본 발명은 대화면 박막 디스플레이에 관한 것으로 더 상세히 말하면 다수의 박막 디스플레이를 인접 배치하여 멀티비젼화 하면서 별도 고안한 벌집 구조의 도광판을 이용하여 개별 박막 디스플레이간의 프레임이 보이지 않게 하여 하나의 큰 디스플레이로 만드는 복합 영상 표시 장치에 관한 것이다.The present invention relates to a large-screen thin film display. More specifically, a plurality of thin film displays are arranged adjacent to each other and multi-visionized to make a single large display by making a frame between individual thin film displays invisible using a light guide plate having a honeycomb structure separately designed. It relates to a video display device.

기존의 벽걸이형 대화면 박막 디스플레이는 TFT-LCD와 PDP가 대표적이다. TFT-LCD와 PDP는 제조 공정의 수율과 관련되어 그 크기와 해상도가 한계가 있는 실정이다. TFT-LCD는 이름이 의미하듯이 thin film transistor의 배치 밀도에 의하여개별화소가 결정된다. 일반적으로 많이 사용되고 있는 15인치 TFT-LCD 패널의 경우 1024×768화소로 고정되어 있다. 현재 40인치까지 발표되고 있으나 경제적인 크기는 30인치 이하이다. PDP는 개별 화소마다 가스 봉입 방전관에 의하여 플라즈마 방전으로 형광체 발광을 이루고 있으므로 R, G, B 3색을 이루는 하나의 화소 크기가 약 1mm 정도이므로 100만 화소정도의 구성을 위해서는 일정한 크기가 요구된다. 따라서 소형 디스플레이는 구성하기 어려우며 40인치 이상이 만들어지고 있다. 현재 최대 63인치, 130만 화소까지 출시되어 있다. 이러한 크기와 해상도는 과거에 비하여 장족의 발전을 하였지만 현재 확산되어 가는 HDTV 방송 규격에도 크게 못 미치는 실정이다. 현재 확정된 HDTV 방송의 최대 화소량은 1920×1080으로서 약 200만 화소에 이르고 있다.Conventional wall-mounted large screen thin-film displays are typical of TFT-LCD and PDP. TFT-LCD and PDP are limited in size and resolution in relation to the yield of the manufacturing process. In TFT-LCD, as the name implies, individual pixels are determined by the density of the thin film transistors. In general, the 15-inch TFT-LCD panel which is widely used is fixed at 1024 × 768 pixels. It is currently announced up to 40 inches, but the economic size is less than 30 inches. Since the PDP emits phosphors by plasma discharge by gas-filled discharge tubes for each pixel, a size of one pixel of three colors of R, G, and B is about 1 mm, and thus a certain size is required for the configuration of about 1 million pixels. As a result, small displays are difficult to configure and more than 40 inches are being made. Currently, it is up to 63 inches and 1.3 million pixels. These sizes and resolutions have evolved significantly compared to the past, but are far short of the current HDTV broadcasting standards. Currently, the maximum pixel amount of the HDTV broadcast that has been determined is 1920 × 1080, which is about 2 million pixels.

손실 없이 영상을 표시하고자 할 때 디스플레이의 화소량이 원 영상의 화소량 보다 커야 원 영상은 화질 손상이 없이 표현된다. 그러므로 HDTV 방송에 대응한 디스플레이는 200만 화소 이상의 구성이 요구된다. 즉 디스플레이의 화소가 1920×1080의 수배에 화소에 이르면 디지털 영상 처리 기법을 이용하여 훨씬 향상된 영상을 보일 수 있게되고 다중 화면 구성 등에 대하여 많은 유연성을 제공할 수 있게된다.When the image is to be displayed without loss, the pixel amount of the display is larger than the pixel amount of the original image so that the original image is represented without loss of image quality. Therefore, a display corresponding to HDTV broadcasting requires a configuration of 2 million pixels or more. In other words, when the pixel of the display reaches the pixel of 1920 × 1080, the digital image processing technique can be used to show a much improved image and provide a lot of flexibility for the multi-screen configuration.

본 발명의 목적은 기존의 벽걸이형 박막 디스플레이의 문제점을 해결하기 위한 것으로서, 다수의 박막 디스플레이를 인접 배치하여 멀티비젼화 하면서 별도 고안한 벌집 구조의 도광판을 이용하여 개별 박막 디스플레이간의 프레임이 보이지 않게 하여 하나의 큰 디스플레이로 만드는 복합 영상 표시 장치이다. 그러므로 표현화소량과 크기의 최대 한계치가 없어지면서 전체 패널의 두께를 10cm이하로 유지할 수 있는 장점을 지닌다.An object of the present invention is to solve the problems of the conventional wall-mounted thin film display, by using a light-guide plate of a honeycomb structure designed separately while multi-vision by placing a plurality of thin film display adjacent to the frame between the individual thin-film display It is a composite video display device that makes one large display. Therefore, the maximum limit of the display pixel quantity and size is eliminated, and the overall panel thickness can be kept below 10 cm.

다음으로 본 발명에 따른 고속 영상 검사 시스템의 바람직한 실시 예를 도면을 참조하여 상세하게 설명한다. 먼저 도 1에 나타낸 바와 같이, 본 발명에 따른 대형 벽걸이형 박막 디스플레이의 일실시 예는 백 라이트를 포함한 15인치 TFT-LCD를 가로 4장, 세로 3장씩 총 12장을 하나의 기본 프레임에 배치한다. 단면 A-A'에서 본 그림과 같이 하부의 메인 프레임 위에 TFT-LCD 패널이 놓인다. 그 다음 벌집 구조의 도광판을 전면에 올려놓은 다음 마지막으로 5mm 정도의 보호용 유리 혹은 투명 복합 아크릴 수지 판재로 마감 처리한다. 기존의 15인치 TFT-LCD는 가로, 세로의 비율이 4:3로서 1024×768화소로 구성되어 있다. 반면 HDTV는 16:9의 화면 비율이 요구되므로 15인치 TFT-LCD를 4×3으로 배치하면 16:9의 화면 비율이 자연스럽게 얻어지게된다. 이 구성은 일 실시 예이므로 요구되는 크기에 따라 다양한 배치가 이루어질 수 있다.Next, a preferred embodiment of the high speed imaging system according to the present invention will be described in detail with reference to the drawings. First, as shown in FIG. 1, one embodiment of a large wall-mounted thin film display according to the present invention arranges a total of 12 sheets of 15-inch TFT-LCDs including a backlight and 3 sheets of 3 sheets each in a single basic frame. . TFT-LCD panel is placed on the lower main frame as shown in the cross section A-A '. Then, the honeycomb light guide plate is put on the front and finally finished with 5mm protective glass or transparent composite acrylic resin sheet. Existing 15-inch TFT-LCD has 4: 3 aspect ratio and consists of 1024 × 768 pixels. On the other hand, since HDTV requires a 16: 9 aspect ratio, placing a 15-inch TFT-LCD in 4 × 3 will naturally yield a 16: 9 aspect ratio. Since this configuration is an embodiment, various arrangements may be made according to the required size.

본 발명의 구성품 중 가장 중요한 도광판은 도 2의 구조를 이루고 있다. 단면 A-A'에서 보아 TFT-LCD 패널은 액정 디스플레이 면(22)과 패널 프레임(24)으로 나누어지며 화면은 액정 디스플레이 면(22)에 만 나타나므로 도광판은 빛을 전달 확산시켜 패널 프레임(24)이 최종 디스플레이 면에 나타나지 않도록 한다. 도광판의 프레임은 도 2와 같이 하부가 좁고 상부가 넓은 개구부를 지닌 구조로서 그 단면은사다리꼴을 이룬다. 그리고 도광판을 이루는 광 섬유 다발은 PE(폴리 에치렌)수지로 압출한 지름 0.5∼1.0mm의 광섬유를 30∼50mm 정도 일정한 길이로 잘라서 개별 프레임의 내부에 빈틈없이 세운다. 본 발명의 실시 예로서 프레임은 15인치 TFT-LCD 규격에 따르며 도 2에 나타낸 것은 단면이 사다리꼴인 프레임은 단면 A-A'의 경우 하부의 길이는 약300mm, 상부의 길이는 약 310mm이다. 이 프레임의 내부에 지름 1mm의 광섬유를 하부인 바닥 면에는 빈틈없이 놓게되면 총 300개의 광섬유가 배치되고 위쪽은 광섬유와 광섬유 사이에 0.033mm의 틈이 형성되어 사다리꼴 프레임에 꽉 차게 배치되고 인접 도광판의 프레임에 배치된 광섬유 다발과 틈이 없이 배열된다. 즉 광섬유 다발은 하부의 300mm에 배열된 화소 정보를 상부의 310mm폭에 확산 배치되도록 전송하는 광로가 된다.The most important light guide plate of the components of the present invention has the structure of FIG. As seen from the cross-section A-A ', the TFT-LCD panel is divided into the liquid crystal display surface 22 and the panel frame 24, and the screen appears only on the liquid crystal display surface 22, so that the light guide plate transmits and diffuses light so that the panel frame 24 ) Does not appear on the final display side. As shown in FIG. 2, the light guide plate has a narrow bottom portion and a wide top portion, and has a trapezoidal cross section. The optical fiber bundle constituting the light guide plate is cut into 0.5-50 mm diameter optical fibers extruded by PE (poly ethylene) resin into a constant length of about 30-50 mm, and is erected inside the individual frame. As an embodiment of the present invention, the frame conforms to the 15-inch TFT-LCD standard, and the frame shown in FIG. 2 has a trapezoidal cross section in the case of cross section A-A ', and the length of the lower portion is about 300 mm and the length of the upper portion is about 310 mm. When the optical fiber with a diameter of 1mm is placed on the bottom of the frame without any gaps, a total of 300 optical fibers are arranged, and a gap of 0.033mm is formed between the optical fibers and the optical fibers, and the upper part is placed tightly on the trapezoidal frame, It is arranged without gaps and optical fiber bundles arranged in the frame. In other words, the optical fiber bundle is an optical path for transmitting the pixel information arranged at the lower part of 300mm so as to be diffused and disposed at the upper part of 310mm.

상기와 같이 구성되고 작동되는 본 발명에 따른 대형 벽걸이형 박막 디스플레이에 의하면, 소형 TFT-LCD를 여러 장 인접 배치하여 연결함으로서 벽걸이형 박막 디스플레이의 대형화가 쉽게 이루어진다. 벽걸이형 박막 디스플레이의 대형화는 TFT-LCD나 PDP외의 어떤 방법에서도 제조 공법에서 한계를 보이고 있다. 따라서 한계가 없는 대형화는 매우 큰 장점이 된다. 특히 본 발명의 일 실시 예와 같이 여러 장의 TFT-LCD의 인접 배치로 형성시킨 대형 디스플레이는 TFT-LCD 개수만큼 표현 화소가 늘어나게 되어 매우 높은 해상도의 디스플레이가 손쉽게 만들어진다. TFT-LCD와 본 발명에 따른 도광판 그리고 프레임 등의 두께를 합쳐도 여전히100mm이하의 두께가 유지된다. TFT-LCD의 면적 당 가격은 크기가 커질수록 증가하므로 가장 경제적인 크기의 TFT-LCD를 선택하여 배열하여 대형화를 이루면 대형화와 박형, 고해상도와 더불어 저가격의 디스플레이가 이루어진다. 특히 이때 구현되는 수백만 화소의 디스플레이는 HDTV 모니터와 컴퓨터의 데이터 터미널에 혼용할 수 있으며 다중 디스플레이 터미널로 이용하여도 화질의 손실이 없이 여러 가지 정보를 혼합하여 표시할 수 있는 장점이 있다.According to the large wall-mounted thin film display according to the present invention constructed and operated as described above, the wall-mounted thin film display can be easily enlarged by connecting a plurality of small TFT-LCDs adjacently arranged. Increasing the size of wall-mounted thin-film displays has shown limitations in manufacturing methods in any method other than TFT-LCD or PDP. Therefore, the large size without a limit is a very big advantage. In particular, a large display formed of a plurality of TFT-LCDs adjacent to each other, as shown in an embodiment of the present invention, may increase the number of display pixels by the number of TFT-LCDs, thereby easily making a display having a very high resolution. Even if the thickness of the TFT-LCD, the light guide plate and the frame according to the present invention is combined, the thickness of 100 mm or less is still maintained. Since the price per area of TFT-LCD increases as the size increases, selecting and arranging the most economical TFT-LCD to achieve a large-scale, low-cost display with large-sized, thin and high resolution is achieved. In particular, the multi-million-pixel display implemented at this time can be used for data terminals of HDTV monitors and computers, and even when used as multiple display terminals, a mixture of various information can be displayed without loss of image quality.
