Description

칼라브라운관의 노광장치Color Brown Tube Exposure Equipment

본 발명은 칼라브라운관에 관한 것으로서, 특히 브라운관을 제작함에 있어 판넬내면의 형광체를 피막하기 위한 노광공정시 광원을 이동시켜 노광공정을 행하기 위한 노광장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color brown tube, and more particularly, to an exposure apparatus for carrying out an exposure process by moving a light source during an exposure process for coating a phosphor on an inner surface of a panel.

일반적으로 칼라수상관의 내측면에는 적(R), 청(B), 녹(G) 형광면이 형성되게 되는데, 이를 형성하기 위한 노광장치 및 구조는 도 1 에 도시된 바와같이 판넬(1)의 내측에 새도우마스크(2)가 프레임(3)에 용접되어 결합되고, 상기 프레임(3)은 다시 스프링(4)에 용접 결합되어 판넬(1)에 고정된 스터드핀(5)에 새도우마스크(2) 조립체가 장착되어 노광대(6) 위에 놓여지게 된다.In general, red (R), blue (B), and green (G) fluorescent surfaces are formed on the inner surface of the color receiver, and an exposure apparatus and structure for forming the same are shown in FIG. The shadow mask 2 is welded to the frame 3 and coupled to the inside, and the frame 3 is welded to the spring 4 again, and the shadow mask 2 is attached to the stud pin 5 fixed to the panel 1. The assembly is mounted and placed on the exposure table 6.

그리고 광원(9)에서 출발한 광은 광량을 조절하는 필터(8)와 광의 경로를 지정하여 주는 렌즈(7)를 통과한후, 새도우마스크(2)의 구멍을 통과하여 판넬(1)의 내면에 도 2 와 같은 형광면(16,17,18)을 형성하게 된다.The light from the light source 9 passes through the filter 8 for adjusting the amount of light and the lens 7 for designating the light path, and then passes through the hole of the shadow mask 2 to pass through the inner surface of the panel 1. Fluorescent surfaces 16, 17, and 18 are formed in FIG.

이러한 형광면의 형성을 위하여 판넬내면에 감광제를 도포하여 도 1 에 나타낸 노광대(6)의 위에서 노광을 시키게 된다.In order to form such a fluorescent surface, a photosensitive agent is applied to the inner surface of the panel to expose the light on the exposure table 6 shown in FIG.

노광순서로는 도 3 에서와 같이 R의 위치에서 노광을 실시하여 판넬내면에 R형광막을 노광하고, R 형광막의 노광이 끝나면 구동장치를 이용하여 다른 광원의 위치까지 S치 만큼 이동한후 G 형광막을 노광하고, 다시 광원을 구동장치를 이용하여 S치 이동하여 B 형광막을 노광하며, 이러한 과정을 반복함으로 판넬(1) 내면에는 형광면(16,17,18)이 형성되게 되는 것이다.In the exposure sequence, as shown in FIG. 3, exposure is performed at the position of R to expose the R fluorescent film on the inner surface of the panel. After the exposure of the R fluorescent film is completed, the G fluorescent film is moved to the position of another light source by S value using a driving device. After exposure, the light source is moved by S value using a driving device to expose the B fluorescent film, and by repeating this process, the fluorescent surfaces 16, 17, and 18 are formed on the inner surface of the panel 1.

그러나 이러한 종래 노광구조는 노광공정시 구동장치의 불안정으로 인하여 광원의 S치 이동이 정확하지 못하면 형광막의 위치가 변형되어, 이러한 형광막의 제조에 따른 오류는 브라운관의 구동시 전자빔의 미스랜딩을 유발하게 되는등의 문제점이 있었다.However, such a conventional exposure structure is the position of the fluorescent film is deformed if the S value movement of the light source is not accurate due to the instability of the driving device during the exposure process, the error caused by the manufacturing of the fluorescent film causes mis-landing of the electron beam when driving the CRT. There was a problem such as becoming.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, R, G, B 각각의 광원이 노광 s치 간격을 두고 배치되는 노광장치를 제공함으로서, 광원간격 불량으로 인한 형광체의 불균일 배열을 해결할 수 있도록 하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, by providing an exposure apparatus in which each of the light sources R, G, and B are arranged at intervals of exposure s, thereby resulting in uneven phosphors due to poor light source intervals. The goal is to allow arrays to be resolved.

109 : 광원장치109: light source device

본 발명을 도 4 를 참조하여 이하에서 상세히 설명한다.The present invention is described in detail below with reference to FIG.

먼저 본 발명의 구성을 살펴보면 새도우마스크(102)가 장착되는 판넬(101)의 내측면에 형광막을 형성시키기 위한 노광장치에 있어서, 상기 새도우마스크(102)에 형성된 전자빔통과홀을 통해 광을 주사하는 광원장치(109)에는 R, G, B 각각의 광원을 동시에 구비하였다.First, the configuration of the present invention, in the exposure apparatus for forming a fluorescent film on the inner surface of the panel 101, the shadow mask 102 is mounted, for scanning the light through the electron beam through hole formed in the shadow mask 102 The light source device 109 was provided with light sources of R, G, and B at the same time.

이와같이 구성된 상태에서 노광공정을 살펴보면 다음과 같다.Looking at the exposure process in the state configured as described above are as follows.

판넬내측면에 형광막을 형성하기 위해 도 4 의 판넬(101) 내면에 먼저 형광체를 도포한다. 그리고 도 1 의 노광대(6) 위에서 본 발명의 광원장치(109)을 이용한 노광공정을 실시하여 형광막띠를 형성시키게 된다.In order to form a fluorescent film on an inner surface of the panel, a phosphor is first applied to an inner surface of the panel 101 of FIG. 4. Then, an exposure process using the light source device 109 of the present invention is performed on the exposure table 6 of FIG. 1 to form a fluorescent film band.

이때, 본 발명의 광원장치(109)에는 G광원을 중심으로 S1 과 S2 만큼 떨어진 곳에 각각 R광원과 B광원이 위치하며, S1과 S2는 동일한 거리를 유지하고 있다. 따라서 별도의 광원장치(109) 이동이 필요없고 항상 정해진 간격만큼의 형광체띠가 판넬내면에 형성될 수 있도록 하는 것이다.At this time, in the light source device 109 of the present invention, the R light source and the B light source are positioned at positions away from the G light source by S1 and S2, respectively, and S1 and S2 maintain the same distance. Therefore, a separate light source device 109 does not need to be moved, and a phosphor strip of a predetermined interval is always formed on the inner surface of the panel.

이상 설명한 바와같이 본 발명의 노광장치는 광원의 S치 이동에 의한 오차를 줄여줌으로서 전자빔의 미스랜딩을 방지하여 이로인한 스크린의 휘도를 향상시킬 수 있는 효과가 있다.As described above, the exposure apparatus of the present invention can reduce the error caused by the S value shift of the light source, thereby preventing mis-landing of the electron beam, thereby improving the brightness of the screen.
