본 발명은 패널 형광막 형성방법에 관한 것으로, 보다 상세하게는 블랙 스트라이프를 패널에 전면적으로 형성하고, 이와동시에 상기 패널의 상,하부 일정부위에도 동일선상의 일정길이 만큼 블랙 스트라이프를 형성시켜, 선명한 화상 및 색순도를 향상시킬 수 있도록 한 패널막 형성방법에 관한 것이다.The present invention relates to a method for forming a panel fluorescent film, and more particularly, to form a black stripe on the entire surface of the panel, and at the same time to form a black stripe by a certain length on the same line in the upper and lower portions of the panel, The present invention relates to a method for forming a panel film that can improve images and color purity.
일반적으로 칼라브라운관의 패널에 형광막을 형성하기 위해서는 먼저, 패널의 내면에 블랙 스트라이프(Black Stripe)를 전면적으로 형성하는데, 이는 형광체 스트라이프 상호간격 사이에서 발생되는 산란전자에 의한 불필요한 발광을 흡수하여 밝고 어두운 부분의 명암비를 명확히 하고, 선명한 화상을 얻기 위함이다.In general, in order to form a fluorescent film on a panel of a color CRT, first, a black stripe is formed on the inner surface of the panel, which absorbs unnecessary light emitted by scattered electrons generated between the fluorescent stripe interspaces, thereby bright and dark. This is to clarify the contrast ratio of the part and to obtain a clear image.
상기 패널의 저면에 블랙 스트라이프가 형성되면 접착력강화를 위한 하도액을 그 위에 도포하여 건조 후, 패널의 내면부에 형광층을 형성하는데, 먼저 청색(B)의 형광체를 도포한 후 회수공정, 건조공정, 세정공정, 노광공정, 형상공정 등을 거쳐 스트라이프 또는 돗트(Dot)상의 청색(B)형광막을 형성하고, 같은 방법으로 녹색(G) 형광막과 적색(R) 형광막을 차례로 형성하여 형광막을 완성한다.When a black stripe is formed on the bottom of the panel, a coating solution for strengthening adhesion is applied thereon and dried, and then a fluorescent layer is formed on the inner surface of the panel. First, a blue (B) phosphor is applied, and then a recovery process and drying. A blue (B) fluorescent film is formed in a stripe or dot shape through a process, a cleaning process, an exposure process, a shape process, and the like, and in the same manner, a green (G) fluorescent film and a red (R) fluorescent film are sequentially formed to form a fluorescent film. Complete
이후, 청색(B), 녹색(G), 적색(R)으로 형성된 형광막 스트라이프는 형광체 입자에 의해 요철로 되어 있기 때문에 알루미늄을 진공증착 시키게 되면, 알루미늄막이 형광체막의 요철사이로 침투하여 막을 이루게 되어 반사효과를 감소시키므로 이를 방지하기 위해 락카막을 도포한 후, 그 위에 알루미늄을 진공증착시켜 패널 공정을 완료한다.Subsequently, since the fluorescent film stripe formed of blue (B), green (G), and red (R) is uneven by phosphor particles, when aluminum is vacuum-deposited, the aluminum film penetrates into the unevenness of the phosphor film to form a film and reflects it. To prevent this, the lacquer film is applied to prevent this effect, and then aluminum is vacuum deposited thereon to complete the panel process.
그런데, 상기와 같은 방법으로 이루어진 패널은 첨부된 예시도면 제1도에 도시된 바와 같이 패널(10)의 상,하부위는 돗트의 크기 차이에 의해 형광막(12)의 높이가 동일하지 못하여, 형광체 스트라이프 상호간격사이에서 발생되는 산란전자에 의한 불필요한 발광을 정확하게 흡수하지 못하고, 이에따라 밝고 어두운 부분의 명암이 명확하지 못하며, 아울러 선명한 화상 및 색순도를 저하시키는 문제점이 있었다.However, the panel made by the above method is as shown in Figure 1 of the accompanying drawings, the upper and lower portions of the panel 10 is not the same height of the fluorescent film 12 due to the difference in the size of the dots, There is a problem in that it is not possible to accurately absorb the unnecessary light emission by the scattering electrons generated between the fluorescent stripe interspace, and therefore the brightness and darkness of the bright and dark portions are not clear, and the sharp image and the color purity are deteriorated.
본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 블랙 스트라이프를 패널에 전면적으로 형성하고, 이와동시에 상기 패널의 상,하부 일정부위에도 동일선상의 일정길이 만큼 블랙 스트라이프를 형성시켜, 형광체 스트라이프 상호 간격사이에서 발생되는 산란전자에 의한 불필요한 발광을 정확하게 흡수하고, 이에따라 밝고 어두운 부분의 명암비를 명확히 하여 주며, 아울러 선명한 화상 및 색순도를 향상시킬 수 있도록 한 패널막 형성방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, the black stripe is formed entirely on the panel, and at the same time to form a black stripe by a certain length on the same line in the upper and lower portions of the panel, the fluorescent stripe It is an object of the present invention to provide a method for forming a panel film that accurately absorbs unnecessary light emission caused by scattering electrons generated between the gaps, clarifies contrast ratios of bright and dark areas, and improves clear images and color purity. .
상기와 같은 목적을 달성하기 위한 본 발명은 칼라브라운관의 패널 형광막 형성방법에 있어서, 상기 패널의 내면과 상,하부위의 동일선상에 일정길이 만큼 블랙 스트라이프를 형성하는 단계와, 상기 블랙 스트라이프가 형성되면 접착력강화를 위한 하도액을 그 위에 도포하여 건조 시키는 단계와, 상기 패널 건조 단계 후, 청색(B)의 형광체를 도포한 다음 회수공정, 건조공정, 세정공정, 노광공정, 현상공정 등을 거쳐 스트라이프 또는 돗트(Dot)상의 청색(B), 녹색(G), 적색(R) 형광막을 차례로 형성하는 단계와, 상기 형광막 형성 단계 후, 반사효과의 감소를 방지하기 위해 락카막을 도포한 다음, 그 위에 알루미늄을 진공증착시키는 단계로 이루어진 방법으로서, 어두운 부분의 명암비를 명확히 하여 주며, 아울러 선명한 화상 및 색순도를 향상시킬 수 있는 점에 특징이 있다.In order to achieve the above object, the present invention provides a method for forming a panel fluorescent film of a color brown tube, the method comprising: forming a black stripe by a predetermined length on the same line as an upper surface and a lower portion of an inner surface of the panel; When it is formed, the step of applying a coating solution for enhancing the adhesive strength thereon to dry, and after the panel drying step, the blue (B) phosphor is applied, and then the recovery process, drying process, cleaning process, exposure process, development process, etc. After the step of forming a blue (B), green (G), red (R) fluorescent film on a stripe or dot, and then forming the fluorescent film, after applying the lacquer film to prevent the reduction of the reflection effect In addition, vacuum deposition of aluminum on the method, which makes it possible to clarify the contrast ratio of the dark part, and also improve the clear image and color purity. It is characterized in the point.
이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 발명의 패널 형광막 형성방법에 의한 형성된 패널을 나타낸 것으로, 상기 패널(10)의 내면에 형광막(12)을 형성하기 위해서는 먼저, 패널(10)의 내면에 블랙 스트라이프(Black Stripe)(20)를 전면적으로 형성하는데, 이때, 상기 패널(10)의 상,하부 일정부위에 동일선상으로 일정길이 만큼 블랙 스트라이프(20)를 형성한다.2 illustrates a panel formed by the method of forming a panel fluorescent film of the present invention. In order to form the fluorescent film 12 on the inner surface of the panel 10, first, a black stripe is formed on the inner surface of the panel 10. ) Is formed on the entire surface, and the black stripe 20 is formed on the upper and lower portions of the panel 10 by a predetermined length in the same line.
그리고, 상기 패널(10)의 저면에 블랙 스트라이프(20)가 형성되면 접착력 강화를 위한 하도액을 그 위에 도포하여 건조 후 패널(10)의 내면부에 R.G.B 형광막(12)을 차례로 형성하여 완성한다.When the black stripe 20 is formed on the bottom surface of the panel 10, an undercoat liquid for strengthening adhesive strength is applied thereon, followed by drying to form an RGB fluorescent film 12 on the inner surface of the panel 10 in order. do.
이후, 청색(B), 녹색(G), 적색(R)으로 형성된 형광막(12)은 형광체 입자에 의해 요철로 되어 있기 때문에 알루미늄을 진공증착시키게 되면, 알루미늄막이 형광막(12)의 요철사이로 침투하여 막을 이루게되어 반사효과를 감소시키므로 이를 방지하기 위해 락카막을 도포한후, 그 위에 알루미늄을 진공증착시켜 패널의 형광막 공정을 완료한다.Subsequently, since the fluorescent film 12 formed of blue (B), green (G), and red (R) is uneven by the phosphor particles, when aluminum is vacuum-deposited, the aluminum film is formed between the unevenness of the fluorescent film 12. Since it penetrates and forms a film to reduce the reflection effect, a lacquer film is applied to prevent this, and aluminum is vacuum deposited thereon to complete the fluorescent film process of the panel.
즉, 본 발명은 첨부된 예시도면 제2도에 도시된 바와 같이 블랙 스트라이프(20)를 패널(10)에 전면적으로 형성하고, 이와동시에 상기 패널(10)의 상,하부 일정부위에도 동일선상의 일정길이 만큼 블랙 스트라이프(20)를 형성시켜, 상기 돗트의 크기 차이에 의한 형광막(12)의 높이가 일정함으로써, 형광막(12)의 상호 간격사이에 발생되는 산란전자에 의한 불필요한 발광을 정확하게 흡수하고, 이에따라 밝고 어두운 부분의 명암비를 명확히 하여 주며, 아울러 선명한 화상 및 색순도를 향상시키는 효과가 있다.That is, according to the present invention, as shown in FIG. 2 of the accompanying drawings, the black stripe 20 is formed on the entire surface of the panel 10, and at the same time, the upper and lower portions of the panel 10 are arranged on the same line. By forming the black stripe 20 by a predetermined length, and the height of the fluorescent film 12 due to the difference in the size of the dot is constant, unnecessary light emission by scattered electrons generated between the mutual gaps of the fluorescent film 12 accurately Absorption, thereby clarifying the contrast ratio of the light and dark parts, and also has the effect of improving the clear image and color purity.
