Abstract

본 발명은 쉴드컵 후방면의 통공을 따라서 반경방향으로 서로 대향하여 돌출되는 사각판 형상의 보정전극이 일체로 형성되므로써, 전자빔의 방사시 보정전극에 의한 수직방향으로의 전자빔의 발산작용이 정확하게 이루어져 포커스 특성이 향상되므로 인해 전자총의 신뢰성을 향상시킨 것이다.According to the present invention, since the square plate-shaped correction electrodes protruding from each other in the radial direction along the through hole of the shield cup rear surface are integrally formed, the diverging action of the electron beam in the vertical direction by the correction electrode is precisely performed when the electron beam is emitted. Since the focus characteristic is improved, the reliability of the electron gun is improved.

이를 위해, 본 발명은 쉴드컵(1)의 R,G,B 전자빔이 통과하는 통공(2)을 따라서 서로 대향하여 돌출되는 사각판 형상의 보정전극(3)이 일체로 형성된 음극선관용 전자총의 쉴드컵이다.To this end, the present invention is a shield of a cathode ray tube electron gun formed integrally with a rectangular plate-shaped correction electrode 3 protruding from each other along the through hole 2 through which the R, G, B electron beams of the shield cup 1 pass. It is a cup.
