Description
본 발명은 타일링 기술을 이용하여 LCD판, 일렉트로 루미네센스판등과 같은 복수개의 평판형 표시패널들을 프레임에 접합하여 대면적의 평판형 표시장치를 형성하는 것에 관한 것이다.The present invention relates to joining a plurality of flat panel display panels such as an LCD plate, an electroluminescent plate, etc. to a frame using a tiling technique to form a large area flat panel display device.
평판형 표시장치는 음극선관을 이용한 표시장치보다 무게와 크기를 줄일 수 있는 장점으로 인하여 많은 연구 개발이 이루어져 왔고, 이러한 결과액정표시장치(LCD), 전계방출 표시장치(Field Emission Display: FED), 플라즈마 디스플레이 패널(Plasma Display Panel: PDP), 일렉트로루미네센스(Electroluminescence: EL)등이 개발, 실용화되고 있다. 이 중 PDP는 대형화 화면 구성이 가능하지만 발광효율과 휘도가 낮아 소비전력이 크다는 문제점이 있고, 다른 평판형 표시장치는 대형화된 화면을 구성하기가 곤란하다는 문제점을 갖고 있다. 이와 같이 대형 화면을 구성하기 곤란한 평판형 표시장치에 대한 해결방법의 하나로 개발된 기술이 타일링 기술로서 이는 여러 개의 평판형 표시장치를 기초 프레임에 접합시키는 방법이다.The flat panel display has been researched and developed due to the advantages of reducing the weight and size of the display using a cathode ray tube. As a result, a liquid crystal display (LCD), a field emission display (FED), Plasma Display Panels (PDPs), Electroluminescence (EL), and the like have been developed and put into practical use. Among them, the PDP can be configured with a large screen, but has a problem in that power consumption is low due to low luminous efficiency and luminance, and other flat panel display devices have a problem in that it is difficult to construct a large screen. A technology developed as a solution to the flat panel display device, which is difficult to form a large screen, is a tiling technique, which is a method of bonding a plurality of flat panel display devices to a base frame.
도 1은 종래의 타일링 기술을 이용한 대면적 평판형 표시장치를 설명하기 위한 구성도이다.1 is a block diagram illustrating a large area flat panel display using a conventional tiling technique.
도 1에 도시된 것은 4개의 평판형 표시 패널(1a), (1b), (1c), (1d)들이 프레임(2)에 접합되는 것을 도시한다. 표시패널들은 예를들어 TFT-LCD 패널일 수 있으며, 각각의 패널들은 백라이트 어셈블리, 액정판, 액정층, 편광부재들이 부착되어져 하나의 단위체를 형성한다. 프레임(2)은 외벽을 형성하는 외벽 프레임(2a)과 패널과 패널사이에 개재되는 격벽 프레임(2b)과 밑판(2c)으로 이루어진다. 패널들은 격벽 프레임(2b)과 외벽 프레임(2a)에 의하여 구획된 공간에 안착되어 접합되어지게 된다.FIG. 1 shows that four flat panel display panels 1a, 1b, 1c, and 1d are bonded to the frame 2. The display panels may be, for example, TFT-LCD panels, and each panel is attached to the backlight assembly, the liquid crystal plate, the liquid crystal layer, and the polarizing members to form one unit. The frame 2 is composed of an outer wall frame 2a forming an outer wall, a partition frame 2b and a base plate 2c interposed between the panel and the panel. The panels are seated and joined to the space partitioned by the partition wall frame 2b and the outer wall frame 2a.
이러한 타일링 기술을 이용한 대형화면 구성방법은 격벽 프레임에서 화상이 형성되지 않게 되므로 화면형성시 경계선으로 표시되는 소위 시임(seam) 현상이 발생하게 되어 전체적으로 통일된 화상을 형성하지 못하는 문제점을 앉고 있다.In the large screen configuration method using the tiling technique, since an image is not formed in the partition wall frame, a so-called seam phenomenon, which is displayed as a boundary line when the screen is formed, occurs, which causes a problem of not forming a uniform image as a whole.
따라서, 본 발명은 이와 같은 문제점들을 해결하기 위한 것으로서, 본 발명의 목적은 타일링 기술을 이용한 대면적의 평판형 표시장치의 시임리스(seamless) 현상을 제거하기 위한 평판형 표시장치를 제공하기 위한 것이다.Accordingly, an object of the present invention is to provide a flat panel display device for removing a seamless phenomenon of a large flat panel display device using a tiling technique. .

도 2는 본 발명의 일실시예를 설명하기 위한 구성도이다. 도 3은 본 발명의 일실시예를 설명하기 위한 단면도이다.2 is a block diagram for explaining an embodiment of the present invention. 3 is a cross-sectional view for explaining an embodiment of the present invention.
도 2에 도시된 실시예는 4개의 표시패널, 바람직하기로는 TFT-LCD패널들(1a), (1b), (1c), (1d)이 프레임(4)에 고정설치되며, TFT - LCD 패널들의 상층부에는 4개의 광 가이드판(10a), (10b), (10c), (10d)이 고정설치된다.In the embodiment shown in Fig. 2, four display panels, preferably TFT-LCD panels 1a, 1b, 1c, and 1d are fixed to the frame 4, and a TFT-LCD panel Four light guide plates 10a, 10b, 10c, and 10d are fixed to the upper layer of the field.
이때, 프레임(4)은 프레임의 밑판(4c)과, 밑판(4C)의 외주연을 따라서 형성되는 외벽 프레임(4c)과, 외벽 프레임(4c)에 의하여 형성되는 영역을 균등 분할하기 위하여 마주 보는 외벽 플레임들간에 설치되는 격벽 프레임들(4b)로 이루어진다.At this time, the frame 4 faces the bottom plate 4c of the frame, the outer wall frame 4c formed along the outer periphery of the bottom plate 4C, and the area formed by the outer wall frame 4c to equally divide. It consists of partition frames 4b provided between outer wall frames.
또한, 외벽 프레임(4c)의 내측부는 일정 높이 까지 형성되는 수직면(42)과 수직면에 상향 연장되는 경사면으로 이루어진다. 경사면은 외벽 프레임(4c)의 두께가 상부로 올라갈수록 작도록 경사지게 형성되고, 수직면(42)은 표시패널(1b), (1c)의 측부와 대접되게되고, 경사면(41)은 광 가이드판(10b), (10c)의 외주연 측부에 형성되는 경사면과 대접되게 된다.In addition, the inner portion of the outer wall frame 4c is composed of a vertical surface 42 formed to a predetermined height and an inclined surface extending upwardly to the vertical surface. The inclined surface is formed to be inclined so that the thickness of the outer wall frame 4c increases upward, the vertical surface 42 is to be in contact with the sides of the display panels 1b and 1c, and the inclined surface 41 is a light guide plate ( 10b) and the inclined surface formed in the outer peripheral side part of (10c).
또한, 격벽 프레임(4b)의 양 측부에는 일정높이까지 수직면(44)이 형성되고, 수직면(44)에 상향 연장되는 경사면(43)이 형성된다. 이때, 경사면(43)은 상부로 올라갈수록 좁아지도록 경사지게 된다.In addition, vertical sides 44 are formed on both sides of the barrier rib frame 4b to a predetermined height, and inclined surfaces 43 extending upward on the vertical surfaces 44 are formed. At this time, the inclined surface 43 is inclined to become narrower as it goes up.
또한, 광 가이드판(10b), (10c)의 외주연을 형성는 측부(44)에는 격벽 플레임(4b)과 외벽 플레임(4a)의 경사면들(41),(43)에 접합되도록 하기 위하여 경사면이 형성되나 측부 경사면은 플레임의 측부 경사면(41), (43)과 대접되도록 경사지게 된다. 상기 광 가이드판의 재질은 표시패널의 상부면에 형성되는 화상을 통과시켜 사용자가 광 가이드판을 통하여 전면에서 사용자가 화상을 볼 수 있도록 하는 광투과정 재질이라면 가능하다. 또한, 표시패널의 상부면에 형성되는 화상을 넓은 평면상의 광 가이드판의 상부면을 투과시켜 사용자가 상을 보도록 하기 위하여는여러 가지의 광학적 방안이 강구될 수 있다.In addition, the inclined surface is formed on the side portion 44 forming the outer circumference of the light guide plates 10b and 10c so as to be joined to the inclined surfaces 41 and 43 of the partition frame 4b and the outer wall frame 4a. Although formed, the side inclined surface is inclined so as to be treated with the side inclined surfaces 41 and 43 of the flame. The material of the light guide plate may be a light transmission process material that allows a user to see an image from the front through the light guide plate by passing an image formed on the upper surface of the display panel. In addition, various optical methods may be devised so that the user may see the image by transmitting the image formed on the upper surface of the display panel to the upper surface of the light guide plate in a wide plane.
도 4는 본 발명의 광 가이드판의 일실시예를 설명하기 위한 단면도이다.4 is a cross-sectional view for explaining an embodiment of the light guide plate of the present invention.
도 4에 도시된 광 가이드판(10)는 광파이어버의 집속체로 이루어진 것으로, 표시패널의 상부면 전체에 걸쳐 광파이버들의 일단이 분포되어져 광 가이드판(10)의 하부면을 형성하고, 광파이버들의 타단들이 평면전체에 분포되어져 광 가이드판(10)의 상부면을 형성한다. 이때, 광 가이드판(10)의 상부면은 하부면보다 넓은 면적분포를 이루고 있기 때문에 광 파이버는 중심에서 외주연으로 향할수록 일정각도 기울어지게 형성한다. 도 4에 도시된 것은 광 가이드판(10)의 중심을 통과하는 한 단면을 도시한 것으로, 중심을 통과하는 광파이버의 중심축을 C0이라 하고, 이에 좌 우쪽으로 대칭되게 인접되는 광파이버의 중심축C1이라 하고, 이에 연속인접되는 광 파이버들의 중심축들을 C2, C3,…, Cn-1, Cn이라 할 때 단면상에 분포되는 전체적인 광파이버의 개수는 2n +1개이다. 또한, 중심축C0에서 외주연에 배치되는 광파이버의 중심축Cn까지 기울어진 경사각을 ΔΦ라 할 때, 이들 경사각은 중심축C0로부터 중심축Cn까지 균등 배분되어져야 전체적으로 균일한 화상을 얻을 수 있기 때문에 각각의 인접되는 광파이버들간의 중심축들간에는 ΔΦ/n의 각도 차이를 갖는다. 사용자는 상기와 같이 균일하게 중심의 광파이버로부터 균일하게 경사지게 설치되는 광파이버들에 의하여 하부면은 표시패널과 같으나 상부면이 하부면보다 넓은 광 가이드판을 통하여도 균일한 화상을 볼 수 있다.The light guide plate 10 illustrated in FIG. 4 is formed of a converging body of an optical fiber. One end of the optical fibers is distributed over the entire upper surface of the display panel to form a lower surface of the optical guide plate 10. The other ends are distributed throughout the plane to form the upper surface of the light guide plate 10. At this time, since the upper surface of the light guide plate 10 has a larger area distribution than the lower surface, the optical fiber is formed to be inclined at a predetermined angle from the center toward the outer periphery. 4 illustrates a cross section passing through the center of the light guide plate 10. The central axis of the optical fiber passing through the center is referred to as C 0 , and the central axis C of the optical fibers symmetrically adjacent to the left and right sides thereof. 1 , and the central axes of the adjacent optical fibers are C 2 , C 3 ,. , C n-1 , C n , the total number of optical fibers distributed on the cross section is 2n + 1. Further, the center axis C 0 central axis when referred C n ΔΦ the slanting angle of inclination to, equivalents should be allocated a uniform image as a whole to these tilt angle is the center axis C n from the center axis C 0 of the optical fiber disposed in the outer periphery in Since it can be obtained, there is an angle difference of ΔΦ / n between the central axes between each adjacent optical fibers. As described above, the user can see a uniform image even through the light guide plate having the lower surface as the display panel but the upper surface wider than the lower surface by the optical fibers uniformly inclined from the central optical fiber.
또한, 광파이버는 통상의 광파이버에서의 외층을 형성하는 클래드층이 없는 것이 광파이버의 밀도를 증가 시킬 수 있기 때문에 광 전달 효율을 높일 수 있으며, 제조시 제조원가를 줄일 수 있다.In addition, since the optical fiber has no cladding layer forming the outer layer in the conventional optical fiber, the optical fiber can increase the density of the optical fiber, thereby increasing the light transmission efficiency and reducing the manufacturing cost during manufacturing.
도 5는 본 발명의 광 가이드 판의 다른 일실시예를 도시하기 위한 단면도이다.5 is a cross-sectional view showing another embodiment of the light guide plate of the present invention.
도 5에 도시된 실시예는 광가이드판(10)의 평면중심에는 통상의 유리를 비롯한 광 투과재질로 된 투과판(10a)이 배치되고, 투과판(10a)의 외측부로 부터 외벽 프레임의 경사면(41)에 대접면까지에는 광파이버(10b)가 일정각도로 기울여져 배치되어 테두리를 형성하도록 하는 것이다.In the embodiment shown in FIG. 5, a transmissive plate 10a made of a light transmissive material including ordinary glass is disposed at the planar center of the light guide plate 10, and the inclined surface of the outer wall frame is formed from the outer side of the transmissive plate 10a. The optical fiber 10b is inclined at a predetermined angle to the opposing surface 41 to form an edge.
이와 같이 광 가이드판(10)의 중심부에는 평판의 투과판(10a)가 형성되고, 그 주변부에 광파이버(10a)가 형성되도록 함으로써 동일한 효과를 얻을 수 있다.Thus, the same effect can be acquired by making the permeation | transmission plate 10a of a flat plate in the center part of the light guide plate 10, and forming the optical fiber 10a in the peripheral part.
이와 같이, 본 발명의 상세한 설명에서는 구체적인 실시예에 관해 설명하였으나, 본 발명의 범주에서 벗어나지 않는 한도내에서 여러 가지 변형이 가능함은 물론이다. 그러므로, 본 발명의 범위는 설명된 실시예에 국한되어 정해져서는 안되며 후술하는 특허청구범위 뿐만 아니라 이 특허청구범위와 균등한 것들에 의해 정해져야 한다.As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.
