Description

도어폰용 음극선관{cathode-ray tube for doorphone}Cathode ray tube for doorphones {cathode-ray tube for doorphone}

본 발명은 도어폰등에 사용되는 음극선관(CRT)에 관한것으로서, 이를 좀더 구체적으로 설명하자면 음극선관의 화상표시글래스 내면에 형광물질을 다양한 방법으로 코팅할 수 있도록 하고, 이와 아울러 음극선관을 보다 용이하게 제조할 수 있도록 하여 음극선관의 생산능률을 높일 수 있도록 한것이다.The present invention relates to a cathode ray tube (CRT) used in door phones, etc. To describe in more detail, it is possible to coat the fluorescent material on the inner surface of the image display glass of the cathode ray tube in various ways, and also to facilitate the cathode ray tube. It can be manufactured so that the production efficiency of cathode ray tube can be improved.

일반적으로 음극선관이라 함은 전자빔을 화상표시 글래스 내면의 형광면에 쏘아 광학적인 상으로 변환하여 영상, 문자, 도형 등을 표시하는 것을 말하고, 그 구조를 간략하게 설명하면 음극선관은 크게 판넬(PANEL)과 퍼널(FUNNEL)로 구성된다. 도어폰용 음극선관의 판넬은 프론터글래스(frontglass)와, 형광체가 코팅된 곡률형 화면표시글래스를 가지는 리어글래스 (rearglass)로 구성된다. 즉, 통상적인 도어폰용 음극선관은 퍼널,프론트글래스,리어글래스로 3등분 되고 이들을 열융착으로 접착함으로써 제조되게 되는 것이다.In general, a cathode ray tube refers to an electron beam that is shot on a fluorescent surface on an inner surface of an image display glass and converted into an optical image to display an image, text, or a figure. Briefly, the structure of the cathode ray tube is largely a panel. And funnel (FUNNEL). The panel of the cathode ray tube for the door phone is composed of a front glass and a rear glass having a curvature-type display glass coated with a phosphor. That is, the cathode ray tube for a door phone is divided into three parts into a funnel, a front glass, a rear glass, and is manufactured by bonding them by heat fusion.

그러나 종래의 3등분형 도어폰용 음극선관(1)은 첨부도면 도 5에서와 같이 리어글래스(4)의 화면표시글래스(41) 상부와 양측테두리에 벽면이 형성되어 있으므로 화면표시글래스(41) 내면에 형광물질 코팅방법이 한정되게된다.However, the conventional cathode ray tube 1 for three-quarter type door phone has a wall surface formed on the upper surface of the screen display glass 41 and both edges of the rear glass 4, as shown in FIG. In the fluorescent coating method is limited.

이를 좀더 상세히 설명하면 리어글래스(4)의 테두리에 형성되는 벽면으로 인하여 인쇄법이나 사진식각법(spincoatg)등으로는 형광물질을 코팅할 수 없어 전기영동법(electrophorethic method)으로 만 형광물질을 코팅할 수 밖에 없는 문제점이 있었다.In more detail, due to the wall surface formed on the edge of the rear glass 4, the fluorescent material cannot be coated by the printing method or the spincoatg, and thus the fluorescent material may be coated only by the electrophorethic method. There was nothing but a problem.

이러한 전기영동법은 작업이 난이할 뿐만 아니라 그 작업시간도 오래걸려 음극선관 제조공정 중 형광물질 코팅공정에서 많은 시간이 낭비되었고 이는 음극선관의 생산능률 저하를 초래하여 음극선관의 생산원가를 높이는 주요원인이 되어왔다.This electrophoresis method is not only difficult, but also takes a long time, and a lot of time was wasted in the fluorescent material coating process of the cathode ray tube manufacturing process, which leads to a decrease in the production efficiency of the cathode ray tube, thereby increasing the production cost of the cathode ray tube. This has been.

본 발명은 위와같이 음극선관을 제조함에 있어,나타나는 종래의 문제점을 한꺼번에 해결하기 위함에 그 기술적인 과제를 두고 발명된 것으로서, 특히 음극선관의 화면표시글래스 내면에 여러가지 코팅방법으로 형광물질을 코팅할 수 있고, 음극선관의 제조능률도 높일 수 있는 음극선관에 관한것이다.The present invention has been invented with the technical problem in order to solve the conventional problems appearing at the same time, as described above, in particular, the fluorescent material to be coated on the inner surface of the display glass of the cathode ray tube by various coating methods. The present invention relates to a cathode ray tube which can improve the manufacturing efficiency of the cathode ray tube.

퍼널(FUNNEL)과 프론트글래스(frontglass) 및 리어글래스(rearglass)로 분리 구성되는 통상적인 음극선관(1)에 있어서, 리어글래스(4)를 서로 열융착되는 지지글래스(401)와, 내면에 형광물질(5)이 코팅되는 화면표시글래스(402)로 분리 구성하여 음극선관(1)을 4등분화 하되, 화면표시글래스(402)를 평판으로 형성하여서된 것이고,In the conventional cathode ray tube (1) consisting of a funnel (FUNNEL), front glass (front glass) and rear glass (rearglass), the support glass 401 for thermally sealing the rear glass (4) and the inner surface of the fluorescent lamp The cathode ray tube 1 is divided into four sections by separating the display glass 402 from which the material 5 is coated, and forming the display glass 402 into a flat plate.

또한 상기에서 화면표시글래스(402) 하단의 융착부(402-1)를 일정한 각도로경사지게 형성하여서된 것이다.In addition, the fusion unit 402-1 at the bottom of the screen display glass 402 is formed to be inclined at a predetermined angle.

이와같이 된 본 발명은 리어글래스(4)의 화면표시글래스(402)가 지지글래스 (401)와 별도 성형되므로 퍼널(2),프론트글래스(3),리어글래스(4)를 서로 열융착하여 음극선관(1)을 제조하기 전에 리어글래스(4)의 화면표시글래스(402)의 내면에 형광물질(5)을 코팅할 수 있게되며,According to the present invention, the display glass 402 of the rear glass 4 is separately formed from the support glass 401, so that the funnel 2, the front glass 3, and the rear glass 4 are thermally fused to each other to form a cathode ray tube. Before manufacturing (1), the fluorescent material 5 can be coated on the inner surface of the display glass 402 of the rear glass 4,

또한 상기에서 리어글래스(4)의 화면표시글래스(402) 하단의 융착부(402-1)를 일정한 각도로 경사지게 형성한것은 화면표시글래스(402)와 퍼널(2)을 열융착할 때 그 접착경계부에 공간이 발생되지 않도록 하기 위함인것이다.In addition, the fusion unit 402-1 at the bottom of the screen display glass 402 of the rear glass 4 is inclined at a predetermined angle so that the adhesion of the screen glass 402 and the funnel 2 when heat-sealed. This is to prevent space from occurring at the boundary.

따라서 본 발명은 상기한 바와 같이 음극선관(1)을 제조하기 전에 화면표시글래스(402)만 분리하여 그 내면에 형광물질(5)을 코팅할 수 있으므로 형광물질(5) 코팅법을 다양화할 수 있게된다. 즉, 화면표시글래스(402)만을 별도의 코팅장치에 투입하여 형광물질(5)을 코팅할 수 있기때문에 인쇄법이나 사진식각법등을 이용하여 형광물질(5)을 코팅할 수 있게되는 효과가 있고, 이는 음극선관(1)을 제조함에 있어 형광물질(5) 코팅작업에 시간을 절약할 수 있게 되어 음극선관(1)의 생산원가 하락을 도모할 수 있게되는 이점이 있으며, 또한 상기의 화면표시글래스(402)를 평판으로 형성하게되면 이 또한 내면의 형광물질(5) 코팅 방법을 더욱더 다양화할 수 있게되는 장점이 있게되는 것이다.Therefore, the present invention can diversify the fluorescent material (5) coating method because it is possible to coat the fluorescent material (5) on the inner surface by separating only the display glass 402 before manufacturing the cathode ray tube (1) as described above Will be. That is, since only the screen display glass 402 can be put into a separate coating device to coat the fluorescent material 5, the fluorescent material 5 can be coated using a printing method or a photolithography method. This is advantageous in that the manufacturing cost of the cathode ray tube 1 can be reduced by saving time in coating the fluorescent substance 5 in manufacturing the cathode ray tube 1, and the screen display described above. Forming the glass 402 into a flat plate also has the advantage that it is possible to further diversify the coating method of the fluorescent material 5 on the inner surface.
