본 발명은 패널의 형광체막 형성방법에 관한 것으로 보다 상세하게는 형광체막의 외면에 형성되는 알루미늄막의 알루미늄 증착량을 정확하게 설정하여, 형광체의 소실을 방지하고, 이에따른 형광체의 발광을 효율적으로 극대화 할 수 있도록 한 패널의 알루미늄막 증착방법에 관한 것이다.The present invention relates to a method for forming a phosphor film of a panel, and more particularly, to accurately set an aluminum deposition amount of an aluminum film formed on an outer surface of a phosphor film, to prevent the loss of phosphor, and to maximize the light emission of the phosphor accordingly. The present invention relates to a method for depositing an aluminum film of a panel.
일반적으로, 브라운관은 여러가지 부품으로 이루어져 있고, 그 중에서 브라운관의 전면에는 패널이 갖추어져 있다. 이 패널은 여러공정을 거쳐 완성되는데, 브라운관 화면부의 3색형광막을 형성시키기 위한 스크린 공정이 있다. 이 스크린 공정은 블랙코팅(Black Coating : 이하 BC라 약칭함)공정과 스크린 코팅(Screen Coating : 이하 SC라 약칭함)공정으로 구분할 수 있다.In general, the CRT consists of various components, among which the front panel of the CRT is provided with a panel. This panel is completed through several processes, and there is a screen process for forming a tricolor fluorescent film of the CRT screen part. This screen process can be divided into a black coating process (hereinafter abbreviated as BC) process and a screen coating process (hereinafter abbreviated as SC) process.
상기 BC공정은 형광체 스트라이프 상호간격 사이에 생기는 산란전자에 의한 불필요한 발광을 흡수하거나 외광을 흡수하여 밝고 어두운 부분의 명암비를 명확히 하므로써, 선명한 화상을 얻게하기 위해 무반사 흑색도료를 패널의 내면에 도포하는 공정이다.The BC process is a process of applying an anti-reflective black paint to the inner surface of the panel to obtain a clear image by absorbing unnecessary light emission by the scattering electrons generated between the fluorescent stripe interspace or by absorbing external light to clarify the contrast ratio of the bright and dark areas to be.
또한 SC공정은 형성된 블랙 스트라이프 사이의 홀에 칼라를 나타내는 3색의 형광체를 순차적으로 도포하고, 그 위에 알루미늄 증착에 의한 형광체 입자의 손상방지 및 알루미늄의 경면성 향상을 위한 유기수지막을 도포하는 공정인 것이다.In addition, the SC process is a process of sequentially applying a phosphor of three colors representing the color to the holes between the formed black stripes, and coating an organic resin film for preventing damage to the phosphor particles by aluminum deposition and improving the mirror properties of aluminum thereon. will be.
그런데, 상기 형광체막에 알루미늄막을 일정하게 형성하지 않는 경우, 브라운관의 전자총에서 발사된 전자빔이 형광면에 닿아 발광하지만 그 발광한 빛이 패널 표면에 닿아 약 50%가 반사되어 실제로 약 50%의 광이 표면으로 나오는 것에 지나지 않는 문제점이 있었다.However, when the aluminum film is not uniformly formed on the phosphor film, the electron beam emitted from the electron gun of the CRT touches the fluorescent surface and emits light, but the emitted light reaches the surface of the panel and reflects about 50% of the light. There was only a problem coming out of the surface.
또한, 상기 전자총에서 발사된 전자빔은 양극 고전압으로 가속되어 형광면에 부딪쳐 발광하게 되나, 상기 전자빔이 형광면에 도달하기전에 관내 미량의 가스와 충돌로 인하여 가스가 분해 되어 이온이 발생하게 된다.In addition, the electron beam emitted from the electron gun is accelerated to the anode high voltage and hit the fluorescent surface to emit light, but before the electron beam reaches the fluorescent surface, the gas is decomposed due to collision with a small amount of gas in the tube to generate ions.
여기서, 발생된 이온은 양극전압으로 가속되어 형광체막에 충돌하게 되는데, 이 형광면은 이온에 대하여 매우 약하여 상기 형광체막이 타게되는 문제점이 있었다.Here, the generated ions are accelerated by the anode voltage to collide with the phosphor film, the phosphor surface is very weak against the ion has a problem that the phosphor film burns.
또한, 상기 이온에 의해 형광체막이 타는 것을 방지하고자, 형광체막 표면에 알루미늄 증착을 시키게 되는 바, 상기 알루미늄막 증착량은 브라운관의 크기 및 양극 전압과의 관계를 고려하지 않으면, 형광막의 발광을 저하시키고 이에따른 휘도가 저하되는 문제점이 있었다.In addition, in order to prevent the phosphor film from burning due to the ions, aluminum is deposited on the surface of the phosphor film, and the aluminum film deposition amount is lowered if the amount of the aluminum film is not considered in relation to the size of the CRT and the anode voltage. As a result, there was a problem that the luminance is lowered.
본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 형광체막 외면에 형성되는 알루미늄막의 증착량을 정확하게 설정하여, 형광막체의 소실을 방지하고 이에따른 형광체의 발광을 효율적으로 극대화시켜 휘도를 향상시킬 수 있도록 한 패널의 알루미늄막 증착방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, by accurately setting the deposition amount of the aluminum film formed on the outer surface of the phosphor film, to prevent the loss of the phosphor film and to maximize the resulting light emission of the phosphor to improve the brightness It is an object of the present invention to provide a method for depositing an aluminum film of a panel.
상기와 같은 목적을 달성하기 위한 본 발명은 패널의 내주면에 형성되는 형광체막의 손상을 방지하도록 된 패널의 알루미늄막 증착방법에 있어서, 상기패널의 내주면에 블랙 스트라이프를 형성하는단계와, 상기 단계후, 블랙 스트라이프 사이의 홀에 칼라를 나타내는 형광체를 순차적으로 도포하는 단계와, 상기 단계후, 형광체막 위에 형성되는 알루미늄막의 증착량을 3∼3.5%로 증착시키는 단계로 이루어진 것으로, 형광체 입자의 손상을 방지하여 이 형광막의 발광을 향상시키며, 이에따라 휘도가 향상되는 점에 특징이 있다.According to an aspect of the present invention, there is provided a method of depositing an aluminum film of a panel to prevent damage to a phosphor film formed on an inner circumferential surface of a panel, the method comprising: forming a black stripe on an inner circumferential surface of the panel; Sequentially applying a phosphor representing a color to the holes between the black stripes, and depositing the deposition amount of the aluminum film formed on the phosphor film at 3 to 3.5% after the step, thereby preventing damage to the phosphor particles. This improves the light emission of the fluorescent film, and thus the luminance is improved.
이하 본 발명은 첨부된 예시도면 제1도에 나타낸 바와같이 먼저, 패널(10)의 내주면에 블랙 스트라이프 사이의 홀에 칼라를 나타내는 3색의 형광체를 순차적으로 도포하고, 그 위에 형성되는 알루미늄막(14)의 증착량을 3∼3.5%로 증착을 시킴으로써, 형광체 입자의 손상을 방지하고, 이에따른 형광체막(16)의 발광을 효율적으로 극대화 하여 결국, 휘도를 향상시키게 되는 효과가 있다.Hereinafter, as shown in FIG. 1 of the accompanying drawings, first, three colors of phosphors having color marks are sequentially applied to the inner circumferential surface of the panel 10, and an aluminum film formed thereon is formed thereon. By depositing the deposition amount of 14) at 3 to 3.5%, damage to the phosphor particles is prevented, thereby maximizing the light emission of the phosphor film 16, thereby improving brightness.
