Abstract

본 발명은 음극선관의 전자총에 관한 것이다.The present invention relates to an electron gun of a cathode ray tube.

본 발명에 따른 음극선관의 전자총은, 열전자를 방출하는 음극이 전극의 빔통과공의 중심축에 대해 소정각도 경사진 중심축선을 갖는 복수의 열전자방출면을 구비하고 있으므로, 높은 전류밀도 상태에도 대응할 수 있게되어 음극의 수명이 연장될 뿐만 아니라, 휘도가 향상되게 된다.The electron gun of the cathode ray tube according to the present invention has a plurality of hot electron emission surfaces having a central axis inclined at a predetermined angle with respect to the central axis of the beam through hole of the electrode, so that it can cope with a high current density state. This enables not only the life of the cathode to be extended, but also the brightness is improved.
