본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 (나)(다)(라)는 본 고안의 전자총의 각기 다른 실시단면도이다.2 is a cross-sectional view showing different implementations of the electron gun of the present invention.

Claims (3)

전자빔(6)을 형광막(8)으로 향하여 방출하는 캐소드(10)를 구비하고 이 캐소드(10)와 형광막(8) 사이에 다수의 전극이 일렬로 배설되며 이 전극 중 적어도 2개의 전극들이 전기적으로 서로 연결되어 정전렌즈를 형성하는 전자총(5)에 있어서, 상기 정전렌즈를 형성하는 2개의 제5, 제6전극(25)(26)의 대향면에 통과공이 없는 개구부(30)(30a)를 형성하여 대구경주렌즈를 형성함을 특징으로 하는 칼라수상관용 전자총.A cathode 10 which emits an electron beam 6 toward the fluorescent film 8, and a plurality of electrodes are arranged in a line between the cathode 10 and the fluorescent film 8 and at least two of the electrodes In the electron gun 5 which is electrically connected to each other to form the electrostatic lens, the openings 30 and 30a having no through holes in opposing surfaces of the two fifth and sixth electrodes 25 and 26 forming the electrostatic lens. Electron gun for color water pipes, characterized in that to form a large diameter lens. 제1항에 있어서 상기 정전렌즈를 형성하는 2개의 제3, 제5전극(23)(25)의 대향면에 개구부(40)(40a)를 형성하여 상기 정전렌즈를 대구경 접속렌즈(LA)와 소구경 발산렌즈(LB)로 형성함을 특징으로 하는 칼라수상관용 전자총.The method of claim 1, wherein the openings 40 and 40a are formed in opposing surfaces of the two third and fifth electrodes 23 and 25 forming the electrostatic lens, so that the electrostatic lens is connected to the large-diameter connecting lens LA. An electron gun for a color receiver, characterized in that formed by a small-diameter divergent lens (LB). 제1항에 있어서 상기 정전렌즈를 형성하는 2개의 제3, 제5전극(33)(45)중 그 대향면에 개구부(40)(40a)를 형성하고 상기 제5전극(45)의 타측에도 개구부(30)을 형성하여 비대칭 대구경주렌즈(AEL)를 형성한 것을 특징으로 하는 칼라수상관용 전자총.The method of claim 1, wherein the openings 40 and 40a are formed on opposite surfaces of the two third and fifth electrodes 33 and 45 forming the electrostatic lens, and the other side of the fifth electrode 45 is formed. An electron gun for a color image tube, characterized in that an opening (30) is formed to form an asymmetric large-diameter lens (AEL). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
