본 발명은 광파이버를 이용한 화상표시장치에 관한 것이다.The present invention relates to an image display apparatus using an optical fiber.
통상적으로 화상표시장치중의 하나인 음극선관은 고진공의 튜우브네크부에 봉입된 전자총으로부터 발생된 저자빔이 네크부의 외주면에 설치된 편향 요오크에 의해 편향된 후 스크린면의 형광점에 랜딩되어 하나의 화소를 이루게 되고 이들 화소들이 모여 하나의 화면을 이루게 된다. 그런데, 상기 음극선관은 전자총으로부터 방출된 전자빔이 스크린면으로 주사될 때에 편향요오크의 편향수차 및 새도우마스크의 도밍현상등에 의해 형광면의 화소에 정확하게 랜딩되지 않게 되므로 화면의 해상도가 저하되게 되는 문제점이 있었다. 또한 상기 음극선관은 튜우브를 유리로서 제작하게 되므로 중량이 매우 무거울 뿐만 아니라 소비전력이 매우 큰 문제점이 있었다.A cathode ray tube, which is one of the image display devices, is a low beam of electron beam enclosed in a high vacuum tubular neck portion, deflected by a deflection yoke installed on the outer circumferential surface of the neck portion, and then landed on a fluorescent point of the screen surface. Pixels are formed and these pixels come together to form a screen. However, since the cathode ray tube is not accurately landed on the pixel of the fluorescent surface due to deflection aberration of the deflection yoke and the doming phenomenon of the shadow mask when the electron beam emitted from the electron gun is scanned onto the screen surface, the resolution of the screen is deteriorated. there was. In addition, since the cathode ray tube is made of glass as a tube, there is a problem that the weight is very heavy and the power consumption is very large.
본 발명은 상기 문제점을 해결하기 위한 안출된 것으로서, 고해상도의 화면을 구현할 수 있으며 평면화가 가능할 뿐만 아니라 소비전력이 매우 적은 광파이버를 이용한 화상표시장치를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an image display device using an optical fiber that can realize a high resolution screen, can be flattened, and consumes very little power.
상기 목적을 달성하기 위하여 본 발명은 수평동기신호와 수직동기신호가 동시에 인가되어야 발광하는 다수의 각 R,G,B광원이 매트릭스상으로 배열설치된 기판과, 상기 기판의 각 광원으로부터 발광하는 빛을 각각 광전송하는 다수의 광파이버와, 상기 광파이버에 의해 전송된 빛에 의해 화상을 형성하는 스크린을 구비하여 된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a substrate in which a plurality of R, G, B light sources which emit light when a horizontal synchronous signal and a vertical synchronous signal are simultaneously applied, and light emitted from each light source of the substrate. A plurality of optical fibers for optical transmission, and a screen for forming an image by the light transmitted by the optical fiber, characterized in that the.
이하 첨부된 도면을 참조하여 본 발명에 따른 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.
제1도 내지 제3도에 나타내 보인 본 발명에 따른 광파이버를 이용한 화상표시장치(1)가 도시되어 있는바, 이는 기판(substrate; 2)상에 수직동기신호와 수평동기신호가 인가되어야 발광하는 다수의 R,G,B광원(3)(4)(5)이 매트릭스 상으로 배열설치된다. 여기에서 상기 기판(2)상에 설치된 각 광원(3)(4)(5)은 제3도에 나타내 보인 바와 같이 수직방향으로 상호 평행하게 배열된 복수의 수직동기신호라인(5)과 수평방향으로 상호 평행하게 배열된 복수의 수평동기신호라인(6)이 교차되는 부위에 설치되어 수직동기신호와 수평동기신호가 동시에 인가될 때에 발광하게 된다. 그리고 상기 기판(2)상에 설치된 각 광원(3)(4)(5)은 광파이버(7)의 일측이 연결되고 이 광파이버(7)의 타측은 스크린(8)의 배면에 접촉 배열설치되어 하나의 화소를 이루게 된다. 한편 도면에는 도시되어 있지 않으나 상기 영상신호에 따라 발광점을 지정하고 광원을 구동시키는 제어부가 더 구비된다. 그리고 상기 광파이버(7)에는 이에 연결된 R,G,B광원(3)(4)(5)의 빛에 해당하는 형광체를 넣어 광원이 꺼지더라도 소정의 시간동안 발광하도록 함이 바람직하다.An image display apparatus 1 using an optical fiber according to the present invention shown in FIGS. 1 to 3 is shown, which emits light when a vertical synchronous signal and a horizontal synchronous signal are applied on a substrate 2. A large number of R, G, B light sources 3, 4, 5 are arranged in a matrix. Here, each light source (3) (4) (5) provided on the substrate (2) is a horizontal direction and a plurality of vertical synchronous signal lines (5) arranged in parallel to each other in the vertical direction as shown in FIG. In this case, the plurality of horizontal synchronous signal lines 6 arranged in parallel to each other intersect with each other to emit light when the vertical synchronous signal and the horizontal synchronous signal are simultaneously applied. Each light source 3, 4, 5 installed on the substrate 2 is connected to one side of the optical fiber 7, and the other side of the optical fiber 7 is arranged in contact with the rear surface of the screen 8. Pixel is formed. Although not shown in the drawing, a control unit for designating a light emitting point and driving a light source according to the image signal is further provided. The optical fiber 7 may include a phosphor corresponding to the light of the R, G, and B light sources 3, 4, and 5 connected thereto to emit light for a predetermined time even when the light source is turned off.
이와 같이 구성된 본 발명 광파이버를 이용한 화상표시장치의 작용을 설명하면 다음과 같다.The operation of the image display device using the optical fiber of the present invention configured as described above is as follows.
상기 화상표시장치를 구동시키기 위해서는 먼저 제어부에 의해 수직동기신호라인(5) 중 하나의 라인을 택하고 수평동기신호(6)의 라인중 하나를 택하여 전원을 인가함으로써 R,G,B광원(3)(4)(5)을 소망하는 색상을 얻을 수 있도록 동시 또는 적어도 하나를 발광시킨다.In order to drive the image display apparatus, first, one of the lines of the vertical synchronization signal line 5 is selected by the control unit, and one of the lines of the horizontal synchronization signal 6 is applied to apply the power to the R, G, B light source ( 3) (4) (5) is made to emit light simultaneously or at least one so as to obtain a desired color.
이와 같이 하면 각 라인이 선택될 때마다 여러색의 빛을 발할 수 있으므로 상기 기판(2)상의 각 광원 전체를 구동할 수 있어 화상을 구현할 수 있게 된다.In this way, since each line is selected to emit light of various colors, the entire light source on the substrate 2 can be driven to realize an image.
이와 같이 본 발명 광파이버를 이용한 화상표시장치는 종래 음극선관의 전자총에 의해 전자빔 주사방식에 비해 해상도를 대폭 향상시킬 수 있으며 각 부품을 임의의 위치에 용이하게 배치할 수 있는 이점이 있다. 또한 본 발명은 스크린의 확장이 매우 용이하고 평면화가 가능하며 소비전력을 대폭 저감시킬 수 있는 이점이 있다.As described above, the image display apparatus using the optical fiber of the present invention can greatly improve the resolution compared to the electron beam scanning method by the electron gun of the conventional cathode ray tube, and there is an advantage that each component can be easily disposed at an arbitrary position. In addition, the present invention has the advantage that the screen is very easy to expand, planarization and power consumption can be significantly reduced.
