disposed in the panel 21. And 23 are electrically connected to each other to transmit signals of a controller (not shown). That is, the pads 22 and 24 made of indium tin oxide (ITO) material for translucent electrodes formed on the side surfaces of the panels 21 and 23 are soft by an anisotropic conductive film (not shown). The pads 12 and 14 of the circuit boards 11 and 13 are bonded to each other.
그러나, 이와 같이 접합되는 종래의 방식에서는 2개의 패널들 사이에서 독립된 2개의 연성 회로기판들이 개별적으로 부착된다. 이는 2개의 연성 회로기판과 이방성 도전필름의 두께만큼 패널들 사이의 틈을 확대시켜 사용자로 하여금 접합된 패널들 사이의 연결 부분을 쉽게 인식시킨다. 이로 말미암아, 화상의 자연스러운 연결이 이루어지지 못하고 화상의 품질 저하를 가져온다.However, in the conventional manner of such bonding, two independent flexible circuit boards are separately attached between the two panels. This enlarges the gap between the panels by the thickness of the two flexible circuit boards and the anisotropic conductive film so that the user can easily recognize the connection between the bonded panels. By this, the natural connection of the images is not achieved and the quality of the images is degraded.
또한, 종래에는 연성 회로기판이 다층구조로 제작 가능함에 불구하고 패널의 패드 또는 인쇄회로기판의 접속패턴에 실제 접합되는 패드는 연성 회로기판의 한쪽면에만 형성되므로 복잡하고 다양해진 제품에 적용하는데 제한을 받아 왔다.In addition, although the flexible circuit board can be manufactured in a multi-layered structure, the pad that is actually bonded to the pad of the panel or the connection pattern of the printed circuit board is formed only on one side of the flexible circuit board, and thus it is limited to be applied to complicated and diverse products. Have been received.
따라서, 본 발명의 목적은 연성 회로기판의 양쪽면에 패드들 형성하여 패널들을 틈을 줄이면서 접합하도록 한 것이다.Accordingly, it is an object of the present invention to form pads on both sides of a flexible circuit board to bond panels with a small gap.
본 발명의 다른 목적은 다음의 상세한 설명 및 첨부된 도면에 의해 보다 명확해질 것이다.Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

도 2를 참조하면, 연성 회로기판(31)은 패널들(21),(23) 사이에 위치하고, 연성 회로기판(31)의 좌, 우 양쪽면에 각각 형성된 패드들(32),(34)이 이방성 도전 필름(도시 안됨)에 의해 패널들(21),(23)의 패드들(22),(24)에 대응하여 접합된다.Referring to FIG. 2, the flexible circuit board 31 is positioned between the panels 21 and 23, and pads 32 and 34 formed on both left and right sides of the flexible circuit board 31, respectively. The anisotropic conductive film (not shown) is bonded corresponding to the pads 22 and 24 of the panels 21 and 23.
이와 같이 접합되는 본 발명의 방식에서는 패널들(21),(23) 사이에 하나의 연성 회로기판(31)이 부착되므로 종래의 두 개의 연성 회로기판들(11),(13) 중 어느 하나의 연성 회로기판의 생략이 가능하다.In the method of the present invention, the flexible circuit board 31 is attached between the panels 21 and 23, so that any one of the two conventional flexible circuit boards 11 and 13 is attached. It is possible to omit the flexible circuit board.
따라서, 본 발명은 접합된 패널들 사이의 틈을 줄이고 나아가 타일드 액정표시장치의 화상 품질을 향상시킬 수 있다.Therefore, the present invention can reduce the gap between the laminated panels and further improve the image quality of the tiled liquid crystal display.
이상에서 설명한 바와 같이, 본 발명에 따르면 연성 회로기판의 양쪽면에 패드들을 이용하여 하나의 연성 회로기판이 패널들 사이에 접합된다.As described above, according to the present invention, one flexible circuit board is bonded between panels by using pads on both sides of the flexible circuit board.
따라서, 본 발명은 접합된 패널들 사이의 틈을 좁혀 타일드 액정표시장치의 화상 품질을 향상시킬 수 있다.Therefore, the present invention can narrow the gap between the laminated panels to improve the image quality of the tiled liquid crystal display.
