Claims (1)

형광체 스크린과 상기 형광체 스크린에 근접대향한 위치에 고정된 새도우 마스크와 상기 새도우 마스크를 지지하는 프레임과 상기 새도우 마스크를 매개로 하여 전자빔을 형광체 스크린 각 화소에 방사하는 전자총과 상기 전자총에서 방사된 전자빔의 지자기 영향을 차폐하는 지자기 차폐판을 갖춘 칼라 수상관에 있어서, 상기 프레임(7) 내면과 지자기 차폐판(8) 내면에 흑연을 포함한 전자흡수층(9)을 코팅한후, 흑화로를 통과시켜 상기 프레임(7)과 지자기 차폐판(8)표면 전체를 흑화시켜 새도우 마스크(6)표면에서 반사된 전자를 흡수하도록 구성된 것을 특징으로 하는 칼라 수상관.A phosphor screen, a shadow mask fixed at a position proximate to the phosphor screen, a frame supporting the shadow mask, an electron gun radiating an electron beam to each pixel of the phosphor screen through the shadow mask, and an electron beam emitted from the electron gun In a color water tube having a geomagnetic shielding plate which shields the influence of geomagnetism, the electron absorbing layer (9) containing graphite is coated on the inner surface of the frame (7) and the inner surface of the geomagnetic shielding plate (8), and then passed through the blackening furnace. A color receiving tube, characterized in that the entire surface of the frame (7) and the geomagnetic shielding plate (8) is blackened to absorb electrons reflected from the surface of the shadow mask (6). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
