도 3은 본 발명의 기술에 따른 다른 실시예에 의한 타일드 액정표시장치를 나타낸 단면도.3 is a cross-sectional view showing a tiled liquid crystal display device according to another embodiment according to the technology of the present invention.

본 발명은 타일드 액정표시장치에 관한 것으로, 더욱 상세하게는 에지전극드들의 형성에 따른 쇼트 발생을 방지할 수 있도록 한 타일드 액정표시장치에 관한 것이다.The present invention relates to a tiled liquid crystal display device, and more particularly, to a tiled liquid crystal display device capable of preventing short generation caused by formation of edge electrodes.

일반적으로 전자표시장치는 시각정보의 전달수단으로써 중요성을 높임과 동시에 정보화 사회가 구현되는 속에서 산업의 규모를 확대하고 있다.In general, the electronic display device is increasing the size of the industry in the realization of the information society while increasing the importance as a means of transmitting visual information.

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, 저소비전력을 필수 조건으로 요구되고 있다.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 in portable information equipment.

이러한 전자표시장치 중의 하나로써 박형화, 경량화, 저소비전력을 특징으로 응용 시장을 확대해온 액정표시장치(liquid crystal display ; LCD)는 칼라표시에 의해 그 수요가 급속히 확대되고 있을 뿐만 아니라 최근에는 소비자들의 생활수준이 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 displays (LCDs), which have expanded the application market by thinning, lightening, and low power consumption, are rapidly expanding their demand by color display, and in recent years, consumers' lives. 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.

상기에서 언급한 대화면 칼라 액정표시장치는 그 특성상 화면 사이즈를 크게 가져가는데 한계가 따르게 되는데, 지금까지 알려진 최대 패널 사이즈는 22인치이며, 이론적으로 40 인치까지 가능한 것으로 알려져 있다.The above-mentioned large-screen color liquid crystal display device has a limitation in that the screen size is large due to its characteristics. 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 되었다.As a result, a so-called projection TV has been introduced, in which an optical system is mounted on a small panel to form a large image on a screen.

이러한 발전 추세를 따른다 하더라도 액정표시장치의 실제 화면 사이즈를 크게 가져가는데에는 한계가 있어, 현재는 대화면 표시장치를 만들기 위하여 여러장의 배열된 엘시디 패널을 접합한 타일드 액정표시장치(tiled LCD)가 실용화되고 있다.Even with this development trend, 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 a plurality of arranged LCD panels are bonded to make a large display is put to practical use. It is becoming.

이러한 타일드 액정표시장치를 구성하기 위해서 엘시디 패널의 측면으로 게이트/데이터 라인들의 측단들이 표출되고, 신호전달을 위한 히트실(heat seal)과의 안정적인 본딩을 위해 상기 측단들 각각에 에지전극패드들이 각각 증착 형성되어 전기적으로 연결된다.In order to form the tiled liquid crystal display, side ends of the gate / data lines are exposed to the side of the LCD panel, and edge electrode pads are disposed at each of the side ends for stable bonding with a heat seal for signal transmission. Each is deposited and electrically connected.

그러나, 에지전극패드를 형성할 경우, 공정불량으로 인해 에지전극패드간에 쇼트가 발생되고, 상부기판과 하부기판간에 쇼트가 발생되는 문제점이 있다.However, when the edge electrode pad is formed, a short occurs between the edge electrode pads due to a process defect, and a short occurs between the upper substrate and the lower substrate.

또한, 에지전극패드 형성으로 인해 데이터 라인을 증가시키는데 한계가 발생하는 문제점이 있다.In addition, there is a problem that a limit occurs in increasing the data line due to the formation of the edge electrode pad.

또한, 엘시디 패널과 엘시디 패널 사이의 블랙매트릭스의 폭과 엘시디 패널의 액티브 영역내의 블랙매트릭스의 폭을 동일하게 형성함으로써, 픽셀의 사이즈가 커질수 밖에 없어 화면의 해상도가 저하되는 문제점이 있다.In addition, by forming the same width of the black matrix between the LCD panel and the LCD panel and the width of the black matrix in the active area of the LCD panel, the size of the pixel may be increased and the resolution of the screen may be reduced.

따라서, 본 발명의 목적은 에지전극패드를 형성하지 않는데 있다.Therefore, an object of the present invention is not to form an edge electrode pad.

본 발명의 다른 목적은 게이트/데이터 라인들을 증가시키는데 있다.Another object of the invention is to increase the gate / data lines.

본 발명의 또 다른 목적은 타일드 액정표시장치의 해상도를 향상시키는데 있다.Another object of the present invention is to improve the resolution of a tiled liquid crystal display.

본 발명의 또 다른 목적은 다음의 상세한 설명 및 첨부된 도면으로부터 보다 명확해질 것이다.Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

이와 같은 목적을 달성하기 위해 본 발명은 엘시디 패널의 하부기판의 소정 측면을 상부기판의 대향되는 측면보다 소정 길이 돌출시키고, 돌출된 하부기판의 표면에 형성된 게이트/데이터 라인들의 측단부들과 히트실의 본딩패드들을 각각 본딩하여 전기적으로 연결할 수 있도록 한다.In order to achieve the above object, the present invention protrudes a predetermined side surface of the lower substrate of the LCD panel by a predetermined length from the opposite side surface of the upper substrate, and the heat seals and side ends of the gate / data lines formed on the surface of the protruding lower substrate. Bonding pads are bonded to each other so that they can be electrically connected.

이때, 외부환경으로부터 보호하기 위해 히트 실의 본딩패드들과 게이트/데이터 라인들의 측단부들의 본딩부를 커버하는 보호부재가 하부기판의 돌출영역에 설 치될 수 있으며, 이때, 보호부재는 게이트/데이터 라인들의 측단부들을 일체로 커버하는 샤시로 이루어질 수 있다.In this case, a protection member covering the bonding pads of the heat seal and the bonding portions of the side ends of the gate / data lines may be installed in the protruding region of the lower substrate to protect the external environment. In this case, the protection member may be a gate / data line. It may be made of a chassis that integrally covers the side ends of the.

이러한 보호부재는 광 반사를 최소화하기 위해 저반사체로 이루어지거나, 무정전 플라스틱 재질로 이루어질 수 있다.The protection member may be made of a low reflector or an uninterruptible plastic material to minimize light reflection.

한편, 접착부재의 두께는 적어도 400㎛ ~ 600㎛가 바람직하다.On the other hand, the thickness of the adhesive member is preferably at least 400 μm to 600 μm.

엘시디 패널들간의 경계 영역은 엘시디 패널들간의 상부기판과 하부기판이 오버랩될 수 있다.The boundary area between the LCD panels may overlap the upper substrate and the lower substrate between the LCD panels.

이하 첨부된 도면을 참조하여 본 발명의 기술에 따른 실시예에 의한 타일드 액정표시장치를 보다 상세하게 설명하면 다음과 같다.Hereinafter, a tiled liquid crystal display according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1 또는 도 2를 참조하면, 타일드 액정표시장치는 대응되는 측면끼리 밀착되어 소정의 매트릭스 배열 구조, 예를 들어, 2×2 매트릭스 구조로 이루어지는 직사각형상의 엘시디 패널들(10), 이러한 엘시디 패널들(10)의 저면에 밀착 설치되어 엘시디 패널(10) 방향으로 광을 발생시키는 백라이트 어셈블리(12), 백라이트 어셈블리(12)의 저면에 위치하며, 엘시디 패널들(10)과 전기적으로 연결되어 히트 실(14)을 통해 소정의 구동신호를 엘시디 패널들(10)로 인가하는 구동회로부(16)를 포함하여 구성된다. Referring to FIG. 1 or 2, the tiled liquid crystal display device has rectangular LCD panels 10 formed in a predetermined matrix array structure, for example, a 2 × 2 matrix structure, with corresponding side surfaces in close contact with each other. The backlight assembly 12 is installed in close contact with the bottom of the field 10 to generate light toward the LCD panel 10, and is located at the bottom of the backlight assembly 12. The backlight assembly 12 is electrically connected to the LCD panels 10 and is heated. And a driving circuit unit 16 for applying a predetermined driving signal to the LCD panels 10 through the seal 14.

본 실시예에서는 특정한 2×2 매트릭스 구조로 이루어진 타일드 액정표시장치에 대하여 설명하지만, 이외에도 타일드 액정표시장치는 2×1, 4×4 배열 구조 등으로 이루어지는 엘시디 패널들(10)을 포함할 수 있다.In the present embodiment, a tiled liquid crystal display device having a specific 2x2 matrix structure will be described. In addition, the tiled liquid crystal display device may include LCD panels 10 having a 2x1 or 4x4 array structure. Can be.

이때, 타일드 액정표시장치에 사용되는 엘시디 패널(10)은 직사각형상의 TFT 기판인 하부기판(18)과 이에 대응되는 C/F 기판인 상부기판(20)이 접착부재인 실런트(22)에 의해 상호 대응되어 부착되며, 상부기판(20)과 하부기판(18) 사이에 액정(도시되지 않음)이 개재되어 실런트(22)에 의해 밀봉되어 이루어진다.In this case, the LCD panel 10 used in the tiled liquid crystal display device includes a lower substrate 18, which is a rectangular TFT substrate, and a sealant 22, which is an adhesive member, of the upper substrate 20, which is a C / F substrate. The liquid crystals (not shown) are interposed between the upper substrate 20 and the lower substrate 18 and sealed by the sealant 22.

여기서, 본 발명에 따르면, 히트 실(14)의 본딩패드와 안정적인 본딩을 위해 하부기판(18)의 소정 측면이 상부기판(20)의 대향되는 측면보다 소정 길이 돌출되며, 돌출된 하부기판(18)의 표면에 형성된 게이트/데이터 라인들의 측단부들(24)은 히트 실(14)의 본딩패드들과 각각 본딩되어 전기적으로 연결된다.According to the present invention, a predetermined side surface of the lower substrate 18 protrudes a predetermined length from an opposite side surface of the upper substrate 20 for stable bonding with the bonding pad of the heat seal 14, and the protruding lower substrate 18. The side ends 24 of the gate / data lines formed on the surface of the Ns are bonded and electrically connected to the bonding pads of the heat seal 14, respectively.

이렇게 게이트/데이터 라인들의 측단부들(24)과 히트 실(14)의 본딩패드들이 직접 밀착 본딩됨으로써, 엘시디 패널(10)의 측면에 증착 형성되는 에지전극패드들로 인한 공정상의 불량들을 해결된다.As such, the side end portions 24 of the gate / data lines and the bonding pads of the heat seal 14 are directly bonded to each other, thereby solving process defects due to the edge electrode pads deposited on the side of the LCD panel 10. .

즉, 종래에 엘시디 패널의 측면에 표출된 게이트/데이터 라인들의 측단들에 각각 대응하여 에지전극패드들이 증착 형성될 경우, 게이트/데이터 라인들의 측단들에 대한 에지전극패드들의 증착 미스로 인해 게이트/데이터 라인들의 측단들간에 쇼트가 발생되거나, 에지전극패드 증착 공정시 상부기판의 공통전극과 전기적으로 연결됨으로써 상부/하부기판간의 쇼트로 제품의 신뢰성이 저하되었으며, 에지전극패드 증착 공정을 별도로 진행함으로써 제품의 생산율이 저하되었다.That is, when the edge electrode pads are formed to correspond to the side ends of the gate / data lines, which are conventionally displayed on the side of the LCD panel, the gate / gate due to the deposition miss of the edge electrode pads to the side ends of the gate / data lines. Short circuit occurs between the side ends of the data lines, or electrically connected to the common electrode of the upper substrate during the edge electrode pad deposition process, resulting in a short circuit between the upper and lower substrates, thereby lowering the reliability of the product. The production rate of the product was lowered.

하지만, 본 발명에서는 에지전극패드 증착 공정을 진행하지 않고 게이트/데이터 라인들의 측단부들(24)과 히트 실(14)의 본딩패드들과 각각 대응하여 본딩함으로써, 상기에서 언급한 에지전극패드 증착으로 인해 발생되는 신뢰성 및 생산율 저하를 방지할 수 있다.However, in the present invention, the edge electrode pad deposition described above is bonded by bonding the side end portions 24 of the gate / data lines and the bonding pads of the heat seal 14 without performing the edge electrode pad deposition process. It is possible to prevent the decrease in reliability and production rate caused by.

또한, 에지전극패드를 증착하지 않음으로써, 심리스(sealess) 구현에 따른 픽셀 크기의 한계를 극복할 수 있다.In addition, by not depositing the edge electrode pad, the pixel size limitation due to the seamless implementation may be overcome.

즉, 종래에는 새도우 마스크를 통해 에지전극패드를 증착할 경우, 새도우 마스크의 한계로 인해 게이트/데이터 라인들을 형성하는데 일정 한계가 발생됨으로써 제품의 해상도를 향상시키는데 제약이 따랐지만, 본 발명에서는 에지전극패드들을 형성하지 않기 때문에 게이트/데이터 라인들의 수를 증가시킬 수 있어 제품의 해상도를 향상시킬 수 있다.That is, in the related art, when the edge electrode pad is deposited through the shadow mask, a certain limit is generated in forming gate / data lines due to the limitation of the shadow mask, which is a limitation in improving the resolution of the product. Since no pads are formed, the number of gate / data lines can be increased to improve product resolution.

특히, 종래에는 심리스 구현을 위해 엘시디 패널들 사이의 블랙매트릭스의 폭과 엘시디 패널들의 액티브 영역내의 블랙매트릭스의 폭이 동일하였지만, 본 발명에서와 같이, 에지전극패드들을 형성하지 않고 게이트/데이터 라인들의 수를 증가시킴과 동시에 엘시디 패널들 사이의 경계선에 위치하는 블랙매트릭스의 폭보다 엘시디 패널들의 액티브 영역내의 블랙매트릭스의 폭을 좁게 가져감으로써, 제품의 해상도를 높일 수 있다.In particular, although the width of the black matrix between the LCD panels and the width of the black matrix in the active area of the LCD panels is the same in the related art for a seamless implementation, as in the present invention, the gate / data lines are not formed without forming edge electrode pads. It is possible to increase the resolution of the product by increasing the number and making the width of the black matrix in the active area of the LCD panels narrower than the width of the black matrix located at the boundary between the LCD panels.

상기 경계선에 위치하는 블랙매트릭스의 폭보다 상기 액티브 영역내의 블랙매트릭스의 폭을 좁게 형성함에도 심리스를 구현하는데 악영향을 입히지 않는다. Even if the width of the black matrix in the active region is narrower than the width of the black matrix positioned at the boundary line, it does not adversely affect the implementation of the seamless.

이는 완제품을 구동하여 완제품으로부터 일정거리 이격된 상태에서 완제품에 디스플레이되는 데이터를 볼 경우, 엘시디 패널들간의 경계부분으로부터의 심리스 구현이 이루어짐으로써 가능하다.This can be achieved by seamlessly implementing the boundary between LCD panels when viewing the data displayed on the finished product while driving the finished product at a certain distance from the finished product.

한편, 게이트/데이터 라인들의 측단부들(24)과 히트 실(14)의 본딩패드들이 본딩되는 본딩영역을 외부환경 및 정전기로부터 보호할 수 있도록 게이트/데이터 라인들의 측단부들(24)과 히트 실(14)의 본딩패드들이 본딩되는 하부기판(18)의 돌출영역을 보호부재(26)가 커버하여 설치된다.On the other hand, the side end portions 24 of the gate / data lines and the bonding pads of the heat seal 14 are bonded to the side ends 24 of the gate / data lines so as to protect the bonding area to be bonded from the external environment and static electricity. The protection member 26 covers the protrusion area of the lower substrate 18 to which the bonding pads of the seal 14 are bonded.

이때, 보호부재(26)는 게이트/데이터 라인들의 측단부들(24)을 일체로 커버하는 샤시로, 광 반사를 최소화하기 위해 저반사체로 이루어지며, 정전기 보호를 위해 보호부재(26)는 무정전 플라스틱 재료로 이루어진다.In this case, the protection member 26 is a chassis that integrally covers the side ends 24 of the gate / data lines. The protection member 26 is formed of a low reflector to minimize light reflection, and the protection member 26 is an uninterruptible power source for electrostatic protection. It is made of plastic material.

샤시는 하부기판(18)의 돌출영역으로부터 백라이트 어셈블리(12)의 저면에 밀착된 회로구동부(16)의 저면까지 커버한다. The chassis covers the protruding region of the lower substrate 18 from the bottom of the circuit driver 16 in close contact with the bottom of the backlight assembly 12.
