Description

타일드 액정표시장치의 엘씨디 패널{LCD panel of tiled liquid crystal dispaly}LCD panel of tiled liquid crystal dispaly

도 1은 본 발명의 제 1 실시예에 의한 타일드 액정표시장치의 LCD 패널을 도시한 평면도이고,1 is a plan view showing an LCD panel of a tiled liquid crystal display according to a first embodiment of the present invention;

도 2는 본 발명의 제 2 실시예에 의한 타일드 액정표시장치의 LCD 패널을 도시한 평면도이다.2 is a plan view illustrating an LCD panel of a tiled liquid crystal display according to a second exemplary embodiment of the present invention.

본 발명은 타일드 액정표시장치의 엘씨디 패널에 관한 것으로, 더욱 상세하게는 픽셀들의 개구 면적을 증대시키기 위해서 픽셀들 사이에 형성되는 이격공간의 평균적인 폭을 씰 형성 영역의 폭보다 좁게 형성한 타일드 액정표시장치의 엘씨디 패널에 관한 것이다.The present invention relates to an LCD panel of a tiled liquid crystal display device, and more particularly, in order to increase the opening area of pixels, an average width of the separation space formed between the pixels is smaller than that of the seal formation region. The present invention relates to an LCD panel of a yield liquid crystal display device.

일반적으로, CRT의 대체품으로 각광을 받고 있는 액정표시장치는 경량화, 박형화, 저소비전력 등과 같은 장점을 가지고 있어 그 수요가 급속히 확대되고 있으며, 최근에는 소비자들의 생활 수준이 향상되어 액정표시장치의 고화질 및 대화면성이 요구되고 있다.In general, the liquid crystal display device, which has been spotlighted as an alternative to the CRT, has advantages such as light weight, thinness, and low power consumption, and its demand is rapidly expanding. Large surface area is required.

그러나, 액정표시장치의 특성상 화상이 표시되는 화면 사이즈를 크게 하는데 한계가 있고, 지금까지 알려진 최대 액정표시장치의 화면 사이즈는 30인치이며, 이론적으로는 40 인치까지 가능한 것으로 알려져 있다. However, due to the characteristics of the liquid crystal display device, there is a limit to increasing the screen size on which an image is displayed. The screen size of the largest liquid crystal display device so far known is 30 inches, and theoretically, it is known that it is possible to reach 40 inches.

이에 따라, 작은 LCD 패널에 광학계를 장착하여 스크린에 큰 화상이 표시되도록 하는 이른바 투사형 TV(projection TV)가 등장하게 되었으며, 최근에는 대화면 표시소자를 만들기 위하여 여러개의 액정표시장치를 연결하여 대화면을 구현한 타일드 액정표시장치가 실용화되고 있다.Accordingly, a so-called projection TV has been introduced, in which a large image is displayed on a screen by mounting an optical system on a small LCD panel. Recently, a large screen is realized by connecting several liquid crystal display devices to make a large display device. One tiled liquid crystal display device has been put into practical use.

타일드 액정표시장치는 미국 특허공보 제 4,980,775호, 제 5,067,021호, 제 5,068,740호, 제 5,079,636호에 제시된 바와 같이 2개이상의 LCD 모듈을 서로 접합시켜 제작하는 것으로, 서로 접합된 LCD 모듈과 LCD 모듈의 경계부분이 눈으로 식별되지 않아야 한다.The tiled liquid crystal display device is manufactured by bonding two or more LCD modules to each other as shown in US Patent Nos. 4,980,775, 5,067,021, 5,068,740, and 5,079,636. The border should not be visible to the eye.

이와 같이 LCD 모듈과 LCD 모듈의 경계부분이 눈으로 식별되어 화상이 중단되는 현상을 방지하기 위해서 LCD 모듈들 사이의 간격, 즉 서로 인접한 2개의 LCD 패널에서 액정을 밀봉하는 씰(seal)이 형성되는 씰 형성영역의 폭을 합한 만큼의 간격과 LCD 패널 상에 형성된 화소들 사이의 간격을 동일하게 형성한다.As such, the boundary between the LCD module and the LCD module is visually identified to prevent the image from being interrupted. A gap between the LCD modules, that is, a seal that seals the liquid crystal in two adjacent LCD panels is formed. The intervals of the sum of the widths of the seal formation regions and the intervals between the pixels formed on the LCD panel are equally formed.

그러므로, LCD 패널을 구성하는 2개의 기판 중 TFT 기판에서는 픽셀(3개의 화소전극 묶음)과 픽셀 사이에 씰 형성 영역의 2배가되는 공백부분이 존재하고, 칼라필터 기판에서는 픽셀(3개의 화소전극과 대응되는 부분에 형성된 R,G,B)과 픽셀사이에 TFT 기판의 공백부분과 동일한 폭으로 블랙매트릭스가 형성된다. Therefore, among the two substrates constituting the LCD panel, there is a blank portion in the TFT substrate, which is twice as large as the seal formation region, in the TFT substrate, and in the color filter substrate, the pixel (the three pixel electrodes and A black matrix is formed between the pixels R, G, and B formed in the corresponding portion and the same width as the blank portion of the TFT substrate.

이러한, 공백부분과 블랙매트릭스는 앞에서 설명한 바와 같이 LCD 모듈들 사 이의 간격과 픽셀들 사이의 간격을 서로 동일하게 형성하여 LCD 모듈들의 경계부분이 눈으로 식별되는 것을 방지하기 위한 것이다.As described above, the blank portion and the black matrix are to form the same gap between the LCD modules and the gap between the pixels so as to prevent the boundary of the LCD modules from being identified by the eyes.

그러나, 픽셀가 픽셀 사이를 씰 형성 영역 폭의 2배정도 되도록 이격시킬 경우 빛을 통과시키는 각 픽셀의 개구 면적이 그만큼 작아지기 때문에 타일드 액정표시장치의 해상도가 저하되는 문제점이 있었다.However, when the pixels are spaced apart from each other by about twice the width of the seal formation region, the resolution of the tiled liquid crystal display device is lowered because the opening area of each pixel through which light passes is reduced by that much.

따라서, 본 발명의 목적은 상기와 같은 문제점을 감안하여 안출된 것으로써, LCD 패널에 형성된 각 픽셀들의 개구율을 증대시켜 타일드 액정표시장치의 해상도를 향상시키는데 있다.Accordingly, an object of the present invention has been made in view of the above problems, and is to improve the resolution of a tiled liquid crystal display by increasing the aperture ratio of each pixel formed in the LCD panel.

이와 같은 목적을 달성하기 위해서 본 발명은 한 장의 LCD 패널에서 화상이 중단되는 것을 방지하기 위해 픽셀들 사이에 형성되는 이격공간의 평균적인 폭을 상기 LCD 패널의 가장자리에 형성되는 씰 형성 영역의 폭보다 좁게 형성한다.In order to achieve the above object, the present invention provides an average width of the separation space formed between the pixels to prevent the image from being interrupted in one LCD panel, rather than the width of the seal forming region formed at the edge of the LCD panel. To form narrowly.

일예로, 픽셀들 사이에 각각 형성되는 이격공간들의 폭은 서로 동일하게 형성되며, 각 이격공간들의 폭은 실 형성 영역의 폭보다 작다. For example, the widths of the separation spaces formed between the pixels are formed to be the same, and the widths of the separation spaces are smaller than the width of the yarn formation region.

다른 예로, 픽셀들 사이의 형성되는 각 이격공간들의 폭을 일정주기마다 반복적으로 다르게 형성되는데, LCD 패널에 형성된 복수개의 픽셀들에서 LCD 패널의 길이방향 및 폭방향으로 각각 2개씩의 픽셀들을 건너 뛰어 이격공간을 씰 형성 영역 폭의 2개가 되도록 형성하고, 씰 형성 영역 폭의 2배가 되도록 형성된 이격공간들 사이에 형성된 픽셀들 사이의 이격공간은 씰 형성 영역의 폭보다 좁게 형성한 다.As another example, the widths of the spaces formed between the pixels are repeatedly different at regular intervals, and two pixels in the length direction and the width direction of the LCD panel are skipped from the plurality of pixels formed in the LCD panel. The separation space is formed to be two of the width of the seal formation region, and the separation space between the pixels formed between the separation spaces formed to be twice the width of the seal formation region is smaller than the width of the seal formation region.

이하, 본 발명에 의한 타일드 액정표시장치의 LCD 패널을 첨부된 도면 도 1 및 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, an LCD panel of a tiled liquid crystal display according to the present invention will be described with reference to FIGS. 1 and 2.

타일드 액정표시장치(100)에서 화상을 표시하는 LCD 패널들(110)은 TFT 기판(도시 안됨)과, TFT 기판에 마주보도록 부착되고 TFT 기판의 크기가 동일한 칼라필터 기판(도시 안됨)과, TFT 기판과 칼라필터 기판 사이에 주입되며 전기 광학적 성질에 의해 구동되는 액정(도시 안됨)으로 구성된다.LCD panels 110 for displaying an image in the tiled liquid crystal display device 100 include a TFT substrate (not shown), a color filter substrate (not shown) attached to face the TFT substrate and having the same size as the TFT substrate, It is composed of a liquid crystal (not shown) which is injected between the TFT substrate and the color filter substrate and driven by electro-optic properties.

여기서, TFT 기판과 칼라필터 기판의 가장자리를 따라 액정을 밀봉하기 위해 씰을 형성하는 씰 형성영역(ℓ';도 1 및 도 2 참조)이 존재한다.Here, there is a seal formation region L '(see Figs. 1 and 2) which forms a seal to seal the liquid crystal along the edges of the TFT substrate and the color filter substrate.

TFT 기판에서 씰 형성 영역(ℓ')의 내측에는 복수개의 게이트선들(120)이 TFT 기판의 폭방향으로 일렬로 배열되고, 게이트선들(120)과 교차되도록 TFT 기판의 세로방향을 따라 복수개의 데이터선들(125)이 일렬로 형성된다. 또한, 게이트선들(120,160)과 데이터선들(125)의 교차점에 박막트랜지스터 소자들(도시 안됨)이 형성되고, 교차 영역 내에는 화소전극들(도시 안됨)이 형성된다.In the TFT substrate, a plurality of gate lines 120 are arranged in a line in the width direction of the TFT substrate inside the seal formation region ℓ 'and a plurality of data along the longitudinal direction of the TFT substrate so as to cross the gate lines 120. Lines 125 are formed in a line. In addition, thin film transistor elements (not shown) are formed at intersections of the gate lines 120 and 160 and the data lines 125, and pixel electrodes (not shown) are formed in the intersection area.

타일드 액정표시장치(100)에 사용되는 LCD 패널들(110)의 경우 LCD 패널들(110)과 사이의 경계부분에서 화상이 중단되어 보이는 현상을 방지하기 위해서 TFT 기판의 경우 픽셀들(130,133,135) 사이의 간격, 즉 이격공간(140)을 씰 형성 영역(ℓ')의 2배가되도록 뛰운다. In the case of LCD panels 110 used in the tiled liquid crystal display device 100, pixels 130, 133, and 135 may be used in the case of a TFT substrate in order to prevent the image from being displayed at the boundary between the LCD panels 110. The interval between them, that is, the space 140, jumps to be twice as large as the seal formation region l '.

한편, 칼라필터 기판에서 씰 형성 영역(ℓ')의 내측에는 백라이트 어셈블리에서 발산된 빛의 투과량에 따라 각종 색을 나타내는 적색, 녹색, 청색 칼라필터 와, 블랙매트릭스가 형성된다.Meanwhile, red, green, and blue color filters and black matrices representing various colors are formed inside the seal formation region l 'of the color filter substrate according to the amount of light emitted from the backlight assembly.

여기서, 칼라필터는 화소전극과 대응되는 부분에 형성되고, 블랙매트릭스는 게이트선들(120) 및 데이터선들(125)과 대응되는 부분과 픽셀들(130,133,135) 사이의 이격공간(140)과 대응되는 부분에 형성된다.Here, the color filter is formed at a portion corresponding to the pixel electrode, and the black matrix is a portion corresponding to the gate lines 120 and the data lines 125 and a portion corresponding to the separation space 140 between the pixels 130, 133, and 135. Is formed.

픽셀(130,133,135)이란 3개의 화소전극과, 각각의 화소전극에 대응하는 한 개의 적색, 녹색, 청색의 묶음을 의미하는 것으로, 다시 말해 한 개의 적색, 한 개의 녹색, 한 개의 청색과 이들 색에 대응되는 각각의 화소전극들의 묶음을 한 개의 픽셀이라 정의한다.Pixels 130, 133, and 135 refer to a combination of three pixel electrodes and one red, green, and blue corresponding to each pixel electrode, that is, one red, one green, one blue, and corresponding colors. Each pixel electrode is defined as one pixel.

이와 같이 구성된 LCD 패널들(110)의 해상도를 향상시키기 위해서 본 발명은 LCD 패널들(110)의 경계부분이 육안으로 식별되지 않는 범위에서 픽셀들(130,133,135) 사이의 간격을 줄여 각 픽셀들(130,133,135)의 개구면적(개구율)을 증대시킨다.In order to improve the resolution of the LCD panels 110 configured as described above, the present invention reduces the distance between the pixels 130, 133, and 135 in a range where the boundary of the LCD panels 110 is not visually identified. Increase the opening area (opening ratio) of

본 발명의 제 1 실시예에 따르면, 픽셀들(130,133,135)의 개구면적을 증대시키기 위해서 도 1에 도시된 바와 같이 LCD 패널(110)의 길이방향 쪽으로 형성되는 픽셀들(133,135)간의 이격공간(143)의 폭을 씰 형성영역(ℓ')의 폭보다 1/3정도 좁혀 형성하고, LCD 패널(110)의 폭방향 쪽으로 형성되는 픽셀들(130,133) 사이에 형성되는 이격공간(145)의 폭은 실 형성 영역(ℓ')의 폭과 동일하게 형성한다.According to the first embodiment of the present invention, the separation space 143 between the pixels 133, 135 formed in the longitudinal direction of the LCD panel 110, as shown in Figure 1 to increase the opening area of the pixels (130, 133, 135) ) Is formed by narrowing the width of the seal forming region (l ') by about 1/3, and the width of the separation space 145 formed between the pixels 130 and 133 formed toward the LCD panel 110 in the width direction. It is formed equal to the width of the yarn forming region l '.

결과적으로, 픽셀(130,135)과 픽셀(133) 사이에 형성된 이격공간(143,145)의 폭은 서로 인접한 2개의 LCD 패널(110)에서 씰 형성 영역(ℓ')의 폭을 합한 길이(ℓ)보다 작게 형성됨으로써, 이격공간(140)의 폭이 줄어든 만큼 각 픽셀들(130,133,135)의 개구 면적은 커진다.As a result, the widths of the separation spaces 143 and 145 formed between the pixels 130 and 135 and the pixel 133 are smaller than the sum of the widths l of the seal forming regions l 'in the two LCD panels 110 adjacent to each other. As a result, the opening area of each pixel 130, 133, 135 is increased as the width of the separation space 140 is reduced.

즉, LCD 패널(110)의 길이방향을 따라 형성되는 이격공간(143) 폭은 2개의 LCD 패널들(110)에서 씰 형성 영역(ℓ')의 폭을 합한 길이(ℓ)의 1/3정도이고, LCD 패널(110)의 폭방향으로 길게 형성되는 이격공간(145)의 폭은 2개의 LCD 패널들(110)에서 씰 형성 영역(ℓ')의 폭을 합한 길이(ℓ)의 1/2정도 이다.That is, the width of the separation space 143 formed along the longitudinal direction of the LCD panel 110 is about 1/3 of the length ℓ, which is the sum of the widths of the seal forming regions ℓ 'in the two LCD panels 110. The width of the separation space 145 that is formed to be long in the width direction of the LCD panel 110 is 1/2 of the length (l), which is the sum of the widths of the seal forming region (l ') in the two LCD panels (110). Is enough.

제 1 실시예서는 LCD 패널(110)을 복수개 접합시켰을 경우 LCD 패널들(110)의 경계면에서만 픽셀과 픽셀들 사이의 길이(ℓ)폭이 넓기 때문에 LCD 패널들(110)의 경계부분이 눈으로 구분될 가능성이 있으므로, 본 발명의 제 2 실시예에서는 이러한 현상을 제거하기 위해 픽셀들(170,173,175) 사이의 이격공간(180) 폭을 일정주기마다 반복적으로 다르게 형성한다.In the first embodiment, when a plurality of LCD panels 110 are bonded together, the boundary portions of the LCD panels 110 may not be visible because the width (l) between the pixels is wide only at the boundary surfaces of the LCD panels 110. In the second embodiment of the present invention, the width of the space 180 between the pixels 170, 173, and 175 is repeatedly formed differently at regular intervals in order to eliminate such a phenomenon.

이를 좀더 상세히 언급하면, 도 2에 도시된 바와 같이 LCD 패널(110)의 길이 방향 및 폭방향으로 형성되는 픽셀들에서 2개씩의 픽셀(170, 173)(173,175)을 건너 뛰어 픽셀(170)(175)과 픽셀(170')(175') 사이의 이격공간(183)(185) 폭을 씰 형성영역 폭(ℓ')의 2배가 되도록 형성하고, 씰 형성 영역 폭(ℓ')의 2배가 되는 이격공간들(183)(185) 사이에 형성되는 픽셀들(170, 173)(173,175) 사이의 이격공간(183, 185) 폭은 씰 형성 영역(ℓ')의 폭보다 좁게 형성한다. In more detail, as illustrated in FIG. 2, the pixels 170 are skipped by two pixels 170 and 173 and 173 and 175 in pixels formed in the length direction and the width direction of the LCD panel 110. The width of the spaced spaces 183 and 185 between the 175 and the pixels 170 'and 175' is formed to be twice the width of the seal formation region l 'and twice the width of the seal formation region L'. The widths of the separation spaces 183 and 185 between the pixels 170 and 173 and 173 and 175 formed between the spaced spaces 183 and 185 are smaller than the width of the seal formation region l '.

즉, LCD 패널(110)의 길이방향 및 폭방향으로 첫 번째 형성된 픽셀(173)과 두 번째 형성된 픽셀들(170,175) 사이의 이격공간(185)은 씰 형성 영역(ℓ')의 폭보다 좁게 형성하고, LCD 패널(110)의 길이방향 및 폭방향으로 두 번째 형성된 픽셀(170,175)과 세 번째 형성된 픽셀들(170',175') 사이의 이격공간(183)은 씰 형성 영역(ℓ')의 폭의 2배가 되도록 형성한다.That is, the separation space 185 between the first formed pixel 173 and the second formed pixels 170 and 175 in the longitudinal direction and the width direction of the LCD panel 110 is formed to be narrower than the width of the seal formation region l '. In addition, the separation space 183 between the second and second pixels 170 and 175 and the third and second pixels 170 and 175 'in the longitudinal and width directions of the LCD panel 110 is formed in the seal formation region l'. It is formed to be twice the width.

앞에서 설명한 바와 같이, 픽셀들 사이의 이격공간을 평균적으로 폭을 씰 형성 영역의 폭보다 좁게 형성할 경우 개구 면적이 증대되어 백라이트에서 발산된 빛이 많이 투과되므로 해상도는 그만큼 향상된다.As described above, in the case where the width between the pixels is formed to be smaller than the width of the seal formation region on the average, the opening area is increased so that much light emitted from the backlight is transmitted, so that the resolution is improved.

이상에서 설명한 바와 같이 본 발명은 픽셀들 사이에 형성된 이격공간의 평균적인 폭을 씰 형성 영역의 폭보다 좁게 형성하여 각 픽셀들의 개구면적을 증대시킴으로써, 타일드 액정표시장치의 해상도를 향상시킬 수 있는 효과가 있다.As described above, the present invention increases the opening area of each pixel by forming an average width of the separation space formed between the pixels smaller than the width of the seal formation region, thereby improving the resolution of the tiled liquid crystal display device. It works.
